### I. Isotopes

Nobody said anything for a while after that, and then Ilen Vosse asked whether he could have a week.

He asked it of the room, which was a stone chamber under a byre with four people in it and an object on a bed of dressed stones, and the room did not answer, because the only person in it who could answer was sitting on the bottom step with her arms round her knees and had been for nine hours.

"A week," Marenne said.

"Six days. I can do it in six if nobody makes me sleep."

"You were given a day."

"I was given a day to look at it and I have looked at it," said Ilen, "and I now know eleven things I did not know this morning and every one of them has made me stupider, and I am not going to be able to live if I go up that ladder tonight."

Marenne got off the step.

"I'll tell you in the morning," she said, and went up, and the hatch shut, and the lamp went on doing what lamps do.

· · ·

Kyra wrote the letter that night in the appalling building, at a table she had eaten at for two years when she was nineteen, with a heating system ticking somewhere below her that had been ticking in exactly that rhythm for twenty-one years.

It ran to eleven lines.

She had written to Marenne Vey twice in her life and had been written to twice, and the four letters between them had been about instruments and about a daughter and about a knee that did not work in cold weather, and not one of them had contained the word Sorin. That had not been an agreement. Neither of them had ever proposed it. It had simply become the shape of the thing, the way a path becomes the shape of a field.

The letter Kyra wrote said that the man downstairs was the best instrument anybody on Sethal had ever built out of a person, that he had been right about a dead man since he was eighteen and had been laughed at for twenty-four years, and that he would not touch the object, and would not photograph it, and would do nothing that anyone at Ossen said he could not do. It said Val had nothing left to spend and knew it.

And then the last line, which she looked at for some time before she let it stand.

*I am asking on my own account, and not on hers, and you know what it costs me to say that.*

She walked it down herself in the dark.

· · ·

The answer came at the fourth hour of the morning, verbally, by way of a boy of about fourteen who had been made to come up the road and did not know why.

"He's got six days," the boy said. "And she says the woman who wrote can come and sit in the room if she wants, and the other one can't."

Kyra put her hand over her mouth.

"Right," she said. "Thank you."

"Is one of you the one who took things?"

"Yes."

"Which one?"

"Not me," said Kyra Davan, and gave him a coin he had not asked for, and went and woke Val up and told her the first half and not the second.

Val found out about the second half on the third day, from Ilen, who had assumed everybody knew.

She said nothing about it at all. She spent the six days on the surface, walking the valley with a field kit she was not using, and at the end of each day she came back and asked four questions and listened to the answers, and did not once ask what the room was like.

· · ·

Here is what they had at the end of the six days.

The object was lattice. Closed-cell, grown rather than cast, with the cell walls a third thinner than anything the yards above Aventhal had managed in eleven years of trying. It had been broken off something larger along a line that was not a fracture in the ordinary sense: the material had not shattered, it had *stopped*, the way a poured thing stops.

The vitrification on the face had run in one direction and set. Ilen would not say what would do that. Ilen, who would say anything about anything to anybody, sat down on the stones on the fourth day, looked at the run of it for about an hour, and said he would rather be wrong in eleven years than stupid in front of two women tonight.

The isotopic ratios gave four thousand years, plus or minus a century and a half.

And the eleven marks in the unmelted band were a hull number and a date in a reckoning one man had invented and told nobody, and Ilen read them the way a person reads their own handwriting, and cried twice doing it and apologized both times.

· · ·

On the last evening Kyra sat on the bottom step with the lamp low and asked the question that had been sitting in her since the first hour.

"Where's the rest of it?"

"Ah," said Ilen.

"That's a piece of a hull, Ilen. A door's worth. You don't lose the rest of a hull."

"No."

"So it came down somewhere and the Vey found this and the rest is in a valley under four thousand years of dirt, and somebody ought to be able to—"

"Nothing has ever been dug up on this plateau," Ilen said.

Kyra stopped.

"There is no crater. There is no scatter. There is no burn layer, no metal, no second piece, not one fragment in four thousand years of people turning the same eleven fields over by hand, and I asked the question you are asking on the first afternoon and I have been asking it since." He had his chin in that position. "They have been farming on top of this since before Aventhal. If there were a ship here they would have found it with a plow."

"Then where is it?"

"Somewhere else," said Ilen Vosse.

The lamp ticked. Above them, faintly, eleven people who lived in that house moved about in it, being polite.

"Say that properly," Kyra said.

"I can't yet." He looked up. "That's the whole trouble. I have a piece of a vessel that is four thousand years old and made better than we can make it, and a man who took the vessel out and did not arrive anywhere anybody has ever looked, and no wreck. And I have a shape in my head that accounts for all three of those and I would sound like a lunatic saying it out loud in a cellar, so I am going to go home and do the arithmetic first."

"How long?"

"Two months."

It took him three.

*— end of chapter one —*

### II. Eleven Days

On the fifth of the six days a woman of about ninety came down the track from the upper holding to find Vaelith Sorin, who was standing in a field doing nothing at all with a field kit.

Val knew her at once, which surprised her. She had seen the face for four hours in a stone hall six days earlier, at the back, near the door, and it had asked her which cup.

"Narra Vey," the old woman said.

"I remember."

"You'd remember the question."

"Yes."

"It was a good question and I'd thought of it in the night and I was pleased with it," said Narra Vey, and sat down on a wall with the care of a person who has calculated the whole descent in advance. "Sit down. You're too tall standing and I've a thing to say and it'll take a while."

Val sat down on a wall on a plateau with no sea anywhere and put the kit in the grass.

· · ·

"You've got the piece out of the ground," Narra said.

"It hasn't been moved."

"I know it hasn't. I'm telling you what's happened, not asking." She looked out at the valley, which had eleven fields in it and a road. "Do you know what we say about it?"

"Nobody has told us anything about it."

"No. Nobody would." The old woman's hands were on her knees. "It isn't a secret, you understand. It's not hidden and it's not holy and there's no ceremony round it and the house above it is a byre. You could have asked any child on this plateau and got the same eleven words."

"Then why has nobody—"

"Because nobody asked us," said Narra Vey, "and because the last people who came here and were interested in us took things out of our arms in a shed and did not say what for."

Val did not look away.

"That was me," she said.

"I know it was you. I was in the hall." Narra made a small impatient movement. "You stood on a floor for four hours and answered a girl of sixteen better than you answered the men, and I have been thinking about it every night since, and I am ninety-one and I do not have the nights to spare."

· · ·

What she said then, Val wrote down that evening in the appalling building, twice, once from memory and once again the following morning to see whether the two agreed. They agreed to four words.

*For eleven days the sky stood in two places. The high field was two fields. A woman went out to the animals in the morning and came back in the morning. Those who went out in it came back wrong in the reckoning, and the ones that mended were the ones that had somebody. And on the eleventh day the sky closed and there was a new thing in the ground.*

"That's the whole of it," Narra said. "There's a version with more in it but it's later and somebody's made it nicer."

"How old?"

"Old as we are. Four thousand years, near enough, and we count by names and I could give you the names if you had a month."

Val was looking at her own hands.

"Do you know what any of it means?"

"It means the sky stood in two places," said Narra Vey, with the flat patience of a woman explaining weather to a child from the city. "Nobody here has ever thought it meant anything else. It's you lot who need it to be a story about something."

· · ·

Val went through it eleven times that night and four more on the lander.

*A woman went out to the animals in the morning and came back in the morning.* Not the following morning. The same one. A sentence that had been carried for four thousand years by people who would have dropped it in a generation if it had not been strange enough to keep.

*Came back wrong in the reckoning.* Wrong in the counting. Wrong in the numbering. She sat with that one for an hour with the cabin dark and everybody else asleep.

And then the other one, which she did not write down at all on the first night, and which she wrote down on the second night and then sat and looked at for some time.

*The ones that mended were the ones that had somebody.*

She had heard a version of that before. Everybody on two worlds had heard a version of that before. It was in a ceremony eleven thousand people performed on a plateau, and had been quoted at her in a common room at nineteen by a woman who thought it was charming, and had been printed in four separate anthropological surveys as an example of pastoral sentiment.

*Two enter. Neither completes without the other. One carries what the other cannot.*

Val Sorin sat in a dark lander cabin four hours out from Thennet with a notebook on her knee and did not write the next line, because she could hear exactly how it would sound in a room, and because she had spent eighteen years learning what happens to a woman who says an enormous thing before she can prove it.

She turned the page instead and wrote, in the flattest language she owned: *Ask Ilen whether an interval has a duration that can be reported by the people inside it.*

*— end of chapter two —*

### III. Two Endpoints

Ilen Vosse took three months and then called nine people into a room at Corran Vayr and shut the door, which he had never done in his life.

The room held eleven at a squeeze. There were nine in it: four from the drive faculty who had been doing his arithmetic for him and had come out of it looking hunted, Kyra, Val, a woman from the yards who had built more hull than anybody alive, and Hollis from orbital, who had come down on the coach from Solara in the wet and had not been told why.

"Right," said Ilen. "I'm going to say four things and three of them are going to sound stupid."

· · ·

The first thing was the fifteen seconds, which everybody in the room had known about for three years and had stopped thinking about, the way you stop thinking about a noise in a house.

The second was that a fold has two parts. Not two stages — two *parts*, running at once: the part that moves position, which forty years of work had described to eleven places, and a second part that nobody had ever had to name because in an ordinary fold it lasts for a length of time too small to have a unit.

"Call it the interval," Ilen said. "Somebody will call it something better later and I'll be delighted."

The third thing was what happens inside it.

He put it up on the plate the way he put everything up, badly, with his own handwriting crawling round the edges, and talked for forty minutes, and at the end of the forty minutes the woman from the yards said, "You're telling me the ship doesn't have an address."

"Yes."

"For fifteen seconds our ship was not anywhere."

"No — no, that's the bit everybody gets wrong and I've been getting it wrong for a year." Ilen had both hands up. "It isn't nowhere. It's *both.* It has a departure and it has an arrival and for the length of the interval it has not been decided which of them it belongs to. The instruments aboard were not malfunctioning. They were reporting two true things."

"One star tracker on the home sky and one on the far sky."

"And a third on a sky that is not in the catalogue, which I cannot account for and am not going to try to in front of nine people."

· · ·

The fourth thing took him four minutes and it was the one that emptied the room afterward.

"Sorren Dael went out with an interval of eleven days," Ilen said.

Nobody moved.

"That is what the eleventh series *is.* It isn't a longer fold. It's a fold with the interval opened up, which is the only way anybody has ever got past the range limit, and it is why his method looks insane if you read it as an extension of the first ten, which is how I read it for twenty-four years and how everybody has read it for four thousand." He wiped his hand down his face. "Eleven days. Eleven. It's in the notation twice and I read it as a duration of transit both times."

"For eleven days the sky stood in two places," said Val.

Everyone in the room turned round.

"That's a Vey saying," she said. "It is four thousand years old and there is a version of it a child on that plateau could give you, and it describes a high field that was two fields, and a woman who went out in the morning and came back in the morning, and a new thing in the ground on the eleventh day."

Hollis said, "That's a farming story."

"It's an observation," Val said. "It is an entirely accurate observation made by people with no vocabulary at all, and it has been sitting in the anthropological record for a hundred years under *pastoral idiom,* and the reason nobody has ever put it against a fold notation is that nobody has ever had both on the same table."

· · ·

It was Kyra who said the last of it, because Kyra was the only person in the room whose whole professional life had been the difference between two numbers.

"Then there are two endpoints," she said.

Ilen turned round very slowly.

"Say that again."

"You've just told a room that for eleven days a vessel had a departure and an arrival and no decision between them. Fine. What comes *out?*" She was on her feet without having got up. "You keep saying the ship. It isn't a ship, it's a hull full of separate objects in a bag. What if the bag doesn't have to come out in one place?"

"Kyra—"

"There is no wreck on Thennet. There is no crater, no scatter, no burn, nothing in four thousand years of plowing, and there is a door-sized piece of his hull under a byre with his hand on it." She had her palm flat on the table. "And there is no Sorren Dael. Not at the solution. Not anywhere. Four thousand years and nobody has ever found so much as a signal."

The room was extremely quiet.

"You're saying the man came out somewhere else," said Hollis.

"I'm saying a piece of his ship came out here and I would like somebody in this room with better arithmetic than mine to tell me that isn't possible."

Nobody did.

Ilen Vosse sat down on the edge of the table, in front of nine people, and looked at the far wall for the better part of a minute.

"It put him somewhere," he said. "Which is different."

He had said that at nineteen, to two students, on a night when he had been given a basement and a dead man's papers, and Val remembered the whole room it had been said in, and the fact that nobody else in this room knew what they had just heard made her want, for the first time in years, to go and sit somewhere alone.

*— end of chapter three —*

### IV. The Line That Left

Marenne Vey came down to Sethal in the first month of the following year, which no member of the Ossen holding had done in the memory of anybody living, including her own.

The institute did not know what to do with her and did it badly. There was an offer of the long room and a lunch, which she declined; there was a proposal from the Assembly, relayed by a man who had never met her, that she might care to address a committee, which she did not answer; and there was a physician sent out from Aventhal on the first afternoon to see whether the altitude difference was troubling her, who came back down again reporting that she had been shown the door in four words.

What she wanted was a room with three people in it.

· · ·

They gave her Val's office, because it was the only room at the institute that did not have a committee attached to it, and she sat down in it with her back to the window and did not take her coat off.

"I'll say it and then I'll go," Marenne said. "I've spent nine months deciding to and I'm not going to spend the afternoon on it as well."

"We're listening," said Kyra.

"You'll want to write it down and I'd rather you didn't yet." She looked at Ilen. "You especially."

"I have nothing on me," Ilen said, and turned out his coat, which had eleven things in it, all of them pens.

Something happened to Marenne Vey's mouth that was very nearly a smile, and did not arrive.

· · ·

"We have had no one in and no one out for four thousand years," she said. "You know that. It's in every survey anybody has ever written about us and it is true."

"It's the first line of all of them," said Val.

"It's true with one exception and the exception is not a secret, it is an *agreement.*" Marenne had her hands on the arms of the chair. "A family left. Eleven of them, or nine, depending on who tells it. It was a long time ago and not four thousand years ago — it is in the names, and I can give you the names, and the last of them are eight generations back."

"Why did they go?"

"Because they could feel it."

Ilen sat forward about four inches and did not interrupt, which cost him something.

"That is not a figure of speech and I want to be careful, because you will make it into one." Marenne's voice did not change at all. "There are people born on that plateau every generation or so who know where the piece under the byre is without being told. Not by the house. Not by the ground. They can stand in a field in the dark and turn round and point at it. When they are small it frightens people and when they are grown it is a nuisance to everybody including them, and there has never been a single thing anybody could do about it."

"And they left," Val said.

"They asked to. There was a discussion and it lasted a long time and at the end of it the holding agreed that they should go, and agreed to the other thing as well, which was that we would stop saying them." Marenne looked out of the window at a campus she had never seen before. "Not erase. We don't erase. We simply stopped putting them in the names. Everyone agreed, including them, and it was done out of kindness in both directions, and it means that I am the first person in eight generations to say any of this to anybody who is not Vey."

"What did it cost you to come here?"

"That's my business," said Marenne Vey.

· · ·

They had the rest of it inside the hour and it was Kyra who put the last piece on the table, out of a notebook, from a conversation with a clerk in a registry at the institute four years earlier.

Two people had come asking after Alexander Muler at the west desk before he went. Neither from the institute. Neither of them women. Nobody had kept a book on it.

"That's how he knew," Kyra said. "Somebody found him and told him what he was. He's from that line — five or six generations off the plateau, in a city, with a name that isn't a Vey name, working in materials and going quietly gray and being very good at getting people to like him. And one day two men he had never met knocked on his door."

"He put three figures in the back of a notebook," said Val. "Thennet. The Dael archive. And a solution nobody has ever seen anything at."

"He wasn't hiding from anybody. He was *looking.* He came to a fold institute because that is where you would go."

Ilen had not said anything for eleven minutes, which was a record.

"And his medical record," he said.

"There is no medical record," said Val, "and there never was one, and we spent four months proving that nobody did it on purpose."

· · ·

The last of it was the part they did not get.

He had left Sethal. That much was findable and they found it in eleven days: a passage worked for on a supply hauler out of Hessen Point in the eleventh month, four years before, with his own name on the manifest and no attempt at anything else, and an ordinary crossing to an ordinary place four days out.

After that, nothing.

Not a death. Not a disappearance, not a hint of one, no report, no claim, no file. A man walked off a hauler at a working port and went about his business and the paper stops, the way paper stops about most people who are not important, and they turned that port over for four months and found a room he had rented for eleven weeks and paid up and left clean.

"He's alive somewhere," said Kyra, at the end of the four months.

"He's a man of thirty-eight who is very good at being liked," Val said. "He could be four hundred years old and in a town nobody has heard of, and we could spend the rest of our lives on it, and we would be doing it because it is easier than the other work."

"That's not a reason to stop."

"No. It's a reason to know why we're going."

They stopped. It took Kyra a fortnight to agree to it and she never entirely did, and neither of them ever said out loud that there were two other people who were going to want that answer one day and were three.

*— end of chapter four —*

### V. Distance Is Not the Variable

What the eleven marks under the byre actually gave them was a date, and what the date gave them was the key to a filing system.

Sorren Dael had kept his own reckoning. Everybody had always known that; it was the first thing anybody said about the archive after they had said how beautiful it was. He had a year-count that began at something nobody could identify and ran in elevens, and four generations of scholars had treated it as an eccentricity and converted out of it where they could and shrugged where they could not.

The hull number on the object had a date beside it in that reckoning, and the object had an isotopic age, and between the two of them Ilen Vosse had, for the first time in four thousand years, one fixed point.

It took him a fortnight to convert the whole archive.

Then he stopped talking to anybody for a week, and at the end of the week he sent a message to Kyra at Solara that said, in its entirety: *the series is not eleven attempts at one thing.*

· · ·

It was not eleven attempts at one thing.

It was ten solved problems and one unsolved one, and once the dates were right you could see him doing it, year by year, in order, like a man going up a staircase in the dark.

The first ten series were distance. All of them. Every one of the ten was an increase in range and every one of them worked and every one of them was flown, by him, in the little vessels the yards had turned out for nine hundred years, and the last of the ten had put a man four times further out than anything Sethal would manage again until the century Kyra was born in.

And underneath all ten, from the fourth onward, there was a second set of numbers that nobody had ever been able to make sense of because nobody had ever had the dates.

They were durations. In seconds.

"He was measuring the interval," Kyra said, standing in a cold room at the eleventh hour with a plate in front of her. "From the fourth series. Forty years before he ever tried to open one."

"He was measuring it and he was frightened of it," Ilen said on the link, from a room four hundred yards away that he had not left in two days. "Look at the fourth column. Kyra, look at the fourth column."

· · ·

The fourth column was what he had put in the interval.

Not instruments. He had instruments and he used them and they told him nothing, because an instrument inside an interval is a thing with two true readings and no opinion about either. So he had stopped asking instruments and started asking the only thing that has an opinion.

He had flown living material. Seed stock and gut cultures and, in the last four series, small animals; and he had flown them at intervals he could set, and he had written down what came back, and he had done it for thirty years.

Below eleven seconds, everything came back.

Not unchanged, and he was scrupulous about that: there was a column of small oddities that ran all the way down, things a shade out, things a fraction early, a set of cultures at nine seconds that had done something he described in a word nobody could now translate. But everything came back, and everything went on living, and the oddities did not compound.

Above eleven seconds the column changed.

He did not use a word like *dead.* He used a phrase, four times, and Ilen had been staring at it for two days, and it converted to something very close to *came apart in the ordering.*

· · ·

"Say the shape of it," Val said, on the wall at the water house, on a Fourthday with the orchard doing nothing in particular.

"The shape of it is that distance is free," said Kyra. "Distance costs energy and it costs money and it does not cost you anything that matters. You can fold a hull four times further out than anybody has ever gone and it will not do one thing to the people inside it, because the position part is the part he solved ten times."

"And duration."

"Duration is everything. The longer a thing is inside the interval, the more chances its state has to come back together in the wrong order. Matter hardly notices, because matter is not doing anything. A rock is a rock in either endpoint." Kyra had her hands out on her knees. "A living body is not a thing, it's a process. It is eleven thousand processes that have to stay in step with each other, and every one of them has to agree about what time it is."

Val turned the cup round on the stone.

"And on Sethal," she said.

"Say it, you're the biologist."

"And on Sethal we are worse than most things, because what our cells do at the bottom is *timing.*" Val was looking down the orchard. "Everything about how a Sethal body runs is resonance. It's coordination. It is the one system in the known universe that you could describe, without stretching anything, as an agreement about what time it is."

Somewhere behind the water house a pump started and ran and stopped.

"He wasn't trying to go further," Val said. "The eleventh series isn't distance at all."

"No."

"The first ten were how to move a man. The eleventh is how to keep him."

*— end of chapter five —*

### VI. Eleven

They put it in front of Ilen on a Secondday in the second month, in his own room at Corran Vayr, because Kyra said it was not a thing to do on a link and Val agreed with her before she had finished the sentence.

He was forty-three and thinner than he had been and in the best year of his professional life, and he had a chart of the fourth column on the wall behind him that he had drawn himself, badly, and he was delighted to see them.

"You've got something," he said. "Both of you have got the face. It's a good face. Sit down."

"Ilen," said Kyra.

"I know what it is." He was still smiling. "I've known for eleven days. I have been waiting for somebody else to say it, because I have not been able to make myself write it down."

Val put the sheet on the table anyway.

Eleven seconds, in Dael's own hand, converted, checked twice, the last safe interval he ever recorded for living material.

And underneath it the number everybody on the planet had celebrated for four years, that had been in the Assembly's own statement and on the front of the news sheets and in a song somebody at the yards had written that was funny for about a month.

Fifteen.

· · ·

Ilen looked at the two numbers for a long time.

Then he did the thing nobody in the room had ever seen him do, which was to sit down slowly and completely and put both hands flat on his knees and stop.

"There were four people on it," he said.

"Yes."

"I put the proposal up four times. The fourth time I stood in the long room at Solara and told a committee that a crewed flight was the only honest test, because an empty hull tells you what happened to a hull." He was looking at the wall. "That's a quotation. I can give you the day."

"Ilen—"

"Jalen Renn," said Ilen Vosse. "Lira Osk. Torrin Marr. Senara Tevel. I taught all four of them. Osk was in my second-year class and slept through eleven weeks of it and got the highest mark I have ever given anybody. Marr's wife makes a thing with fish in it that I have eaten at their table nine times." He stopped. "They walked out of it. There is a physician's report nine days long and there is nothing in it. Nothing whatever."

"That's true and it stays true," Val said.

"I know it stays true. I am telling you what I have in my head, which is four people being examined for nine days by a man looking for a thing he had no name for."

· · ·

Kyra said the hard thing, because Kyra always said the hard thing.

"It might be nothing."

"It might."

"Dael's eleven seconds is a limit for what he flew, and what he flew was seed stock and gut cultures and four animals in a box, and none of them is a person and none of them was inside a hull with a field round it." She had not sat down. "You could line up eleven reasons why fifteen seconds in one of our vessels is not the same fifteen seconds and four of them would be good."

"And the fifth?"

"The fifth is that a man who spent thirty years measuring one number wrote it down and drew a line under it," said Kyra, "and we went four seconds past it with four people inside and we did not know we had done it until three years afterward."

Ilen got up. He went to the window, which looked out on a yard and a wall and, beyond it, the sea he had lived beside for twenty-five years and had never once mentioned.

"There's the other thing," he said.

"Say it."

"I have been not saying it for eleven days and I would like you to notice that I am saying it now, in a room, to two people who can make it my problem." He turned round. "The second flight is scheduled. The appropriation went through the Assembly at the turn and the hull has been growing at the yards since before we went to Thennet. It goes further, which is the whole point of it and which does not frighten me at all."

"And the interval," said Val.

"Longer," said Ilen Vosse. "We do not know how much longer and we have never had a reason to care. Nobody has ever modelled it, because until eleven days ago the interval was a thing that lasted no time and did nothing, and we have all been standing on it for four years calling it a discrepancy."

The room was entirely quiet.

"When?" Kyra said.

"Fourteen months."

*— end of chapter six —*

### VII. The Four Who Walked Out

Val's group had held the return-hull characterization from the beginning, because four years earlier Ilen Vosse had said, in a room, that if that thing came back with anything living on it that had not gone out on it he wanted a biologist saying so.

It was unglamorous work and her twelve had been doing it for three years: swabs off surfaces, the water plant, the air, the four sealed sample racks that had gone up as an afterthought and had turned out to be the most interesting objects in the system. Every one of those belonged to her.

The crew did not.

Four people had been assayed before they went and again afterward, at length, by a program physician, and those four sets of panels sat in a medical registry with a door on it, and Vaelith Sorin had no more right to them than she had to anybody else's.

She could apply. There was a form and a committee and a schedule, and Nesh worked out the timings in an afternoon and came back with four months at the optimistic end.

The second flight was in fourteen.

· · ·

She went up to Hessen Point on the Thirdday and found Jalen Renn in a yard behind the strip, in the rain, arguing with a loadmaster about a mass budget, and stood at a distance until he was finished, which took a while, and enjoyed it more than she expected to.

He was thirty-four and a head shorter than her and built like a man who did not stop moving, and he had the specific happiness of somebody who has already got the only thing he wanted.

"You're the biologist," he said. "The hull one. Sorin."

"Yes."

"You found the thing on the dish. Vosse has told me about the thing on the dish four times and I did not understand it any of the four and I'd very much like a fifth go."

"I'll do that," Val said. "I'm here to ask you for something first, and I want to do it properly, so I'd rather you let me say the whole of it before you answer."

Renn put his hands in his pockets and stood in the rain and let her get to the end of it.

· · ·

She told him about the interval. She told him about eleven and fifteen. She told him that nothing had happened to him or to the other three, that the physician had looked for nine days and found nothing, and that she had no reason to believe anything was wrong with any of them and was not suggesting there was.

And then she told him that she wanted his panels — before and after — and that she had no right to them, and that the proper way to get them would take four months and the flight was in fourteen, and that if he said yes she would be looking at his body without an institute behind her and he should understand exactly what that meant for him and for her.

"And what am I looking for," he said.

"I don't know."

"That's an honest answer and I'd like to be clear I'm not complaining about it."

"I'm looking for anything that moved," Val said. "If something moved I will not be able to tell you what it means, possibly for years. And it will be on a sheet with your name on it in a building you do not work in."

Jalen Renn thought about it for about four seconds.

"Yes," he said. "Obviously yes. Have the lot."

"Renn—"

"No, I've heard you, and you were very thorough, and I want to say two things and then I'm going to go and shout at that man again." He wiped the rain off his face with the flat of his hand. "The first is that there are three other people and you'll have to ask them yourself, and Tevel will say yes and Marr will want his wife in the room and Osk will make you work for it and then say yes."

"And the second?"

"The second is that I'm going again in fourteen months," said Renn, "and whatever you find, I'd like to know before I go. Not so I can decide. I've decided. Just so it's me that knows it and not a committee."

He went back to the loadmaster.

Val stood in a wet yard at Hessen Point for a moment with her hands at her sides, being aware that she had just done, at forty-one, in four minutes, in the rain, the thing she had not done at twenty-two in a shed on a plateau with nineteen people's tissue in her bag.

It had not been difficult. That was the part she took home with her.

· · ·

She told Belu the same evening, standing up, before he could ask.

"You should have come to me first," he said.

"You'd have said no."

"I'd have said no and I would have been right, and then I would have spent four months getting you a yes."

"The flight is in fourteen."

Toven Belu took his glasses off, which was what he did instead of raising his voice.

"I am not going to stop you," he said. "I want that on the record between us, because in about a year somebody is going to ask me whether I knew, and I am going to say that I knew on the day and did not stop it." He put them back on. "And the same person is going to ask whether the consent was obtained by the head of a group at this institute in a yard, in the rain, with nobody present. And I will have to say yes to that as well."

"I know."

"Do the work, Val," said Belu. "And write down every single thing you do while you do it, because one of these days that is going to be all you have."

· · ·

Marr wanted his wife in the room. Tevel said yes on the link inside a minute. Osk asked eleven questions, four of which Val could not answer, and took a fortnight, and then sent a note that said *fine, but I want a copy of everything, including the parts you think I won't understand.*

Nesh stood at the bench and wrote down every step.

It took nine days, and on the seventh Val stopped and sat back and did not say anything for so long that Nesh put her pen down.

In three of the four, nothing. Not a thing. Four panels' worth of a tediously healthy adult.

In Jalen Renn, four regulatory markers had moved.

Not far. Not into the range she had spent three years looking at in her own daughter and in Kal. A fraction of the way, in exactly the direction she would have drawn if somebody had handed her a pencil and asked her what the beginning of it would look like — and by a margin small enough that a careful person could call it drift and sleep perfectly well.

"Is that a finding?" Nesh said.

"It's one man," said Val. "It is one man, once, by a margin I would not accept from you."

She took the sheet to the window and stood with it for a while.

"And it is a man who had never been within four hours of Thennet in his life," she said, "and who spent fifteen seconds somewhere, and came out of it a small distance closer to eleven thousand people on a plateau."

*— end of chapter seven —*

### VIII. What Came Back

The rest of the manifest had been sitting in four crates in a cold room at Solara for three years, and the reason nobody had looked at it properly was that everybody had already looked at it and found nothing wrong.

They went back through all four crates in the eighth month, with the dates converted and the interval on the table and four people's assays in a locked drawer, and this time they were not looking for damage.

They were looking for things that had kept the wrong time.

· · ·

A timing crystal out of the secondary reference had a defect density that belonged to a component about nine years old. It had been grown eleven months before the flight. It had been checked on return by a man who logged it as within tolerance, because it was within tolerance, because the tolerance on a crystal of that class is enormous and nobody had ever had any reason to ask a crystal how old it felt.

A strip of hull plating off the forward spar had aged. Not much — a fraction, at the limit of what Kyra could resolve, and she resolved it four times and then had it done by somebody who did not know why.

And a second strip, off the aft spar, eleven feet away, had aged by a slightly smaller fraction.

"That's the worst one," Kyra said.

"Explain it to me as though I didn't sit through the last forty minutes."

"If the whole ship came back four months old, that's a story. It's a strange story and I'd want to lie down, but it's one thing happening to one object." She had the two figures on the plate, side by side, with the difference between them underneath. "This is not one thing happening to one object. This is one *ship* in which the front and the back did not have the same amount of time happen to them."

· · ·

And then the sample racks, which were Val's, and which she had been putting off.

There were four of them and they had gone up as an afterthought, the way a rack of environmental monitors always goes up as an afterthought, and three of them were dull.

The fourth had a culture dish in it.

It was not an experiment. Nobody had designed it. It was a control: a standard reference culture, the most boring organism anybody at Solara had, put aboard so that if the air plant did something interesting on the way there would be a baseline to compare it against.

Val had counted the generations three times before she let Nesh see it.

The dish had been out of the incubator, aboard the hull, for four minutes and eleven seconds.

Most of what was in it had lived four minutes and eleven seconds.

A part of it — a patch, a fraction of a percent, not localized to any one place — had gone through something in the region of sixty generations. Another part had done perhaps a dozen. And in one corner of the dish there was a population that had done nothing whatever, not a division, not a shift, less than four minutes' worth of anything, as though it had been set down and picked up again.

Sixty generations of that organism is a fortnight.

"Fourteen days," said Nesh.

"In four minutes."

"In fifteen seconds," Val said, "and that is the part I want you to hold on to, because the four minutes were ordinary and the fifteen were not."

· · ·

They put it in front of Ilen on the Fourthday and he went very quiet, and then he asked the question neither of them had been able to ask out loud for a week.

"Not uniform," he said.

"No."

"Not a gradient either. Not front-to-back, not warm-to-cold, not near-the-wall and far-from-it."

"I have looked for eleven kinds of gradient and it is not any of them," said Val. "It is not *anywhere.* It is a dish, and time did not happen to it evenly, and I can put my finger on the glass and tell you that here it was a fortnight and eleven millimeters away it was nothing at all."

Ilen sat back.

"So it isn't that the interval is long," he said.

"Say it."

"It's that inside the interval, duration is not a property of the ship. It's a property of every separate piece of what's in it." He had both hands over his mouth. "Oh, that's *horrible.*"

"Yes."

"That's horrible, Val. That is not a hazard, that is not a dose, you cannot shield anybody from that. There is no such thing as a safe duration for a body if the body does not have one duration."

"There is one," said Kyra, from the end of the bench, where she had been quiet for some minutes. "There's eleven seconds. It held for thirty years of a dead man's animals and it held for four people three years ago and it will hold for four more in eight months, and nobody has the faintest idea why, and that is now the only question in the world."

*— end of chapter eight —*

### IX. Ilen Vosse Will Not Have It Buried

The drive faculty's position was not cowardice, and that was the thing that made it difficult for four months.

It was this. Four people had gone out and come back and walked off the strip on their own feet, and a physician had gone over all four of them for nine days and found nothing, and three years later they were all still working and one of them was arguing with a loadmaster at Hessen Point every Thirdday. There was, at this moment, nothing whatever to warn anybody about.

What there was instead was a strange old number out of a converted archive, a crystal that felt nine, two bits of hull that disagreed by a fraction, a dish nobody had designed, and one man's regulatory markers a small distance out of a range that nobody but Vaelith Sorin had ever had a reason to look at — obtained, it would eventually be noticed, in a yard.

Put that in front of the Assembly and you do not get caution. You get forty years of work stopped by eleven people who have not understood a word of it, and a hull rotting at the yards, and a generation of the best minds on the planet going into orbital mechanics because the fold is finished.

Nobody said *bury it.* What they said was *not yet,* which is the same sentence with better manners, and there were four senior people saying it who had given their lives to this and were not fools.

· · ·

Ilen let them say it for four months.

He did not sulk and he did not campaign and he did not leak anything to anybody, and he went on running the faculty and losing two arguments a week to people he had trained, and on the whole it was the happiest year he had ever had, which several people afterward found difficult to forgive.

Then in the first month of the following year he wrote it up.

It ran to sixty pages. It set out the conversion of the archive, the fourth column, the eleven seconds, the fifteen, the crystal, the two spars, the dish, and — with four lines of description and no name — one crewman's shifted markers. It contained no recommendation of any kind, which is the most aggressive thing a document of that sort can do.

And at the top of it there was one name.

"Take mine off," Val had said, when he showed her the front sheet.

"It's off. It was never on."

"Ilen, half of that is my group's—"

"Half of that is your group's and all of it is the faculty's and the name on the front is mine," said Ilen Vosse, "and I want you to think for a moment about which of the two of us can afford it."

Val did not answer.

"You have a finding on your record," he said, more gently. "I have a fold. They cannot do anything to me that I will notice. They can end you in an afternoon and half of them would enjoy it, and I have watched that happen to you once already and I was twenty-two and I did nothing, so if you don't mind, I'll have the name."

· · ·

He did not put it through a friend. He put it through the faculty, up the proper stair, at the proper meeting, with the four senior people in the room who had been saying *not yet* since the spring, and he read the four paragraphs at the front out loud himself because one of them asked him to and he could not see a reason not to.

Afterward one of the four — a man of seventy who had taught him — stayed behind and told him he had just finished his own career for a rounding error.

"Possibly," Ilen said.

"You have no idea what they'll do with this."

"None at all. That's rather the point of writing things down."

"You could have waited a year. One year, Ilen. You'd have had the second flight, and if it came back clean—"

"If it comes back clean I will have sat on this for a year and been lucky," said Ilen. "I do not want to have been lucky. I want to have been a man who wrote it down when he knew it, and I would like to go on being that afterward, and I am fifty in six years and I have not got the constitution to be anything else."

He went home on the coach and slept eleven hours, which for him was a holiday.

· · ·

The document did one thing before anybody voted on anything, and it did it quietly, and it was the only win anybody got that year.

The second flight moved. Not because of a decision and not in a minute of any meeting: the hull needed four more months of growing, and then the yards found a scheduling difficulty, and then the appropriation's second tranche came late, and by the end of it the date had gone back by two years.

Nobody announced a deferral because nobody had deferred anything. Four senior people who had spent four months saying *not yet* had read sixty pages and had gone away and done what senior people do, which is nothing that can be pointed at.

"That's two years," Kyra said, when Ilen told her.

"That's two years."

"Will they use it?"

"Somebody will," said Ilen Vosse. "It won't be a committee."

*— end of chapter nine —*

### X. Say It or Manage It

They had the worst argument of their lives on a Fourthday in the grass below the water house with two children eleven feet away, and they had to conduct it in undertones.

The girls were four. Genie had found a stick and was explaining it. Kal had found a different stick and had no intention of explaining anything, and was watching a bird with the total attention of somebody who intends to do something about it later.

"He's put it up," Kyra said. "It's gone up the stair. That's the end of the argument, Val, it exists now."

"It exists inside a faculty."

"It exists."

"A document inside a faculty is a document. A document in front of the Assembly is a decision, and we are not ready to have the decision made for us by eleven people in a hall." Val had her hands round a cup. "I want another year."

"They fly in two years."

"I know when they fly."

"Then say what you actually want," said Kyra, "because from here it sounds like the woman who has been managing the truth since she was eighteen has found one more reason."

· · ·

Genie came over with the stick. There was an interval of about ninety seconds in which two women who had just said unforgivable things to each other admired a stick, and Kal came and stood against Val's knee and leaned, and Val put her hand on the back of the child's head without appearing to notice she had done it.

Then the two of them went off toward the trees and it started again.

"It's Renn," Val said.

"What about him?"

"He said yes to *me.* In a yard, in the rain, on four seconds' thought, because he is that sort of man." She put the cup down. "He said yes to a biologist looking at his panels. He did not say yes to his name going in front of the Assembly, and there is no version of this that goes public in which he is not named, because there were four of them, and one of them was the commander, and any child on this planet can count."

"Ilen took the name out."

"Ilen took the name off a sheet. There were four people on that hull and it is the most famous crew in four thousand years and every one of them has been photographed." Val's voice had not gone up at all and had gone somewhere worse. "Within a fortnight of that document leaving the faculty, everybody on Sethal knows that one of four people has something wrong with him, and the four of them will be asked at their own doors which one, and Renn will say it was him, because he will think that is the decent thing."

Kyra opened her mouth and shut it again.

"Then ask him," she said.

"I intend to."

"No — I mean that's the answer, Val, that's the whole answer. It isn't yours to weigh. You've been sitting on this for a month doing arithmetic about a man's life on his behalf."

"I am aware of what I have been doing."

· · ·

It was Kyra's next sentence that they both remembered.

"You did this to me," she said.

Val went still.

"In a room on the ground floor of the east range with a form and a man called Oren, twenty years ago, you decided what I could carry and you did not ask me, and you were right, and it cost me ten years of you." Kyra was not shouting. That was the thing Val thought about afterward: she was not shouting, and she was crying, and she went on talking in a level voice with the children in the trees. "And every single time since then you have known better and every single time you have been right, and I am telling you now, as the person who has been on the other end of it for twenty-four years — it does not matter that you are right. It is the not being asked. That is the injury. That is the whole of it."

The orchard did what it did.

"All right," Val said.

"Don't manage me either."

"I'm not." Val was looking at her hands. "You are correct. About all of it, and about me, and I have known it since a cold store and I have gone on doing it because it works."

"Val—"

"It works, Kyra. That's the thing nobody says out loud. It works nearly every time, and every time it works it costs somebody a piece of their life that they never get to know about." She picked up the cup and did not drink out of it. "I'll ask him. In front of Ilen, with the document on the table, and whatever he says is what we do. And if he says put my name on it, I will put his name on it, and I will not say one word to talk him out of it."

"And if he says bury it?"

"Then it's buried," said Val, "and four people go up in two years, and we live with what we did."

Kyra wiped her face with the back of her wrist.

"He won't say bury it."

"No," Val said. "He won't."

· · ·

They sat there a while longer without saying anything, which was not a thing either of them had ever been able to do comfortably.

Down in the trees Genie was shouting about something. Kal was not.

"I don't know how to do the next part," Kyra said, eventually.

"Neither do I."

"That's not reassuring from you."

"It wasn't offered as reassurance," said Val, and Kyra laughed once, wetly, and put her head back, and that was the end of it for that afternoon.

*— end of chapter ten —*

### XI. The Committee

They asked Jalen Renn in a room at Corran Vayr with the document on the table and Ilen at the end of it, and it took him about as long as it had taken him in the rain.

He read the four lines about himself twice. Then he asked what would happen to the four of them if it went up, and Val told him, in detail, without softening any of it: the naming, the doors, the years of being the man it might have happened to.

"And if it doesn't go up?"

"Then the second flight goes in eighteen months," said Ilen, "and the interval is longer, and nobody outside this faculty will have been told that there is a number."

"Right," said Renn. "Put my name on it."

"You don't have to—"

"I'd like everybody to stop offering me the other thing," he said, not unkindly. "I've been offered the other thing four times this year and I keep saying the same sentence. Put my name on it. If it's me, it's me, and then it's a fact instead of a rumor about four people."

He looked at Val.

"You asked me in a yard," he said. "Nobody has ever asked me anything in my life. Everybody I have ever worked for has decided and then told me afterward and called it a briefing, and you stood in the rain and made me listen to every word. So put my name on it, and if it costs you something, I'd like to be told, and I'd like to be told first."

· · ·

The committee sat in the eleventh month and it was a joint one: five from the drive faculty at Corran Vayr, five from Solara, and a chair from the Assembly who said almost nothing for two days and asked four questions on the third that were better than anybody else's.

Eleven people.

The science took a day and a half and survived it. Nobody attacked the conversion; nobody could, because Ilen had shown his working in a way that would be taught for two hundred years. Nobody attacked the crystal or the spars or the dish. A man from the yards spent an hour trying to kill the dish and gave it up in front of everybody and said so, which Val thought was the single best thing anybody did in three days.

The rest of it was about how they had come by things.

· · ·

It went in this order.

The Vey material first, which took most of the second morning: nineteen samples obtained without consent twenty years earlier, after a written refusal, from a population of eleven thousand people, by a woman sitting at the end of the table. Val answered every question about it. She had answered the same questions on a stone floor at Ossen for four hours, in front of a hundred and nine people who were owed it, and this room was not owed it and got the same answers anyway.

Then Renn's panels.

"In a yard," said a woman from the faculty. "At Hessen Point. In the rain."

"Yes."

"With nobody present."

"With nobody present."

"Sorin, do you understand what it looks like for a woman with a finding on her record to obtain a serving commander's medical panels by a private approach in a yard?"

"I understand exactly what it looks like," Val said. "It looks like what it is. The proper route was four months and the flight was in fourteen, and I decided that asking him myself was better than not asking him at all, and I told my director the same evening, and every step of the work after it is written down by a second person. And I would do it again, and I am aware that saying so does not help me."

The chair from the Assembly wrote something down.

And the woman from the faculty said, "Nobody is suggesting she is a liar. I am suggesting that a body of work which rests at two separate points on material this institute did not lawfully hold is not a body of work we can put in front of the Assembly, and that if we do, the first person to read it will not read the science."

It was, Val thought, the best argument anybody made in three days, and it was made against her, and it was correct.

· · ·

They voted on the third afternoon.

The Vey material was restricted to the faculty and to Solara's biology building, not to be cited outside either without the written consent of the Ossen holding, which everybody in the room understood to mean never.

The interval finding — the eleven seconds, the fifteen, the crystal, the spars, the dish, all of it — was not suppressed. It was retained. It was entered in full into the faculty record, circulated to the four senior people, lodged with the program, and marked as not for publication outside the faculty pending further work.

Nothing was destroyed. Nobody was censured. Ilen Vosse's document existed, and would go on existing, and anybody with the right to read it could read it forever.

And the second flight was confirmed, unanimously, on the grounds that there was no evidence of harm to any crew member and that the appropriation had been voted.

Eleven hands.

The voice that had been against her appointment six years earlier was in that room and voted, and Val knew that it was, because Belu had told her on a staircase on her first day that there had been one and had told her he would never say whose it was, and he did not, and she went out through a door past five people any one of whom might have been it.

· · ·

She walked the perimeter road afterward, all four miles, alone, in the dark.

Nobody had humiliated her. That was the thing she kept turning over. Nobody had been cruel and nobody had been stupid and the woman who had ended it had been the cleverest person in the room, and every objection had been correct, and the whole procedure had been so scrupulous that she could not find one hour of it to be angry about.

And at the end of it Sethal had kept the capability and put the warning in a drawer with a right of access.

She got back at the eleventh hour and wrote it up for Kyra in nine lines, flatly, without adjectives, because that was the only voice she had.

Then she sat for some time and added one more.

*They did not do anything wrong. That is what I cannot get past.*

*— end of chapter eleven —*

### XII. The Eleventh Series

Ilen Vosse had been telling people since he was eighteen years old that the mistake in the archive was not a mistake, and had been wrong about it for twenty-seven years, and was about to find out that he had been wrong in a very particular way.

It came out of the conversion, like everything else that year.

The final section of the eleventh series had always been the famous problem. It stopped. Not at the end of a thought — in the middle of a method, four steps into a procedure, with the fifth step referred to and not given, and then eleven pages of applications and checks that all assumed the fifth step and none of which made sense without it. Every scholar in four thousand years had read those eleven pages and concluded that the missing portion had been lost, and a school of thought held that he had taken it with him.

What nobody had been able to do was look at the numbering, because the numbering ran in his own reckoning and nobody had been able to read it.

Ilen could read it now.

· · ·

"There are no gaps," he said.

Kyra put her cup down.

"Say it in a sentence somebody could print."

"A man who loses pages leaves gaps." Ilen had the plate turned round and his own bad handwriting all over the margin. "You lose a folio, you get one-to-four and then eight-to-eleven. It is the most recognizable thing in the world and it is why the loss theory has stood for four thousand years, because everybody assumed the gap was there and nobody could read the numbers to check."

"And there isn't one."

"There is no gap anywhere in that archive. It runs clean from the first page to the last." He looked up. "He took the section out and then he renumbered the whole of the rest of it. By hand. In the same ink. Four hundred and some pages, so that the join would not show."

Kyra sat down slowly on the edge of the bench.

"That's weeks of work," she said.

"It's months."

"That's months of a man's life spent making an absence look like a whole."

"Yes," said Ilen Vosse, and his voice did something on the word. "And here is the part I have not been able to sit down for since Thirdday. The hull number is in the surviving text. The hull number of the vessel he went out in, which was grown after the renumbering, which means he did the whole of it *before he left.* He was not covering a failure. He was not editing a wreck from somewhere else. He sat in a room with four hundred pages and a pen, knowing he was going, and he removed one step and made the removal invisible, and then he went."

· · ·

They took four months proving it and it would not break.

The renumbering was in his hand and in his ink and in his reckoning. The removed section was the fifth step of the continuity method — the part that would tell you how to keep a living thing whole through a long interval — and everything downstream of it survived, complete, elegant, and useless, the way a lock survives without a key.

What he had left behind was the whole of the rest: enough for a civilization to rediscover a fold, and to build one, and to fly it, and to go a very long way in it.

And not enough to do it to a person safely, unless that civilization independently found the thing he had taken out.

"He knew what we'd do," Val said.

"He knew what anybody would do." Ilen had his chin in that position. "You give people ten solved problems and one beautiful unsolved one and they will build the beautiful one. He did not hide the eleventh series, he *advertised* it. He wanted somebody standing exactly where we are standing."

"Wanting them to get here and not get further."

"Wanting them to get here and stop and think," said Ilen, "which is not the same thing, and which is an enormous amount of faith to put in people four thousand years away who have just spent three days voting."

· · ·

He said the other thing on the way out, with his coat half on, in the doorway, and then went home.

"I was right at eighteen and I have been wrong about it ever since," he said. "I thought the mistake was a mistake somebody had made about him. It was his. He did it on purpose and I have spent twenty-seven years defending him against the wrong charge."

"Ilen," said Kyra. "You were right."

"I was right that he did something on purpose. I had it the wrong way round for twenty-seven years, and there are four people in this faculty who have been laughed at for standing next to me, and I would like to be the one who says it out loud before anybody else does."

He got as far as the stair.

"Do you know what the worst of it is?" he said. "He took out the one step that would have kept people alive and he is the only man in four thousand years who ever needed it, and he took it out anyway, and then he got into a ship."

*— end of chapter twelve —*

### XIII. You Do Not Cross Alone

Val had been carrying the sentence for three years and had not said it to anybody, which she was aware was the single most characteristic thing about her.

She said it on a Fourthday in the fifth month, on the wall, having decided in the coach on the way that she was going to and having then failed to for the first hour and ten minutes.

"I think the missing step is the Pairing," said Val.

Kyra went on looking down the orchard.

"Say something."

"I'm not going to. You've been about to say that since the lander and I have watched you not say it for three years and I am not going to put one word in front of you now."

So Val said the rest of it.

· · ·

An organism inside an interval has no reference. That was all of it, and it had taken her three years to be able to state it in one line. Every process in a Sethal body runs on timing — on eleven thousand things agreeing about what time it is — and the agreement is maintained against the outside, against light and temperature and the turning of a world. Inside the interval there is no outside. There are two, and neither of them has been decided, and a body with no reference begins, slowly and then not slowly, to disagree with itself.

Eleven seconds is how long a Sethal organism can hold the agreement on its own.

"And if there are two of you," said Kyra.

"Then you are each other's outside." Val had her hands flat on the stone. "Two bodies in resonant coupling do not need the world to tell them the time. They tell each other. Neither of them can hold the agreement alone past eleven seconds and the pair of them together does not have to, because a circuit does not need to know where it is. It only needs both ends."

Kyra put her hand in her coat and took out a notebook.

It was old and it had a cracked spine and it had been in a drawer under a shelf in a flat in Aventhal for eight years, and she turned to a page four-fifths of the way through and put it on the wall between them.

*a circuit takes two ends. V. not a finding. do not write down.*

"You told me it wasn't a finding," said Kyra Davan, "and you told me not to write it down, and I wrote it down in front of you, and you looked down the orchard and said nothing, which is the only time in twenty-five years I have ever won an argument with you by doing nothing."

Val looked at the page for a long moment.

"It still isn't a finding," she said.

"No. It's a sentence you said on the day you nearly had the whole thing and then made yourself stop."

· · ·

The evidence had been in the archive for four thousand years and it took Ilen four days to find once he knew what he was looking for.

The last four series had flown animals. Everybody had known that; it was in the fourth column and had been read as a control regime. What nobody could read, until the reckoning was converted, was a single character at the head of each run, which turned out to be a count.

Above eleven seconds, every animal flown alone came apart in the ordering.

Every animal flown as a pair did not.

Not a majority. Not a tendency. Every one, in nine runs, out to a duration Ilen refused to say out loud in the corridor and then said in a room with the door shut, which was a long way past fifteen seconds and a long way short of eleven days.

"He knew," said Kyra.

"He knew before the eleventh series existed. It's in the eighth." Ilen pressed the heels of his hands against his eyes. "He built the method on it. The fifth step is not a formula, it cannot be — it is an instruction about what you put in the vessel, and he took it out and renumbered four hundred pages so that nobody could build it without finding it first, and then he went out alone on eleven days with no pair and no reference and no possible way of surviving it by his own arithmetic."

The bench light hummed the way it did.

"Unless he found one at the other end," said Val.

· · ·

And the Vey saying, which Val could not cite, and would not be able to cite in her lifetime, sat underneath everything like a floor.

*Those who went out in it came back wrong in the reckoning, and the ones that mended were the ones that had somebody.*

Eleven days of an unclosed interval standing over a high field, and a population of farmers caught in it, and the ones who came out of it whole were the ones who had another body to be a reference for. They had not understood one word of it. They had noticed it, which is harder, and they had kept it for four thousand years by doing it rather than knowing it, in a ceremony four separate surveys had filed under pastoral sentiment.

*Two enter. Neither completes without the other. One carries what the other cannot.*

"It's not a metaphor," Val said, on the wall, to nobody in particular. "It has never been a metaphor. It is an instruction, and it is four thousand years old, and it is the fifth step."

Kyra was quiet for a while.

"Say the short version," she said. "The one that'll end up on the front of somebody's paper in two hundred years."

Val thought about it.

"You do not cross alone," she said.

*— end of chapter thirteen —*

### XIV. Evidence, Not Prophecy

The part that frightened Val was not the physics, which was somebody else's, and not the Vey, who were beyond her reach for the rest of her life. It was four sheets of paper in her own drawer.

Two women. Four regulatory markers. One man who had been fifteen seconds in an interval and had come out a small fraction of the way toward a state that eleven thousand people on a plateau are born in.

And two children, aged five, who had been born with it switched on.

· · ·

She wrote the argument out in the ninth month in the flattest language she owned, and then made Nesh read it, and then made Fesk read it, and then sat in a room while the two of them tried to break it for an afternoon and could not.

It went like this.

The Vey are coupled to their world's field by something old and structural, and it is not the four markers, because the Vey do not express the four markers. Val had proved that five years earlier and it had cost her the whole of the second half of her thirties to say out loud.

The four markers are something else. They are a state an ordinary Sethal body can enter, and two women have entered it by two entirely different roads, and a man has begun to enter it by a third, which is fifteen seconds of exposure to the thing itself.

Therefore it is not heredity. Therefore it is not destiny, and it is not a lineage, and there is no bloodline anywhere in it.

Therefore it can be acquired.

Therefore — and this was the line that Fesk read four times and then got up and walked round the room — a person could in principle be brought to it on purpose, and a person in that state, paired, might hold the agreement through an interval long enough to take a vessel somewhere no vessel has ever been.

"That's not a paper," said Fesk. "That's a program."

"I know what it is."

"Val. That is a twelve-page biology paper that ends by telling an Assembly that deep range is survivable."

"It ends by telling an Assembly that deep range is *not obviously fatal,*" Val said, "which is the weakest sentence I have ever written and the most dangerous, and I have been at it for nine months trying to find a way to write it that does not do what it is going to do."

· · ·

The children were not in the paper.

That was the one thing she would not give and did not have to: the maternal panels were hers, the samples were hers, the consent was her own and Kyra's, and there was no methodological reason to name two five-year-olds in a document about adult acquisition.

What was in the paper was two anonymous adult subjects, A and B, with acquisition by two dissimilar routes, and eleven pages of the most careful work of her life.

Anybody at Solara could work out who A and B were inside a fortnight. Four people in that building knew about the children and none of them had any reason to think about them again, and nobody else would have one for fifteen years.

"You're building a file," Kyra said, when Val showed her.

"I am building the smallest file I can."

"That's still a file, Val. That is a thing in a drawer with a number on it, and in fifteen years there will be forty people cleared to read it, and two of those forty will have taught our daughters."

"Yes."

"And we've told them nothing."

"Yes," said Val.

Neither of them said anything else about it. They had made that decision over a basket in one sentence and a half when the two of them were three weeks old, and in five years neither woman had reopened it once, and they did not reopen it now.

· · ·

The word nobody used, in any room, in any draft, for the whole of that year, was *chosen.*

Val had struck it out of a summary Nesh wrote in the seventh month and had explained why at more length than the occasion required, and Nesh — who had been writing everything down for six years — had written that down too.

*They are not special. Nothing about them is a sign. A sign is a thing that tells you about the future and this is a measurement that tells you about a mechanism, and the moment anybody in this building starts using the other word we will have stopped doing science and started doing something four thousand years older.*

It was the clearest thing she said all year, and it lasted about nine months, and then the program had a building.

*— end of chapter fourteen —*

### XV. The Program

The second flight went out of the yards in the fourth month and came back four days later with four people on it and a fault log eleven lines long, all eleven of them trivial.

Kyra watched it from the instrument floor, which was where she had watched the first one, and found that she could not make herself look at the plate for the last forty seconds and looked at Ilen's hands instead.

It went eleven times further than the first. The interval was longer and they had modelled it four different ways and been right about none of them, and the actual figure, when the clocks were reconciled, was a little over two minutes.

Two minutes and nine seconds inside a thing whose documented safe duration for a living body is eleven.

And the crew walked off the strip on their own feet, and Renn did an interview, and Senara Tevel's mother cried in front of everybody, and a physician went over all four of them for eleven days and found nothing.

Nothing again.

· · ·

"That is the worst possible outcome," said Ilen, on the coach, eleven days later, "and I want somebody to write down that I said so on the day, because in a year nobody will believe I did."

"They're alive," said Kyra.

"They are alive and I am delighted, and I will be delighted about it for the rest of my life." He had his coat over his knees. "And there are now two flights and eight people and not one thing wrong with any of them, and a document in a faculty drawer that says there is a number, and no power in this system will ever open that drawer again. We have just been given the most persuasive possible evidence for a conclusion that is not true."

"You don't know that it isn't."

"I do not know anything. That is the whole of my position and it has been for six years." Ilen looked out at the wet. "But I know what a dish does when you put it somewhere with no reference, and I know that four people have now been two minutes in a place where the front of a ship and the back of a ship kept different time, and I know that eight for eight is a number that stops arguments and does not answer questions."

· · ·

Val read Jalen Renn's second panel in the ninth month, in her own room, with the door shut and Nesh at the bench.

The four markers had moved again.

Further than the first time, and further than the first time by more than the first time had moved from nothing, which was the part she looked at for four days before she wrote anything down. A man who had been a fraction of the way was now perhaps a fifth of the way, and had done it in two minutes rather than fifteen seconds, and was perfectly well, and had eaten a very large dinner in front of eleven people at Hessen Point the week before and been funny about it.

She told him first, because she had said she would.

They sat in a corridor outside a hangar with a wind going through it and she gave him all of it, twice, and answered everything.

"So I'm changing," said Renn.

"You are changing in a way I can measure and cannot interpret, in a direction that is shared by eleven thousand people who are entirely healthy, and I do not know whether it is a wound or an adaptation and neither does anybody else."

"Will it stop?"

"I don't know."

"Will it stop if I stop going?"

"I don't know that either, and I am not going to guess in front of you."

Jalen Renn sat with his hands between his knees for a while.

"Third flight's in two years," he said. "I'd like to be on it. That's not bravery, I want to be clear, I'd just rather be the one it happens to than sit in a yard reading about it happening to Osk." He looked up. "Would you tell me not to?"

"No," Val said. "I'd tell you everything I know and let you decide, and I would find that extremely difficult, and I would do it anyway."

"Right," he said. "Then that's what we'll do."

· · ·

The program got its building in the eleventh month.

It had a name nobody used and a budget that went through the Assembly in a single afternoon, because eight people had come home in six years and one of them had done an interview, and because the woman who had written the twelve-page biology paper had used the phrase *not obviously fatal* and eleven people in a hall had read it as a green light and had been, in the narrowest possible sense, correct.

It had a hierarchy within a fortnight. It had a hall. It had, by the end of the following year, a preparation and selection effort with a countdown measured in decades and a vessel in the design stage that would not be grown for thirty years.

Hollis got the instrument argument he had lost to Kyra seven years earlier, and was gracious about it in a way that Kyra found completely disarming and complained about to four separate people.

And both women were inside it before anybody asked them whether they wanted to be. Val's paper was the second document in the file. Kyra's constant was the fourth. Neither of them had applied for anything.

· · ·

The appropriation went through an Assembly in which Vaedom Sorin sat, and had sat for twenty-six years, and Val found out afterward from a man in a corridor that her father had neither spoken for it nor against it and had been present for the whole debate.

He wrote to her in the following week. Four pages, as always, three of them about a boundary dispute in a district she had never visited.

The fourth page said that he had read her paper twice and had understood about a third of it, that he had made certain the Assembly understood he had not assisted her, and that he had also made certain that everybody in the hall knew he could have.

*You will find that the second of those is worth more to you than the first,* he wrote, *and you will dislike it, and you will be right to.*

Val put the letter in a drawer with eleven years of its predecessors and did not answer it for a month.

*— end of chapter fifteen —*

### XVI. Two Small People

On a Sixthday in the second month of the following year, with nothing whatever happening, the four of them went up to the orchard at the top of the perimeter road and spent the afternoon in it.

The girls were six. Genie had not stopped talking since the eleventh hour of the morning and had recently discovered that a question can be asked again immediately, and was working her way through the consequences of this in a systematic manner.

Kal was in a tree.

· · ·

"She's going to fall out of that."

"She isn't," said Val.

"Val, she is nine feet off the ground."

"She has been up it four times this afternoon and she has come down four times, and she has not once put her foot anywhere she had not already had her hand." Val was watching the tree with the flat attention she gave a plate. "Your daughter does not fall out of things. Your daughter works out the whole of it first and then does it, and when she cannot work it out she stands at the bottom and looks at it for eleven minutes and then does something else and does not tell anybody why."

Kyra opened her mouth, and shut it, and sat down in the grass.

"That's the most anybody has ever told me about her," she said.

"You'd have seen it yourself in a fortnight."

"No, I wouldn't," said Kyra Davan, "and you know I wouldn't, and I'm not going to pretend otherwise on a Sixthday."

· · ·

The other thing happened at about the fourth hour, and was the sort of thing that happens all the time.

Genie had got hold of the idea that she and Kal were twins. Nobody knew where it had come from — a child at the water house, or another child's mother, or one of the eleven people who had said the same thing in front of the two of them since they were a fortnight old. She had been operating on it all afternoon and had finally said it out loud, at volume, from the middle of the grass, the way she said everything.

"We're the same," Genie said.

"You're not the same."

"We ARE. Kal. Kal. We're the same, aren't we, we're—"

"You're friends," said Kyra, laughing, "which is better, and you were born on the same day in two different houses to two different mothers, so you'll have to make do."

"The same day?"

"The same day. Four hours apart, and nobody planned it, and everybody in Aventhal thought it was very funny."

Val did not say anything at all.

Kyra looked at her.

There was a silence of about the length of one breath, in an orchard, on a Sixthday, with two six-year-olds nine feet away and nothing at all happening, and both women looked at the grass, and neither said anything whatsoever, and after a moment Kyra said, "Four hours, then," and Genie said something extremely loud about the tree, and it went past.

It was the closest either of them came in eighteen years.

· · ·

Later, when the light went and they were getting two children into coats they did not want to be in, Val had Genie's arm in one hand and the coat in the other and was losing, and Kyra had Kal already done up and standing beside her being patient about it.

"Swap," said Kyra.

They swapped. Genie went into the coat in about four seconds for a woman who was shouting about a bird at the same time. Kal put her hand up into Val's without being asked, the way she had done it since she could walk.

Neither of them said anything about that either. They had both been noticing it for five years, and it had been funny for the first three, and neither of them could now have said precisely when it had stopped being funny.

*— end of chapter sixteen —*

### XVII. Nearly Identical

Kyra went back to her own plateau data in the seventh month, for the dullest possible reason, which was that somebody had to write the appendix.

The object under the byre was now a known source. She had measured it at eleven inches with an instrument that would have looked like a religious artifact to the girl who had rebuilt a housing in a shed on that plateau, and she had a model of its field that was good to nine places and had been checked by four people.

So the appendix was arithmetic. Take the model. Propagate it out four miles across a valley, through rock and weather and altitude, to the four points where a stubborn nineteen-year-old had stood with a broken instrument for two years. Subtract.

What should be left is nothing.

It took her eleven days to do it properly and she did it twice, and the second time she had Rieve do the propagation independently without telling her what it was for.

What was left was not nothing.

· · ·

It was very small. It was smaller than the thing she had spent her life being known for; it sat a long way below the number that had made her Account and her name, and she would never have seen it at nineteen, and nobody with instruments built before she was forty could have seen it at all.

It was not noise.

She had spent the whole of her working life learning the difference, on that plateau and at the observatory and in a cold room at Solara at the eleventh hour of the evening. Noise has a character. It changes when the instrument changes. It is not there in the morning in the same shape it was there at night.

This was there in the morning in the same shape.

And it was there at all four points, and it was there in the four sets she had taken with the rebuilt housing and the four she had taken with the original before she broke it down, and it was there in the modern set she had taken with Ilen's magnetometer standing eleven inches from four thousand years of a dead man's hull.

The same residual. Every time. Under everything.

· · ·

She sat on the floor of the instrument hall with her back against the bench leg, which she had done before, in that room, seven years earlier, at the eleventh hour of the evening, with the rain going across the fields outside.

Then she went and got Val out of a meeting.

"You can't come in here."

"I've come in here," said Kyra. "Sorry. Four minutes."

She put the sheet on the table in front of eleven people and did not explain it to any of them.

Val looked at it for about nine seconds.

"Where's the source?"

"Not under the byre."

"Kyra—"

"It isn't the object. I have modelled the object to nine places and subtracted it and this is what is left, and it is not the object, and it is not Thennet, and I have been sitting on the floor for an hour working out how to say the next part in a way that does not sound like a woman who has had a very long career."

"Say it badly."

"It isn't in this system," said Kyra Davan.

*— end of chapter seventeen —*

### XVIII. Every Eleven Years

It took four months and it was the easiest work any of them did in six years, because for once in their lives they knew exactly what they were looking for.

A residual with a fixed signature and no local source has a direction. Kyra had four points on a plateau and one under a byre and eleven of Ilen's modern stations, and by the end of the second month she had an arc, and by the end of the third she had something that was not in this system and was not close to it.

And then Ilen went into the archives, which is to say all of them.

Field measurements are the dullest data anybody takes. They are taken continuously, by everybody, for a hundred years, by people characterizing something else entirely, and they are stored because storing them is cheaper than deciding what to throw away. Nobody reads them. There is no reason to read them.

It was in all of them.

· · ·

It was in Sethal's own magnetic record, under a century of weather, at the level of the eleventh decimal place.

It was on Thennet, obviously, which is where it had ruined a nineteen-year-old's life.

It was in the two survey series from the outer bodies, where it had been logged as instrument drift by four separate people across sixty years, one of whom had written a very cross note about it that Ilen had framed.

It was in the station record from the yards, which went back forty years and was the most carefully kept data in the system, and in which it was plainly visible the moment you knew to subtract everything else.

And it was periodic.

It sat at a level nobody would ever notice, and then for a span of some weeks it strengthened — not much, perhaps a fifth — and then it sank back, and it did this with a regularity you could set an institute by.

Every eleven years.

· · ·

"That's not a coincidence," said Kyra.

"It is very probably a coincidence," Ilen said, "and I am going to go on saying that for as long as I can, and you should watch how long I manage."

"Ilen, everything about this is elevens. His reckoning runs in elevens. The safe interval is eleven seconds. The sky stood in two places for eleven days—"

"And there are eleven thousand Vey and eleven buildings at Solara and I have eleven pens," said Ilen Vosse. "Kyra. I want it too. I want it so much I can taste it and that is exactly why I am not having it. Write down that the period is eleven years and let somebody in ninety years tell us what that means."

· · ·

The last of it was Val's, and she found it by reading, because by then she had learned to read the fourth column as well as anybody alive except one man.

Sorren Dael had taken field measurements. Of course he had; he had taken every measurement there was, for forty years, in eleven places, and none of it had ever meant anything to anybody because the reckoning could not be converted.

It converted now.

He had it. Four thousand years ago, on a world with no fold and no yards and no instrument better than something a village smith could have made, a man had sat down and written a column of numbers that had a residual in it with a fixed signature and a period of eleven years, and had gone on writing it for four decades, and had never once said what he thought it was.

The phase was continuous with Kyra's.

"It's the same signal," Val said.

"It's the same signal."

"Four thousand years, and it has not moved, and it has not changed, and it has not stopped."

· · ·

They sat with it, the three of them, in a room at Solara at the eleventh hour of the evening, with nobody else in the building.

"He wasn't looking for a fold," Ilen said, at last. "That's the thing I have been trying not to say for a week. He was forty years old and he had solved distance ten times and he was measuring a field that nobody else could see, and then he built a method that opens an interval, and I have always assumed those were two separate careers."

"They weren't."

"No. He found it first." Ilen leaned on the table with his arms straight. "He found something in the field of his own world that was periodic and had no source, and he spent the rest of his life working out what could make it, and what he built was not an invention. It was an *answer.* He built a thing that would do what the signal does, in order to find out what the signal is."

Neither of them answered him.

"He didn't invent the fold," said Val.

"No."

"He found a structure that was already there, and worked out how to use it, and then removed the one step that would have let anybody else use it safely, and went out into it alone to see who was at the other end."

The building made the noises a building makes.

"And it's periodic," Kyra said.

"Yes."

"Ilen. A thing that is used every eleven years is not a structure. It's a *timetable.*"

Ilen Vosse did not answer her. He sat in a room with two women he had known since he was eighteen years old, on a wet evening in the eleventh month, with six years of it on the table in front of them at last, and he looked at the window for a long time.

"It was always in the data," he said. "That's the part I cannot get past. Every world, every station, a hundred years of it, and Dael's forty before that, and not one of us ever had a reason to look."

*— end of book six —*

## Part Two — Detailed Summary

### Premise

*The Wake* begins in the silence after Ilen Vosse reads eleven marks on a four-thousand-year-old hull fragment and says it belongs to Sorren Dael. What follows is six years of work in which three scientists establish what a fold actually is, what Dael was actually doing, and why the thing that killed him did not kill the four people who flew the first one — and then watch a scrupulous, intelligent, entirely well-meaning institution file the answer in a drawer.

It is the book in which the series' physics arrives. Distance turns out to be free; **duration** is the variable; and the Vey ceremony that four separate anthropological surveys filed under pastoral sentiment turns out to be an engineering instruction four thousand years old.

### Principal characters

- **Val Sorin** — forty-one, running the biology group at Solara, holding the return-hull characterization and two sets of maternal panels nobody else has reason to look at.
- **Kyra Davan** — whose unsourced constant has been in the literature with her surname on it for sixteen years, and whose whole professional life has been the difference between two numbers.
- **Ilen Vosse** — forty-three, running the drive faculty, in the best year of his professional life and visibly paying for it; the only man alive who can read a dead man's private reckoning.
- **Marenne Vey** — who comes down to Sethal for the first time in living memory to say one thing in a room with three people in it.
- **Narra Vey** — ninety-one, who asked which cup, and who does not have the nights to spare.
- **Jalen Renn** — thirty-four, commander of the first crewed fold, who has already got the only thing he ever wanted and who has never been asked anything in his life.
- **Toven Belu** — who will not stop her and wants that on the record.
- **Genie** and **Kal** — four, then five, then six.

### Chapter-by-chapter

**I. Isotopes** — Ilen asks the room for a week and is given six days by the only person who can grant them. Kyra writes to Marenne that night in the appalling building, at a table she ate at when she was nineteen, with a heating system ticking below her in exactly the rhythm it had twenty-one years earlier. In their lives the two women have exchanged four letters, about instruments and a daughter and a knee that does not work in cold weather, and not one of them has contained the word Sorin — never an agreement, simply the shape the thing took, the way a path becomes the shape of a field. The letter says that the man downstairs is the best instrument anybody on Sethal ever built out of a person, that he has been right about a dead man since he was eighteen and laughed at for twenty-four years, that he will not touch the object or photograph it or do anything Ossen forbids, and that Val has nothing left to spend and knows it. And a last line she looks at for some time before letting it stand: that she is asking on her own account and not on Val's, and that Marenne knows what it costs her to say so. The answer comes at the fourth hour by way of a boy of fourteen who has been made to walk up the road and does not know why: six days, and the woman who wrote may sit in the room, and the other one may not. The boy asks which of them is the one who took things. *Not me*, says Kyra, and gives him a coin he did not ask for, and goes and wakes Val and tells her the first half. Val learns the second half on the third day from Ilen, who assumed everybody knew. She says nothing about it at all, spends the six days on the surface walking the valley with a field kit she is not using, comes back each evening and asks four questions and listens to the answers, and never once asks what the room is like. What the six days produce: the object is closed-cell lattice, grown rather than cast, cell walls a third thinner than anything the yards have managed in eleven years of trying, broken off something larger along a line that is not a fracture in the ordinary sense — the material did not shatter, it *stopped*, the way a poured thing stops. The vitrification ran in one direction and set, and Ilen will not say what would do that: he sits on the stones on the fourth day, looks at the run of it for an hour, and says he would rather be wrong in eleven years than stupid in front of two women that night. Four thousand years, plus or minus a century and a half. And eleven marks in the unmelted band that are a hull number and a date in a reckoning one man invented and told nobody, which Ilen reads the way a person reads their own handwriting, crying twice and apologizing both times. Then, on the last evening, Kyra asks the question that has been sitting in her since the first hour: where is the rest of it? That is a door's worth of a hull, and you do not lose the rest of a hull. And nothing has ever been dug up on that plateau — no crater, no scatter, no burn layer, no metal, no second piece, not one fragment in four thousand years of people turning the same eleven fields over by hand. If there were a ship there they would have found it with a plough. So where is it? *Somewhere else.* He has a shape in his head that accounts for a four-thousand-year-old hull made better than they can make it, a man who took that hull out and arrived nowhere anybody has ever looked, and no wreck — and he would sound like a lunatic saying it in a cellar, so he will go home and do the arithmetic first. Two months. It takes him three.

**II. Eleven Days** — On the fifth of the six days a woman of about ninety comes down the track to find Val standing in a field doing nothing with a field kit. Val knows her at once, which surprises her: she saw the face for four hours in a stone hall, at the back, near the door, and it asked her which cup. Narra Vey sits down on a wall with the care of a person who has calculated the whole descent in advance, tells Val to sit because she is too tall standing, and says she had thought of that question in the night and was pleased with it. They have the piece out of the ground — not asking, telling. Does Val know what the Vey say about it? Nobody has told them anything. No; nobody would. And it is not a secret, she is careful to say: not hidden, not holy, no ceremony around it, and the house above it is a byre. Any child on the plateau could have given them the same eleven words. Then why has nobody— *Because nobody asked us, and because the last people who came here and were interested in us took things out of our arms in a shed and did not say what for.* Val does not look away. *That was me.* Narra knows; she was in the hall. And she makes a small impatient movement: Val stood on a floor for four hours and answered a girl of sixteen better than she answered the men, and Narra has been thinking about it every night since, and she is ninety-one and does not have the nights to spare. The saying, which Val writes down twice that evening — once from memory and once again the next morning to see whether the two agree, and they agree to four words — is that for eleven days the sky stood in two places; the high field was two fields; a woman went out to the animals in the morning and came back in the morning; those who went out in it came back wrong in the reckoning, and the ones that mended were the ones that had somebody; and on the eleventh day the sky closed and there was a new thing in the ground. That is the whole of it; there is a version with more in it but it is later and somebody has made it nicer. Asked what any of it means, Narra answers with the flat patience of a woman explaining weather to a child from the city: it means the sky stood in two places, nobody there has ever thought it meant anything else, and it is Val's lot who need it to be a story about something. Val goes through it eleven times that night and four more on the lander. *Came back in the morning* — not the following morning, the same one: a sentence carried for four thousand years by people who would have dropped it in a generation if it had not been strange enough to keep. *Came back wrong in the reckoning* — wrong in the counting, wrong in the numbering, which she sits with for an hour in a dark cabin with everybody else asleep. And then the line she does not write down on the first night and does write down on the second and then sits looking at: that the ones who mended were the ones who had somebody. She has heard a version of that before; everybody on two worlds has. It is in a ceremony eleven thousand people perform, it was quoted at her in a common room at nineteen by a woman who thought it was charming, and it has been printed in four anthropological surveys as an example of pastoral sentiment — two enter, neither completes without the other, one carries what the other cannot. Val does not write the next line, because she can hear exactly how it would sound in a room, and because she has spent eighteen years learning what happens to a woman who says an enormous thing before she can prove it. She turns the page and writes, in the flattest language she owns, a question to ask Ilen: whether an interval has a duration that can be reported by the people inside it.

**III. Two Endpoints** — Ilen takes three months and then calls nine people into a room and shuts the door, which he has never done in his life: four from the drive faculty who have been doing his arithmetic and have come out of it looking hunted, Kyra, Val, a woman from the yards who has built more hull than anybody alive, and Hollis down from Solara in the wet without being told why. He is going to say four things and three of them will sound stupid. The first is the fifteen seconds, which everybody has known about for three years and has stopped thinking about the way you stop thinking about a noise in a house. The second is that a fold has two parts — not two stages, two parts running at once: the part that moves position, which forty years of work has described to eleven places, and a second part nobody has ever had to name because in an ordinary fold it lasts for a length of time too small to have a unit. Call it the interval; somebody will call it something better later and he will be delighted. The third is what happens inside it, which he puts up badly with his own handwriting crawling round the edges and talks about for forty minutes, at the end of which the woman from the yards says he is telling her the ship does not have an address. Yes. For fifteen seconds their ship was not anywhere — no, and that is the bit everybody gets wrong and he has been getting wrong for a year: it is not nowhere, it is *both*. It has a departure and an arrival and for the length of the interval it has not been decided which of them it belongs to. The instruments were not malfunctioning; they were reporting two true things. One star tracker on the home sky and one on the far sky — and a third on a sky that is not in the catalogue, which he cannot account for and is not going to try to in front of nine people. The fourth thing takes him four minutes and empties the room afterward: Sorren Dael went out with an interval of eleven days. That is what the eleventh series *is* — not a longer fold but a fold with the interval opened up, which is the only way anybody has ever got past the range limit, and why the method looks insane if you read it as an extension of the first ten, which is how he read it for twenty-four years and how everybody has read it for four thousand. It is in the notation twice and he read it as a duration of transit both times. *For eleven days the sky stood in two places*, says Val, and everyone turns round. It is a Vey saying, four thousand years old, with a version a child on that plateau could give you, describing a high field that was two fields and a woman who went out in the morning and came back in the morning and a new thing in the ground on the eleventh day. Hollis calls it a farming story. It is an observation, Val says — an entirely accurate observation made by people with no vocabulary at all, which has been sitting in the anthropological record for a hundred years under *pastoral idiom*, and the reason nobody has ever put it against a fold notation is that nobody has ever had both on the same table. And then it is Kyra, whose whole professional life has been the difference between two numbers, who says the last of it: then there are two endpoints. Ilen turns round very slowly. He keeps saying *the ship*, and it is not a ship, it is a hull full of separate objects in a bag — so what if the bag does not have to come out in one place? There is no wreck on Thennet: no crater, no scatter, no burn, nothing in four thousand years of ploughing, and a door-sized piece of his hull under a byre with his hand on it. And there is no Sorren Dael — not at the solution, not anywhere, four thousand years and not so much as a signal. She is not asserting it; she is asking somebody in that room with better arithmetic than hers to tell her it is not possible. Nobody does. Ilen sits down on the edge of the table in front of nine people and looks at the far wall for the better part of a minute, and says: it put him somewhere, which is different. He said that at nineteen, to two students, on a night when he had been given a basement and a dead man's papers — and Val remembers the whole room it was said in, and the fact that nobody else present knows what they have just heard makes her want, for the first time in years, to go and sit somewhere alone.

**IV. The Line That Left** — Marenne comes down to Sethal in the first month, which no member of the Ossen holding has done in the memory of anybody living, including her own. The institute does not know what to do with her and does it badly: an offer of the long room and a lunch, declined; a proposal relayed by a man who has never met her that she might address an Assembly committee, unanswered; and a physician sent out to see whether the altitude difference is troubling her, who comes back reporting that he was shown the door in four words. What she wants is a room with three people in it. They give her Val's office, the only room at the institute without a committee attached, and she sits with her back to the window and does not take her coat off. She will say it and then go: she has spent nine months deciding to and is not going to spend the afternoon on it as well. They will want to write it down and she would rather they didn't yet — Ilen especially, who turns out his coat, which has eleven things in it, all of them pens, and something happens to Marenne Vey's mouth that is very nearly a smile and does not arrive. Four thousand years of no one in and no one out is true, and is the first line of every survey ever written about them, and it is true with one exception — and the exception is not a secret, it is an *agreement*. A family left: eleven of them, or nine, depending on who tells it, and not four thousand years ago but eight generations back, and it is in the names, and she can give the names. Why did they go? Because they could feel it. Which is not a figure of speech, and she wants to be careful, because they will make it into one: there are people born on that plateau every generation or so who know where the piece under the byre is without being told — not by the house, not by the ground. They can stand in a field in the dark and turn round and point at it. It frightens people when they are small and is a nuisance to everybody including them when they are grown, and there has never been a single thing anybody could do about it. They asked to go. There was a discussion that lasted a long time, and at the end the holding agreed they should, and agreed to the other thing as well, which was that the Vey would stop saying them. Not erase — they do not erase. They simply stopped putting them in the names. Everyone agreed, including the family, and it was done out of kindness in both directions, and it means Marenne is the first person in eight generations to say any of this to anybody who is not Vey. What did it cost her to come? *That's my business.* They have the rest inside the hour, and it is Kyra who puts the last piece on the table out of a notebook, from a conversation with a registry clerk four years earlier: two people asked after Alexander Muler at the west desk before he went, neither from the institute, neither of them women, and nobody kept a book on it. That is how he knew. Somebody found him and told him what he was. He is from that line — five or six generations off the plateau, in a city, with a name that is not a Vey name, working in materials and going quietly grey and being very good at getting people to like him — and one day two men he had never met knocked on his door. He put three figures in the back of a notebook: Thennet, the Dael archive, and a solution nobody has ever seen anything at. He was not hiding from anybody. He was *looking*, and he came to a fold institute because that is where you would go. And there is no medical record and there never was one, and they spent four months proving nobody did it on purpose. The last of it is the part they do not get. He left Sethal, which is findable and which they find in eleven days: a passage worked for on a supply hauler out of Hessen Point in the eleventh month four years before, with his own name on the manifest and no attempt at anything else, and an ordinary crossing to an ordinary place four days out. After that, nothing — not a death, not a disappearance nor a hint of one, no report, no claim, no file. A man walked off a hauler at a working port and went about his business and the paper stops, the way paper stops about most people who are not important, and they turn that port over for four months and find a room he rented for eleven weeks and paid up and left clean. He is alive somewhere, Kyra says at the end of the four months. He is a man of thirty-eight who is very good at being liked, Val answers: he could be four hundred years old in a town nobody has heard of, and they could spend the rest of their lives on it, and they would be doing it because it is easier than the other work. *That's not a reason to stop.* *No. It's a reason to know why we're going.* They stop. It takes Kyra a fortnight to agree to it and she never entirely does, and neither of them ever says out loud that there are two other people who are going to want that answer one day and are three.

**V. Distance Is Not the Variable** — What the eleven marks actually give them is a date, and what the date gives them is the key to a filing system. Dael kept his own reckoning, beginning at something nobody could identify and running in elevens, which four generations of scholars treated as an eccentricity and converted out of where they could and shrugged at where they could not. The hull number has a date beside it in that reckoning and the object has an isotopic age, and between them Ilen has, for the first time in four thousand years, one fixed point. A fortnight to convert the whole archive. Then he stops talking to anybody for a week and sends Kyra a message consisting of one line: the series is not eleven attempts at one thing. It is ten solved problems and one unsolved one, and once the dates are right you can see him doing it, year by year, in order, like a man going up a staircase in the dark. The first ten are distance — all of them, every one an increase in range, every one flown by him in the little vessels the yards had turned out for nine hundred years, and the last of the ten put a man four times further out than Sethal would manage again until the century Kyra was born in. And underneath all ten, from the fourth onward, a second set of numbers nobody could ever make sense of because nobody ever had the dates. They are durations, in seconds. He was measuring the interval from the fourth series — forty years before he ever tried to open one — and he was frightened of it. The fourth column is what he put in the interval. Not instruments: he had instruments and used them and they told him nothing, because an instrument inside an interval is a thing with two true readings and no opinion about either. So he stopped asking instruments and started asking the only thing that has an opinion. He flew living material — seed stock and gut cultures and, in the last four series, small animals — at intervals he could set, and wrote down what came back, for thirty years. Below eleven seconds, everything came back. Not unchanged, and he was scrupulous about that: a column of small oddities runs all the way down, things a shade out, things a fraction early, a set of cultures at nine seconds that did something he described in a word nobody can now translate. But everything came back and went on living, and the oddities did not compound. Above eleven seconds the column changes. He does not use a word like *dead*; he uses a phrase, four times, which converts to something very close to *came apart in the ordering*. The shape of it, as Kyra puts it on the wall: distance is free. It costs energy and money and it does not cost you anything that matters, because the position part is the part he solved ten times. Duration is everything — the longer a thing is inside the interval, the more chances its state has to come back together in the wrong order. Matter hardly notices, because matter is not doing anything; a rock is a rock in either endpoint. A living body is not a thing, it is a process: eleven thousand processes that have to stay in step with each other, every one of which has to agree about what time it is. And on Sethal, Val says, they are worse than most things, because what their cells do at the bottom *is* timing — resonance, coordination, the one system in the known universe you could describe without stretching anything as an agreement about what time it is. So he was not trying to go further. The eleventh series is not distance at all. The first ten were how to move a man; the eleventh is how to keep him.

**VI. Eleven** — They put it in front of Ilen in his own room, because Kyra says it is not a thing to do on a link and Val agrees before she has finished the sentence. He is forty-three and thinner than he was and in the best year of his professional life, with a chart of the fourth column behind him that he drew himself, badly, and he is delighted to see them — and he has known for eleven days, and has been waiting for somebody else to say it, because he has not been able to make himself write it down. Val puts the sheet down anyway: eleven seconds, in Dael's hand, converted and checked twice, the last safe interval he ever recorded for living material. And underneath it the number everybody on the planet celebrated for four years, that was in the Assembly's own statement and on the front of the news sheets and in a song somebody at the yards wrote that was funny for about a month. Fifteen. Ilen looks at the two numbers for a long time, and then does the thing nobody in the room has ever seen him do, which is to sit down slowly and completely and put both hands flat on his knees and stop. There were four people on it. He names them: Jalen Renn, Lira Osk, Torrin Marr, Senara Tevel. He taught all four. Osk was in his second-year class and slept through eleven weeks of it and got the highest mark he has ever given anybody; Marr's wife makes a thing with fish in it that he has eaten at their table nine times. He put the proposal up four times, and the fourth time he stood in the long room at Solara and told a committee that a crewed flight was the only honest test, because an empty hull tells you what happened to a hull — and that is a quotation, and he can give the day. They walked out of it, and there is a physician's report nine days long with nothing in it, nothing whatever. That is true and it stays true, Val says. He knows it stays true; he is telling her what he has in his head, which is four people being examined for nine days by a man looking for a thing he had no name for. Then Kyra says the hard thing, because Kyra always says the hard thing: it might be nothing. Dael's eleven seconds is a limit for what he flew, and what he flew was seed stock and gut cultures and four animals in a box, and none of them is a person and none of them was inside a hull with a field round it. You could line up eleven reasons why fifteen seconds in one of their vessels is not the same fifteen seconds and four of them would be good. And the fifth? The fifth is that a man who spent thirty years measuring one number wrote it down and drew a line under it, and they went four seconds past it with four people inside and did not know they had done it until three years afterward. Then Ilen goes to the window and says the other thing — the one he has been not saying for eleven days, and he would like them to notice that he is saying it now, in a room, to two people who can make it his problem. The second flight is scheduled: the appropriation went through at the turn and the hull has been growing since before they went to Thennet. It goes further, which is the whole point of it and does not frighten him at all. And the interval will be longer — they do not know how much longer and have never had a reason to care, because until eleven days ago the interval was a thing that lasted no time and did nothing, and all of them have been standing on it for four years calling it a discrepancy. When? Fourteen months.

**VII. The Four Who Walked Out** — Val's group has held return-hull characterization from the beginning, because four years earlier Ilen said in a room that if that thing came back with anything living on it that had not gone out on it he wanted a biologist saying so and not a committee. It is unglamorous work and her twelve have been at it three years: swabs off surfaces, the water plant, the air, and four sealed sample racks that went up as an afterthought and have turned out to be the most interesting objects in the system. All of that is hers. The crew is not. Four people were assayed before and after, at length, by a programme physician, and those panels sit in a medical registry with a door on it, and Vaelith Sorin has no more right to them than to anybody else's. She could apply; there is a form and a committee and a schedule, and Nesh works out the timings in an afternoon and comes back with four months at the optimistic end. The second flight is in fourteen. So she goes up to Hessen Point and finds Jalen Renn in a yard behind the strip in the rain, arguing with a loadmaster about a mass budget, and stands at a distance until he is finished, which takes a while and which she enjoys more than she expected to. He is thirty-four, a head shorter than her, built like a man who does not stop moving, with the specific happiness of somebody who has already got the only thing he wanted. He knows who she is — the hull one — and wants a fifth attempt at understanding the thing on the dish, Vosse having explained it to him four times unsuccessfully. She tells him she is there to ask him for something, that she wants to do it properly, and that she would rather he let her say the whole of it before answering. He puts his hands in his pockets and stands in the rain and lets her get to the end. She tells him about the interval, and eleven and fifteen, and that nothing has happened to him or the other three, and that the physician looked for nine days and found nothing, and that she has no reason to believe anything is wrong with any of them and is not suggesting there is. And then that she wants his panels, before and after, and has no right to them; that the proper route would take four months and the flight is in fourteen; and that if he says yes she will be looking at his body without an institute behind her, and he should understand exactly what that means for him and for her. What is she looking for? *I don't know.* He says that is an honest answer and he is not complaining about it. Anything that moved — and if something moved she will not be able to tell him what it means, possibly for years, and it will be on a sheet with his name on it in a building he does not work in. Renn thinks about it for about four seconds and says yes, obviously yes, have the lot. Two things first, though. There are three other people and she will have to ask them herself, and Tevel will say yes and Marr will want his wife in the room and Osk will make her work for it and then say yes. And the second is that he is going again in fourteen months, and whatever she finds, he would like to know before he goes — not so he can decide, because he has decided, but so that it is him that knows it and not a committee. Then he goes back to the loadmaster. And Val stands in a wet yard with her hands at her sides, aware that she has just done, at forty-one, in four minutes, in the rain, the thing she did not do at twenty-two in a shed on a plateau with nineteen people's tissue in her bag. It had not been difficult. That is the part she takes home with her. She tells Belu the same evening, standing up, before he can ask. He says she should have come to him first; she says he would have said no. He would have said no and would have been right, and then would have spent four months getting her a yes. The flight is in fourteen. Belu takes his glasses off, which is what he does instead of raising his voice, and says he is not going to stop her — and wants that on the record between them, because in about a year somebody is going to ask him whether he knew, and he is going to say that he knew on the day and did not stop it. And the same person will ask whether the consent was obtained by the head of a group at that institute, in a yard, in the rain, with nobody present, and he will have to say yes to that as well. Do the work, he tells her, and write down every single thing you do while you do it, because one of these days that is going to be all you have. Marr wants his wife in the room. Tevel says yes on the link inside a minute. Osk asks eleven questions, four of which Val cannot answer, takes a fortnight, and then sends a note saying fine, but she wants a copy of everything, including the parts Val thinks she will not understand. Nesh stands at the bench and writes down every step. It takes nine days, and on the seventh Val stops and sits back and says nothing for so long that Nesh puts her pen down. In three of the four, nothing — four panels' worth of a tediously healthy adult. In Jalen Renn, four regulatory markers have moved. Not far, and not into the range she has spent three years looking at in her own daughter and in Kal: a fraction of the way, in exactly the direction she would have drawn if somebody had handed her a pencil and asked what the beginning of it would look like, by a margin small enough that a careful person could call it drift and sleep perfectly well. Is that a finding? It is one man, once, by a margin she would not accept from Nesh. And then she takes the sheet to the window and stands with it a while: and it is a man who had never been within four hours of Thennet in his life, who spent fifteen seconds somewhere, and came out of it a small distance closer to eleven thousand people on a plateau.

**VIII. What Came Back** — The rest of the manifest has been in four crates in a cold room for three years, and the reason nobody looked at it properly is that everybody had already looked and found nothing wrong. They go back through all four in the eighth month, with the dates converted and the interval on the table and four people's assays in a locked drawer — and this time they are not looking for damage. They are looking for things that kept the wrong time. A timing crystal out of the secondary reference has a defect density belonging to a component about nine years old; it was grown eleven months before the flight and logged on return as within tolerance, because it was within tolerance, because the tolerance on a crystal of that class is enormous and nobody had ever had any reason to ask a crystal how old it felt. A strip of hull plating off the forward spar has aged — not much, a fraction, at the limit of what Kyra can resolve, and she resolves it four times and then has it done by somebody who does not know why. And a second strip, off the aft spar, eleven feet away, has aged by a slightly smaller fraction. That is the worst one. If the whole ship had come back four months old, that is a story — a strange story, and one thing happening to one object. This is one *ship* in which the front and the back did not have the same amount of time happen to them. And then the sample racks, which are Val's, and which she has been putting off. There are four and they went up as afterthoughts, the way a rack of environmental monitors always does, and three of them are dull. The fourth has a culture dish in it. It is not an experiment; nobody designed it; it is a control — a standard reference culture, the most boring organism anybody at Solara has, put aboard so that if the air plant did something interesting on the way there would be a baseline to compare it against. Val counts the generations three times before she lets Nesh see it. The dish was out of the incubator, aboard the hull, for four minutes and eleven seconds. Most of what was in it lived four minutes and eleven seconds. A patch of it — a fraction of a percent, not localized to any one place — went through something in the region of sixty generations. Another part did perhaps a dozen. And in one corner there is a population that did nothing whatever: not a division, not a shift, less than four minutes' worth of anything, as though it had been set down and picked up again. Sixty generations of that organism is a fortnight. *Fourteen days.* *In four minutes.* In fifteen seconds, Val says — and that is the part to hold on to, because the four minutes were ordinary and the fifteen were not. They put it in front of Ilen on the Fourthday and he goes very quiet, and then asks the question neither of them has been able to ask aloud for a week: not uniform. No. Not a gradient either — not front-to-back, not warm-to-cold, not near-the-wall and far-from-it. Val has looked for eleven kinds of gradient and it is not any of them. It is not *anywhere*: it is a dish, and time did not happen to it evenly, and she can put her finger on the glass and say that here it was a fortnight and eleven millimetres away it was nothing at all. So it is not that the interval is long. It is that inside the interval, duration is not a property of the ship — it is a property of every separate piece of what is in it. Ilen puts both hands over his mouth: that is horrible. That is not a hazard and not a dose; you cannot shield anybody from that; there is no such thing as a safe duration for a body if the body does not have one duration. There is one, says Kyra from the end of the bench, where she has been quiet for some minutes. There is eleven seconds. It held for thirty years of a dead man's animals and it held for four people three years ago and it will hold for four more in eight months, and nobody has the faintest idea why — and that is now the only question in the world.

**IX. Ilen Vosse Will Not Have It Buried** — The drive faculty's position is not cowardice, and that is what makes it difficult for four months. Four people went out and came back and walked off the strip on their own feet; a physician went over all four for nine days and found nothing; three years later they are all still working and one of them is arguing with a loadmaster every Thirdday. There is, at this moment, nothing whatever to warn anybody about. What there is instead is a strange old number out of a converted archive, a crystal that felt nine, two bits of hull that disagree by a fraction, a dish nobody designed, and one man's regulatory markers a small distance out of a range that nobody but Vaelith Sorin ever had a reason to look at — obtained, it will eventually be noticed, in a yard. Put that in front of the Assembly and you do not get caution: you get forty years of work stopped by eleven people who have not understood a word of it, and a hull rotting at the yards, and a generation of the best minds on the planet going into orbital mechanics because the fold is finished. Nobody says *bury it*. What they say is *not yet*, which is the same sentence with better manners, and four senior people are saying it who have given their lives to this and are not fools. Ilen lets them say it for four months. He does not sulk and does not campaign and does not leak anything to anybody, and goes on running the faculty and losing two arguments a week to people he trained, and on the whole it is the happiest year he has ever had, which several people afterward find difficult to forgive. Then he writes it up. Sixty pages: the conversion of the archive, the fourth column, the eleven seconds, the fifteen, the crystal, the two spars, the dish, and — in four lines of description with no name — one crewman's shifted markers. It contains no recommendation of any kind, which is the most aggressive thing a document of that sort can do. And there is one name at the top of it. Val tells him to take hers off. It is off; it was never on. Half of that is her group's — half of it is her group's and all of it is the faculty's and the name on the front is his, and he would like her to think for a moment about which of the two of them can afford it. She has a finding on her record; he has a fold. They cannot do anything to him that he will notice. They can end her in an afternoon and half of them would enjoy it, and he watched that happen to her once already when he was twenty-two and did nothing, so if she does not mind, he will have the name. He does not put it through a friend. He puts it through the faculty, up the proper stair, at the proper meeting, with the four senior people in the room who have been saying *not yet* since the spring, and reads the four paragraphs at the front aloud himself because one of them asks him to and he cannot see a reason not to. Afterward one of the four — a man of seventy who taught him — stays behind to tell him he has just finished his own career for a rounding error. *Possibly.* He could have waited a year: one year, and he would have had the second flight, and if it came back clean— If it comes back clean, Ilen says, he will have sat on this for a year and been lucky, and he does not want to have been lucky. He wants to have been a man who wrote it down when he knew it, and he would like to go on being that afterward, and he is fifty in six years and has not got the constitution to be anything else. He goes home on the coach and sleeps eleven hours, which for him is a holiday. The document does one thing before anybody votes on anything, quietly, and it is the only win anybody gets that year: the second flight moves. Not because of a decision and not in the minutes of any meeting — the hull needs four more months of growing, and then the yards find a scheduling difficulty, and then the appropriation's second tranche comes late, and by the end of it the date has gone back by two years. Nobody announces a deferral because nobody has deferred anything: four senior people who spent four months saying *not yet* read sixty pages and went away and did what senior people do, which is nothing that can be pointed at. Will they use it? Somebody will, says Ilen Vosse. It won't be a committee.

**X. Say It or Manage It** — They have the worst argument of their lives on a Fourthday in the grass below the water house with two children eleven feet away, and have to conduct it in undertones. The girls are four: Genie has found a stick and is explaining it, and Kal has found a different stick and has no intention of explaining anything, and is watching a bird with the total attention of somebody who intends to do something about it later. He has put it up, Kyra says; it has gone up the stair; that is the end of the argument, it exists now. It exists inside a faculty, Val says — and a document inside a faculty is a document, while a document in front of the Assembly is a decision, and they are not ready to have the decision made for them by eleven people in a hall. She wants another year. They fly in two years. She knows when they fly. Then say what you actually want, Kyra says, because from here it sounds like the woman who has been managing the truth since she was eighteen has found one more reason. Genie comes over with the stick, and there is an interval of about ninety seconds in which two women who have just said unforgivable things to each other admire a stick, and Kal comes and stands against Val's knee and leans, and Val puts her hand on the back of the child's head without appearing to notice she has done it. Then the two of them go off toward the trees and it starts again. It is Renn. He said yes to *her*, in a yard, in the rain, on four seconds' thought, because he is that sort of man — and he said yes to a biologist looking at his panels. He did not say yes to his name going in front of the Assembly, and there is no version of this that goes public in which he is not named, because there were four of them, and one of them was the commander, and any child on the planet can count. Ilen took the name out — Ilen took the name off a sheet; there were four people on that hull, it is the most famous crew in four thousand years, and every one of them has been photographed. Within a fortnight of that document leaving the faculty everybody on Sethal will know that one of four people has something wrong with him, and the four will be asked at their own doors which one, and Renn will say it was him, because he will think that is the decent thing. Kyra opens her mouth and shuts it again. Then ask him. *I intend to.* No — that is the answer, Kyra says: that is the whole answer. It is not hers to weigh. She has been sitting on this for a month doing arithmetic about a man's life on his behalf. *I am aware of what I have been doing.* And then the sentence they both remember: *you did this to me.* Val goes still. In a room on the ground floor of the east range with a form and a man called Oren, twenty years ago, she decided what Kyra could carry and did not ask her, and she was right, and it cost Kyra ten years of her. And every single time since then she has known better and every single time she has been right — and Kyra is telling her now, as the person who has been on the other end of it for twenty-four years, that it does not matter that she is right. It is the not being asked. That is the injury. That is the whole of it. She is not shouting, which is the thing Val thinks about afterward; she is crying, and going on talking in a level voice with the children in the trees. All right, Val says. Don't manage me either. She is not — Kyra is correct, about all of it and about her, and Val has known it since a cold store and has gone on doing it because it works. It works, she says: that is the thing nobody says out loud. It works nearly every time, and every time it works it costs somebody a piece of their life that they never get to know about. She will ask him, in front of Ilen, with the document on the table, and whatever he says is what they do — and if he says put his name on it, she will put his name on it, and will not say one word to talk him out of it. And if he says bury it? Then it is buried, and four people go up in two years, and they live with what they did. He won't say bury it. No. He won't. They sit a while longer without saying anything, which is not a thing either of them has ever been able to do comfortably. Down in the trees Genie is shouting about something. Kal is not. *I don't know how to do the next part.* *Neither do I.* *That's not reassuring from you.* *It wasn't offered as reassurance* — and Kyra laughs once, wetly, and puts her head back, and that is the end of it for that afternoon.

**XI. The Committee** — They ask Jalen Renn in a room at Corran Vayr with the document on the table and Ilen at the end of it, and it takes him about as long as it took in the rain. He reads the four lines about himself twice, then asks what will happen to the four of them if it goes up, and Val tells him in detail without softening any of it: the naming, the doors, the years of being the man it might have happened to. And if it does not go up? Then the second flight goes in eighteen months, says Ilen, and the interval is longer, and nobody outside that faculty will have been told that there is a number. *Right. Put my name on it.* He would like everybody to stop offering him the other thing — he has been offered it four times that year and keeps saying the same sentence. If it is him, it is him, and then it is a fact instead of a rumour about four people. And: she asked him in a yard. Nobody has ever asked him anything in his life. Everybody he has ever worked for has decided and then told him afterward and called it a briefing, and she stood in the rain and made him listen to every word. So put his name on it — and if it costs her something, he would like to be told, and he would like to be told first. The committee sits in the eleventh month and it is a joint one: five from the drive faculty, five from Solara, and a chair from the Assembly who says almost nothing for two days and asks four questions on the third that are better than anybody else's. Eleven people. The science takes a day and a half and survives it. Nobody attacks the conversion, because nobody can — Ilen has shown his working in a way that will be taught for two hundred years. Nobody attacks the crystal or the spars or the dish. A man from the yards spends an hour trying to kill the dish and gives it up in front of everybody and says so, which Val thinks is the single best thing anybody does in three days. The rest of it is about how they came by things. The Vey material first, which takes most of the second morning: nineteen samples obtained without consent twenty years earlier, after a written refusal, from a population of eleven thousand people, by a woman sitting at the end of the table. Val answers every question about it. She answered the same questions on a stone floor at Ossen for four hours in front of a hundred and nine people who were owed it, and this room is not owed it and gets the same answers anyway. Then Renn's panels. In a yard. At Hessen Point. In the rain. With nobody present. Does she understand what it looks like for a woman with a finding on her record to obtain a serving commander's medical panels by a private approach in a yard? She understands exactly what it looks like: it looks like what it is. The proper route was four months and the flight was in fourteen, and she decided that asking him herself was better than not asking him at all, and she told her director the same evening, and every step of the work after it is written down by a second person. And she would do it again, and she is aware that saying so does not help her. The chair from the Assembly writes something down. And the woman from the faculty says that nobody is suggesting she is a liar — the suggestion is that a body of work which rests at two separate points on material the institute did not lawfully hold is not a body of work they can put in front of the Assembly, and that if they do, the first person to read it will not read the science. It is, Val thinks, the best argument anybody makes in three days; it is made against her; and it is correct. They vote on the third afternoon. The Vey material is restricted to the faculty and to Solara's biology building, not to be cited outside either without the written consent of the Ossen holding, which everybody in the room understands to mean never. The interval finding — the eleven seconds, the fifteen, the crystal, the spars, the dish, all of it — is not suppressed. It is *retained*: entered in full into the faculty record, circulated to the four senior people, lodged with the programme, and marked as not for publication outside the faculty pending further work. Nothing is destroyed. Nobody is censured. Ilen Vosse's document exists and will go on existing, and anybody with the right to read it can read it forever. And the second flight is confirmed, unanimously, on the grounds that there is no evidence of harm to any crew member and that the appropriation has been voted. Eleven hands. The voice that was against her appointment six years earlier is in that room and votes, and Val knows that it is, because Belu told her on a staircase on her first day that there had been one and told her he would never say whose it was — and he does not, and she goes out past five people any one of whom might have been it. She walks the perimeter road afterward, all four miles, alone, in the dark. Nobody humiliated her: that is the thing she keeps turning over. Nobody was cruel and nobody was stupid, and the woman who ended it was the cleverest person in the room, and every objection was correct, and the whole procedure was so scrupulous that she cannot find one hour of it to be angry about. And at the end of it Sethal has kept the capability and put the warning in a drawer with a right of access. She gets back at the eleventh hour and writes it up for Kyra in nine lines, flatly, without adjectives, because that is the only voice she has. Then she sits for some time and adds one more: *They did not do anything wrong. That is what I cannot get past.*

**XII. The Eleventh Series** — Ilen Vosse has been telling people since he was eighteen that the mistake in the archive was not a mistake, and has been wrong about it for twenty-seven years, and is about to find out that he was wrong in a very particular way. The final section of the eleventh series has always been the famous problem: it stops — not at the end of a thought but in the middle of a method, four steps into a procedure, with the fifth step referred to and not given, and then eleven pages of applications and checks that all assume the fifth step and none of which make sense without it. Every scholar in four thousand years has read those eleven pages and concluded that the missing portion was lost, and a school of thought holds that he took it with him. What nobody has been able to do is look at the numbering, because the numbering runs in his own reckoning. Ilen can read it now. *There are no gaps.* A man who loses pages leaves gaps: you lose a folio and you get one-to-four and then eight-to-eleven, which is the most recognizable thing in the world and is why the loss theory has stood for four thousand years, because everybody assumed the gap was there and nobody could read the numbers to check. There is no gap anywhere in that archive; it runs clean from the first page to the last. He took the section out and then renumbered the whole of the rest of it, by hand, in the same ink — four hundred and some pages — so that the join would not show. That is weeks of work. It is months. That is months of a man's life spent making an absence look like a whole. Yes, says Ilen, and his voice does something on the word. And here is the part he has not been able to sit down for: the hull number is in the surviving text — the hull number of the vessel he went out in, which was grown *after* the renumbering, which means he did the whole of it before he left. He was not covering a failure and not editing a wreck from somewhere else. He sat in a room with four hundred pages and a pen, knowing he was going, and removed one step and made the removal invisible, and then he went. They take four months proving it and it will not break. The renumbering is in his hand and in his ink and in his reckoning. The removed section is the fifth step of the continuity method — the part that would tell you how to keep a living thing whole through a long interval — and everything downstream of it survives, complete, elegant, and useless, the way a lock survives without a key. What he left behind is enough for a civilization to rediscover a fold, and build one, and fly it, and go a very long way in it. And not enough to do it to a person safely, unless that civilization independently finds the thing he took out. He knew what we'd do, says Val. He knew what anybody would do: you give people ten solved problems and one beautiful unsolved one and they will build the beautiful one. He did not hide the eleventh series, he *advertised* it. He wanted somebody standing exactly where they are standing. Wanting them to get there and not get further? Wanting them to get there and stop and think — which is not the same thing, and which is an enormous amount of faith to put in people four thousand years away who have just spent three days voting. And he says the other thing on the way out, with his coat half on, in the doorway, and then goes home: he was right at eighteen and has been wrong about it ever since. He thought the mistake was a mistake somebody had made about Dael. It was Dael's. He did it on purpose, and Ilen has spent twenty-seven years defending him against the wrong charge. You were right, Kyra says. He was right that Dael did something on purpose; he had it the wrong way round for twenty-seven years; and there are four people in that faculty who have been laughed at for standing next to him, and he would like to be the one who says it out loud before anybody else does. And then, at the stair: does she know what the worst of it is? He took out the one step that would have kept people alive, and he is the only man in four thousand years who ever needed it, and he took it out anyway, and then he got into a ship.

**XIII. You Do Not Cross Alone** — Val has been carrying the sentence for three years and has not said it to anybody, which she is aware is the single most characteristic thing about her. She says it on a Fourthday in the fifth month, on the wall, having decided in the coach on the way that she was going to and having then failed to for the first hour and ten minutes. *I think the missing step is the Pairing.* Kyra goes on looking down the orchard. Say something. *I'm not going to. You've been about to say that since the lander and I have watched you not say it for three years and I am not going to put one word in front of you now.* So Val says the rest of it. An organism inside an interval has no reference — that is all of it, and it has taken her three years to be able to state it in one line. Every process in a Sethal body runs on timing, on eleven thousand things agreeing about what time it is, and the agreement is maintained against the outside: against light and temperature and the turning of a world. Inside the interval there is no outside. There are two, and neither of them has been decided, and a body with no reference begins, slowly and then not slowly, to disagree with itself. Eleven seconds is how long a Sethal organism can hold the agreement on its own. And if there are two of you? Then you are each other's outside. Two bodies in resonant coupling do not need the world to tell them the time; they tell each other. Neither can hold the agreement alone past eleven seconds, and the pair together does not have to, because a circuit does not need to know where it is — it only needs both ends. Then Kyra takes a notebook out of her coat. It is old and the spine is cracked and it has been in a drawer under a shelf in a flat in Aventhal for eight years, and she turns to a page four-fifths of the way through and puts it on the wall between them: *a circuit takes two ends. V. not a finding. do not write down.* Val told her it was not a finding and told her not to write it down, and she wrote it down in front of her, and Val looked down the orchard and said nothing — which is the only time in twenty-five years Kyra has ever won an argument with her by doing nothing. It still isn't a finding, Val says. No: it is a sentence she said on the day she nearly had the whole thing and then made herself stop. The evidence has been in the archive for four thousand years and it takes Ilen four days to find once he knows what he is looking for. The last four series flew animals, which everybody knew, and which had been read as a control regime — and at the head of each run there is a single character that nobody could read until the reckoning was converted, which turns out to be a count. Above eleven seconds, every animal flown alone came apart in the ordering. Every animal flown as a pair did not. Not a majority, not a tendency: every one, in nine runs, out to a duration Ilen refuses to say out loud in the corridor and then says in a room with the door shut, which is a long way past fifteen seconds and a long way short of eleven days. He knew, says Kyra. He knew before the eleventh series existed — it is in the eighth. He built the method on it. The fifth step is not a formula and cannot be: it is an instruction about what you put in the vessel. And he took it out, and renumbered four hundred pages so that nobody could build it without finding it first, and then went out alone on eleven days with no pair and no reference and no possible way of surviving it by his own arithmetic. *Unless he found one at the other end.* And the Vey saying, which Val cannot cite and will not be able to cite in her lifetime, sits underneath everything like a floor: that those who went out in it came back wrong in the reckoning, and the ones that mended were the ones that had somebody. Eleven days of an unclosed interval standing over a high field, and a population of farmers caught in it, and the ones who came out of it whole were the ones who had another body to be a reference for. They had not understood one word of it. They had *noticed* it, which is harder, and they had kept it for four thousand years by doing it rather than knowing it, in a ceremony four separate surveys filed under pastoral sentiment. It is not a metaphor, Val says. It has never been a metaphor. It is an instruction, it is four thousand years old, and it is the fifth step. Kyra asks for the short version — the one that will end up on the front of somebody's paper in two hundred years. Val thinks about it. *You do not cross alone.*

**XIV. Evidence, Not Prophecy** — What frightens Val is not the physics, which is somebody else's, and not the Vey, who are beyond her reach for the rest of her life. It is four sheets of paper in her own drawer. Two women, four regulatory markers, one man who was fifteen seconds in an interval and came out a small fraction of the way toward a state that eleven thousand people on a plateau are born in — and two children, aged five, who were born with it switched on. She writes the argument out in the ninth month in the flattest language she owns, then makes Nesh read it, then Fesk, then sits in a room while the two of them try to break it for an afternoon and cannot. The Vey are coupled to their world's field by something old and structural, and it is not the four markers, because the Vey do not express them — which Val proved five years earlier and which cost her the whole second half of her thirties to say out loud. The four markers are something else: a state an ordinary Sethal body can enter, which two women have entered by two entirely different roads and a man has begun to enter by a third, which is fifteen seconds of exposure to the thing itself. Therefore it is not heredity; therefore it is not destiny, and not a lineage, and there is no bloodline anywhere in it. Therefore it can be acquired. Therefore — and this is the line Fesk reads four times and then gets up and walks round the room — a person could in principle be brought to it on purpose, and a person in that state, paired, might hold the agreement through an interval long enough to take a vessel somewhere no vessel has ever been. That is not a paper, says Fesk. That is a programme. She knows what it is. It is a twelve-page biology paper that ends by telling an Assembly that deep range is survivable. It ends by telling an Assembly that deep range is *not obviously fatal*, Val says — which is the weakest sentence she has ever written and the most dangerous, and she has been at it for nine months trying to find a way to write it that does not do what it is going to do. The children are not in the paper. That is the one thing she will not give and does not have to: the maternal panels are hers, the samples are hers, the consent is her own and Kyra's, and there is no methodological reason to name two five-year-olds in a document about adult acquisition. What is in the paper is two anonymous adult subjects, A and B, with acquisition by two dissimilar routes, and eleven pages of the most careful work of her life. Anybody at Solara could work out who A and B are inside a fortnight. Four people in that building know about the children and none of them has any reason to think about them again, and nobody else would have one for fifteen years. You're building a file, Kyra says. *I am building the smallest file I can.* That is still a file: a thing in a drawer with a number on it, and in fifteen years there will be forty people cleared to read it, and two of those forty will have taught their daughters. Yes. And they have told them nothing. Yes. Neither of them says anything else about it. They made that decision over a basket in one sentence and a half when the two of them were three weeks old, and in five years neither woman has reopened it once, and they do not reopen it now. And the word nobody uses, in any room, in any draft, for the whole of that year, is *chosen*. Val struck it out of a summary Nesh wrote in the seventh month and explained why at more length than the occasion required — that they are not special and nothing about them is a sign; that a sign is a thing that tells you about the future and this is a measurement that tells you about a mechanism; and that the moment anybody in that building starts using the other word they will have stopped doing science and started doing something four thousand years older. Nesh, who has been writing everything down for six years, wrote that down too. It was the clearest thing Val said all year, and it lasted about nine months, and then the programme had a building.

**XV. The Program** — The second flight goes out of the yards in the fourth month and comes back four days later with four people on it and a fault log eleven lines long, all eleven of them trivial. Kyra watches from the instrument floor, which is where she watched the first one, and finds that she cannot make herself look at the plate for the last forty seconds and looks at Ilen's hands instead. It goes eleven times further than the first. The interval is longer, and they modelled it four different ways and were right about none of them, and the actual figure when the clocks are reconciled is a little over two minutes. Two minutes and nine seconds inside a thing whose documented safe duration for a living body is eleven. And the crew walk off the strip on their own feet, and Renn does an interview, and Senara Tevel's mother cries in front of everybody, and a physician goes over all four of them for eleven days and finds nothing. Nothing again. That is the worst possible outcome, says Ilen on the coach eleven days later, and he wants somebody to write down that he said so on the day, because in a year nobody will believe he did. They're alive. They are alive and he is delighted and will be delighted about it for the rest of his life — and there are now two flights and eight people and not one thing wrong with any of them, and a document in a faculty drawer that says there is a number, and no power in that system will ever open that drawer again. They have just been given the most persuasive possible evidence for a conclusion that is not true. You don't know that it isn't. He does not know anything; that is the whole of his position and has been for six years. But he knows what a dish does when you put it somewhere with no reference, and he knows that four people have now been two minutes in a place where the front of a ship and the back of a ship kept different time, and he knows that eight for eight is a number that stops arguments and does not answer questions. Val reads Jalen Renn's second panel in the ninth month with the door shut and Nesh at the bench. The four markers have moved again — further than the first time, and further than the first time by more than the first time had moved from nothing, which is the part she looks at for four days before she writes anything down. A man who was a fraction of the way is now perhaps a fifth of the way, and did it in two minutes rather than fifteen seconds, and is perfectly well, and ate a very large dinner in front of eleven people at Hessen Point the week before and was funny about it. She tells him first, because she said she would. They sit in a corridor outside a hangar with a wind going through it and she gives him all of it, twice, and answers everything. So I'm changing. He is changing in a way she can measure and cannot interpret, in a direction shared by eleven thousand people who are entirely healthy, and she does not know whether it is a wound or an adaptation and neither does anybody else. Will it stop? I don't know. Will it stop if I stop going? She does not know that either, and is not going to guess in front of him. Renn sits with his hands between his knees for a while. Third flight is in two years, and he would like to be on it — and that is not bravery, he wants to be clear: he would simply rather be the one it happens to than sit in a yard reading about it happening to Osk. Would she tell him not to? No. She would tell him everything she knows and let him decide, and would find that extremely difficult, and would do it anyway. Right. Then that is what they will do. The programme gets its building in the eleventh month. It has a name nobody uses and a budget that goes through the Assembly in a single afternoon — because eight people have come home in six years and one of them did an interview, and because the woman who wrote the twelve-page biology paper used the phrase *not obviously fatal*, and eleven people in a hall read it as a green light and were, in the narrowest possible sense, correct. It has a hierarchy within a fortnight. It has a hall. By the end of the following year it has a preparation and selection effort with a countdown measured in decades, and a vessel in the design stage that will not be grown for thirty years. Hollis gets the instrument argument he lost to Kyra seven years earlier and is gracious about it in a way Kyra finds completely disarming and complains about to four separate people. And both women are inside it before anybody asks them whether they want to be: Val's paper is the second document in the file and Kyra's constant is the fourth, and neither of them applied for anything. The appropriation goes through an Assembly in which Vaedom Sorin sits and has sat for twenty-six years, and Val finds out afterward from a man in a corridor that her father neither spoke for it nor against it and was present for the whole debate. He writes to her the following week: four pages, as always, three of them about a boundary dispute in a district she has never visited. The fourth says that he read her paper twice and understood about a third of it, that he made certain the Assembly understood he had not assisted her, and that he also made certain everybody in the hall knew that he could have — and that she will find the second of those worth more to her than the first, and will dislike it, and will be right to. Val puts the letter in a drawer with eleven years of its predecessors and does not answer it for a month.

**XVI. Two Small People** — On a Sixthday in the second month of the following year, with nothing whatever happening, the four of them go up to the orchard at the top of the perimeter road and spend the afternoon in it. The girls are six. Genie has not stopped talking since the eleventh hour of the morning and has recently discovered that a question can be asked again immediately, and is working her way through the consequences of this in a systematic manner. Kal is in a tree. She's going to fall out of that. She isn't. Val, she is nine feet off the ground. She has been up it four times that afternoon and has come down four times, and she has not once put her foot anywhere she had not already had her hand — and Val is watching the tree with the flat attention she gives a plate. Kyra's daughter does not fall out of things. Kyra's daughter works out the whole of it first and then does it, and when she cannot work it out she stands at the bottom and looks at it for eleven minutes and then does something else and does not tell anybody why. Kyra opens her mouth, and shuts it, and sits down in the grass. That is the most anybody has ever told her about her. *You'd have seen it yourself in a fortnight.* No, she wouldn't, and Val knows she wouldn't, and she is not going to pretend otherwise on a Sixthday. The other thing happens at about the fourth hour and is the sort of thing that happens all the time. Genie has got hold of the idea that she and Kal are twins — nobody knows where it came from; a child at the water house, or another child's mother, or one of the eleven people who have said the same thing in front of the two of them since they were a fortnight old. She has been operating on it all afternoon and finally says it out loud, at volume, from the middle of the grass, the way she says everything: *we're the same.* You're not the same. We ARE — Kal, Kal, we're the same, aren't we, we're— You're friends, says Kyra, laughing, which is better, and you were born on the same day in two different houses to two different mothers, so you'll have to make do. The same day? The same day: four hours apart, and nobody planned it, and everybody in Aventhal thought it was very funny. Val does not say anything at all. Kyra looks at her. There is a silence of about the length of one breath, in an orchard, on a Sixthday, with two six-year-olds nine feet away and nothing at all happening, and both women look at the grass, and neither says anything whatsoever — and after a moment Kyra says *four hours, then*, and Genie says something extremely loud about the tree, and it goes past. It is the closest either of them comes in eighteen years. Later, when the light goes and they are getting two children into coats they do not want to be in, Val has Genie's arm in one hand and the coat in the other and is losing, and Kyra has Kal already done up and standing beside her being patient about it. Swap. They swap. Genie goes into the coat in about four seconds for a woman who is shouting about a bird at the same time. Kal puts her hand up into Val's without being asked, the way she has done it since she could walk. Neither of them says anything about that either. They have both been noticing it for five years, and it was funny for the first three, and neither of them could now have said precisely when it stopped being funny.

**XVII. Nearly Identical** — Kyra goes back to her own plateau data in the seventh month for the dullest possible reason, which is that somebody has to write the appendix. The object under the byre is now a known source: she has measured it at eleven inches with an instrument that would have looked like a religious artifact to the girl who rebuilt a housing in a shed on that plateau, and she has a model of its field good to nine places that has been checked by four people. So the appendix is arithmetic. Take the model, propagate it out four miles across a valley through rock and weather and altitude to the four points where a stubborn nineteen-year-old stood with a broken instrument for two years, and subtract. What should be left is nothing. It takes eleven days to do properly and she does it twice, the second time having Rieve do the propagation independently without telling her what it was for. What is left is not nothing. It is very small — smaller than the thing she has spent her life being known for, sitting a long way below the number that made her Account and her name. She would never have seen it at nineteen, and nobody with instruments built before she was forty could have seen it at all. It is not noise. She has spent her whole working life learning the difference, on that plateau and at the observatory and in a cold room at Solara at the eleventh hour of the evening: noise has a character, it changes when the instrument changes, and it is not there in the morning in the same shape it was there at night. This is there in the morning in the same shape. And it is there at all four points, and in the four sets she took with the rebuilt housing and the four she took with the original before she broke it down, and in the modern set she took with Ilen's magnetometer standing eleven inches from four thousand years of a dead man's hull. The same residual, every time, under everything. She sits down on the floor of the instrument hall with her back against the bench leg, which she has done before, in that room, seven years earlier, with the rain going across the fields outside. Then she goes and gets Val out of a meeting. You can't come in here. *I've come in here. Sorry. Four minutes.* She puts the sheet on the table in front of eleven people and does not explain it to any of them. Val looks at it for about nine seconds. Where's the source? Not under the byre. It is not the object — she has modelled the object to nine places and subtracted it and this is what is left. It is not Thennet. And she has been sitting on the floor for an hour working out how to say the next part in a way that does not sound like a woman who has had a very long career. Say it badly. *It isn't in this system.*

**XVIII. Every Eleven Years** — It takes four months and it is the easiest work any of them does in six years, because for once in their lives they know exactly what they are looking for. A residual with a fixed signature and no local source has a direction: Kyra has four points on a plateau, one under a byre, and eleven of Ilen's modern stations, and by the end of the second month she has an arc, and by the end of the third she has something that is not in that system and is not close to it. And then Ilen goes into the archives, which is to say all of them. Field measurements are the dullest data anybody takes: taken continuously, by everybody, for a hundred years, by people characterizing something else entirely, and stored because storing them is cheaper than deciding what to throw away. Nobody reads them. There is no reason to read them. It was in all of them. It is in Sethal's own magnetic record, under a century of weather, at the level of the eleventh decimal place. It is on Thennet, obviously, which is where it ruined a nineteen-year-old's life. It is in the two survey series from the outer bodies, where it was logged as instrument drift by four separate people across sixty years, one of whom wrote a very cross note about it that Ilen has framed. And it is in the station record from the yards, which goes back forty years and is the most carefully kept data in the system, and in which it is plainly visible the moment you know to subtract everything else. And it is periodic. It sits at a level nobody would ever notice, and then for a span of some weeks it strengthens — not much, perhaps a fifth — and then it sinks back, and it does this with a regularity you could set an institute by. Every eleven years. That's not a coincidence, says Kyra. It is very probably a coincidence, says Ilen, and he is going to go on saying that for as long as he can, and she should watch how long he manages. Everything about this is elevens: his reckoning runs in elevens, the safe interval is eleven seconds, the sky stood in two places for eleven days— And there are eleven thousand Vey and eleven buildings at Solara and he has eleven pens. He wants it too; he wants it so much he can taste it, and that is exactly why he is not having it. Write down that the period is eleven years and let somebody in ninety years tell them what it means. The last of it is Val's, and she finds it by reading, because by then she can read the fourth column as well as anybody alive except one man. Sorren Dael took field measurements — of course he did, he took every measurement there was, for forty years, in eleven places, and none of it ever meant anything to anybody because the reckoning could not be converted. It converts now. He had it. Four thousand years ago, on a world with no fold and no yards and no instrument better than something a village smith could have made, a man sat down and wrote a column of numbers with a residual in it with a fixed signature and a period of eleven years, and went on writing it for four decades, and never once said what he thought it was. The phase is continuous with Kyra's. It's the same signal. Four thousand years, and it has not moved, and it has not changed, and it has not stopped. They sit with it, the three of them, in a room at Solara at the eleventh hour of the evening with nobody else in the building. He wasn't looking for a fold, Ilen says at last — that is the thing he has been trying not to say for a week. He was forty years old and he had solved distance ten times and he was measuring a field that nobody else could see, and then he built a method that opens an interval, and Ilen has always assumed those were two separate careers. They weren't. He found it first. He found something in the field of his own world that was periodic and had no source, and spent the rest of his life working out what could make it — and what he built was not an invention. It was an *answer*: a thing that would do what the signal does, in order to find out what the signal is. He didn't invent the fold. No. He found a structure that was already there, and worked out how to use it, and then removed the one step that would have let anybody else use it safely, and went out into it alone to see who was at the other end. The building makes the noises a building makes. And it's periodic, Kyra says. Yes. *Ilen. A thing that is used every eleven years is not a structure. It's a timetable.* Ilen Vosse does not answer her. He sits in a room with two women he has known since he was eighteen years old, on a wet evening in the eleventh month, with six years of it on the table in front of them at last, and looks at the window for a long time. It was always in the data, he says. That is the part he cannot get past: every world, every station, a hundred years of it, and Dael's forty before that — and not one of them ever had a reason to look.

### Themes and structure

**Duration, not distance.** The book's central reversal is that four thousand years of ambition pointed at the wrong variable. Position was solved ten times and costs nothing that matters; what kills you is how long you spend undecided between two endpoints. And the hazard is not a dose you can shield against, because inside the interval duration is not a property of the ship but of every separate piece of what is in it — which the novel demonstrates not with physics but with a control culture nobody designed, in which a fortnight happened eleven millimetres from nothing at all.

**The removed step.** Dael did not lose a page; he excised the fifth step of the continuity method and then renumbered four hundred pages by hand so the join would not show, before he left, knowing he was going. He advertised the beautiful unsolved problem precisely so that somebody would arrive where these three have arrived — and then took out the one thing that would let them go further safely, and went out alone without it. Ilen's twenty-seven-year vindication arrives inverted: he was right that it was deliberate and wrong about whose deliberation it was.

**You do not cross alone.** The series' oldest line turns out to be an engineering instruction. A Sethal body is an agreement about what time it is, maintained against an outside that the interval does not provide; two bodies in resonant coupling are each other's outside. The Vey kept the finding for four thousand years by *doing* it rather than knowing it, in a ceremony that four anthropological surveys filed under pastoral sentiment — and Val, who could cite none of it, states the conclusion in five words.

**Asking.** Val's growth is concrete and measurable: she stands in a wet yard at forty-one and obtains a consent she simply took at twenty-two, and tells Renn first because she said she would, and refuses to tell him what to decide. And it is incomplete, because she then spends a month doing arithmetic about his life on his behalf — until Kyra names the injury with total precision: that being right has never been the issue, and the not being asked is the whole of it. Val's answer is the most honest thing she says in the book: that it works, nearly every time, and every time it works it costs somebody a piece of their life they never learn about.

**Nobody did anything wrong.** The committee is the book's quietest horror. Every objection raised against Val is correct; the cleverest person in the room is the one who ends her; nothing is destroyed, nobody is censured, the warning is retained in full and made permanently available to anyone entitled to read it — and the capability is kept and the flight is confirmed, unanimously. Her nine-line report to Kyra ends with the only sentence she cannot get past.

**Evidence, not prophecy.** Val's fiercest insistence all year is lexical: the two girls are not special, nothing about them is a sign, and a sign tells you about the future while a measurement tells you about a mechanism. She wins that argument, for about nine months, and then her own carefully hedged phrase — *not obviously fatal* — is read by eleven people in a hall as permission, and the programme gets a building, a hierarchy, a hall, and a countdown measured in decades. Both women are inside it before anybody asks them.

**Eight for eight.** The second flight returns clean from two minutes inside an eleven-second limit, and Ilen calls it the worst possible outcome and wants the date recorded, because it is the most persuasive available evidence for a conclusion he believes is false. The novel is scrupulous that he cannot prove otherwise — and that Renn's markers have moved again, further and faster, in a man who is entirely well and eats a large dinner and is funny about it.

**Four hours.** The one thing the two mothers will not say is said *to* them, repeatedly, by people who do not know they are saying it — and when a six-year-old shouts in an orchard that she and her friend are the same, it is the closest either woman comes in eighteen years. The decision made over a basket in a sentence and a half holds, unreopened, while the file it must eventually be told against grows a number and a drawer and forty cleared readers.

**It was always in the data.** The closing movement is the book's thesis about attention rather than intelligence: a signal present in a century of everybody's dullest measurements, logged as drift by four separate people, visible at the eleventh decimal place in the most carefully kept record in the system — and in a dead man's forty years of columns before any of it. Periodic, unmoved, unchanged, unstopped. And Kyra's last line reframes the whole series: a structure that is used every eleven years is not a structure. It is a timetable.
