The Wake

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
