Something Happened

Nakagawa had slept on it, which was the only test the survey had ever trusted, and in the morning it looked the same, which is how you know.

"We knock," said Nakagawa, at the station, before anyone had eaten. "Today. Before the shift, not after. Here is how."

Egede had objections and Nakagawa let Egede have them all, in order, because a rule kept without the objections to it teaches nobody anything, and then answered them in order too.

The rule about the surface, first, since Egede had been going to raise it. Nothing stays on this world that the planet would keep. So the thing set down at the line would be a stone. Not the party's: the planet's. A stone of the upper levels, picked up at the junction and carried down and put on the silt, which was where it had come from and where it belonged, so that when it was left there, nothing would have been left. The planet already kept it. That was the whole point of a stone, and it had taken the party two years and a returned instrument to see that it was what the people below had been telling them the whole time.

Then when. Before. The boulders shifted before the party was anywhere near the margin; that was the thing that made them a knock and not a comment. So the stone went down first, at the start of the shift, before the imager was even out of its case, and the work came after, if there was any work, and if there was not, the party came back up and that was the shift.

Then who.

"One of us," said Nakagawa. "A knock is one person at a door. Three people at a door is something else, and they have a word for it, and we are not going to find out what it is."

"Then me," said Egede.

"Then Aravena," said Nakagawa. "Who fits the squeeze without scraping half the skin off, and who has been asking that question at the bottom of the passage for sixty shifts, into the dark, when the work was done. You didn't know I knew. I knew. It is on the sound channel every night." Aravena had gone a colour, and Nakagawa let that be. "It is the right question. It has been asked from the wrong place. Today it gets asked from the right one, and by the one who asked it."

Then the rest, plainly, the way orders are given when they matter. Light held low. To the line and not one step past it. Set the stone down, on the line, and step back, and wait the interval — the interval the party had measured a hundred times from the other side — and whatever happened in it, or did not, come back through. Nakagawa would write the log.

"And if something is there," said Egede.

"Then something is there," said Nakagawa, "and the log will say so."

Aravena picked the stone at the junction. Not the first one. A good one, the size of two hands, rough, the kind that would not roll, and heavier than it looked, and Aravena carried it to the front the way you carry a thing you do not want to scrape, and went down the third passage with the light held low.

The squeeze was worse with the stone. Everything is worse with a stone. Aravena went in sideways with it held to the chest and got stuck and came out and went in again with the stone turned lengthwise and the whole side scraping, one hand-width at a time, breath held, and thought, in the middle of it, in the narrowest part, with nothing to be done but go on: this is what it was like for him. Except his was heavier, and it woke up.

Then out, onto the silt, on the far side, into the fungus-dark, with the light low.

And there was someone standing on the line.

Aravena stopped so completely that the stone nearly went.

In the open. Right there. At arm's length of the place where the party's own feet had stopped, where the unit had stood on its base with its face toward them, where nobody had ever stood. Large. Larger than the shapes at the bottom of the margin had ever looked, because those had been far away and this was not. Grey, against the stone. Upright. Still — not the stillness of a thing that has not noticed you, but the other kind, the kind that has, and is waiting to see what you do. The low light lay across the silt and found its feet, and Aravena's hand, without being told, lifted the light a little, slowly, and it went up, and up, and there was a face, and the face was looking at Aravena.

It did not withdraw.

Every part of Aravena that was not the eyes wanted to go back through the crack. Aravena knew this about themselves, standing there, the way you know a thing plainly for the first time. The wanting was very large and it was very simple and Aravena did not do it. Aravena stood on the silt with the stone held to the front and looked at the one on the line, and the one on the line looked back, for as long as it took to get the breath back from the squeeze, which was a while.

Then Aravena did the thing they had come to do, because it was the thing they had come to do, and there was nothing else.

Knelt. Set the stone down on the line — on the silt, a hand from those feet, exactly on the line where the party's feet had stopped, because that was where a thing at a door goes. It made the sound a stone makes when it is set on ground. Small. Plain. Aravena stood up, and stepped back, one step, toward the crack, away from the stone, leaving it. The way they left the place to the party. The way you leave a thing at a door.

And said the thing.

Aravena had known what it would be since the morning, and said it, facing the one on the line, and it went up at the end, the way it always did. What it was is not in any log. The unit was at the junction. Aravena never filed it, and Nakagawa never asked, and the survey does not record what it was not given.

Then Aravena waited. The interval. The one the party had measured from the other side a hundred times without ever once knowing what it was for.

The one on the line bent down.

It put a hand — it had hands — on a rock at the edge of the silt, a big one, bigger than the stone Aravena had carried, and moved it. Just moved it, a little, the way you move a thing so that it is somewhere else. The rock ground against the floor and the floor took the sound and the sound went through the silt and through Aravena's boots and Aravena heard it, the way the party had heard it a hundred times from the upper levels and logged it and never known — a shift of rock, below the margin, felt more than heard.

The knock.

Aravena stood very still, in a new way, for about as long as it takes to say a name, while the whole of it arrived: the boulders, two years of boulders, every arrival, and what they had been, and that this was one, and that it had been done for Aravena, in answer, a hand from Aravena's own stone.

Then Aravena went back through the crack. Slowly, with the light held low, not scraping more than they had to, and did not run, and it was the hardest thing Aravena had ever done in the survey and possibly anywhere.

They had heard it at the junction, Nakagawa and Egede, standing in the fungus-light with the imager still in its case. A shift of rock, down the third passage and through the crack, felt more than heard, the sound the party had logged since its first month.

Nakagawa had known what it was before Egede did, because Nakagawa had been waiting for it, and had not been sure it would come, and had not known what to do if it did not. It had come. Nakagawa stood at the junction and let it go through the floor and into the boots and did not move, and thought: that is an answer. Whatever it means, it is one. We have been answered.

Then Aravena came out of the third passage with the light held low and a face that Nakagawa was going to remember for the rest of the survey, and stopped, and said, in a voice that had not quite come back yet:

"Something happened."

"Yes," said Nakagawa. "I heard. Tell me. In order."

Aravena told it in order. The stone. The squeeze. The one on the line — in the open, large, still, at arm's length of the place they had stopped, and it had not withdrawn; the party had never seen an adult nearer than the bottom of the margin and never one that stayed. The kneeling. The stone set down. The step back. The thing said, which Aravena did not repeat and Nakagawa did not ask for, because it had not been said to the survey lead. The wait. The rock moved. The going.

"Not him," said Egede. "Not Teddy."

"No," said Aravena. "It was big."

Nakagawa wrote the log at the junction, standing up, in the survey lead's own hand, because this one was not Aravena's to write. It said what had happened and not one thing more. Party announced itself at the line: one member, one stone of the upper levels, set down on the line and left. An adult was present at the line, in the open, and did not withdraw. The party's stone was answered by a shift of rock at the edge of the silt. Nothing said is recorded. The line was not crossed by either party. And under it, where only the survey lead wrote, the count: sixty-three shifts on which nothing had happened, and then this one. So that the file would show, for anyone who read it afterwards, how long it had been true.

"What now?" said Egede.

"Now we have been told we may stand in the doorway," said Nakagawa. "That is all we have been told. It is a great deal. We work. And before every shift, from today, one of us goes down with a stone and sets it on the line and steps back and waits, and only then do we work, and if there is no answer we come back up. Every time. That is the standing order and it replaces the other one."

"Every time," said Egede.

"They have done it every time for two years," said Nakagawa. "We have some catching up to do."

Then the work, such as it was, because there was a shift to log and the imager was still in its case. Nakagawa did the ground. Egede did the wall. Aravena knelt to the unit and said, "Log. Shift sixty-four. Upper junction. Party of three," and stopped, and the unit hummed, low, once, to say it had heard, and Aravena said the rest.

Two years to learn to knock. Nakagawa filed it that evening at the station, in the wind, and did not think it had been slow. Two peoples had kept one line from opposite sides for two years, and the first thing either had said to the other was may I, and the first answer was you may stand there, and everything after that is a longer conversation, and the survey had never once been in a hurry.
