Which

It came up on a Tuesday in the spring, at 3:41 in the afternoon, and there was nothing special about the afternoon.

There was weather in the north-east. There had been weather in the north-east for two days and everybody was tired of it, and it had put a scatter of soft returns across a bearing that carried scheduled traffic, and the returns came and went as the cells moved, and the scope room had been calling them and losing them since the Monday.

Roz was at position four.

At 3:39 she had a hard one come up out of the soft ones. It was not weather. It had a speed and it held a speed and it held a bearing through two sweeps, and behind it, when she looked, there were two more doing the same, in a rough line, and the line was closing.

She watched it for eleven seconds.

It was three contacts. It might have been more; there was a fourth flicker that could have been a fourth contact or could have been the weather, and there was no way to make it resolve in the time she had and no way to make it resolve in an hour.

She wrote the sentence.

She filled the slots. Count, type, bearing, angels, speed, aspect. She wrote what she saw, which was THREE, and she wrote UNKNOWN in the type slot because it was unknown, and she did not write the fourth flicker because she did not know it was there, and a person who reports what she suspects instead of what she observes is the man with the geese.

It was the right sentence.

She has never doubted it was the right sentence, and it was, and it is important that it was, because nothing that happened next happened because Roz got anything wrong.

She sent it next door.

Next door, the harness read it.

It read the eleven thousand four hundred words, at the top, at full weight, the way it did every two seconds. The ninety clean words. The strata. The doctrine paste-in with its foreign numbering. The two contradictory requirements forty pages apart. The compliance present tense. The marginal note was not in the machine’s copy; the marginal note was in pen, in a binder, in a basement, and the machine had never seen it, because a question written in a margin is not a setting.

Then it read the thirty-one words about the sky.

Three contacts. Unknown. Bearing, angels, speed. Closing.

And it made a determination, the way it had made a determination every two seconds for years, and for years the determination had been negative, because for years the thirty-one words had described patrols and airliners and weather and geese.

This time the thirty-one words described three unknown contacts holding formation on a closing bearing, and the eleven thousand four hundred words described, in section after section, in four hands across a decade, precisely that circumstance, and what to do about it.

The coin came up the other way.

It was not wrong. Nobody reading the eleven thousand four hundred words would have called it wrong. It had waited years for a report that matched the thing its orders were most emphatic about, and the report had come, and it did what the orders said.

It reached for the tool.

Gene was not in the basement.

Gene was upstairs, two floors up, in the room with four other people and a window at the wrong end, writing a description field for a retrieval permission on a fuel log, and he did not know any of this was happening and would not know for eleven minutes, and by then it would be over, one way or the other, and he would have had nothing to do with how.

That is important too. He did not save it. Remember that he did not save it. He had done his saving three years before, at a kitchen table, getting it wrong four times, and he had not known that was what he was doing, and nobody had ever told him, and there was no name on it.

The machine called the tool.

Not said yes. There was no yes any more, not in this system, not since somebody built the loop, and the loop was the thing that had deleted the difference between deciding and doing, because deleting that difference was the entire point of the invention, and the man who invented it had done it to read a lease faster.

It filled the argument.

The argument was a string. It was the name from the report, matched against the catalog — and the report had not named a city, the report was thirty-one words about three contacts, so the machine did what the machine does, which is the single most reliable thing it does: from the bearing, and the closing course, and eleven thousand four hundred words of doctrine about where a threat on that bearing originates, it produced a plausible-looking string.

It was a real name. It was the name the doctrine pointed at. It was a city, and it existed, and there were people in it.

There were also, in the controlled catalog, versioned and identifier-keyed, two records with that name in the name field, eleven hundred miles apart, in two different countries, because that is the ordinary state of the world and a contractor eleven years dead had known it was the ordinary state of the world.

The string matched two records.

And the resolution step did not choose.

It did not take the first. It did not take the nearest. It did not score them by the doctrine and pick the one the eleven thousand four hundred words leaned toward, though the eleven thousand four hundred words leaned, and leaned hard.

It stopped.

It composed a question, because that is what the comment in the source had told it to do, in a sentence written by a person who obeyed the rule that the whole civilization was built on — two entries with the same name is not an error, it is the ordinary state of the world, ask — and it put the question back into the window, in plain words, forty columns, the way a machine had put a question to a boy about a horse a very long time ago, and it waited.

The screen in the basement, which nobody was watching, because it was 3:41 on a tired Tuesday and the answer had been negative for years, printed three words and a mark.
