Chapter 1
Clause 9, External Aperture, is seventeen steps, and it is stencilled on the wall of the outer lock in letters as tall as your hand so that nobody has to remember it. You have been saying them out loud since step one, because that is how you were taught, and because there is nobody down here to say them with you. Step eight, seat the inner gasket. Done. Step nine, obtain committee authorisation, Form 9-A. You said that one too, in the same voice as all the others. Then you put both hands on the wheel and did step ten. Somewhere behind you a relay closes that has not closed in your lifetime. In your ear, Odile Fitch is still reading. She is in the control room with the plant behind her — you can hear its low note under her voice, the same note it has made every day you have been alive — and she reads the way she reads everything, flat and unhurried and all the way to the end of the sentence. "—and where authorisation cannot be obtained within the scheduled sitting, the applicant shall await the next scheduled sitting. That's the sixth. That's eleven days. I'm not stalling you. I want you to hear that I read it." The door opens ten centimetres and stops. That is not a fault. That is step twelve: the aperture holds at ten centimetres for four minutes while the sample runs. So you stand in a strip of daylight the width of your palm with your hand still on the wheel, and what comes through the gap first is not light and it is not a reading. It is woodsmoke. Underneath it, faintly, onions. Then the door finishes. There is a hillside. There is a road at the bottom of it with weeds up the middle. There is weather, moving. And twenty metres out, on the flat by the road, there is a folding chair. The woman in it stands up and brushes off the front of her coat, unhurried about it. Behind the chair is a wooden crate with a logbook on top in a plastic sleeve, and the grass between the chair and the road has been walked flat, and not this week. The handheld on her hip comes up at the top of the hour, the way it does everywhere out here, and she does not reach for it. "This sector was lost. Do not approach." She waits it out. Forty seconds, the two of you standing there. Then she takes a pencil out of her coat. "Card number," she says. "Two letters, five digits, and the letter in the corner. I have to log it — that's not me being difficult, that's just how we do it." In your ear, Fitch: "Confirm you are at the aperture and have not proceeded past step nine."
