XII

I picked the night the way I'd pick a source: for what it was likely to give me.

Theo told me the extra sessions cluster, that they land on a rhythm he stopped writing down on purpose. I've watched Fairview for six weeks, and I've kept a column in the investigation file called visitor nights — the ones where a second car sits in the far corner of the garage past midnight, where the badge elevator by the fire extinguisher runs when Theo swears he never called it. Three data points make a pattern. I have five. Tonight is one of them.

So I booked another in-lab overnight. Suite 6, unusual dream content, page four of the consent form, the same true reason I gave the first time. It costs me nothing to be here. That's the part I keep telling myself while the tech gel dries cold under the electrodes and the lab-issue leads run from my scalp to the wall box, while my own halo sits warm across my forehead and my watch charges on the nightstand where I see the little green heart on its face pulsing along with the one in my chest.

Ten forty. Theo did the hookup at nine, chattering the whole time, a new enamel pin on his collar — a tiny UFO. He showed me the garage recording again like it was the first time. Then he went back to the control room behind the mirrored glass, and the sage corridor went quiet, and Fairview did the thing it does at night, which is stop having a time.

I lie still and I wait and I do not sleep.

Eleven forty. A card reader chirps somewhere down the corridor. Then a suite door, the soft pneumatic exhale of it, and Theo's voice, low, the register he uses for someone half-awake. Suite 9, I think. A sleeper who surfaced and needs settling — a loose lead, a bathroom, a bad dream. It'll take him ten minutes. Maybe fifteen. He'll be in there with the door most of the way shut, his back to the mirror, his hands full of a frightened stranger.

This is the window. He told me its shape himself without knowing he was drawing me a map.

I sit up. I peel the leads one at a time, slow, thumbnail under the tape so the adhesive lets go without a sound, and I coil them on the pillow in the shape of a person still wearing them. The halo I leave on the nightstand. I take my phone. I take nothing else. Socks, no shoes — shoes have a sound and I want to keep mine.

The corridor is empty and lit the color of nothing. I go left, away from the mirror, away from Suite 9, toward the west end where the fire stair is. My pulse is up in my fingertips and I feel every one of them against the phone.

The stairwell door is propped. A folded paper towel, wedged low against the strike plate, exactly where Theo said it lives — the shim that lets the smokers back in without their badges, the small human sloppiness that has outlived three memos telling it to stop. Above the frame, the camera. Dead since spring, its little light off, nobody in a hurry to fix a camera pointed at a door that only opens onto stairs.

I ease the door back on the paper towel and I'm inside the stair, and the temperature drops, and the light goes to raw fluorescent, and I stand for a second with my hand flat on the cold rail listening to the building breathe through the metal.

Then I go down.

The stair is concrete, painted gray, gritty under my socks. Landing, turn, landing. The suites are on this floor; below me there's only the one place the stair can still go, because by code a fire stair connects everything, every floor, all the way to grade — the badge elevator isn't the only way to the lower level, it's only the one they want you to use. The elevator needs a card. The stair needs nothing but nerve and a door at the bottom that I am not sure will open.

That's the part I couldn't scout. Theo's badge beeps red on the elevator; I never asked what the stair door does, because asking would have written the question on his face for the gray man to read later. So I go down not knowing, and the not-knowing sits low behind my sternum, cold and hard, because if the lower door opens and then locks behind me, I am underground with no card to call the car up and a stair door that won't let me back onto my own floor, and the only person who knows I exist tonight is settling a stranger in Suite 9 and thinks I'm asleep.

The door at the bottom is heavier than the others. Gray, no window, a horizontal push bar worn silver where hands have hit it. No reader on this side. I put both palms flat on the bar and I lean, slow, taking up the slack, waiting for the dead stop of a bolt.

It gives.

Not much. A quarter-inch, then the latch clears, and the door swings in on its own weight, and cool air comes up to meet me carrying a sound I felt before I named it — a low continuous hum, machine-steady, the pitch of a lot of fans moving a lot of heat. Server hum. I know it from a dozen data centers I've talked my way into. I catch the door before it can swing wide and bang, and I go through, and I let it settle against my heel so it can't latch, and I stand in the lower level of the Fairview Sleep Institute for the first time.

It doesn't look like a secret. That's the first thing. No blast doors, no keypads glowing red in the dark. A plain corridor, poured floor, exposed HVAC overhead, the same institutional nothing as any basement under any office park in Maryland — which is the disguise, I understand — pre-debunked is the disguise, as sleep study is. The horror never looks like the horror. It looks like a place you'd store old chairs.

To my right, through a wire-glass door, the hum lives: a room of black racks stacked with the small green and amber eyes of running drives, cables dressed in neat bundles, the cold breath of the units pushing out under the door and across my ankles. Session-audio servers. Has to be. Somewhere in that stack, in a folder with my name reduced to a code, is the sound of whatever they've been playing into my skull for six weeks while I thanked them for the sleep.

I don't have time to open that door and I don't have the skill to take anything out of that room that would survive a lawyer. What I have is a phone and a few minutes and my eyes.

I go left, away from the servers, toward two more doors. The first is a small room with a table and a monitor and a foam-lined headphone stand and a swing-arm lamp — a place where one person sits and listens closely to one thing. A review room. On the table, a printed sheet turned facedown, which I do not touch, because a moved page is a tell and a photographed page is not. I get my phone over it and shoot it through the back — the paper's thin enough that the printing ghosts through, columns of it, meaningless from here — and I move on.

The second door is open, and past it the corridor widens into a workspace, and on the far wall, under a strip of light, is what I came down here without knowing I came down here for.

A schedule. Wall-sized. A whiteboard grid gone half-permanent, magnetic cards clipped along the top, dry-erase filling the cells — a master calendar of who gets what and when, the kind of board a small operation keeps because software leaves a trail and a wall doesn't.

I cross to it and I start reading and I make myself photograph before I understand, because understanding is slow and the phone is fast and I do not know how long I have.

Columns. Letters across the top, clipped on their own magnetic tabs. A. B. C. And then D — a wider column, more rows, denser writing, a different marker, and beside the D a longer label I take in as shape before sense, two words, the second one longer, and I have exactly enough time to feel the floor of my stomach drop out of me because Cohort D is real, Marsh said it and stopped like she'd bitten her tongue and here it is on a wall in her building — I have exactly that much time, and I spend it shooting. Left to right. The whole board. Wide, then close, the D column, the labels, the rows of participant codes running down under it, two-letter prefixes and numbers, clinical and bland, a network dressed up as a filing system.

One of the codes in the D column starts with the same two letters that head my own participant card upstairs. My eye snags on it for half a heartbeat, the way your eye snags on your own name in a list too long to read. I don't stop. I can't read it and shoot it both, and the shooting is what I can carry out of here, so I choose the shooting, and I frame the next cell, and I am lining up the row below when the sound changes.

The hum is still there. Under it now, new — a soft mechanical settling, a cable moving in a shaft, the specific sigh of an elevator car arriving somewhere close.

The badge elevator. The one by the fire extinguisher. The one that only runs when someone with a card is coming down to the lower level, on a night the sessions cluster, which is the exact reason I chose this night, which is the exact reason this is happening now.

I kill the phone's screen against my thigh and the corridor goes dim and I stop being a person standing in a room and start being a thing that needs a wall. There's an alcove where the workspace narrows — a supply shelf, a mop sink, shadow. I fold myself into it and I go still, stiller than I have ever made myself, and I put my thumb over the phone's camera so even the lens can't catch a stray gleam, and I listen to the doors part somewhere to my right and a single set of footsteps come out onto the poured floor.

Unhurried. That's what undoes me. Not the sound of a guard sweeping a perimeter. The sound of a man who belongs here, who has been here a hundred nights, who is in no rush because nothing in this building has ever surprised him. Leather soles, an even stride, and then the click of the wire-glass door to the server room and the hum swelling louder for a second and dropping again as the door falls shut behind him.

I get one look. Between the shelf's uprights, across the corridor, the length of him crossing the light — tall, a forward lean at the shoulders like a man ducking a low frame, gray on gray, gone through the glass before the shape finishes assembling into a name I already have.

Then he's in the server room and I am not going to be here when he comes out of it.

I come out of the alcove low and I do not run, because running is footfalls and footfalls carry down a hard corridor, so I walk, heel and roll, back the way I came, past the review rooms, my socks silent on the poured floor and my whole body one held breath. The stair door is where I left it, kissed shut against the latch, not locked, and I get my fingers into the gap and pull it toward me by degrees and slip through into the cold raw light of the stair and let it close behind me one soft ounce at a time until the latch takes with a click I feel in my teeth.

Up. Landing, turn, landing, faster now that concrete and a fire door are between me and that room, my hand skimming the rail, my chest working, the cold hard thing behind my sternum dissolved into something hot and electric that has me taking the last flight two steps at a time. At the top: the door onto my floor, and the paper towel, still wedged low against the strike, still doing its dumb faithful job — and the relief of that folded gray scrap is so total it's almost grief, because if a memo had won this week I'd be trapped in a stairwell over a room with the gray man in it.

I ease it open on the shim. The corridor is empty. The mirror at the far end shows nothing but its own dim length. Suite 9's door is still most of the way shut, and behind it, low, Theo's voice, still settling his sleeper, still turned away, still — without the least idea he's doing it — standing watch over the wrong end of the hall for me.

I'm back in Suite 6 with the door closed before my hands stop shaking enough to work the tape. I peel the coiled leads off the pillow and press them to my scalp, gel to gel, tacking the person I'm supposed to be back onto my own head. Halo across the forehead. Watch on the wrist. I lie down in the shape I left and I make my breathing long and even, and I try not to think about the eleven minutes of dead channels sitting in the record on the far side of that glass — eleven minutes where the machine watched a pillow — and I wait for the door.

It comes at twelve twenty. The soft chirp, the exhale, and Theo's head around the frame, penlight low so it won't wake me.

"You good?" A whisper. "Thought I heard you up."

"Bathroom." My voice comes out furred with a sleep I haven't had. "Couldn't find the light."

"Yeah, they hide it. Sorry." The penlight sweeps my leads, finds them all seated, moves on. He believes me because he has no reason on earth not to, because a propped door and a dead camera and a kind kid's trust are the three things that got me down those stairs and back, and not one of them will ever know it. "Get some sleep. I got you."

I got you. He pulls the door shut soft behind him.

I lie in the dark of Suite 6 with the halo warm and my heart loud and my thumb finding the phone under the edge of the mattress where I stashed it, the screen still black, the gallery on it full of a wall I photographed faster than I read.

I have it. Not clean, not complete — a facedown page shot through its back, a whiteboard grabbed in the four minutes before a man in gray came down to do whatever he comes down to do. Blurred at the edges, cropped where my hands rushed. But I have it. Columns and letters and a D that Marsh flinched off of, and rows of codes I never got to sit with, running down under a label I saw as shape before I ever saw it as sense.

There's a picture on this phone I still haven't looked at closely.

I don't look now. I put the phone back under the mattress and I lie still and I let the halo do the only honest thing in this building, and I do not sleep, and I wait for a morning I can carry all of this out into the light.
