The safehouse was in a subdivision that had run out of money halfway through being built. Cordell Springs. Phase One finished. Phase Two was a grid of streets with streetlights and no houses on them — lit every night for nobody. I counted eleven completed homes on the drive in. Four had cars. Nobody would ever look for me here, because nobody looked here at all.

I understood the appeal.

Kieran carried my file box in before his own bag. I noted that. I note everything — it is the only aggressive thing about me.

“Upstairs, back left,” he said. “That's yours.”

“Because it's the safest room?”

“Because it has one window, and I can see the road from the hall outside it.”

“So — yes.”

“So yes.”

He set the box on the dining table and squared it to the edge. Not roughly. Exactly. I want to be clear that I did not find this charming. I found it legible.

The house came furnished the way rentals do. A sofa the color of oatmeal. A bowl of decorative wooden spheres. Art chosen by the square foot. There was a laminated card on the fridge with the wifi password on it. There was no wifi.

“Rules still stand,” he said from the doorway.

“All five?”

“All five.”

“Refresh me on the second one,” I said.

“You don't tell anyone where you are. Not your lawyer. Not your best friend. Not your mother.”

“Iris Pell is the prosecutor,” I said. “She is the reason I'm still breathing.”

“She's the reason you're on a list.”

I opened my mouth to argue and he had already gone back out to the car, which I would learn was his entire method of winning one.

I set up at the dining table, because that is where the outlets were, and because I had ninety days and eleven hundred pages — Pell's working set, copies, signed out to me under Ruiz's seal with the custody sheet taped to the lid. It went back to the government when I was done. Nothing in that box was mine, which I suspect was the only reason it came through the door at all.

The Rookwood file is not a file. It is a chain of four charitable foundations, each one auditing the next, all of them audited by a firm the family quietly owns. Money goes in as a donation and comes out as a grant. Clean on both ends.

Filthy in the middle.

One of those foundations bought the building my mother's clinic rented. Then it raised the rent. Then the clinic closed. Then there was a waiting list. She was fourth on it.

I have never once said that sentence out loud.

Kieran came back in with the last box and stopped to look at the room. Not at me. At the room. Corners first. Then windows. Then the stairs.

Then me.

I do one specific thing for a living. Give me nine thousand transactions and I will find the one that doesn't belong. Not because I'm clever. Because I'm patient, and I don't get bored, and I have nowhere else to be. People think they're hiding a number. Nobody hides the number. They hide the reason the number is strange. So over three days in that house, with nothing else to audit, I audited him.

Line one. His boots. Brown, scuffed grey across the toe, resoled at least twice — and the second sole was a different maker than the first. Cheaper. Done somewhere that didn't stock his exact color and didn't ask him to wait. Everything else he owned was new. The jacket still held the fold creases from its packaging. The duffel had a shelf crease down the middle. There was plastic film on his phone's camera lens.

A man had replaced his entire life in the last month or so and kept his boots. You keep the thing you need to be quiet in.

Line two. His hands. Short nails, clean, no ring, no pale band where a ring had been. The middle knuckle of the left hand sat wrong — an old break, set badly, set by somebody who was not a doctor. You don't get a knuckle set at a kitchen table unless a hospital would have asked where you'd been.

Line three. Where he sat. He took the stool at the end of the counter. Back to the wall, sightline on the front door. Which is exactly what you'd expect — and precisely why it took me two days to see the rest of it.

He was not between me and the window.

He was between me and the hallway. The hallway goes to the front door. The front door is where the Marshals come in.

Line four. What he ate. Deputy Ruiz's people had stocked the kitchen before we arrived. Cans, pasta, coffee, a case of bottled water, a bag of apples going soft.

Kieran ate none of it. He ate out of a paper sack he'd carried in himself, and he drank tap water from a glass he filled at the sink, and when I offered him the coffee he said no thank you in a voice that closed the subject like a door.

Four line items. One variance.

On the third night I shut my laptop and he looked up — because he always looked up. “I want to test something on you,” I said.

“No.”

“I'm going to anyway.”

“I know.”

“You're not protecting me from the Rookwoods.” He didn't move.

“You're protecting me from the Marshals.” Here is the thing about a man who never reacts. When he doesn't react, that's baseline. When he doesn't react a half-second slower than usual — that's a confession.

“Say the rest,” he said.

“You don't eat their food. You don't drink their water. You put yourself between me and the door they use — not the road a shooter would use.”

“And on the first night you checked the breaker panel before you checked the locks. You're not worried about a man with a rifle.”

“You're worried about a man with a key.”

The quiet went on a beat too long. Outside, one of the streetlights over nothing at all buzzed and went out. Something moved in his face. It was very small. If I hadn't spent three days cataloguing his stillness I would have filed it as nothing.

He was surprised.

Not that I was right.

That anyone had looked.

“Nobody's ever done that to you,” I said. “Have they.”

“Done what.”

“Read you.”

He stood, carried his glass to the sink, and rinsed it. Which was not an answer — and was.

“Rule six,” he said, with his back to me.

“There is no rule six.”

“There is now. Don't ever do that in front of anyone else.”

“That's the nicest thing anyone has said to me in two years.”

“It wasn't nice.”

“I know,” I said. “That's the problem.”

He slept in the hall. Not in the second bedroom — in the hall, on the floor outside my door, back against the wall, one leg straight, boots on. “There's a bed,” I said.

“There's a hall,” he said.

Upstairs, the lamp had been moved to the left side of the bed — my side, which he had known without being told and had never once explained. I had stopped auditing it somewhere around the second night. Some discrepancies you initial and carry forward.

I turned the lamp on and left it on.

At two in the morning I went down for water, barefoot, on the outsides of my feet, because the stairs were new and cheap and loud in the middle. He was at the kitchen island with one light on.

In front of him was the courier envelope from Iris Pell's office. The document drop. Ruiz had brought it up at six, and it had my name on the front in Sunny's big looping handwriting. It was open. Slit cleanly along the side seam — the way you open something you intend to close again.

He had a pair of jeweler's tweezers in his right hand. He was lifting something off the inside of the flap. A grey square the size of a shirt button, with a hair of wire trailing off it.

He set it on the granite and put an empty glass over it. Then he looked up, and he wasn't surprised at all — which meant he had heard me on the stairs and let me come down anyway.

“Rule two,” I said. My voice came out wrong. “You told me not to tell my lawyer where I am.”

“Yes.”

“Because somebody in my lawyer's office is listening.”

“Yes.”

“And how long have you known that?”

He looked at the glass. At the small grey thing under it, still working, still faithfully reporting a kitchen it believed was two hundred miles away.

“Since before they gave me to you,” he said.
