The apartment near the rail yard was on the third floor of a building that smelled of old carpet and cooking oil.

The door had been opened with a warrant key.

Sergeant Patel walked me through it while a forensics officer worked quietly in the back room.

It was small.

Two rooms and a kitchen.

But it was not what I expected.

One wall of the main room was covered in drawings.

Dozens of them, pinned carefully in rows.

Airplanes, mostly.

Some with two figures standing beneath them.

Some with a sun in the corner and a house with a path leading to the door.

I stood in front of that wall for a long time.

"He drew those," Patel said quietly.

"Ray kept them.

Whatever else he was, he kept them."

In the back room, there was a single bed with a blue blanket.

A shelf with four books.

A shoebox under the bed.

Patel handed me gloves and I opened the shoebox.

Inside: a photograph.

Me, holding Noah the day he came home from the hospital.

The photo was creased from being handled many times.

Underneath the photo, a folded piece of paper.

A child's handwriting, uneven and careful.

*My moms name is.

I don't know her last name.

She has brown hair.

She gave me a necklace.

She is looking for me.*

He had written it in pencil.

The letters were the size of a child who had just learned to write.

He must have been six, maybe seven.

My hands were shaking inside the gloves.

"He wrote that himself," Patel said.

"We think Ray didn't know about it."

I folded it back exactly as it had been and set it in the box.

"I want that," I said.

"When you're done with it.

I want that back."

"It'll be returned to you," she said.

"Along with the photograph."

In the kitchen, they had found something else.

A second phone, prepaid, taped to the underside of a drawer.

The last number dialed was Diane's.

But the call log also showed a number that had called in repeatedly over the past two years — a number registered to a motel forty miles north of the city.

Patel showed me the printout.

"We sent a car this morning," she said.

"The motel confirmed a long-term guest.

Male.

Registered under a different name, but the description matches."

I looked at her.

"Marcus?"

"We don't know yet.

The guest checked out two days ago." She paused.

"But he left something in the room.

A bag.

Inside the bag was a notebook."

She handed me a photograph of the notebook's first page.

At the top, in handwriting I recognized from years of shared grocery lists and birthday cards and one signed divorce paper:

*If something happens to me, start here.*

Below it, fourteen months of notes.

Dates.

Names.

Amounts.

Conversations recorded in careful, frightened handwriting.

Marcus had known everything.

And for fourteen months, he had been writing it down.

"He was building a case," I said.

"It looks that way." Patel took the photograph back.

"Whatever he was before — whatever role he played in the beginning — he spent the last year trying to undo it." She looked at me carefully.

"He may have been trying to protect Noah.

In his own way.

Too late, and badly, but—"

"Where is he now?"

"We don't know." She was honest about it.

"But we're looking."

I walked back into the main room and stood in front of the wall of drawings.

Airplanes.

Dozens of them.

All pointing in the same direction.

I thought about a four-year-old boy who remembered a silver airplane necklace and drew it over and over for five years because it was the one thing no one had been able to take from him.

My phone buzzed.

Claire.

"The emergency custody order came through," she said.

"Noah is legally in your care as of forty minutes ago.

No one can take him."

I put my hand flat against the wall, against the edge of one of the drawings.

"Claire," I said.

"I know," she said.

"I know."

Outside the window, the city was going about its afternoon.

Cars.

People.

Ordinary things.

I stayed in that room a little longer, with my son's drawings all around me, before I went back to him.
