The body was found on the Pacific Coast Highway at dawn. A detective named Tommy Varga, thirty-two, wearing a raincoat that had seen better days and a face that had seen worse. The coroner's report would later say impact trauma. Tommy's last memory was the headlights—two white suns filling the windshield—and then the sound of glass breaking like ice on a pond.

He woke up standing. That was the first thing he noticed: he was standing. The second was the white sheet wrapped around his shoulders, hospital-issue, stiff with starch and smelling of bleach. The third was that the rain was falling through him.

His apartment was in downtown LA, fourth floor of a building that had been an apartment building since nineteen forty-two and would continue to be one until something worse came along. He could see inside through the unlocked front door. Lily was on the sofa, knees drawn up, staring at the ceiling the way she did when she was trying not to cry. He sat beside her. He put his hand on her shoulder. His hand went through.

She did not move.

The missing person report was filed on a Thursday. Lily Varga, twenty-nine, last seen leaving her office on Wilshire Boulevard on a Wednesday evening. No signs of struggle. No enemies, according to her coworkers. No reason to leave. The detective assigned to the case was Tommy's partner from two years ago, a man named Briggs who drank too much coffee and not enough water. Briggs came to the apartment, talked to Lily for an hour, and left with a look on his face that Tommy did not like.

Tommy followed him. Ghosts in film noir can walk through walls but they cannot drive cars. Tommy walked. He walked through rain that did not touch him, past neon signs that flickered in colors he could see but not name, through streets that smelled of wet asphalt and fried food and something older and darker.

Briggs went to a bar on Sunset. Tommy went in after him. Briggs ordered whiskey, neat, and sat in the back booth and stared at the table. A man sat down across from him. Tommy could not see the man's face—the corner was too dark—but he could hear the voice.

Varga's wife isn't missing, the man said. She's bought.

Briggs did not flinch. Who by?

A man named Calloway. Lives in Beverly Hills. Pays well. Has a list.

Tommy felt something move inside him. Not a heart—he did not have one anymore—but something in the shape of a heart. He left the bar and walked to Lily's office. He left the office and walked to Beverly Hills. He stood on the street outside a house with a gate and a guard and a garden that looked like it had been designed by someone who had never seen real plants.

He could not go in. There was a line at the gate—a boundary, a threshold, a rule he did not understand but could feel. On this side, the living. On that side, something else. He stood on the sidewalk for three hours in the Los Angeles sun and watched the front door.

Lily came out at dusk. She was not dressed for coming out. She was dressed for going to dinner. A dark dress, simple, the kind of dress a woman wears when she wants to be invisible. She did not look at the sidewalk. She got into a car that was waiting and it drove away.

Tommy followed on foot. The car took her to a hotel on Santa Monica Boulevard. She went into a room on the sixth floor. Tommy followed. He could go anywhere. The boundaries did not apply to him.

The room was large and empty except for a bed and a chair and a phone. Lily sat on the bed and took off her shoes and put her face in her hands and did not move for a long time. Then she picked up the phone and dialed a number and said: "Tommy. I know you can't hear me. But I'm saying it anyway."

He could hear her. He was standing three feet away. But he was right, she could not hear him. The living cannot hear the dead. It is one of the few absolute laws.

He followed her for weeks. She went to a house in Beverly Hills every day. She ate dinner there. She slept there. She came back to the hotel every night and sat on the bed and talked to a phone that could not connect to him.

Then he found the drawer.

It was in his old apartment, in the desk in the bedroom, in the bottom drawer under a stack of unpaid bills. A letter. Lily's handwriting. He unfolded it with hands that were not hands and read:

Tommy, I am sorry. I am so sorry. I did not leave you. I was taken. But I am not happy. Calloway is not a husband. He is a collector. And I am the collection. Forgive me. Forgive me for staying. Forgive me for not dying with you.

He did not know what to do with the letter. He sat on the floor of the apartment—his apartment, the one he had died in, the one he had haunted for months—and he held the letter and he felt nothing and everything.

Outside, Los Angeles rained. It always rained in Los Angeles, at least in the stories. Tommy stood up. He picked up the white sheet from wherever he had left it—he did not remember—and he wrapped it around his shoulders the way a coat is wrapped around shoulders on a cold night.

He walked out of the apartment. He walked down the stairs. He walked onto the street. He walked into the rain.

He did not disappear. He did not fade. He simply walked, down Santa Monica Boulevard, past the neon signs and the diners and the bars, into the rain that fell on everyone equally, living and dead, and he walked until the street ended and the ocean began and he stood at the edge of the water and looked out at the dark and the vast and the indifferent.

And then he turned around and walked back. There was a letter to deliver. There was a woman in a hotel room who needed to know that forgiveness is not a thing you give someone else. It is a thing you give yourself so you can keep walking.

He walked through the hotel door. He walked up the stairs. He walked into the room on the sixth floor. Lily was sitting on the bed, just as she had been weeks ago, knees drawn up, face in her hands.

Tommy sat beside her. He put his hand on her shoulder. His hand went through.

But she shivered. Just once. A small shiver, the kind a person gets when the air changes for no reason they can name.

She looked up. She looked at the corner where he stood, wrapped in white, silent as the space between notes in a song nobody else can hear.

"Tommy?" she said.

He did not answer. He could not. But he nodded. Just once.

And then he stood up, walked to the window, opened it, and stepped out into the Los Angeles night.
