The rain in Los Angeles doesn't wash things clean. It just makes the grime slicker.

My name is Cole Hagen. I was a prosecutor for eight years before the bottle took my edge and the department took my badge. Now I work out of an office on Flower Street that smells like stale coffee and regret, and I take cases that other people don't want to touch.

This one came through Veronica Page.

Veronica is a lawyer who looks like trouble and delivers exactly that. She was thirty-five then, sharp as a switchblade and twice as dangerous. She walked into my office wearing a red dress that cost more than my car and told me she had a case that needed a man who knew how the prosecution thinks.

Victor Novak, she said. Thirty-eight. Polish immigrant. Engineer at NextStep Transit. He shot a guy named Alex Kaimlin in the back of the head at the L.A. transfer station. He confessed. He wants to go to prison. But there's something off about this case, and I need you to tell me what.

I looked at the file. Simple on the surface. Victor loved a woman named Maria. Maria had started seeing Alex, who had arrived by transfer from San Francisco for a business meeting. Victor followed him to the station. Shot him. Done.

But Veronica was right. Something was off.

I started digging. I talked to the cops. Detective Dan O'Mara, LAPD, forty-eight years old, had been on the force since Nixon was in office and carried a grudge against anyone who didn't play by the rules, which was most of us.

Cole, he said when I bought him a whiskey at a bar near the station, this one's clean. Guy walks in, shoots a guy, drops the gun, says I did it for love. What's not clean about it?

But the more I looked, the less clean it got. Victor Novak was an engineer at NextStep Transit. He had been fired six months before the shooting for reasons nobody would explain. His apartment had been searched three times by people who weren't police. And his name kept appearing in documents that had no business being accessible to a private investigator.

Veronica met me at a diner on Sunset. She looked tired, which for her meant she hadn't slept in two days and her lipstick was slightly chipped.

There's something you need to know, she said. Victor Novak isn't who he says he is.

I waited.

His real name is Viktor Novakovic. He was a whistleblower. He tried to tell the press what NextStep does inside those transfer pods. They fired him. Then they tried to silence him. And now he's playing a game I don't understand.

I kept digging. I went to the transfer station at night, when the fluorescent lights hummed and the empty pods gleamed like metal coffins. I talked to the cleaners. I talked to the operators. I talked to a woman named Marta Chen who had been cleaning the pods for twelve years and knew more than she let on.

She looked at me over the rim of her coffee cup and said, You really want to know what happens in there, detective?

I said yes.

She leaned forward. The machine scans you. Breaks you down. Sends you through the wire. And over there, they build a new you from scratch. The old you dies. The new you walks out thinking it's the same person. That's what they tell the public. That's what they tell the regulators. That's what they tell everybody except the people who actually work in there.

What do they tell you?

She smiled. It wasn't a nice smile. They tell us to keep our mouths shut and our heads down, because the people who ask questions don't work for NextStep much longer.

I went back to Veronica. She was waiting in her car, parked outside a bar in the Arts District, drinking something that smelled like gasoline.

I found out who really killed Alex Kaimlin, I said.

She didn't look surprised. Who?

NextStep Transit.

She set down her drink. Explain.

Victor Novak wasn't the killer. He was a test. NextStep sends actors into their stations to test security, to see if anyone is getting close to the truth. Victor was one of them. He was planted at the L.A. station six months ago. His mission was to create a distraction, a murder that would draw attention away from what NextStep was really doing inside those pods.

The real killer was Alex Kaimlin himself. He was NextStep's head of security. He had been cleaning house, getting rid of people who knew too much. Victor was next on the list. So Victor did what any engineer would do. He set up a scene that looked like a crime of passion, knowing that the media would focus on the love triangle and not the machine.

Veronica was quiet for a long time. Then she said, You can't prove any of this.

I know.

Then why are you telling me?

Because I'm tired, Veronica. I'm tired of drinking in the dark and taking cases that don't matter. And this case matters. It matters more than anything I've ever worked on.

She looked at me then, really looked at me, and I saw something in her eyes that wasn't professional interest or sexual curiosity. It was fear. And maybe respect.

Cole, she said, if you're right, NextStep will kill you. They'll kill me. They'll kill anyone who gets in their way.

I finished my whiskey. I've been dead for a long time, Veronica. I just haven't told the cemetery yet.

We went public the next morning. The story ran in the Times, the Herald, every paper in the city. NextStep's stock dropped forty percent by noon. The FBI opened an investigation. Veronica disappeared, which for her was standard procedure.

I stayed in L.A. I still drink. I still work out of my office on Flower Street. But sometimes, when I'm lying in bed at night and the rain is hitting the window, I think about what Marta Chen told me. About the machine. About the old you dying and the new you walking out.

And I wonder if I'm the same Cole Hagen who walked into that bar six months ago. Or if I'm just a copy who thinks he's the original.

It doesn't matter. The rain keeps falling. The whiskey keeps burning. And tomorrow, I'll wake up and do it all over again.
