The rain in Chicago never stopped. It slowed, sometimes. It paused. But it never stopped. It fell on the Loop and the stockyards and the tenements of the West Side and the mansions of Gold Coast with the same indifferent persistence, as if the sky itself had decided that the city deserved to be wet and was not going to argue about it.

Silas Vane lived above a speakeasy on South Wacker Drive. The speakeasy was called The Blind Pig and it served whiskey that tasted like turpentine and music that tasted like something else entirely. Silas didn't go there much. He drank cheap whiskey in his room and listened to the pipes rattle and tried to forget what he had heard.

He was thirty-eight years old. He was a night watchman at the Cook County morgue. It was a job he had held for eleven years. Nobody expected much of a night watchman. Nobody expected much of Silas. He was small and unremarkable and the kind of man whose face you forgot the moment you looked away from it.

This was perfect. Invisibility was useful when you did what he did.

The morgue was a brick building on Halsted Street, three stories tall, with a basement where the bodies were kept before they were claimed or buried or both. Silas walked the corridors at night, checking doors, listening to the wind rattling the windows, watching the gaslights flicker.

And listening.

When he placed his hand on a corpse, he could feel it — a warmth, a pulse, a current flowing from the dead into his hands. He didn't know what he was pulling. Energy? Life force? He called it "the spark" in his head, though he rarely called it anything aloud. The spark was enough.

He started small. One body at a time. A few hours of warmth. A few hours of feeling alive in a body that usually felt cold.

Then he started pulling more.

Then he started not caring whose bodies he pulled from.

They were already dead, after all. What harm could it do?

The first time he truly understood the cost, it was too late.

Ruth Callahan was a reporter for the Chicago Tribune. She was twenty-nine, sharp-tongued, and possessed of an investigative instinct that had gotten her suspended twice and promoted once. She had been following a pattern: young men and women, mostly immigrants, mostly working poor, dying in their sleep over the past eight months. The coroner called it "natural causes." Ruth called it a cover-up.

She found Silas one November night, standing over a body in the morgue with his hand on the dead man's chest.

"What are you doing?" she asked.

Silas pulled his hand away. "I'm the night watchman."

"I can see that. What are you doing to him?"

"Nothing. He's dead."

"So are all of them. That's the pattern. But the way you're looking at him —" She stepped closer. "Have you been touching them? All of them?"

Silas said nothing.

"I've been watching you for three weeks," Ruth said. "You come to the morgue every night. Sometimes you stay until dawn. You touch the bodies. You close your eyes. Your face goes pale. And then you leave and you don't come back for days."

Silas looked at her. Her eyes were dark and intelligent and furious. He saw something in her that reminded him of his mother — not visually, but in the way she stood: squared shoulders, chin up, refusing to be made small by the world.

"I can hear them," he said. "The dead. When I touch them, I can feel what they felt. Their last moments."

Ruth stared at him. "You're saying you have a gift."

"I'm saying I have a curse."

"Same thing, different lighting." She pulled up a chair. "Tell me everything."

So he did. He told her about the spark. About the warmth. About the way the spark made him feel alive in a body that had been numb for years. About the way he had stopped caring about whose bodies he pulled from once he realized that most of them were unclaimed paupers who would have been buried in anonymous graves anyway.

"I tell myself they wouldn't miss it," he said. "They're dead. What do dead people need energy for? But then I hear things. Things they felt before they died. And I realize: some of them didn't die naturally. Some of them were murdered."

Ruth's pen moved across her notebook. "Who murdered them?"

"I don't know. But the spark — it's not just in the bodies. It's in something else. Something that's been using me. I can feel it inside me. It's not my power. It's a parasite. And it's been feeding alongside me."

Ruth stopped writing. "A parasite."

"I don't have a better word."

She sat back. "Eight months. Immigrant workers. Natural causes. You touching the bodies. A parasite inside you. This isn't a medical mystery, Silas. This is a pattern. And patterns in Chicago usually lead to one place."

"Where?"

"The Halstead Chemical Works."

Silas went very still. "How do you know about Halstead?"

"Because I've been investigating them for six months. Alistair Halstead — industrialist, philanthropist, founder of the Halstead Chemical Trust. His factories employ three thousand people. His products are sold in every state. And his workers die at a rate that's three times the city average."

"That's not — that could be coincidence."

"It's not. I've cross-referenced the deaths with Halstead's employees. Eight of the eight 'natural cause' deaths worked at Halstead facilities at some point. Two of them were current employees. Six had left within the past year — but not before spending significant time at Halstead plants."

Silas felt the spark inside him stir. Not warmth. Something colder. "You think Halstead is killing his own workers?"

"I think Halstead has been doing something to his workers. Something that makes them die 'naturally.' And I think your little gift — whatever it is — is connected to it."

Silas laughed. It was a dry, humorless sound. "You think the industrialist who owns half of Chicago is doing something supernatural to his workers?"

"I think you feel a parasite inside you that's feeding on dead people. If that's not supernatural, then what is?"

Silas didn't answer.

Ruth stood up. "I need you to do something for me. I can't get into the Halstead facility. But you can. You're a night watchman. You know how to move through buildings unnoticed. I need you to go to the Halstead Chemical Works. Find out what they're doing down in the sub-level."

"There's a sub-level?"

"The blueprints don't show one. But workers have reported hearing sounds from below — humming, mostly, sometimes voices. And there are no windows. The sub-level exists, Silas. I'm sure of it."

"And if Halstead catches me?"

"Then you'll join the list of natural causes."

She left. Silas sat in the morgue for a long time, listening to the rain and the pipes and the dead.

He went to the Halstead Chemical Works three nights later.

The facility was enormous — a complex of brick buildings stretching across six blocks, surrounded by a fence topped with barbed wire. Silas climbed the fence at 2 AM and dropped into the yard and moved through the shadows like a man who had spent eleven years moving through buildings at night.

He found the sub-level entrance behind a false wall in the chemical storage room. The wall was brick, but behind it was a door — steel, locked, with a keypad.

Silas shouldn't have been able to open it. But when he placed his hand on the keypad, the spark flared — hot and sudden and undeniable — and the lock clicked. The door opened.

He descended a flight of stairs into darkness.

The sub-level was vast. Vaster than the building above it should have allowed. Corridors stretched into the dark, lit by gaslights that buzzed faintly. And along the walls — beds. Dozens of beds. And in the beds — people.

Not corpses. Living people. Or mostly living. They were thin, translucent, their eyes closed, their breathing shallow. Tubes ran from their arms to glass cylinders that glowed faintly with a pale blue light.

The spark. It was in the cylinders. The spark was being drawn from these people — not dead, but barely alive — and stored in glass.

Silas felt sick.

He walked along the rows of beds and looked at the faces. Young men. Young women. Immigrants. Workers. They looked peaceful, in the way that people look when they have been drugged into something that resembled sleep but was actually slow death.

At the end of the corridor, in an office that looked out over the beds through a window, Alistair Halstead was waiting for him.

Halstead was a large man with a large face and large opinions. He sat behind a desk that cost more than Silas made in five years and smiled when Silas entered.

"Mr. Vane," Halstead said. "I've been expecting you."

Silas's heart hammered. "How did you know I'd come?"

"Ruth Callahan. I've been watching her. She's clever, but she's predictable. I knew she'd find you. And I knew you'd come here. You have a gift, Mr. Vane — or a curse, depending on your perspective. And gifts like yours are drawn to sources of power. The spark you feel inside you? It's a fragment. A tiny fragment of what's in those cylinders. You've been feeding on the dregs while the real harvest happens down here."

Silas felt the spark stir again — not warmth, but something hungrier. "You're killing them."

"I'm using them. There's a difference. These people are dying anyway. Most of them would be dead on the street within weeks. I'm giving them purpose. Their death serves something greater — the advancement of human knowledge, the extension of human life."

"Your life."

Halstead's smile didn't waver. "My life, and the lives of men like me. The spark extends life, Mr. Vane. I am sixty-eight years old. I look forty-five. I have twice as many years left as most men. And I intend to use every one of them."

Silas looked at the glass cylinders. The blue spark pulsed inside them, slow and rhythmic, like a heartbeat. "You're draining living people to extend the lives of wealthy men."

"I'm optimizing resources. The spark is the most valuable substance in the universe. And these people —" He gestured at the beds. "— they were going to die anyway. At least this way, their death means something."

Silas felt the spark surge inside him. It wasn't warmth anymore. It was rage. Cold, ancient, and utterly without mercy.

He placed his hands on the floor. And he pulled.

Not from the cylinders. From the people in the beds. From all of them, at once.

The spark flooded into him like a dam breaking. Hundreds of lifetimes of energy, of vitality, of something that was not quite life and not quite death but something in between, crashed into his body and nearly tore it apart.

He screamed. The sound was not human. It was the sound of a man whose body was becoming something it was never meant to be.

Halstead watched from the office window, his face pale for the first time. "What have you done?" he whispered.

Silas didn't answer. He was too busy becoming. Becoming something larger. Something terrible. Something that carried the accumulated spark of three hundred and twelve half-dead people in a body that was about to collapse.

He walked out of the sub-level. He walked out of the Halstead Chemical Works. He walked out into the Chicago rain and did not stop walking until his heart stopped and his body fell to the ground and the rain washed over him and the spark inside him flickered — once, twice — and went dark.

Ruth found him three days later, half-dead in the rubble of the Halstead facility, his body ravaged by the energy he had absorbed. He had six months to live. Maybe less.

She published the story. Halstead's empire crumbled. The exposed facility led to a federal investigation that took down a dozen other industrialists running similar operations.

The city celebrated.

Ruth sat in Silas's room above The Blind Pig and held his hand. He was fading. The spark was consuming him from the inside — a cancer of vitality, his body turning on itself.

"Was it worth it?" Ruth asked.

Silas thought about the three hundred and twelve people he had pulled from. He thought about the victims Halstead had drained. He thought about all the lives he had destroyed — not intentionally, but through indifference, through the slow moral decay of a man who told himself that touching dead bodies was harmless.

"Yes," he said. And he meant it.

But then he whispered: "I don't know if I deserved to survive long enough to say it."

He died alone. Ruth was there, but she was not family. She was a colleague who had brought him coffee.

The final scene: Ruth visits Silas's room months later. It is empty. She finds a notebook in the drawer. Inside: thirty-seven names. The names of the dead he pulled from. Thirty-seven names of people who trusted him enough to let him touch them.

She closes the notebook. She puts it in her coat pocket. She walks out into the Chicago fog and does not look back.

Some stories do not have happy endings. Some stories do not have endings at all. They just stop.

Like a heart stopping.
