The rain in Chicago doesn't fall ? it hangs. It sits in the air like a second sky, gray and heavy, and by the time it hits the ground it's already part of the river. Kate Callahan sat in her car parked outside the federal penitentiary on State Street and watched it run off the windshield in rivulets, thinking about how much she hated this job and how much she hated that she was good at it.

She was twenty-nine. She'd been in the Bureau for seven years. She'd worked Chicago for three. She had a one-bedroom apartment on the South Side that smelled like stale coffee and regret, a desk that wobbled if you looked at it wrong, and a reputation for asking questions that made men sweat.

Tonight's question was about a man named Tommy O'Brien. Scarface Tommy. He'd been a muscleman for the Outfit in the Twenties ? punched things for money, broke knees for favors, and had a face that looked like someone had taken a meat tenderizer to it and called it a day. He'd also disappeared two weeks ago, along with three members of his own crew.

The fourth member was still alive. He was in the penitentiary's isolation ward, and he was talking to someone he had no business talking to.

"Agent Callahan," the guard said when she entered the corridor. He was a big man named O'Malley, built like a refrigerator and with the emotional range of one too. "You're here to see Moretti."

"I'm always here to see Moretti," Kate said.

Moretti was in Cell 7. Not a regular cell ? a reinforced room with a steel door, bulletproof glass, and a guard posted outside twenty-four hours a day. He'd been there for eleven years, convicted of four murders that had never made the newspapers. In Chicago, that was a specialty in itself.

Kate sat across from him. The glass between them was thick and slightly green-tinted, the kind of glass designed to keep things in and out simultaneously. Moretti was sitting on the edge of his cot, hands folded on his knees, looking at her with eyes that were dark and patient and utterly devoid of fear.

Dr. Victor Moretti had once been Chicago's most sought-after private physician. He'd treated politicians and socialites and the wives of mob bosses. Now he was a prisoner in a federal penitentiary, and the only people who visited him were federal agents and men who wanted information.

"Agent Callahan," he said. His voice was soft, cultured, the kind of voice that made you lean forward without realizing you were doing it. "You look tired."

"I get that a lot," Kate said. "I'm here about Tommy O'Brien."

"Ah. Tommy. Such a crude name for such a crude man." Moretti smiled. It was not a nice smile. "Do you know what happened to him?"

"I'm asking you."

"I can't answer that, Agent. Privilege against self-incrimination and all that." He paused. "But I can tell you this: Tommy O'Brien is a very angry man. Anger is a powerful motivator. It can make men do extraordinary things. It can also make them extraordinarily stupid."

Kate leaned forward. "What do you know about Tommy?"

"Everything." Moretti's smile widened. "I know he was born in the Pilsen neighborhood to a family of Italian immigrants who worked the meatpacking plants. I know his father died of black lung at forty-two and his mother died of consumption at forty-five. I know he dropped out of school at fifteen and spent the next decade punching people for money. I know he has a scar on his left cheekbone from a bottle fight in 1921. I know he drinks rye whiskey, prefers it neat. I know he sleeps with a knife under his pillow. I know he's looking for me."

Kate wrote that down. Not everything ? just the last sentence. "Why is he looking for you?"

Moretti's expression didn't change. "You really don't know, do you? You're sitting here, across from me, asking questions, and you have no idea what you're looking for."

"Try me."

Tommy O'Brien was looking for me because I ruined his family." Moretti's voice was quiet, almost clinical. "His grandfather was a foolish man ? proud, powerful, convinced that his money made him immune to the natural world. He came to me for treatment ? not for an illness, but for a weakness. A weakness I diagnosed, documented, and corrected. The consequences were... unforeseen."

"Unforeseen," Kate repeated.

"He died. His son died. His daughter died." Moretti paused. "Tommy blames me for all of it. I suppose I understand why. But the truth is that the O'Briens built their own destruction. I merely provided the materials."

Kate set her pen down. She'd heard this kind of thing before ? the calm, reasonable explanation of monstrous acts. It never got easier. "You killed three O'Briens."

"I did not kill them. I told the truth about them. There is a difference." Moretti leaned back against the wall. "But that is not why you are here, Agent Callahan. You are here because Tommy is not the only one looking for me."

"Who else?"

"A man named Leo Marchetti. He runs the North Side now ? or he thinks he does. Tommy's crew used to be his. After the O'Brien family collapsed, Marchetti moved in. He wants me dead because I know where the bodies are buried. Literally."

Kate felt a cold feeling in her stomach. "How many bodies?"

"Enough to fill a river. Chicago is a city built on secrets, Agent. The river carries them away, but the river doesn't forget." Moretti's eyes were dark and unreadable. "Marchetti has men searching for me. Tommy has men searching for me. And you have your superiors searching for me. We are three hunts converging on a single point."

"And where is that point?"

"Here," Moretti said. "In this room. With you."

Kate stood. "I'm done for tonight."

"You're always done for tonight, Agent. But the hunts never stop."

She walked out of the penitentiary into the Chicago rain. The city was alive around her ? neon signs reflecting in puddles, steam rising from grates, the distant sound of jazz spilling from a basement club on State Street. Chicago was beautiful in its own way, like a wound that had healed wrong and grown into something strange and terrible.

Kate drove through the night. She went to the South Side first ? Tommy O'Brien's territory. She found him in a bar on 47th Street, sitting in a booth with two other men and a bottle of rye. He was bigger than she remembered, broader across the shoulders, with a face that looked like it had been through a meat grinder and come out the other side still angry.

"Agent Callahan," he said when she sat down. His voice was like gravel in a tin can. "Come to ask me more questions?"

"I came to tell you that I know you're looking for Moretti."

Tommy's eyes narrowed. "Who told you that?"

"Does it matter?"

"It matters to me." He took a drink. The rye went down smooth, but his face didn't change. "I'll find him. I don't care who gets in my way."

"Marchetti is looking for him too."

Tommy set his glass down. "Marchetti is a rat with a gun. He's looking for Moretti to silence him. Moretti knows too much about the North Side."

"Tommy," Kate said quietly. "Why do you want him?"

"Because he killed my family." Tommy's voice was flat, emotionless. "Because he took my grandfather, my father, my mother, my sister, and he made them all disappear. And because I intend to make him disappear too."

"You think killing him will bring them back?"

Tommy smiled. It was a terrible thing to see ? a face like that smiling, all teeth and scar tissue. "No. I think killing him will make me feel something other than this." He tapped his chest, right over his heart. "This feeling. It eats at me. Like acid. I want to feel something else. Even if it's nothing at all."

Kate left the bar. She drove to the North Side next ? Marchetti's territory. She found him in an office above a jewelry store on State Street, surrounded by men who looked like they'd been born with guns in their hands. Marchetti himself was thin, sharp-featured, with eyes like a snake's.

"Agent Callahan," he said, not standing. "What brings you to my neck of the woods?"

"I'm here about Moretti."

Marchetti laughed. It was a dry, humorless sound. "Everyone's here about Moretti. You, Tommy, the Feds, the mob, the priests. He's a magnet for trouble. The question is whether you can survive the trouble he brings."

"What do you know about Moretti?"

"Everything you need to know and nothing you don't." Marchetti leaned back in his chair. "He's not a man, Agent. He's a force of nature. Like a hurricane or a plague. You don't fight him. You survive him."

"Tommy wants him dead."

"Tommy is an idiot with a grudge." Marchetti's smile was cold. "He'll find Moretti, and Moretti will find a way to make Tommy's death look like an accident. And then Marchetti will do the same, and then the Feds will do the same, and we'll all be dead in six months."

"What should I do?"

Marchetti looked at her for a long time. "You should go home, Agent. You should drink a glass of wine, read a book, and pretend you don't live in a city full of monsters. That's what good citizens do."

Kate drove back to her apartment at three in the morning. She didn't turn on the lights. She sat in the dark and stared at the wall and thought about Moretti ? sitting in his cell, calm and collected, knowing things that could bring down half the city. She thought about Tommy ? drinking rye and planning murder. She thought about Marchetti ? calculating, cold, already dead inside.

Chicago was a city of monsters. And Moretti was the king of them all.

She fell asleep at her desk and woke up at nine with a crick in her neck and a phone message from her supervisor: "Moretti escaped last night. Three guards unconscious. Cell door locked from inside. Check the file on Marchetti ? I think Moretti's gone after him."

Kate drove to the penitentiary. The corridors were buzzing with activity ? guards running, doctors examining the unconscious ones, detectives taking statements. Cell 7 was empty. The door was locked from the inside. The window was painted shut.

Moretti had vanished.

Kate stood in the empty cell and felt the rain against the high windows. Chicago was a city built on secrets. And now one of those secrets was loose in the streets, moving through the rain like a ghost, hunting the men who thought they understood power.

She walked out into the Chicago morning and looked at the gray sky and the gray buildings and the gray river, and she thought about Moretti ? wherever he was, whatever he was doing next ? and she knew, with a certainty that sat heavy in her chest, that this was only the beginning.

The city had swallowed its king. And the king had swallowed the city.
