Jack O'Sullivan knew this about Chicago. He had lived here his entire thirty years, and he knew that the rain was not weather but atmosphere, a kind of permanent fog of moral ambiguity that clung to the buildings and the people and the streets like grease. He had grown up in it the way a fish grows up in water, and he had learned, as all fish eventually learn, that the water is not clean and it is not dirty and those are the wrong questions.

His father had brought him to City Hall on a Tuesday in March. "There's a position," Frank O'Sullivan had said, lighting a cigarette in the car park because he smoked everywhere, even in enclosed spaces. "Special coordinator. Cross-departmental liaison. Sounds like bullshit, I know, but it's a foot in the door. And the door is the only thing that matters."

Jack had nodded. He was wearing a suit his father had bought him, navy blue, slightly too wide in the shoulders, and he felt like a boy playing his father's game. He was a University of Chicago law graduate with a specialty in municipal regulation, and he had spent two years at a firm that specialized in corporate litigation, which was a polite way of saying he made other people's problems disappear for money. He had always considered himself more honest than most of his colleagues. Now he was about to find out how honest he really was.

The Boss was a man named Vincent Moretti, though nobody called him that. He was in his sixties, with a face that had been handsome once and had since been reshaped by power into something harder and less human. He sat behind a desk that was larger than it needed to be, which was the point of a desk larger than you needed it to be.

"O'Sullivan," Moretti said, not looking up from the paper he was reading. "Frank's boy. Sit."

Jack sat. The chair was leather and it creaked. The office smelled of cigar smoke and lemon polish and something older, something that had nothing to do with either of those things.

"We have a situation," Moretti said, finally looking up. His eyes were grey and flat, like the surface of a river you should not swim in. "An auditor was found dead last night. Body in the Desplaines River. Police are calling it a suicide. I am calling it a problem."

"What kind of problem?" Jack asked. He heard his own voice and was surprised by how steady it was.

"The kind of problem that involves a ledger," Moretti said. "A black ledger. It contains records going back fifty years. Every bribe. Every election. Every favour. Every name. The auditor had it. Now it's somewhere in this city, and I need it found before it finds someone who shouldn't find it."

"Which someone shouldn't find it?"

Moretti smiled. It was not a warm smile. "Everyone, Jack. Everyone."

Jack took the case because it was his father's case and his father's case was his case and his case was everyone's case in a city where the line between public service and private interest was drawn in water. He started by talking to the police.

Detective Maria Rossi was a woman of about forty with dark hair and a face that had been shaped by years of looking at things she wished she hadn't seen. She worked in the homicide division, which in Chicago was less a division and more a holding pattern for cases that nobody wanted.

"You're the coordinator," she said, not greeting him. It was not a question.

"I am."

"Your father send you?"

"Yes."

"Figures." She leaned back in her chair and studied him. "The auditor's name was Harold Finch. He was fifty-two, married, two kids, and he had a black ledger that documented every corrupt deal in Chicago from 1904 to the present. He was going to give it to the Tribune. Then he was dead. The police say suicide. I say the police are idiots."

"What do you think happened?"

"I think Finch found something he wasn't supposed to find. I think someone killed him. And I think that ledger is still out there, and when it turns up, a lot of people in this city are going to be very unhappy."

Jack asked her to share information. She agreed, reluctantly, because she could tell he was honest and because honest men were rare in Chicago and because she was tired of working alone.

They started by going through Finch's office. It had been ransacked. Drawers pulled out, files scattered, the desk overturned. But Jack found something the police had missed: a loose floorboard under Finch's desk, and beneath it, a manila envelope.

The envelope was empty.

"That's not helpful," Rossi said.

"No," Jack agreed. "But it's useful. Whoever took the ledger took it deliberately. They didn't just grab it in a panic. They looked for it, they found it, and they took it. That means they knew where it was."

"Which means," Rossi said, "they knew Finch was going to give it to someone. Which means they knew he was going to die."

Jack felt the water close around him. The rain continued to hover outside the window.

He went home that night and sat in his apartment and thought about the empty envelope and the ledger that was no longer in it and the man named Harold Finch who had died because he had tried to do the right thing. He thought about his father and his father's friends and the desk that was larger than it needed to be, and he understood, with a clarity that was almost physical, that he was standing in the middle of something that was much larger than him and much older than him and much more powerful than him.

The ledger was in the basement of City Hall. He found out this from his uncle Tony, a man with a face like a bulldog and a voice like gravel, who met him in a bar on State Street and told him over three whiskeys that the ledger was in the basement and that he should forget about it and that for his own good, he should forget about it.

"Why are you telling me this?" Jack asked.

"Because someone's going to find it eventually," Uncle Tony said. "And when they do, they're going to come looking for the O'Sullivans. And when they do, I want you to be ready. Because the ledger doesn't just name politicians, Jack. It names judges. It names cops. It names the people who are supposed to keep this city from eating itself. And when that ledger comes out, the city won't just be unhappy. The city will be dead."

Jack went to City Hall the next night. He went alone, at midnight, with a flashlight and a key his father had given him that opened every door in the building. He went to the basement, and he found the ledger, and he opened it, and he read.

It was exactly what he had feared and exactly what he had hoped for. Fifty years of Chicago politics, documented in meticulous detail. Every bribe. Every election. Every favour. Every name. His grandfather's name was in it, and his father's name was in it, and his uncle's name was in it, and the names of men he had never met and the names of men he worked with every day. It was a book of death, written in the ink of living men.

He sat on the floor of the basement with the ledger open in his lap and the flashlight casting long shadows on the concrete walls, and he read until his eyes burned and his hands went numb.

When he finally looked up, the flashlight was dying. The shadows were longer. The rain was still hovering outside.

He took the ledger home. He put it in a safe deposit box at a bank on Michigan Avenue. He told himself he was going to give it to the Tribune. He told himself this because it was easier than telling himself the truth, which was that he didn't know what he was going to do with it and that the not knowing was eating him alive and that he was beginning to understand what Harold Finch had felt like in those final days, knowing that the truth was in his hands and knowing that hands were not strong enough to hold it.

He stood in front of the bank the next morning and watched the sun come up over Lake Michigan, and he thought about his father and his father's desk and the water he had grown up in, and he understood that the question was not whether he would give the ledger to the Tribune. The question was whether the Tribune was ready for it, and whether Chicago was ready for it, and whether he was ready for what would happen after.

The rain stopped. The sun rose. The city woke up. And Jack O'Sullivan stood on the sidewalk and held the key to the safe deposit box in his pocket and felt the weight of it like a stone.
