The rain had been falling for six hours and showed no interest in stopping. It came down in sheets off the Camden rooftops, turned the gutters into rivers, and plastered Harlow Quinn's salt-and-pepper crop flat against her skull. She'd lost her umbrella somewhere around Mornington Crescent. She hadn't lost him. Tomás Herrera. Twenty-nine. Former paramedic, license revoked. Five-ten, olive skin, curly dark hair, a scar on his left forearm he'd never given a straight answer about. She'd been on him since the pub on Delancey Street, where he'd met a woman in a gray coat and passed her something small enough to vanish into a palm. Quinn had watched from across the bar with a glass of tonic she never drank. Eighteen years on the job taught you patience before it taught you anything else. He was fast. Faster than a man who'd spent his life in ambulances had any right to be. He cut left down a service alley between two shuttered restaurants, vaulted a stack of pallets, and didn't look back. Quinn went over the pallets after him, landed badly on her bad knee, and kept going. The rain filled the alley with noise. It hid the sound of her breathing. Her watch — worn leather, water-darkened now — said 11:47. She'd noted the time when she'd left the car. Notes mattered. Morris had taught her that. Morris had taught her a great many things before the night he stopped teaching anything at all. The alley spilled onto a dead-end street behind the canal, a place of graffiti and dumpsters and one flickering sodium lamp fighting a losing war with the dark. Herrera was already at the far end, slipping between two buildings. Quinn closed the distance, coat heavy with water, shoes silent on the wet asphalt. She had the advantage he didn't know about: he thought he'd lost her two streets back, when she'd ducked behind the bus shelter and let him run. He'd straightened up after that. Slowed. A man who believed he was alone walked differently. He walked like a man with somewhere to be. The buildings gave way to a construction hoarding, plywood and scaffolding, and beyond it the black mouth of what had once been a Tube station. Quinn knew the place. Camden Town's forgotten sibling — closed in the seventies, sealed, bricked, forgotten by everyone except the taggers who'd found it and the city workers who hadn't bothered to chase them off. The entrance was a Victorian arch, soot-stained and blind, ringed with iron fencing that looked rusted through. Herrera didn't slow. He went through a gap in the fence like water through a grate, and then he was gone, swallowed by the dark beneath the arch. Quinn stopped at the fence. Rain dripped off her jaw. She put one hand on the cold iron and stood there, breathing, and made herself think. Everything about this was wrong. Wrong enough that a smarter detective would have called it in, backed off, written the report, and let the machine grind. That was the procedure. That was what eighteen years had taught her. You didn't follow a suspect into an unknown structure at midnight, alone, without backup, without a warrant, without so much as a working radio — hers had drowned an hour ago in the same gutter that had taken her umbrella. But procedure was for cases that made sense. This one didn't. Three months of surveillance, and she still couldn't say what Herrera was guilty of. The people he met, the packages he moved, the patients he treated in flats with the curtains drawn — none of it fit a pattern she could name. It fit a shape. She could feel the shape. It was there in the way witnesses went quiet when she asked the wrong question, in the way the file on her own desk kept coming back thinner than she'd left it. And in the way Morris had died. She thought about him then, the way she always did at thresholds. Three years ago, a warehouse in Bermondsey, a call she hadn't been on because she'd swapped shifts to take her mother to an appointment. They'd told her the scene made no sense. No forced entry. No weapon. No explanation for the wounds. The coroner had used the word *inconclusive* four times in a two-page report, and Quinn had read those two pages so many times the paper had gone soft as cloth. She'd never believed the word. There was a conclusion. It was just somewhere she hadn't been permitted to look. This was where you looked. She drew her baton from her coat and went through the gap in the fence. The arch swallowed the rain noise first, then the light. Inside, the old station went down farther than a Tube station should — steps that spiraled rather than descended straight, tiled walls green with mold, a smell that was wet stone and something else, something faintly sweet and turned. She flicked her torch on, then off again, afraid of the beam. She went by touch and memory of the floor. Two turns down, she found the rail. A handrail, bolted to the wall, worn smooth where thousands of hands had gripped it. The public didn't come down here. The public hadn't come down here in fifty years. So someone did. Three more turns and she heard it. Not footsteps. Voices. A low murmur of them, many, the sound of a crowd in a place a crowd had no business being — and beneath the voices, a kind of music, thin and reedy, like a flute played badly and proudly. And light. A faint glow, orange and shifting, coming up from below, painting the moldy tiles in warm colors. Quinn stopped on the stairs and listened hard. The murmur was not alarmed. Whatever was going on down there, it had not noticed her yet. She descended the last flight and came out into the old platform. It was a market. There was no other word for it, though the word felt too small. The platform stretched away into the dark on both sides, longer than any platform had a right to be, and along its whole length people had strung up stalls under canopies of patched canvas and hanging lamps. There were tables. There were crates and cages and bottles. There were things on those tables she could not identify and things she did not want to, jars of fluid with shapes suspended in them, bundles of dried herbs bound with black thread, coins and cards and teeth — teeth, small pale teeth, laid out in rows like a currency. The crowd moved between the stalls, a hundred people at least, hooded and quiet, and not one of them startled to find a police detective standing on the platform in a soaked wool coat. Because they hadn't seen her. Because none of them had looked. At the near end of the market, where the platform met the dark, stood a curtained stall with a single lamp above it, and there was Herrera, shrugging off his wet jacket, and the woman in the gray coat from the pub was handing him something, and he laughed. He looked different here. He looked at home. A woman at the nearest stall had finished her business and was turning away, and her hand brushed Quinn's arm, and she froze, and turned, and looked at Quinn's face. The woman did not scream. She did the worse thing. She tilted her head, and looked at Quinn the way you look at a bill you hadn't expected, and said, very quietly, "You don't have a token." The medallion around Herrera's neck caught the lamplight across the market. Saint Christopher. Patron of travelers. Quinn reached into her pocket. Her fingers closed on the thing she'd picked up off the alley floor twenty minutes ago, the small pale thing Herrera had dropped and not noticed, which she had stepped on and stopped and bent down and taken without knowing why — a knucklebone, drilled through, strung on a cord. She held it up. The woman considered it for a long moment. Then she moved aside. Quinn walked forward into the market, toward the lamp, toward the man, and did not let herself look at the exit behind her again.
