Rain came off the awnings in ropes and Harlow Quinn ran through it with her warrant card in her fist and her coat hanging open. Tomás Herrera ran forty feet ahead, and he was quicker than her. Twenty-nine years old with a paramedic's lungs. He took Wardour Street at a full sprint, cut between two taxis, and one horn went off in the dark like a swear word. "Police." Quinn slapped the cab's roof as she passed. "Move." The cabbie moved. Herrera swerved left onto Old Compton, doubled back twice on the same block, hunting a gap in her line. He knew these streets better than a man six years off the boat had any right to. She stayed off his shoulder and ran the diagonals instead, cutting through a service alley between a dim sum place and a shuttered jeweller, and came out ahead of him at the corner. He saw her. Stopped hard. Water sprayed off his heels. "Tomás." Her breath sawed. Rain ran into her mouth and she spat it out. "You want to do this here, or in a nice dry room with a table?" He turned and ran the other way. Quinn went after him. They crossed six streets that way, past bins and bolted doors and a night bus that stood in the road with its hazards on and nobody inside. The Saint Christopher medallion had come loose from Herrera's shirt and swung off his neck with every stride, catching the streetlight. His jacket was soaked through. His left arm kept moving strange, cocked at the elbow, holding something against his ribs. The green neon of the Raven's Nest threw itself across the wet road, dyeing the puddles. Herrera passed under it and did not stop. Silas stood in his doorway with a towel over one shoulder. "You're not drinking tonight, then." "Which way." Quinn planted a hand on the door frame. Silas looked at the rain, then at her. "Left. Down the alley behind the bins. And you don't want to." "Why's that." "Because I've watched four people go left down that alley this year and I'm still seeing three of them." She went left. The alley ran narrow between two brick flanks and ended at a chain-link fence with a hole cut in the bottom, and beyond the hole the ground dropped away into a stairwell with a metal handrail twisted off its mounts. Steps went down into black. Water fell in sheets off the fence and made its own noise in the stairwell, a hollow, drumming sound that ran deeper than a cellar should. Her torch beam found the first six steps and nothing after. Old tile. A strip of dead cable stapled to the wall. The name plate above the arch had been chiselled flat, but the shape of the letters stayed in the stone. Camden Town. Nothing else in London was built like this underneath. Quinn stood at the top and listened. Somewhere down there, shoes scraped tile. Then a gate clanged. She took the steps two at a time. The platform had never been finished. Rusted rails ran out of the tunnel mouth and stopped in a wall of poured concrete. Coffered ceiling, broken lamps, tile the colour of old teeth. Pigeons had lived here and left. The air smelled like standing water and someone's cooking, cumin and burnt sugar, and under that, something mineral, like a struck flint. At the far end of the platform a chain-link gate stood open in a frame. Beyond it, light. Real light, warm and moving, thrown by lamps that hung from the ceiling on butcher's hooks. A sound came up the tunnel: voices, hundreds of them, low and constant, with the clink of glass and money and the scuff of feet on stone. Herrera stood at the gate with his back to her, fishing in his jacket. "Tomás." He turned. His face was wet and his chest heaved and his eyes were the eyes of a man doing arithmetic he didn't want to finish. "You should go back up," he said. "You want to tell me about the man in the flat on Bayham Street." "I didn't kill anybody." "Then come and say that in a room with a recorder." "I can't." He pulled his hand out of his jacket. Between his fingers sat something small, pale, the size of a knucklebone, carved with lines that the lamplight sat inside and would not leave. He pressed it to the frame. The chain-link shivered and the gate swung wider. "That's a bone token," Quinn said. Herrera's head came up. "You know what that is." "I know what it is." "Then you know what's through here." He stepped backwards into the light and his voice came back down the tunnel to her, thinner than before. "And you know why I'd rather you didn't." He turned and walked into the crowd and the crowd took him. Heads closed over the top of his soaked jacket like water. Quinn reached the gate and stopped. The market went on further than the torch could carry. Stalls under the lamps, hung with copper and glass, strings of dried things, jars of liquid that glowed the way a fish glows in deep water. A woman with a face full of silver rings sold something out of a case that steamed when she opened it. Two men argued over a box of teeth. Children ran between the legs of the crowd with nothing in their hands and eyes that stayed on Quinn a beat too long. No one looked frightened. Everyone here, every single one of them, stood in a place the Metropolitan Police did not have a map for. She thought about the report. DS Morris, three years ago, pulled from the canal at Wapping with water in his lungs and nothing on his body to say why. The pathologist had filled in four pages and left eleven blank. The coroner had called it misadventure and closed the file in twenty minutes. Quinn had read the file so many times the crease in it had worn through. She had never once been able to say what he'd been doing down there. At her feet, half in a puddle, sat a second bone token. Herrera must have dropped it pulling the first one out. Her torch found it and held it. Warm light poured past her shoulder from the market and threw her shadow down the tunnel behind her. No radio signal. No backup she could call from a station that did not exist. Her phone showed one bar and it flickered when she lifted it. Quinn put the token between her teeth, bent, and checked the chain-link gate for the hinge side, the way she'd been taught in a car park in Aldershot nineteen years ago. The gate had been hung to swing inward. It would not lock behind her. She took the token out of her mouth, put it in her coat pocket, and stepped through. The noise of the market closed over her head. Bodies on both sides. Lamp smoke. A man in an apron selling lengths of braided hair. Quinn walked into the crowd with her coat dripping on the stone and her eyes on the back of a brown jacket, twenty stalls ahead, moving fast and not looking round.
