The rain came sideways down Camden High Street, hard enough to sting, and Harlow Quinn ran through it with her collar up and her radio dead in her pocket. Forty metres ahead, Tomás Herrera vaulted a chained-up bicycle rack and kept going. "Herrera!" She got his name out between breaths. "You're making this worse!" He didn't look back. That was the professional part of him, she thought — the paramedic part, the part that had learned to move through a crowd without wasting a single motion. He cut left around a shuttered kebab shop, and the puddle he hit sent up a sheet of water that caught the streetlight orange. Quinn followed. Eighteen years on the job had given her knees that complained on stairs and a lung capacity she maintained out of pure spite, four mornings a week on the towpath at Limehouse. She kept him in sight. That was all she needed. Keep him in sight and let him tire. He turned right into Inverness Street, past the market stalls folded down for the night, tarpaulins snapping in the wind like sails. A drunk in a Hawaiian shirt reeled out of a doorway and Herrera caught him by the elbow — actually caught him, actually steadied him — and the delay cost him three seconds. Quinn closed to twenty metres. "Tommy." She used the name she'd heard on the wire. "You stitched a man's shoulder in the back of a bar three nights ago. That's it. That's all I've got on you. Talk to me and you walk home." He turned his head then. Just enough for her to see his face under the streetlight, wet curls plastered to his forehead, warm brown eyes wide with something that wasn't fear of arrest. "You don't know what you're following me into," he called back. "Then stop and tell me." He ran. The alley behind Inverness dog-legged into a service road she'd never had cause to walk. Bins, scaffolding, a fire door with a sodium lamp above it buzzing like a trapped wasp. Somewhere off to the north the canal made its low sound under the rain. Quinn's shoes were finished — cheap leather soaking through — and her right sock had gone cold and heavy, and she thought about Morris. She always thought about Morris in the running. Three years ago, a Tuesday, a warehouse in Silvertown. She'd gone left and he'd gone right and when she came back around the stacked pallets there was a smell like burnt copper and a pair of empty shoes and DS Alan Morris, forty-six, two kids, a season ticket at Selhurst Park, was on the missing persons register to this day. She'd written the report. She'd written it eleven times before she found a version that didn't get her sent to occupational health. She had not gone right that day. She was going right tonight. Herrera hit the corner of the service road and dropped out of sight. Quinn slowed, one hand out against wet brick, and swung around the corner low. He was gone. The road ended in a hoarding — blue plywood, planning notices peeling in the rain, a graphic of glass flats that would never get built. And in the hoarding, a panel stood open about eighteen inches. Beyond it, black. "Christ," she breathed. She put her torch on it. Concrete steps going down, chewed at the edges, the tiling on the walls a filthy institutional cream with a strip of green. Old Underground tile. She knew that tile. Camden had swallowed a couple of stations back in the day — one under the road junction, sealed since before she was born, the kind of thing that turned up on urban exploration forums and in the mouths of coppers who liked a story. Water ran down the steps in a thin sheet, and the sound coming up from below wasn't water. It was people. A lot of people. A low churn of voices, folded and doubled by the tunnel, and under it something rhythmic — a bell, or a hammer on metal. Light came up the stairwell in colours streetlights didn't make. Green, and a deep bruised violet, and something that pulsed slow and orange like a heartbeat in a chest. Quinn stood in the rain with her torch on the hole in the world and did the arithmetic. Her radio was dead. Her phone had one bar and she'd bet her pension on it having none down there. Nobody at Kentish Town knew where she was because she'd told nobody, because DCI Ainsworth had put the Herrera file in the drawer marked *no* six weeks ago and she'd kept working it on her own time, which meant if she went down those steps she went down as a woman, not a warrant card. Procedure said: mark the location, withdraw, call it in, request support, obtain a warrant for the premises. Procedure had lost her Morris. "Detective." The voice came out of the stairwell. Herrera. He'd stopped maybe fifteen steps down, in that impossible orange light, one hand on the tiled wall. He was breathing hard. Rain ran off him. The Saint Christopher on his chest had come out over the collar of his shirt and it caught the light and threw it back at her. "Come up," she said. "Right now." "I can't." He wiped his mouth with the back of his wrist and she saw the old scar on his forearm, a pale seam from elbow to wrist. "And you can't come down. Not without a token." "A what?" "Bone. Little piece of bone, about the size of a domino." He said it flatly, like a man reading out a dosage. "You need one at the gate. If you walk through without one, they'll take something instead. That's not a threat, that's just what happens. I've seen it happen." A beat. "I've treated what's left of it happening." The rain hammered down on the hoarding behind her. "You're telling me there's a market down there." "I'm telling you to go home." "Eighteen years, Tommy." Quinn came to the edge of the steps. "I've had every kind of nonsense talked at me. Lads swearing blind they were three streets away. Men telling me the blood on their hands came out of a dog. I have never once been told to go home by someone who looked as frightened as you do." "Then listen to the frightened man." He came up two steps, and stopped, like there was a line drawn on the concrete. "Whatever you think I did—" "I don't think you did anything. I think you patch up people who can't go to A&E, and I think you know exactly why they can't." Her voice stayed level. That was a skill. That was the one skill she'd never lost. "Three years ago I lost my partner in a warehouse in Silvertown. His shoes were still standing up. Laces tied. You want to tell me that's not something you've heard about?" Herrera's face did something then, and it wasn't surprise. It was recognition, and he tried to put it away too late. "You know that story," Quinn said. "Detective—" "You know that story." She took the first step down. The tiles were slick and the air came up warm and wrong, tasting of iron filings and cut grass and something sweetly rotten, and every animal instinct she owned told her to turn around and go back into the honest rain. "Silvertown. Say you don't." He didn't say it. Below him the tunnel curved away, and in the curve a shape moved — tall, unhurried, carrying a lantern that gave off no smoke — and the churn of voices swelled and dropped like a tide going over shingle. Quinn's hand found her left wrist without her telling it to, thumb on the worn leather strap of the watch. Twenty-three minutes past eleven. She always logged the time. She logged it now, out of habit, out of religion, and then she took the second step down.
