Rain came down in sheets over Camden High Street, slicking the pavement into a black mirror that swallowed the neon and spat it back in broken colour. Detective Harlow Quinn ran with her coat flapping at her knees, one hand steadying the radio clipped to her belt, the other braced for the sidearm she wasn't carrying. Twenty paces ahead, the curly-haired bastard she'd been watching for six weeks was making her work for every breath. "Herrera!" Her voice cracked against the brick. "Tomás Herrera, stop where you are!" He didn't stop. He didn't even look back. He jinked left around a cluster of drunk tourists huddled under a pub awning, bumped an elbow off a bollard, and kept going. The Saint Christopher she'd noted in his file bounced against his chest, catching a flare of green from a kebab shop sign. Quinn pushed harder. Her lungs burned but her legs remembered how to do this — eighteen years of remembering. Morris used to joke that she ran like she was being chased instead of chasing. Morris wasn't here to joke about anything any more. The street narrowed. Herrera cut between two parked vans and down an alley that smelled of bin juice and piss. Quinn slammed her shoulder off a wing mirror, swore, and followed. Water sluiced off a broken gutter onto her neck. She bit down on the gasp. "You've got nowhere to go, Tomás. Talk to me and this ends easy." "You don't want to follow me." He threw it over his shoulder without slowing, the words clipped by his breathing, a Spanish lilt underneath. "Go back to your car, Detective." "That a threat?" "A favour." He vaulted a low fence behind a shuttered flower stall. Quinn cleared it less cleanly, caught her shin on the rail, came down hard on the other side. When she straightened, Herrera was already at the mouth of the service stairs that plunged into the old Camden Road Tube entrance — the one boarded up since before she'd joined the force. The plywood hoarding had been hacked through. Fresh splinters. A hinge nobody had bothered to hide. He paused on the top step. Just for a breath. Looked back. In the wet sodium light his olive skin had gone grey. The scar on his left forearm showed pale where his sleeve had ridden up. He wasn't looking at her like a man who thought he'd be caught. He was looking at her like a man deciding whether to warn a stranger off a cliff. "Don't," he said. Then he was gone, down into the dark. Quinn hit the top of the stairs and stopped. Rain drummed on the hoarding behind her. Somewhere above, a night bus sighed through its brakes. Her radio crackled — dispatch wanting an update, her DI wanting an update, the whole orderly architecture of the job wanting her to confirm she was still inside it. She looked down the stairs. They weren't the stairs of a derelict Tube station. She knew what those looked like — she'd walked a dozen of them on evidence runs. These had something at the bottom. A flicker, warm and low, the wrong colour for emergency lighting. A sound, too, under the thrum of the rain: voices, maybe, or a single voice multiplied. The smell drifting up was woodsmoke and something sweeter, something that prickled the back of her throat. Her hand found the radio. She thumbed the button. Let it go. Three years ago she had stood at the mouth of a warehouse in Deptford with Morris at her shoulder, and she had called it in, by the book, and they had gone in together, by the book, and she had come out alone. The report said gas leak. The coroner said asphyxia. Neither of those things explained what she had seen on the floor where Morris had been standing — the shape of him, burned into the concrete, as if he had been lifted out of his own outline and carried somewhere else. Nobody at the Yard talked about it any more. Quinn talked about it every night, to the ceiling, for three years. Herrera's footsteps were fading below. She drew her baton, flicked it open. Useless, probably. She took it anyway. The stairs were slick with rain for the first eight steps and then abruptly dry. She noted it. She noted the way the sound of the street cut off, as if a door she couldn't see had closed behind her. She noted the temperature — warmer down here, like walking into a kitchen. Her training catalogued each thing and filed it in a drawer marked LATER. At the bottom the passage opened out. She had expected platforms, tiling, the bones of a station. She got a market. Stalls crowded the old concourse, canvas and carved wood and something that might have been bone. Lanterns hung on cords that weren't plugged into anything. A woman in a butcher's apron was weighing what looked like teeth on a brass scale. A boy no older than twelve held out a tray of small glass vials to a hooded man who paid him with a coin that sang when it touched the tray. Nobody turned to look at Quinn. Nobody needed to. She felt their attention the way you feel a draught. At the edge of the crowd a stallholder with a face full of tattoos was watching her openly. He raised one pierced eyebrow and held out a hand, palm up. "Token," he said. "I don't have one." "Then you don't have a market, love." She scanned past his shoulder. Herrera was cutting a diagonal through the press of bodies, heading for an archway hung with black cloth. He wasn't running any more. He was moving like a man who'd come home. "Police," Quinn said, low, to the tattooed man. She didn't reach for her warrant card. Some instinct she didn't want to examine told her that word would mean nothing here, or worse than nothing. "I can see that." "I need to get through." "Then you need a token." He smiled, not unkindly. "Or you need to be very sure you want what's on the other side." Across the concourse, Herrera reached the archway. He paused again. Looked back at her across the heads of the crowd. And this time, very small, very deliberate, he shook his head. Quinn's thumb found the catch of her baton and held it there. Water ran out of her hair and down the collar of her coat, and she stood at the edge of a place that had no business existing, and she made her choice.
