Rain came sideways off the Thames wind and slapped the pavement in sheets. Quinn ran. The suspect had forty metres on her and the shape of a grey hood cutting through the market stalls on Inverness Street. She'd clocked him outside the shuttered chip shop on Camden High Street — the same lean build, the same left-handed fumble for his phone that DS Morris's old snitch had described three years ago in a report nobody had signed. Then he'd seen her face and the whole thing had gone loud. Her shoes hit puddles and the water climbed her shins. Leather watch soaked against her wrist. She keyed the radio without breaking stride. "Control, this is Quinn. I'm southbound on Inverness, single male, grey hoodie, heading for the Lock. I need units at the bridge." The reply broke apart in static. She thumbed the button again and got a burst of white noise shaped like a voice, then nothing. He vaulted a barrier stacked with unsold scarves and knocked a crate of bruised plums into the road. Fruit rolled under the parked vans. Quinn planted a hand on the barrier and swung over, landed wrong on a plum, twisted her ankle and kept moving because the alternative was losing him at the bend. "You're making this worse!" She pitched her voice down the street. He didn't look back. He cut right, down a side street that smelled of wet cardboard and hot fryer oil, and she followed him past a club queue where bodies turned and phones came up. "Police! Move!" The queue folded. A bouncer in a short-sleeve shirt reached for him and caught a fist in the throat for the trouble. Quinn hurdled the bouncer's knees and kept the grey hood in her eye-line. He was good. He didn't sprint in straight lines. He angled for bins, for lamp posts, for the corners of buildings where the light broke and her eye lost the edge of him. Twice he feinted toward traffic and she heard brakes howl and horns start up behind her. The streets began to tilt downward. Warehouse fronts gave way to hoardings covered in flyers and paint. She knew the shape of Camden in her legs after eighteen years and this was the ugly seam between the canal and the railway arches, where the streetlights thinned and the graffiti got older. He dropped through a hole in a fence. Quinn hit the fence with both hands and the wire bit her palms. The gap yawned at the bottom where someone had peeled the metal back from a concrete post. Beyond it, a service road ran down toward the canal, and past that, the mouth of the old Northern line entrance — closed in the nineties, sealed with steel shutters since before she'd made sergeant. The shutters stood open. A wedge of warm light spilled out across the wet tarmac and with it came a smell that didn't belong to any station she'd ever worked. Dried herbs and hot metal and something sweet underneath, like flowers left too long in a jar. Quinn keyed the radio again. "Control, suspect has entered the abandoned station under Camden. I am at the entrance. Confirm units." Static. Then a woman's voice, thin and far away, asking if anyone wanted to place a bet on the darts. The channel had been opened by somebody else entirely and had forgotten to close. She stared at the shutters. The light moved like something liquid behind them, throwing shapes she couldn't parse onto the brickwork opposite. A figure passed inside and for a heartbeat blocked the light — tall, thin, wearing a coat too fine for the weather. Then the figure moved on and the gap in the shutters grinned at her. Quinn drew her warrant card out of habit and put it back. She unbuttoned her coat and checked the kit on her belt. Torch. Baton. Cuffs. No vest, because she'd been eating noodles two streets away when the call had come through, off duty, off book, chasing a ghost from a file the department kept in a locked drawer. Her phone found no signal. She held it up and turned in a slow arc and the bars never climbed. Down the tunnel, a sound rose. Not voices. Voices would have been easier. It was the particular hum a crowd makes when it wants things — low, layered, shifting — and underneath it the clink of coins on stone and someone singing a tune in a language that sat wrong in her ear. Quinn thought about Morris. She thought about the three questions the post-mortem hadn't answered and the fourth one that nobody had dared to ask. She thought about the folder in her flat, the maps, the transit routes, the two previous locations where unlicensed trade had bloomed and vanished inside a lunar cycle. The paperwork had called it an unsanctioned market. Her gut had called it something else. She thought about radio silence and the distance to the nearest marked unit and the fact that if she walked in there, the Metropolitan Police would have no record of where Detective Harlow Quinn had gone. The bouncer's bruised throat would give a statement. The club queue had phone footage. The suspect would keep running and take his grey hood and his file and his secrets into whatever lived under this city, and the gap in the shutters would close behind him like it had never been there. Warm air breathed out of the tunnel and touched her wet face. The singing stopped. In the quiet, someone laughed, and the laugh echoed twice when it should have echoed once. Quinn pulled her coat straight. She switched the torch on and held it low so it wouldn't blind her and shut off the useless radio so it wouldn't crackle at the wrong moment. She stepped through the shutters and the market noise closed over her head like water.
