Rain came down in sheets, slicking the Soho pavement until the neon bled across it in long smears of green and red. Detective Harlow Quinn ran with her coat plastered to her back, her boots throwing up sprays of dirty water, her eyes fixed on the man weaving through the late-night crowd thirty yards ahead. She knew him. Tomás Herrera. Former paramedic, struck off the register two years back, and somehow always within arm's reach of the people she'd been hunting for months. She'd watched the Raven's Nest for three weeks before tonight, parked across from that green neon sign with cold coffee and colder patience. When Herrera had slipped out the side door at half eleven with a duffel slung over his shoulder, every instinct she'd sharpened across eighteen years had told her to move. "Herrera!" she shouted. "Metropolitan Police—stop!" He didn't stop. Of course he didn't. He glanced back once, just long enough for the streetlight to catch the panic in his face, and then cut hard left down an alley between a shuttered tapas bar and a tattoo parlour. Quinn followed. The alley funneled the rain into a narrow torrent that sluiced around overflowing bins. Herrera was fast—faster than a man carrying a bag had any right to be—and he moved like he knew exactly where every loose flagstone and rusted drainpipe sat. She didn't. She'd worked these streets for years, but she had the sudden, unsettling sense that she was running through a city laid over the one she knew, a second map drawn in ink she couldn't read. He vaulted a low wall at the alley's end. She hit it half a second later, planted a hand, swung her legs over, and landed badly on her ankle. Pain lanced up her shin. She ran through it. They came out into a service yard behind Camden's high street, and from there the chase turned strange. Herrera ducked through a chain-link gate that should have been padlocked and wasn't, down a flight of concrete steps slick with moss, toward a hoarding plastered with bleached and curling posters for shows that had closed a decade ago. A boarded entrance to a disused Tube station. Quinn had passed a hundred of them in this city and never thought twice. Herrera didn't slow. He pressed his palm flat against one of the boards, and a section that looked nailed shut swung inward like a door. He vanished into the dark. Quinn stopped at the top of the steps, chest heaving, rain running off the sharp line of her jaw. Her left hand went to her wrist out of old habit, fingers closing over the worn leather band of the watch she'd worn since the academy. Twenty-three minutes past midnight. Three years, almost to the week, since she'd stood at the mouth of another dark place and watched it swallow DS Morris whole. She'd gone in after him then. She'd come out alone, and no inquiry, no report, no honest answer in the world had ever explained what had happened in between. Don't, said the voice that had kept her alive. You don't know what's down there. No backup. No light. No idea what that door is. But she could still see Morris's hand reaching back for her in the dark, and she had spent three years refusing to be the kind of detective who turned away from a door. She drew her radio. "Control, this is DI Quinn. In pursuit of a suspect on foot, Camden, disused station off the high street. Requesting backup at—" She looked around for a street name and found none. The posters didn't give one. Even the hoarding seemed to swallow the streetlight. "—Camden Tube, the closed one. I'm going in." The radio answered with a hiss of static, then a woman's voice, flattened and far away. "...repeat, DI Quinn, your location is not... we have no record of a station at..." The signal dissolved into a sound like wind across a microphone. Quinn looked at the handset, then at the open black mouth of the door, and made the decision the way she made all the ones that mattered—fast, and against her own better judgement. She went in. The dark closed over her like water. She fumbled the torch from her belt and thumbed it on; the beam carved a cone through dust and dripping air. A tiled corridor sloped downward ahead of her, the white tiles cracked and brown with age, advertising boards still bolted to the walls. She followed the slope, ankle throbbing, and the temperature dropped with every step until her breath ghosted silver in the torchlight. She heard him before she saw the change. Voices—low, layered, a murmuring tide that swelled up the corridor from somewhere below. And then the corridor opened, and her torch became unnecessary. Quinn stopped dead. The old platform stretched out before her, but it wasn't a platform anymore. It was a market. Lanterns hung from the curved ceiling on chains, but they burned with light that was wrong colours—deep violet, a green like the sign over the Raven's Nest, a red that pulsed as though it breathed. Stalls crowded the platform edge and spilled down onto the rails where no train would ever run again. The air was thick with smoke and a smell she had no name for, sweet and metallic at once. Figures moved between the stalls—too many of them, and some of them too tall, or too still, or wearing faces that didn't sit right beneath their hoods. A trestle table near the entrance held rows of stoppered bottles whose contents shifted of their own accord. Another offered fanned playing cards that turned themselves over. A woman in a high collar was selling teeth. Quinn's hand drifted to her sidearm and stopped. Every certainty she'd built across eighteen years was sliding out from under her, and she understood, with a cold and dawning clarity, that whatever had taken Morris had not been a story she'd told herself to fill the gaps. A figure at a stall near the foot of the steps was haggling with the keeper, duffel bag still over his shoulder, the rain steaming faintly off his curls. He turned, perhaps feeling her stare, and Tomás Herrera's warm brown eyes found her across the impossible market and went wide. "You shouldn't be here," he called, and there was no triumph in it. Only fear—and, oddly, something like pity. "You really, really shouldn't be here." Quinn took the first step down onto the platform. "Neither," she said, "should you."
