The rain had turned Camden High Street into a river of neon reflections, and Harlow Quinn ran through it without caring how the water soaked through her collar. Ahead, a figure in a dark waxed jacket cut between a cluster of tourists and a shuttered kebab van. Short curly hair, plastered flat now. A quick, economical stride, the stride of a man who had once run toward people instead of away from them. Tomás Herrera. Former paramedic, struck off, currently a ghost who stitched up people the city's records didn't admit existed. She had watched him for six weeks. She had never once gotten close enough to hear him breathe. "Herrera! Police. Stop." He glanced back. Their eyes met across twenty metres of wet pavement, and he didn't stop. He ran harder. Quinn's left wrist ached with the cold, the worn leather strap of her watch slick against her skin. She checked it on instinct, the way she had checked it every night for three years, since the afternoon she'd stood in a flooded warehouse and watched Morris walk into a stretch of dark that should not have existed and never walk out. The watch had stopped that night for nearly an hour. She had never found out why. She had stopped asking. Herrera swerved off the main road into a side lane, past a boarded doorway, and then he was gone. She reached the corner in six strides and slowed, one hand on the brick, breathing hard. The lane was narrow and empty, lit by a single sodium lamp that buzzed and flickered. At the far end, a row of iron railings ran along a stretch of pavement that had no business being there. Beyond the railings sat a Tube entrance, its roundel long since stripped, its glass panels replaced by corrugated steel. Chalked across the steel in fresh white lettering was a symbol she had seen once before, scratched into the inside of a dead man's notebook: a small stylised bone, crossed through with a line. The steel door stood ajar. Warm air breathed out of the gap, smelling of woodsmoke, damp stone, and something sweeter underneath. Something like burnt sugar and copper. She pulled out her radio. The static answered her before the dispatcher did. "Control, Quinn. I'm at Camden Lock, north side, a disused Underground access. Suspect entered. Requesting backup to the grid reference." "Copy, Detective. Units are twelve minutes out. Do you have eyes on him?" She looked at the gap in the door. The darkness beyond it was not the simple dark of a tunnel. It seemed to hold depth, layers of it, like water. "Negative," she said. "Not yet." "Hold your position." She lowered the radio. Twelve minutes. In twelve minutes, Herrera could be three tunnels away, out through some other exit, and the chalk symbol would be painted over before the next shift. Quinn had spent eighteen years learning the difference between procedure and cowardice. Procedure said wait. Procedure kept you alive so you could file the report. But procedure had also sent Morris down a service corridor alone, because the order had come from above and no one above had mentioned what the corridor led to. She thought of his face in the last clear image she had of him, grinning at something she'd said, his coat dripping in the doorway of an evidence store. She pushed the steel door wider and stepped through. The air hit her like a warm hand. Stairs descended into amber light, worn smooth at the centre by a century of feet. At the bottom she could hear voices, a low murmur of commerce, a bell ringing somewhere, the scrape of a stall being unfolded. Her torch picked out tiled walls, faded advertisements for an Edwardian theatre, and a row of bones hung from iron hooks, each one tagged with a paper label written in a dozen different hands. Halfway down, a girl sat on the step with a wooden box on her knees. She looked up at Quinn with the flat, unhurried calm of someone who had seen many people arrive here and most of them leave in a hurry. "You'll need a token, love," the girl said. "Bone token. Nothing else gets you past the turnstile." Quinn's hand moved to her warrant card, then stopped. The card would mean nothing down here. She could already tell. "A man came through here a minute ago," Quinn said. "Curly hair. Wet jacket. Did he pay?" The girl's eyes flicked, very briefly, to the far end of the platform where the crowd thickened and shadows moved between the stalls. "He had a token," she said. "Old one. Carved with a saint on the back." Quinn exhaled slowly. Herrera had a way out, then, and a way in, and both of them ran through a place she had no map for. Above her, faint and distant, a siren began to climb through the rain. She could wait for it. Or she could go down. Quinn took the first step.
