The rain had come on in earnest somewhere around Mornington Crescent, and by the time Harlow Quinn turned onto Camden High Street it was running off her cropped hair and down the back of her collar. She ignored it. Her left wrist was slick under the worn leather strap of her watch, and she could feel the seconds ticking against her pulse. Ahead, the man she was chasing cut through a knot of stalled traffic, shoulders hunched, a dark coat flaring behind him. Tomás Herrera. Twenty-nine years old, a paramedic until the General Medical Council had taken his licence, and now, according to three separate informants and one very frightened nurse, the man who put back together the people nobody else would touch. The people who didn't show up in hospital records. The people who bled a different colour. "Herrera! Stop where you are!" He glanced back. Even through the rain and the sodium glare, she saw his face: not panic, but calculation. He lifted a hand to the St Christopher medallion at his throat, the way another man might touch a lucky coin, and then he ran faster. Quinn sprinted after him. Her knee complained. Eighteen years of service had taught her a great many things about pursuit, chiefly that the man who knew the terrain always won, and she had no idea what terrain he was heading for until he swung left, past the shuttered market stalls and the dripping awnings, and vaulted a rusted railing into the mouth of a service road. The road ran downhill, out of the lamplight, toward a squat Victorian façade she half recognised. Arched entrance. Iron gates chained across it. A sign so weathered she couldn't read it, and beneath the sign, the grimy tiled lettering of an old Underground station, its name sandblasted into a single word she could almost make out. Camden Town. Closed since the nineties. Condemned, on paper, for structural reasons. She stopped at the gate. Herrera was already on the far side of it. He had squeezed through a gap where a section of mesh had been peeled back, and now he turned, breathing hard, and looked at her across the wet concrete. There was no fear in his face. There was something closer to pity. "You don't want to come in here, Detective," he said. His accent was softened by years of London, but the Spanish underneath was still there. "Not without a token." "Step out where I can see your hands." "You have no idea what you're following." She had some idea. She had three years of it, and most of that was a nightmare she couldn't prove. Three years since DS Morris had walked into a basement in Hackney with her, a case file in his hand and a grin about something unrelated, and had come out of it as nothing but a scorched patch on the floor and a report full of words like *unexplained* and *no further lines of inquiry*. Morris had never been the kind of man who simply vanished. Neither had she. But something had taken him, and she had spent every night since trying to find the thread. The thread, it seemed, ran underground. "Where does that go?" she asked. Herrera's mouth twisted. "Somewhere the law doesn't follow. It moves every full moon. Tonight it's here." He tapped the iron bars with two fingers. "There's a door at the bottom of the stairs. The man on it wants a bone token. Bone, not bought. You don't have one. I can see it in your face." "Then give me yours." For a moment, she thought he might. Something moved behind his eyes, a softening, a flicker of the paramedic who had once knelt in gutters beside strangers. Then it was gone. "I'm sorry," he said, and he meant it, which was worse. "But if you go in there without one, you won't come out the same, and I'm not going to be the reason your name ends up on a list in that place." He turned and walked away into the dark tunnel. Quinn put her hand on the gate. The metal was cold and slick. Every instinct she'd built over eighteen years, every hard lesson about backup, procedure, and not going in blind, screamed at her to step back, radio in, wait for reinforcements who would never believe a word of what she'd seen. She thought of Morris, his last message on her phone, unfinished: *Quinn, you won't believe what the* She thought of the watch on her wrist, the hands still moving whether she followed or not. Quinn pulled a torch from her coat, flicked it on, and wedged her shoulder against the mesh. The gap was narrow. She turned sideways and forced herself through, feeling the wire snag her coat and then give. Her boots hit wet tile. Below her, the stairs spiralled down into a light that was not electric, pale and shifting, the colour of moonlight through dirty glass. Somewhere far below, a crowd murmured, and a bell rang once, like a warning or a summons. She straightened, drew a breath that tasted of rust and rain, and started down.
