The rain came down in sheets, turning the Soho pavement into a black mirror that swallowed the neon and spat it back fractured. Detective Harlow Quinn ran with her coat slapping against her thighs, water sluicing past her collar and down her spine. Twenty feet ahead, the man she'd been tracking for six weeks ducked between two parked vans and vanished. "Police! Stop!" Her voice cracked against the brick and went nowhere. Tomás Herrera didn't stop. He never did. She'd watched him slip out the back of The Raven's Nest forty minutes ago, a paramedic's bag slung over his shoulder, and she'd followed him through three back alleys and a closed market without him ever once looking like a man who didn't know he was being followed. That was the part that bothered her. He knew. He just wasn't afraid. Quinn rounded the vans. Her boots hit a puddle and the cold went straight to the bone. Up ahead, Herrera cut left down a service lane, the Saint Christopher medallion at his throat catching a stray bar light before he disappeared into the dark. She keyed her radio. Static answered. She'd lost the relay two streets back, the way she always seemed to lose things around these people. Equipment failed. Witnesses recanted. Files corrupted themselves. Three years of this, and it had started the night she'd lost Morris. She shoved the thought down where it lived and ran. The service lane narrowed, walls pressing close enough that she could touch both with her arms spread. Rain hammered the bins. At the end, a chain-link gate hung open, the padlock cut clean and dripping. Beyond it, a flight of concrete steps descended into a mouth of black, the kind of forgotten Tube access the city had bricked up and pretended to forget. Herrera stood halfway down, looking back at her. Water ran off his curls. He wasn't even breathing hard. "You should go home, Detective." "You know my name?" "Everyone knows your name." He shifted the bag higher on his shoulder. The scar on his forearm showed pale under the one working light. "Eighteen years. The detective who keeps asking questions she doesn't want the answers to." "Try me." "No." Something almost like pity crossed his face. "You won't like what's down here. Go back to your reports. Write that you lost me in the rain. It'll be the truest thing you put on paper all year." He turned and went down. Quinn stood at the lip of the stairwell, rain drumming on her shoulders, and weighed it. Procedure said no. No backup, no radio, no light beyond the dying glow at the top of the steps. Following a suspect into a sealed underground space alone was the kind of decision that got an officer's photograph hung in a corridor with a brass plate underneath. But she'd done procedure for three years. Procedure had given her nothing. Procedure had let Morris's case file gather dust under a stamp that read INSUFFICIENT EVIDENCE, while she lay awake at four in the morning seeing the way the streetlight had bent around the thing in the alley. The thing that shouldn't have been there. The thing no one would let her write down. She went down the steps. The temperature dropped with each one. The walls turned from concrete to old white tile, cracked and weeping, the kind they'd laid a hundred years ago when the trains still ran. Her hand found the grip of her torch and she clicked it on. The beam picked out graffiti that didn't use any alphabet she recognised, and a smell rose to meet her — wet earth, copper, and something sweet and rotten underneath, like flowers left too long in their water. At the bottom, the passage opened. Quinn stopped. She'd expected a tunnel. A dead platform, maybe a homeless camp, the usual archaeology of the city's underside. What she got was light. Not electric — the wrong colour for that, too warm and too uneven, throbbing from lanterns strung along a vaulted space that ran further than her torch could reach. Stalls lined both walls. Canvas and salvaged wood, draped in cloth, manned by figures she could only half see. The air moved with voices in a dozen languages, the click of coins that weren't coins, the low murmur of bargains struck in the dark. A market. Under Camden, in a station the maps said had been gone since the war. A boy no older than ten stepped into her path. He held out a small bowl. In it sat what looked, in the lantern light, like teeth. Or seeds. They moved. "Token," the boy said. "What?" "Bone token. No token, no Market." He looked up at her with eyes that held far too many years. "You don't have one. You're not supposed to be here." Quinn's hand drifted to her badge before she caught herself. A badge meant nothing here. She could feel that, the way you feel the floor isn't level before you can say why. Every instinct she'd trained for eighteen years told her to leave — and that same instinct, the one that had kept her alive on worse nights than this, told her the thing she'd been chasing for three years was finally, finally close enough to touch. Down the length of the Market, between two stalls hung with jars that glowed faintly green, Herrera glanced back at her. He shook his head, slow. Then he stepped behind a curtain of hanging bone and was gone. "Lady." The boy tugged her sleeve. "Last chance. People who come in without a token don't always come out the same shape." Quinn looked at the small grasping fingers, at the bowl of moving teeth, at the impossible cavern of light stretching into the earth beneath a city she'd thought she knew completely. She thought of Morris. Of the bent streetlight. Of every report stamped and buried. "Then tell me," she said, crouching to the boy's level, her voice steady in a way she didn't feel, "how I get a token." The boy smiled. It was not a child's smile at all. "Now," he said, "that's the right question."
