The rain came down in sheets across Soho, turning the neon into smears of colour on black pavement. Detective Harlow Quinn ran with her shoulders hunched, one hand clamped over the radio at her shoulder, the other keeping her coat from tangling around her legs. Ahead of her, thirty metres and closing, the suspect wove through the late-night crowd outside the Raven's Nest, knocking a drinker's pint sideways without breaking stride. "Metropolitan Police! Stop!" He didn't stop. They never did. He was slight, dark-haired, fast in the way of people who'd spent their lives running from things. She'd clocked him twenty minutes ago outside a pawnshop on Brewer Street, passing a wrapped bundle to a man whose face she'd last seen in a case file stamped CLOSED — the same file that still sat in her desk drawer, three years old, DS Morris's handwriting on the evidence log. She'd moved in. The bundle man had vanished into the crowd. The courier had bolted. Her boots hammered the wet stone. "Unit two-seven, this is DI Quinn, foot pursuit, heading south through Soho, suspect male, twenties, grey hooded jacket—" Static. She glanced at the radio. The display had gone dark. She dropped it and ran faster. The suspect cut left into an alley, vaulting a spill of bin bags. Quinn took the corner wide, shoulder grazing brick, and nearly lost him when her heel skidded on something slick. She caught herself on a drainpipe and pushed off. The alley stank of grease and rainwater and something underneath it — copper, or close to copper. She knew that smell. She'd smelled it in the stairwell where they'd found Morris. "Give it up!" Her voice came out raw. "You're making it worse!" He looked back once. In the slice of light from a doorway, she saw his face — young, frightened, and strange. His eyes caught the light wrong. Too bright. Like a cat's. Then he was gone again, out the alley's far end, across a street empty of traffic, down a set of steps she didn't recognise. Quinn reached the top of the steps and stopped. They descended into the earth beneath Camden's edge — iron railings cold under her hand, tiles going from municipal white to something older, Victorian green, cracked and weeping moisture. A station. Abandoned, by the look of the boarded ticket window above, except the boards had been pried apart and warm light bled up from below. No train sounds. No announcements. Just a low murmur, like a crowd holding its breath. Her watch read 11:47. Her radio was dead weight at her shoulder. Her phone — she pulled it out — showed no signal at all, though she stood barely five metres underground. The suspect's footsteps echoed somewhere below, unhurried now. He knew he'd reached safety. That was what frightened her. Quinn had eighteen years on the force. She'd gone into flats where men waited with knives, into a burning squat off the Old Kent Road, into the dark after worse things than this boy. But she stood at the top of those steps with every instinct she owned pulling in two directions, because the last time she'd followed a suspect somewhere she didn't understand, Morris had gone in ahead of her, and Morris had not come out the same. Not alive. Not dead either, not in any way the coroner could write down. She looked at the green tiles. She thought of the evidence log. Morris's handwriting, looping and impatient: Item recovered. Origin unknown. "Bugger it," she said, and went down. The stairs opened onto a platform that shouldn't have existed — not like this. Stalls lined both walls where the tracks should have been, cobbled from scaffold poles and tarpaulin and what looked like salvaged church pews. Lanterns hung from hooks, burning with flames that leaned the wrong way, against the draught. The crowd was a hundred people deep, and none of them were quite right. A woman haggling over a tray of teeth had too many joints in her fingers. A man in a butcher's apron turned to watch Quinn pass, and his shadow stayed facing the other way. She kept her stride even, eyes forward, the way she'd walk a hostile estate. Don't stare. Don't flinch. Her hand rested inside her coat, on nothing — she'd never carried a firearm, and a baton felt like a joke down here — but the posture mattered. The suspect was ahead, moving through the crowd without hurry now, grey hood up. He glanced back, saw her on the platform, and his step faltered. Good, she thought. Be surprised. She followed. The market swallowed them. She passed a stall selling stoppered bottles that glowed faintly from inside, another hung with bones on wire — bird bones, she told herself, until she saw the skulls. A child, or something the size of a child, sat cross-legged on the ground selling maps drawn on skin. Quinn's stomach turned over once and settled. She noted faces, exits, the layout. Three tunnels off the platform, two lit, one dark. A staircase at the far end, chained. Professional habit took the notes even while the rest of her mind screamed. The suspect ducked into the left-hand tunnel. She pushed after him, shouldering past a man who smelled of wet soil, and found herself in a narrower passage lit by candles in alcoves. Fewer people here. Her footsteps and his, out of rhythm. "Police!" she called, and the word fell flat, swallowed by the stone. Down here, it meant nothing. She felt it mean nothing. He stopped. Turned. Up close, in the candlelight, he was younger than she'd thought — maybe twenty, hollow-cheeked, and his eyes weren't strange at all now, just terrified. "You shouldn't have followed," he said. Not a threat. Worry. For her. "Hands where I can see them." "You don't get it." He pulled something from his jacket — small, white, carved. A token, bone by the look of it. "Nobody gets down here without one of these. Nobody. The Market lets you in, or it doesn't." His voice cracked. "It let you in. Do you understand what that means? It wanted you to come down." Quinn didn't lower her stance. Behind the boy, the tunnel stretched on, candle flames all bowing at once, as though something had exhaled further in the dark. Ahead of her: a suspect, an arrest, the first living thread in three years of dead ends. Behind her: stairs, rain, a radio that worked, a world with rules she understood. She thought of Morris, standing at another threshold, telling her to wait, just wait, he'd be two minutes. She stepped forward and took the boy's wrist — gentle, firm, the grip she'd used a hundred times — and turned him toward the light. "You're coming with me," she said. "And you're going to tell me everything."
