The rain came down in sheets that turned Soho's neon into smears of colour on the pavement. Quinn's boots hammered the wet stone, each stride closing the distance to the figure ahead of her. "Police! Stop!" The man didn't stop. They never did. He wore a grey hood, soaked through to a darker shade, and he moved like someone who knew these alleys better than the back of his own hands. He cut left off Brewer Street, down a passage barely wide enough for two people, and Quinn followed without breaking stride. Her shoulder clipped brick. She kept running. "You're making this worse!" she shouted after him. "We only want to talk!" A lie, and they both knew it. She had a warrant in her jacket pocket, laminated against the weather, with his face printed above a charge of conspiracy. The same face she'd seen twice before, leaving the Raven's Nest with people she'd been watching for six weeks. The green neon of Silas' bar still burned in her peripheral vision even here, three streets away, like an afterimage. The man vaulted a wheelie bin. She went through it instead, sending it clattering, rubbish fanning across the wet ground. Her radio crackled at her shoulder. "Quinn, what's your twenty? Over." She thumbed it without slowing. "On foot, pursuit, heading south through the alleys off Wardour. Male, grey hood, five-ten. I need units on the far side of—" The man dropped out of sight. Quinn skidded to a halt at the mouth of a stairwell, her boots slipping on the slick pavement. A gap in the row of shopfronts. A descending staircase she'd walked past a hundred times without noticing, squeezed between a shuttered kebab shop and a boarded-up pawnbroker's. No sign. Just blackness going down, and a worn handrail slick with rain. She checked her watch out of habit. 11:47. The leather strap hung loose where the third hole had worn through. "Control, suspect's gone underground. Some kind of stairwell between—" She read the street numbers. "Between 34 and 36 Beak Street. No visible signage." Static. Then: "Say again, Quinn? There's nothing between those numbers on our map." She stared down into the dark. Somewhere below, footsteps echoed, quick and unhurried both at once, the rhythm of a man who believed he'd already escaped. "He went down. I'm going after him." "Quinn, wait for backup. Quinn, do you copy?" She copied. She also remembered Morris, three years dead, and how they'd found him in a place that officially didn't exist, and how the report had said things she still couldn't square with the world. She drew her torch and her baton and went down the stairs. The rain's hiss faded behind her, replaced by a hum. Electrical, maybe. Or something else that lived in her teeth. The stairwell went deeper than any cellar had a right to go, curving, the walls shifting from brick to old yellow tile. Underground station tile. She knew that tile. Her father had been a Tube driver for thirty years. The stairs ended at a platform that shouldn't exist. Quinn stood at the threshold, torch raised, and forgot, for a moment, that she was chasing anyone. The platform stretched away in both directions, lit by lanterns strung on wire where the fluorescent tubes used to hang. Camden, she realised. This had to be one of the sealed branches beneath Camden, the ones closed before she was born. Except nobody had told the people here that it was closed. Stalls lined the walls, dozens of them, built from crates and salvaged doors and lengths of velvet. Candles burned in jars. The air smelled of damp stone and incense and something else, something sharp and herbal that made the back of her throat tighten. People filled the platform. Too many people for midnight, for a place that wasn't on any map. They browsed. They haggled. A woman with grey skin—grey, not pale, grey like wet cement—counted coins into a vendor's palm. A man in a three-piece suit examined a row of jars containing things that moved. Quinn lowered her torch. There, twenty metres down the platform, grey hood still up, moving through the crowd with the ease of a regular. Her suspect. He paused at a stall, said something to the vendor, kept walking. Her radio hissed. "Quinn, report. Quinn—" She killed the volume. Down here, the signal would be useless anyway. A man stepped into her path. Broad, watchful, with the stillness of hired security. He wore no uniform, but he didn't need one. "You lost, love?" "Metropolitan Police." She held up her warrant card. "I'm pursuing a suspect. Grey hood, came through not thirty seconds ahead of me." The man didn't look at the card. He looked at her face, then past her, up the stairs she'd descended, as if measuring something. "Entry's by token," he said. "You don't have a token." "I have a warrant." "That'll matter topside. Down here it matters less." He wasn't threatening her. That unsettled her more than a threat would have. "You've got two choices, Detective. Turn around and forget the stairs. Or walk in uninvited, in which case anything that happens is on you. House rules." "House rules." Her jaw tightened. "And whose house is this?" "It moves." He shrugged. "Full moon, it'll be somewhere else. You'd best decide quick." She looked past him. Her suspect had reached the far end of the platform, where the tunnel mouth gaped black. He glanced back. Even at this distance, she felt him see her. Then he stepped into the dark of the tunnel, and the crowd swallowed the space where he'd been. Eighteen years of service. Decorated. Commended twice. She had protocols for everything—armed suspects, hostage situations, bombs. Nothing in the manual covered a market in a ghost station where the doorman knew her rank before she said it and the patrons weren't entirely people. Morris had gone into a place like this alone. She'd always believed that. The case file called it a disused warehouse. The file was written by someone who hadn't seen the place, or someone who had and chose to lie. "Detective." The bouncer's voice had softened a fraction. "I've seen your sort come down before. The ones who turn back, we never see again. That's not a threat. That's just how it works." "And the ones who don't turn back?" He said nothing. Quinn thought about the warrant in her pocket, the hours of surveillance, the photographs pinned to the incident room board. The clique. Their meetings behind the bookshelf at the Raven's Nest. The paramedic who wasn't a paramedic anymore, patching wounds no hospital report ever recorded. Six weeks of work, and it all funnelled down to this: a threshold, a choice, a man in a grey hood vanishing into a tunnel. She clicked her torch back on. "I'm armed, and I'm going in after a suspect. If you want to obstruct a police investigation, you'll do it knowing exactly what that means." "Down here," the bouncer said, stepping aside, "it means nothing at all. That's the point." He studied her a moment longer, then reached into his coat and pressed something small and cold into her free hand. "You'll draw less attention holding this. Don't spend it." She looked down. A token, carved from bone, worn smooth at the edges. A face stared up from it. Not a face she recognised. Not a face she wanted to recognise. Quinn pocketed her baton, kept the torch low and angled at the ground, and walked into the market. The crowd parted around her without quite looking at her. She kept her eyes forward, her stride even, the way she'd learned to walk through prison corridors: like she belonged, like nothing here could touch her. Stalls passed on either side. Books bound in something that wasn't leather. Bottles that glowed faintly. A cage, small, ornate, with something inside that sang in a minor key. She did not stop. She did not stare. Ahead, the tunnel mouth waited, and somewhere inside it, her suspect was still moving, unhurried, certain she wouldn't follow. Quinn tightened her grip on the torch and walked into the dark.
