The rain had been falling since Soho, and by Camden it had stopped pretending to be anything but a deluge. Harlow Quinn stood in the doorway of a shuttered kebab shop on Chalk Farm Road and watched the man across the street through a curtain of water sheeting off the awning. Forty minutes she'd been on him. Out the door of the Raven's Nest under that sickly green neon, north on foot, then the Northern line, and she'd stood two carriages down and watched his reflection in the black glass the whole way. Now he was here, loitering outside a locked gate beside a boarded-up entrance to nothing, checking his phone like a man with an appointment. Tomás Herrera. Twenty-nine. Former paramedic, struck off by the Health and Care Professions Council eighteen months ago for "administering unapproved substances to patients without consent or clinical justification." The file was thin in the places that mattered. The patients, for instance. Four of them, and not one had a name the NHS could verify. Quinn checked her watch. The leather strap was dark with rain, the face fogged at the edges. 11:52. He'd been at the Nest for two hours. So had half the people she'd been circling for six months, the ones who drank in Silas's bar and went in through the back and didn't come out the front. Three disappearances in Westminster since spring. Two bodies that the coroner had signed off with a shrug. Every thread she pulled came back to that bar and its maps and its photographs of dead Londoners staring out of the walls. And Herrera was the one who patched them up afterward. She was sure of it. Across the street, he looked up. Not at her. Past her, at the sky, like he was checking the weather. Then his head came down and turned, and for one long second his eyes found the kebab shop doorway, and Quinn knew she'd been made. He ran. She was already moving. Eighteen years had taught her the first step mattered more than the fastest one. She came off the kerb into ankle-deep water in the gutter, and a night bus blared at her and threw up a wall of spray, and she went round the back of it and saw him cutting left down an alley between a vintage shop and a shuttered market stall. "Police! Tomás Herrera, stop!" He didn't stop. They never did. But he looked back, and that cost him half a step on the wet cobbles. The alley stank of wet cardboard and old frying oil. Quinn's shoes skidded, found purchase. Ahead of her Herrera vaulted a stack of pallets, one hand braced on top, and she saw the pale line of the scar along his left forearm where his sleeve had ridden up. Knife wound, according to an A&E record from Whitechapel. He'd treated himself and discharged himself before anyone could ask how. She took the pallets at a scramble. Her knee cracked against a slat, and she swallowed the pain and kept going. The alley spat them out onto a service road behind the old railway arches. Brick vaulting overhead, water pouring off the edges in ropes. Herrera sprinted beneath them, and his footfalls echoed back doubled, tripled, until it sounded like a crowd was running. Quinn followed the real ones. She'd always been able to tell. He darted right, towards a chain-link fence she'd walked past a dozen times in daylight and never looked at twice. Behind it was a squat brick structure with the ghost of a roundel painted over in grey municipal paint. A disused station entrance. There were dozens across London, sealed up when the lines were rerouted, forgotten by everyone but trainspotters and urban explorers. The fence had a gap. Herrera went through it sideways without breaking stride, as though he'd done it a hundred times. Quinn hit the fence a second later and felt the cut ends of the wire snag her coat. She tore free. Beyond the fence, a steel door that should have been welded shut stood ajar, and a thin, amber light leaked from the crack like something alive. Herrera hauled it wider and plunged through. She reached it three strides behind him and caught the door before it closed. Stairs went down, steep and tiled, the old cream-and-maroon of Edwardian stations, cracked and stained with a century of damp. The light came from below. So did the noise, and it wasn't the dripping silence of an abandoned tunnel. It was voices. Hundreds of them. Music, something reedy and wrong, in no key she recognised. The smell hit her next, woodsmoke and spice and under it something sharp and chemical that clawed at the back of her throat. She knew that smell. It stopped her on the top step as surely as a hand on her chest. Three years ago, in a flat above a laundrette in Deptford, she had smelled exactly this. She had kicked in the door with Morris beside her. She remembered the heat of the room, the strange sweet-burnt air, Morris saying *Harlow, get back*, in a voice she had never heard him use. And then the light going out, and when it came back on he was gone. Not dead. Not injured. Gone. They'd never found so much as a shoe. The official report said he had left through a rear window. There was no rear window. Quinn's heart was going hard, and not from the running. Below, Herrera's footsteps clattered down the stairs. She shook herself and followed. The stairwell turned once, twice. The tiles grew older as she went, and then they weren't tiles at all but something carved, symbols scratched into the plaster in no alphabet she'd ever seen. The amber light brightened. At the bottom was a long passage leading to what must once have been the ticket hall, and across its mouth stood an iron turnstile of the old kind, waist-high, with a figure beside it. Herrera reached the turnstile and slapped something into a slot on top. Quinn lunged the last few feet and closed her hand on his sleeve. He twisted. For a moment they were face to face, close enough that she could see the rain dripping from his dark curls, the gold Saint Christopher medallion swinging free of his collar. His warm brown eyes weren't frightened, not quite. They were something closer to pity. "Detective," he said, breathless, his accent softening the edges of the word. "You don't want to come in here. Please. Go home." "Where's Morris?" It came out of her before she could stop it. She hadn't meant to say it. She hadn't said his name aloud in a year. Something shifted in Herrera's face. Recognition, maybe. Or just surprise. "I don't know who that is," he said. And then, quieter: "But if he came down here, I'm sorry." He wrenched his arm, and her wet grip slid. He was through the turnstile and gone into the amber haze before she could grab again. The iron arms clanked back into place behind him. Quinn slammed against the bar. It didn't move. The figure beside the turnstile turned its head. It was tall and hooded, and it had been perfectly still until now, so still she'd taken it for a statue. Beneath the hood she saw only a jaw, grey and finely lined as old paper, and a mouth that didn't open when it spoke. "Token." The voice was dry. It came from everywhere at once. "Metropolitan Police." She held up her warrant card with a hand that she was relieved to find steady. "I'm in pursuit of a suspect. Open this gate." The hooded thing regarded the card for a long moment. Then it looked back at her. "Token," it said again, with no more inflection than before. Beyond the turnstile, the old ticket hall opened into something vast. The platform and tracks were gone beneath a sprawl of stalls lit by lanterns and jars of cold, floating light. Stalls selling glass vials that pulsed like heartbeats. Stalls hung with dried things she didn't want to name. A woman with too-long fingers weighed out silver dust on a scale. Two men argued over a cage draped in black silk, and whatever was in it was singing. Everywhere, people moved and haggled and laughed, and not all of them walked the way people were supposed to. She had eighteen years of service and a chest of commendations. She had pulled bodies out of the Thames and talked a man off a parapet on Waterloo Bridge. She had never once in her life felt so thoroughly that she was standing on the wrong side of a line. She looked down. On the floor at her feet, half-submerged in a puddle of rainwater she'd dragged in herself, lay a small, pale object. It must have come free when she'd grabbed Herrera's sleeve. She crouched and picked it up. A disc of bone, no bigger than a fifty-pence piece, carved with one of those symbols from the stairwell. It was warm. Warmer than it should have been, like it had been held in a closed fist for hours. She turned it over in her fingers. She thought about the radio in her pocket, dead since the second landing. She thought about the protocol she knew by heart, the one that said *withdraw, report, request backup.* She thought about how that report would read to her superintendent, and how it would read to the psychologist he'd send her to afterwards. She thought about Morris saying *Harlow, get back.* She hadn't gotten back. She'd gone in after him, and she'd been too slow, and the light had gone out. The hooded figure watched her without eyes. Beyond it, far down the crowded platform, she caught a flash of dark curls moving away through the throng, not quite running now. Herrera looked back once. He didn't look afraid for himself. He looked afraid for her. Quinn stood. She squared her shoulders, the old parade-ground habit, and wiped the rain from her face with the back of her wrist. Her watch read 11:58. Two minutes to midnight, in a place where she doubted midnight meant anything at all. She set the bone token into the slot. The turnstile turned.
