The rain had been falling since four that afternoon, and by eleven it had stopped being weather and become a condition of the city, something Soho had simply agreed to. Quinn stood in the doorway of a shuttered dry cleaner's on Bateman Street with her collar up and her hands empty, watching the green neon of the Raven's Nest bleed into the puddles thirty yards down the road. The sign buzzed. Every few seconds it stuttered, and for half a heartbeat the whole street went ordinary again. Eighteen years on the job had taught her the difference between a hunch and a hypothesis. This was a hypothesis. Four bodies in fourteen months, all of them with the same absence in the tox screens — not a poison, not a drug, just a hole where the chemistry should have been. Three of the four had been in the Raven's Nest within the last week of their lives. And every time she pulled the door and asked her questions, the barman polished a glass and the regulars looked at their hands and she left with less than she'd walked in with. She had stopped asking questions. Now she just watched. At 11:14 the door opened and a man came out under a folded newspaper he hadn't bothered to unfold, and Quinn's pulse changed gear. Tomás Herrera. Twenty-nine, Seville-born, struck off the paramedic register two years ago for what the HCPC report had called *administration of unauthorised substances to unidentified patients*. She'd read that report eleven times. *Unidentified patients.* Four words doing an enormous amount of work. He'd cut his hair since the photograph. He moved like a man carrying something valuable in his ribs — quick, light, checking the street in the reflection of a parked Škoda's window rather than turning his head. Good instincts. Not good enough. Quinn let him get to the corner before she stepped out of the doorway. He made her at Frith Street. She saw the exact moment it happened: his shoulders dropped an inch, the tell of a man deciding, and then he was gone round the corner at a dead sprint with the newspaper coming apart in the air behind him like something shot down. "Herrera!" she shouted, and then didn't waste any more breath on it. The chase went the way they always went, which was to say badly and fast. He was eleven years younger and he knew the ground. He took the alley behind the Portuguese place, vaulted a stack of bin bags that split under his trailing foot and put a slick of coffee grounds and cabbage across the cobbles for her to find. She found it. Her heel went out and she took the wall with her shoulder and kept going, breath sawing, the radio in her jacket pocket knocking against her hip like a second heartbeat. She didn't reach for it. That was the thing she would have to write up later, or not write up: she didn't call it in. Because she knew where he was going, and she knew what she'd say if she called, and she knew what Control would say back, and none of it would include the word *market*. Shaftesbury Avenue was a river of red brake lights. He went through it at an angle, a cab horn ripping the air, a cyclist screaming something wonderful and obscene. Quinn followed in the gap he'd made, one palm slapping the bonnet of a Prius, and the rain came down her collar and got a grip on her spine. She lost him twice. Once at Cambridge Circus, where the crowd outside the theatre had spilled out under a sea of umbrellas, and she stood in the middle of it turning like a compass needle until she caught the flash of him — pale blue shirt, wrong for the weather — going down the steps to the Tube. Then again on the northbound platform, where the tunnel wind smelled like hot iron and old paper and the boards said *2 min*, and she thought: *He's on a train, he's gone, I've lost him.* But he hadn't got on a train. He'd walked to the far end of the platform where the tiling turned to bare brick and the cameras stopped, and when the train came in he stood in its noise and its shadow, and when it left he wasn't there. Quinn went after him. Down the black slope at the platform's end, past a sign that said *NO ENTRY — AUTHORISED PERSONNEL* in a typeface from another century, and into the dark. Her torch found the wall. Cable runs, furred with dust that hadn't been disturbed in decades, except along one clean stripe at shoulder height where hands had touched, hundreds of hands, thousands, wearing the grime away to a shine like a church rail. She followed the shine. Two hundred yards. Three. The tunnel gave onto a curve of platform that shouldn't have existed, with tilework the colour of nicotine and a name in the mosaic she'd never heard of, half of it gone. And light. Not torchlight. Warm, moving, low — lantern light, and the flicker of something bluer, and under it a sound she recognised instantly and had no category for: the sound of a market. Voices haggling. Something being ground in a mortar. Laughter. A stringed instrument, badly tuned, playing something in a mode that made her teeth ache. Tomás Herrera was thirty feet away with his hands on his knees, chest heaving, looking back at her. Between them stood a man in a bus conductor's coat that had been out of service since the sixties, holding out one flat palm. "Token," the man said. Herrera straightened. He was still breathing hard, and his hand went to his chest, and Quinn saw the little silver medallion he wore come up out of his shirt as he clutched it — Saint Christopher, patron of travellers, of people going somewhere they might not come back from. He looked at her with an expression she was not prepared for. Not triumph. Not fear, exactly. Pity. "Don't," he said. His accent came out thicker with the effort of breathing. "Detective. Please. Go back up the stairs." "You ran." "Yes." A laugh with nothing in it. "You have that face. The face people have before they arrest me." "Four dead," Quinn said. "Yulia Marchenko. Danny Oduya. The man in the canal we never named. Sarah Kettle, twenty-three years old, found in a stairwell in Peckham with her blood chemistry looking like someone had *edited* it." Her voice was doing something she didn't authorise. She let it. "You were the last person to see two of them alive." "I was the last person to *try*," he said. The conductor's palm hadn't moved. "Token," he said again, patient as a turnstile. Herrera reached into his jacket and produced something small and pale, and Quinn's torch caught it: a sliver of bone, no bigger than a domino, drilled through at one end and worn smooth. He pressed it into the flat palm. The conductor stepped aside like a door opening. And Quinn stood in the dark at the mouth of the tunnel with her warrant card in her pocket and eighteen years of decorated service behind her and every single one of them useless, because she had no token, no warrant that meant anything past that man's outstretched hand, and no radio signal a hundred feet under Camden. Three years ago she had followed Morris down a set of stairs very like these. He had gone through a door and she had stopped to answer her phone — six seconds, eight at most — and when she went through after him there had been nothing on the other side but a room with no other exit and a smell like a struck match, and she had spent thirty-six months building a version of the world where that made sense. The version had holes in it. She had lived in it anyway, the way you live in a house with a bad roof. Herrera was walking away into the lantern light. Past him, the platform opened out, and she could see stalls — actual stalls, trestles and canvas — and jars, and something in one of the jars turning to look at her. *Go back up the stairs*, he'd said. Up the stairs was the northbound platform and a Circle line map and a Pret at street level that would be open by six, and the case file with four names in it that would sit in a drawer until it was somebody else's, and Morris's widow at Christmas asking, again, gently, *but what actually happened, Harlow?* Quinn wiped the rain out of her eyes with the back of her wrist. Her watch strap was soaked through; the leather had gone dark and heavy, the way it did. "Herrera," she called. He stopped. Turned. "Whatever's down there." Her voice sounded very level, which was a lie her body was telling for her. "Is it going to kill me?" He considered the question with an honesty she hadn't expected, and that frightened her more than a threat would have. "Not if you stay close," he said. "Not if you don't buy anything. And not if you don't tell anyone your name." The conductor's hand came out again, flat and pale, waiting. Quinn stepped over the line where the torchlight ended.
