You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The rain came off the Soho rooftops in ropes, and Harlow Quinn had been standing under the dripping awning of a shuttered delicatessen for forty-one minutes when the green neon of the Raven's Nest finally spat a man onto the pavement. She knew him before she knew she knew him. That was the thing about a tail — your body recognized people before your brain caught up. Five-ten, compact, dark curls plastered flat by the downpour, moving like a man who'd rather not be seen. Tomás Herrera. Twenty-nine. Stripped of his NHS licence eight months ago for reasons the General Medical Council had phrased with lawyerly fog. She checked her watch. Twenty past one. Then she stepped out into the rain. She didn't hurry. Hurrying was how you lost them. She kept to the far side of the street, let a black cab drag its spray across her sightline, let a knot of late drinkers stumble between them as cover. He walked east, hands in his jacket, head down, and she counted his paces and matched them, and the rain beat a tattoo on the shoulders of her coat. At the mouth of an alley he stopped. Turned. Looked straight at her. For a moment neither of them moved, and the rain filled the silence the way it fills everything. She saw his face properly then — olive skin, dark eyes, young. Younger than she'd expected. There was a medallion at his throat, a little gold disc on a chain, Saint Christopher, the patron of travellers. He wore it outside his shirt, which meant something, though she couldn't have said what. Then he ran. 'Police!' she shouted, and the word went into the rain and died there. 'Herrera — stop!' He went over a low wall like a man who'd done it before and dropped into the railway cutting beyond, and she went after him without thinking, because thinking was a luxury and eighteen years in the job had trained the luxury out of her. Her palms hit wet brick. Her knees took the landing. Something in her coat pocket cracked — her phone, probably — and she was up and running before she'd finished the thought. Camden by then, or the ragged edge of it, the streets going to lock-ups and rusting gates and shuttered workshops. He was fast but he wasn't fit. She was gaining on him, sixteen years older and eating the distance, and she could hear his breath now, that raw wet rasp of a man at the end of his rope. 'Herrera!' she called again. 'You're going to hurt yourself.' He cut left through a chain-link gap and vanished. She came through it at a sprint and stopped dead. An entrance. A stairwell, mouth open in the ground, ringed by a rusted iron railing, the steps descending into black. It shouldn't have been there. This was a disused section of the Northern line, bricked off in the nineties, fenced, sealed, chained — she'd read the files. But the chain lay coiled on the wet ground like something shed, and a light burned somewhere far below, a soft amber glow that had no business being underground at half one in the morning. She stood at the top of the stairs with the rain running off her jaw and down her collar and did the arithmetic. Backup was twenty minutes out at best. Her radio had been hissing static since the cutting. Her phone was likely dead in her pocket. If she went down there she went alone, without a warrant, without a cross-reference, into a place that wasn't on any map she'd ever signed for. And there was a hard little voice at the back of her skull — the voice that had been there three years ago, in a different stairwell, in a different borough, with Morris standing beside her saying *give it a minute, Harlow, let's wait for the shout* — and Morris had died anyway, and the report into it had been six pages of things that didn't add up. She went down. The steps were wet at the top and dry by the seventh, which was the first thing that felt wrong. The second was the smell. Rain and rot you expected underground. This was worse and better at once — tallow, ozone, something like burnt sugar, something like the inside of a church. At the bottom, a door that wasn't a door. It stood open in a brick arch, and beside it a man sat on a stool with a book in his lap and a bowl at his feet. The bowl was full of bones. Not the small bones. Long bones, knucklebones, a jaw with three teeth left in it, all of them washed clean and pale as chalk, and the man on the stool looked up at her with mild, incurious eyes and said, 'Token.' She held up her warrant card. 'Metropolitan Police. I'm pursuing—' 'Token,' he said again, and didn't blink. She could have shot past him. She was fast; she was armed; she was a detective with eighteen years and a commendation or two. But something about the bowl, about the way the man's eyes didn't move, about the light pouring up out of the doorway behind him, made her hand go to her pocket instead. She came out with a fifty. He looked at it the way you look at a leaf. 'I don't have a token,' she said. 'I don't know what a token is.' The man considered her. Rain dripped from somewhere above, patient as a clock. Then he put his hand into the bowl and drew out a bone — a finger bone, small and yellowed — and held it up between two fingers, and said, 'First one's on the house, Detective.' She took it. It was warm. She went through the door. And the world turned over. She'd expected a squat. A gang hideout. Somewhere with spray-paint and sleeping bags. What she walked into was a city. The ceiling arched away into gloom, ribbed with old tube tunnel brick, and under it the market stretched the length of a platform and then further, deeper, past where the platform ended, into a dark that swallowed sound. Stalls lined both walls, hung with cloth and lit with lamps of a colour she had no word for — amber, but not amber. Something older. Something the eye had to work at. And the crowd. Forty people at least. Sixty. Hoods, furs, stoles. A woman with a child on her hip whose hair hung past her waist. A man so tall his head brushed the stall awnings. They moved between the tables and nobody — nobody — was looking at her. On a trestle to her left, jars. Things in jars. She looked and then she didn't. At the far end, by the light, Tomás Herrera had stopped running. He stood at a table with his back to her, and his jacket was off, and the sleeve of his shirt was rolled up, and she could see the scar on his left forearm, a long pale rope of it running wrist to elbow. He was handing something to the woman behind the table — a package wrapped in cloth, small, and she was handing him something back — coins? cards? — and they were speaking low and fast in a language Harlow didn't know. She started forward. And a hand closed around her elbow, hard enough to bruise. 'You're new,' said a voice at her ear, softly, almost kindly. 'Put your bone in your pocket, Detective. And whatever you do, don't look at the jars twice.' She turned. The person holding her was smiling. Their teeth were wrong. And somewhere behind her, in the dark past the end of the platform, in the place the light didn't reach, a door opened — and it was the same soft amber, and the same tallow smell, and it was the same sound the door had made three years ago when Morris had walked through it and never come back. Harlow Quinn stood very still in the middle of the Veil Market with a dead man's finger bone in her fist and made her decision. She stayed.
