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 had been falling since six, and by midnight it had worn the shine off Soho. Quinn sat in the unmarked Vauxhall with the engine off and the windows fogging, watching the green neon of the Raven's Nest bleed across the wet pavement. Eleven fifty-three by the worn leather watch on her left wrist. She'd been sitting there since nine, and her left leg had gone to sleep an hour ago, and none of it mattered because the man she'd come for was inside. Tomás Herrera. Twenty-nine. Former NHS paramedic, struck off three years back for reasons sealed tighter than a coffin. The clique's medic, her file said. The soft target. The one who might talk. The door opened under the green sign and Herrera stepped out into the rain, collar up, a canvas bag slung over his shoulder. Quinn was out of the car before he'd taken three steps. "Tomás Herrera." He stopped. Turned. She saw him read her the way soldiers read ground — the coat, the stance, the warrant card half-raised in her hand — and then his warm brown eyes went flat and hard, and he ran. "Oh, for—" Quinn went after him. He was fast. Faster than a man carrying a bag had any right to be. He cut down an alley off Dean Street, kicked through a drift of cardboard, and Quinn followed with the rain needling her close-cropped hair and her shoes skating on the slick stone. Eighteen years of service and she could still run. What she couldn't do was close the gap. He burst out onto the main road, arm already up, and a black cab swung to the kerb like it had been waiting for him all its life. Quinn made the Vauxhall in twelve seconds and took the corner on a horn and a prayer. The cab led her north through the drowned city, brake lights smearing red across her windscreen, wipers slapping time. She didn't call it in. That was the first wrong thing, and she knew it while she did it. A pursuit, no backup, no log — her DI would have her badge on a plate. But Herrera was the thread she'd been pulling for six months, and three years of pulling threads had got her exactly one dead partner and a file marked unexplained, and she was done being patient. The cab dropped him on Camden High Street. Quinn dumped the car on a yellow line and ran. He went down an alley between a shuttered chicken shop and a pawnbroker's, and she followed him into the dark beyond the streetlights, past bins and a sleeping shape under a blanket of plastic, to a dead end that wasn't dead. An arch. White tiles, old and greened with damp, curving down into the earth — a disused Underground entrance, the roundel above it painted out, the ghost of a name still legible if you knew how to look at old things. A man stood in the arch. Too still. Wearing a long coat that the rain didn't seem to touch. Herrera said something she couldn't hear and opened his palm. Something small lay in it. White. The man in the coat looked at it, looked at Herrera, and stepped aside, and there was a door in the tiled wall where Quinn would have sworn there wasn't one, iron-banded, and Herrera went through it and it swung shut behind him with a sound like a bank vault. Quinn stopped at the arch's mouth, breathing hard, rain running down the sharp line of her jaw. The man in the coat regarded her. His eyes were the colour of old pennies. "Market's token only," he said. His voice had gravel in it. "Metropolitan Police." She held up the warrant card. "That man is wanted for questioning." "Police." He said it the way other men said *rats*. Then he tilted his head, and something moved behind his eyes, and he looked at her — really looked, the way you look at a crack in a wall — for three long seconds. "You've got death on you," he said. "Old death. Unpaid." Quinn's hand tightened on the card. Morris, laughing in the passenger seat. Morris, three years cold. "Open the door." "No token, no entry. Them's the rules." He paused. "But the Market moves at moonset, and it likes a novelty, and you — you're a novelty twice over." He reached out, unhurried, and pulled the iron door open, and warm air breathed up out of the ground smelling of candle wax and copper and wet fur. "Go on then, Detective. Down the stairs. Mind you don't sell anything you can't afford to lose." Every instinct she'd honed in eighteen years told her to step back into the rain, get in the car, drive home, write it up, forget it. She went down. The stairs spiralled. Old tiles gave way to older brick. The sounds reached her before the light did — a murmur like a church service, like a trading floor, like nothing she'd ever heard — and then the stairwell opened onto a platform, and Quinn stopped with her hand on the wall and understood, for the first time in her life, that she had no frame of reference for what she was seeing. The station ran long and vaulted, lit by lanterns that burned without smoke. Stalls lined the platform edge where the tracks should have been — the tracks *were* there, she saw, but furred over with something dark and soft that might have been moss and might have been fur. A woman with silver hair was selling jars of light, actual light, cupped like fireflies. A man in a butcher's apron had teeth laid out on velvet, sorted by size. Someone was auctioning a bottle, and the auctioneer kept saying *last Tuesday, who'll give me last Tuesday*, and the crowd laughed, and Quinn's radio hissed in her ear and said a single word in a voice she knew better than her own, and she ripped the earpiece out and stood there with her heart slamming. *Morris's voice. It had said her name in Morris's voice.* She looked at her watch. The second hand had stopped at twelve-seventeen. Performance, she told herself. A rave. A film set. Theatre kids with too much funding. She said it to herself the way you repeat a prayer, and it held for exactly as long as it took a stall-keeper ten feet away to turn his head and look at her with eyes that were all pupil, no white, and smile with more teeth than the butcher had on his velvet. Then she saw Herrera. He was at a stall near the far tunnel, the canvas bag open, handing something over — a vial, dark glass — and the Saint Christopher medallion swung at his throat as he leaned, and his sleeve rode up and she saw the scar along his left forearm, pale against olive skin. Quinn crossed the platform through the crowd, through smells of myrrh and rain and rotting oranges, and put her hand on his arm. "Tomás Herrera. You're coming with me." He went white. Not angry-white. Afraid-white. His eyes flicked past her, to the stalls, to the crowd, and she watched him do the maths and hate the answer. "Detective Quinn." His voice was low, urgent, Seville still in the vowels. "You have no idea what you've walked into. You need to leave. *Now.*" "You're going to explain the vial, the door, and whatever the hell this place is." "This place is the Veil Market, and it is not for you, and every second you stand here it *notices* you more." He closed his hand over hers where it gripped his arm — gently, like a medic calming a patient — and leaned in. "You lost your partner. Three years ago. You still don't know what took him, and they never told you because they couldn't. I am begging you — go home before you find out the way he did." The platform went quiet. Not all at once. It spread, stall by stall, lanterns dimming in a slow wave from the far tunnel, until the only light left nearby was the jar-light at the silver-haired woman's table, and she was looking past Quinn with an expression of profound professional regret, the way a publican looks at a fight that's already started. Something stood at the mouth of the far tunnel. Tall. Patient. It had been standing there, Quinn realised, for some time. "Stairs," Herrera said. "Behind you. Don't run until I say." He let go of her arm. "*Run.*" She ran. Pride went with her, screaming that she didn't run from suspects, and instinct rode over the top of it like a wave. The crowd parted for her — that was the worst part, the way they *parted*, amused, interested, a man reaching out almost idly as if to touch her sleeve and being slapped away by the silver-haired woman — and then her shoes hit the stairs and she took them three at a time, up and up through brick and tile into the cold. The iron door slammed behind her. She spun on the wet pavement, and there was no door. There was a bricked arch, green with years of damp, and the rain, and the man in the long coat was gone. Quinn stood in the alley with her fists clenched until her breathing came back. Then she felt it — something in her coat pocket that hadn't been there before. Small. Smooth. A sliver of bone, carved with a mark she didn't know, warm as if from someone's palm. Her watch ticked. She looked down. Twelve-seventeen, and the second hand moving again, and forty minutes of her life simply absent from the dial. She closed her fist around the token and walked back to the car through the rain, and all the way home, through the dead hours, one thought turned over and over with the wipers: the Market moved at moonset. It would be somewhere else tomorrow. She was going to find it. And this time she'd be invited.
