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 going since four, and by eleven it had stopped being weather and become a condition of the world. Quinn stood in the doorway of a shuttered barber's shop on Bateman Street with her collar up and water finding the gap anyway, running a cold line down her spine, and watched the green neon of the Raven's Nest bleed across the wet pavement. Eighteen years. She'd spent a good portion of them standing in doorways. The sign flickered — it always flickered, some fault nobody had bothered to fix, or nobody wanted to — and the light on the road went from green to nothing to green again, like a pulse. Quinn had counted forty-one people in since nine. Twelve out. That was wrong on its own. She'd looked at the floor plan from the fire safety records, and the Raven's Nest did not have room for twenty-nine extra bodies unless they were stacked. At 11:14 the door opened and Tomás Herrera came out. She knew him from the file photograph, taken back when he'd still had an NHS lanyard and a job: olive-skinned, twenty-nine years old, short dark curls now flattened black by the rain. Five ten. Canvas satchel over one shoulder, held against his ribs the way you hold something you'd run for. Herrera, Tomás. Struck off the register eighteen months ago for administering unauthorised treatments. She'd read the tribunal transcript four times and it still read like a document with pages missing. *The patient's presentation was not consistent with human physiology.* That was the phrase. Nobody on the panel had asked him what he meant by it. That was the part that kept Quinn up. He came down the step, glanced left, and started walking east. Quinn gave him twelve seconds, then followed. He was good, but he wasn't police-good. He checked reflections in the dark glass of a closed patisserie. He crossed against the light on Charing Cross Road to see who crossed with him — Quinn didn't, she stayed on her side and let the buses screen her — and he doubled back once through the arcade off Cambridge Circus, which would have worked on a single tail. She'd worked with Morris for six years and they'd had a hundred ways of eating a doubling-back. She used one now, out of muscle memory, and felt his absence like a tooth pulled. At Tottenham Court Road he took the Northern Line north. She sat two carriages down and watched him through the connecting windows, a smeared shape in the fluorescence, his hand going up again and again to touch something at his throat. She'd seen it in the photo: a Saint Christopher medallion, cheap silver, worn to a shine. Patron saint of travellers. Patron saint of people who don't expect to arrive. He got off at Camden Town and she was thirty feet behind him on the escalator and he made her. She never knew how. Maybe the reflection in the ad-panel glass, maybe just the animal part of him counting the same footsteps too long. But his shoulders changed — she saw the exact moment, the small tightening — and then he was running. "Police!" she shouted, because you had to, and the word did nothing at all. Out through the ticket hall, out into the noise. Camden High Street at half eleven on a wet Thursday: kebab shop steam, spilled bass from a basement club, the gutters roaring like small rivers, drunk kids in shirt-sleeves not feeling the cold. Herrera went through them like water through a fence. Quinn went after him. She was forty-one and she ran four mornings a week on the towpath and she was still, at the two-hundred-metre mark, losing. He had youth and he had panic and he knew these streets in a way that couldn't be learned from a map — he took a gap between a skip and a wall that Quinn had to turn her shoulders for, vaulted the low chain outside the market gates, went left where the streetlights ended. "Herrera!" Her voice tore. "Tomás! I only want to talk to you about Morris!" That got him. For half a stride, his head came round, and she saw his face in the sodium wash — warm brown eyes, wide, and something in them that wasn't fear of arrest. It was fear *for* her. She'd seen that look on paramedics before. It was the face they made when they'd already decided you weren't going to make it. Then he was gone down the steps. She came to a stop at the top of them, breathing hard, rain running off her jaw. Water sluiced past her boots and down into the dark. She knew this place. She'd walked past it a hundred times without seeing it. A stairwell behind hoardings on the canal side of the market, the kind of thing you'd assume was Thames Water or the council: STRICTLY NO ACCESS. DEEP EXCAVATION. And below, twelve steps down, an old ox-blood tile arch and the ghost of lettering in the tilework — the disused station, one of the dozens sealed up before the war and forgotten by everyone but urban explorers and the tunnel maintenance crews. Except the gate at the bottom was open, and it was warm. Quinn felt it on her face. Warm air coming up out of the ground, and it carried a smell she had no filing cabinet for: woodsmoke and cardamom and hot metal and, underneath, something like a wet animal. There was light down there. Not the white of work lamps. Amber, and moving, and multiple. And there was sound. That was the thing that stopped her more than the light did. Not a hum, not machinery. Voices. Dozens of them, hundreds maybe, a market's worth, the pitch and roll of haggling — and none of it in any language she could put a name to. Her radio was in her hand. She looked at it. *Control, DS Quinn, requesting urgent assistance, my location is—* And then what. Then some tired sergeant sends two response cars to a sealed Victorian stairwell behind Camden Lock, and they find bricks and rats, because that was what everyone always found, wasn't it. That was what she'd found three years ago on Bermondsey Wall, standing in an empty warehouse with her partner's coat on the floor and his radio still keyed open, screaming static, and nothing, nothing, nothing to write in the report. *DS Morris, last seen —* Twenty-two months of investigation and the coroner's inquest recorded an open verdict, and every senior officer she'd ever respected had looked at her with a particular careful patience, and the patience was worse than the disbelief. She put the radio away. Then she took out the evidence bag. She shouldn't have had it. She'd signed it out of the property store on a pretext eleven months ago and never signed it back. Inside was a token the size of a poker chip, cut from bone — real bone, the lab had said, human, and had refused to be drawn further — with a mark scored into one face that hurt slightly to look at directly. It had been in the inside pocket of Morris's coat. He had never mentioned it. In six years of sitting beside her in cars, eating chips, showing her photos of his daughter's swimming certificates, he had never once mentioned it. Quinn stood in the rain with her thumb on the bone and did the arithmetic she'd been avoiding for three years. Down there was a place with no address, no jurisdiction, no back-up, no exit she could name. She had a warrant card that meant nothing past that arch and a suspect who'd looked at her like she was already a fatality. Everything in eighteen decorated years — everything Morris himself had drilled into her, *never go in blind, Harlow, ever* — said: withdraw, observe, build the case, come back with thirty officers and a plan. But there wasn't going to be a plan. There would never be thirty officers. There would only ever be her, and this stairwell, and the fact that the last time she'd done the correct and careful thing, she'd stood in an empty warehouse and lost him. Water ran off the hoarding above her in a rope. She wiped her face with the heel of her hand, took the token out of the bag, and closed it in her fist so the edge bit her palm. Then she went down the steps, twelve of them, into the warmth. The arch was deeper than it looked — six feet of Victorian brick, sweating — and at the far side a man sat on a stool with a lantern between his knees, a big man, grey-skinned, with a jaw like something built rather than born. He didn't ask her name. He held out one flat hand. Quinn set the bone token in it. He turned it over. He looked at her for a long, unhurried moment, and something behind his eyes rearranged itself. "You're not him," the doorman said. "No," said Quinn. "I'm what's left." He stood aside. And the Veil Market opened up in front of her — the great curved tunnel of a station platform strung with a thousand hanging lamps, stalls crowding the tiled walls all the way into the dark, cages, glass jars, smoke, a woman with too many joints in her fingers weighing something that screamed faintly on a brass scale — and forty feet away, halfway up the platform, Tomás Herrera stopped dead and turned and saw her come through the arch. He crossed himself. Quinn started walking.
