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 stairwell smelled of wet iron and something older — a mineral rot that reminded Quinn of cave floors and forgotten wine cellars. She descended with her torch angled low, the beam catching each tread before her boot found it. Eighteen years on the job had taught her to trust her feet less than her eyes. "Mind the puddle at the bottom, guv." DC Rahim's voice bounced up the tile. "SOCO's still pulling prints off the turnstile." "There are no turnstiles down here," Quinn said. "This station's been sealed since 1959." "That's the thing. There is one now." She reached the landing and stopped. Her torch found the turnstile — brass, not the standard Underground steel, its crossbars etched with something that might have been filigree or might have been writing. Someone had strung police tape around it as though it were furniture rather than an impossibility. Rahim was waiting by the old ticket hall, notebook out, coat too thin for the cold that seeped through the tiles. Behind him, two SOCOs in white coveralls worked in the halo of a portable lamp. On the ground, beneath a thermal blanket, a shape. "Male, late thirties," Rahim said. "No ID. Security at the Camden end found the hoarding pried open around oh-three-hundred and called it in. Looks like a break-in gone bad. He falls, hits his head on the tiles — see the blood pattern — and bleeds out. Straightforward." Quinn crouched beside the blanket. She let her torch walk across the floor first. White tile, mostly. A halo of dark blood, dried now, the edges lacy where it had pooled into the grout. She noted the absence of spatter on the wall behind the body. Noted, too, the way the blood stopped — not smeared, not wiped, but stopped, as though someone had drawn a line across the floor with a ruler and told the blood it could go no further. "Straightforward," she repeated. "Guv?" She lifted the blanket. The man's face was composed, eyes half open, a neat indentation at his temple. No abrasion on the hands. No defensive wounds. His palms were clean enough to eat off. "He fell," Rahim said again, a little less certain. "Show me where." Rahim pointed to a spot three feet to the right of the body. Quinn stood, stepped over the blood, and set her torch on the tile. The beam skimmed the surface, and there — faint, but there — a patch that caught the light differently. She knelt. Ran a gloved finger along it. "He didn't fall," she said. "He was placed." "Ma'am, the impact—" "Look at his trouser cuffs, Rahim. Immaculate. This floor hasn't been mopped in sixty-odd years and there's coal dust thick as cocoa on the edges. He came through somewhere clean and was laid down here. Where are his shoes?" Rahim blinked. "He's wearing—" "Look at them." The man's shoes were polished to a mirror. Not a speck. Not a scuff. Quinn had walked ten paces into this station and her own boots were grey to the laces. She stood again and turned in a slow circle, feeling that old prickle at the back of her neck — the one that had first come to her three years ago in a warehouse in Deptford, five minutes before Morris had stepped around a corner and never stepped back. She'd spent three years telling herself the prickle was instinct, pattern recognition, the subconscious shouting what the conscious hadn't yet named. Most days she believed it. Most days. "DC Rahim," she said. "Who called this in?" "Security guard. Like I said." "Name." He checked his notebook. "A, uh — actually, the desk sergeant didn't get a name. Male caller, said he was Camden Council night security. We've got units trying to reach the contractor now, but the mobile's going to voicemail." "Of course it is." Quinn moved to the far wall, where the tunnel mouth yawned. The air coming out of it was warm. That was wrong. Deep London was cold London; the tunnels beneath Camden were somewhere around fourteen degrees year-round. She held her palm up and felt it — a breath, almost — pushing past her fingers. And there, in the black beyond her torchbeam, the faintest suggestion of light. Not the dull orange of sodium or the white of LED. Something amber. Something that breathed. "Guv?" "How long was the hoarding open before the call came in?" "Hard to say. The contractor checks the site twice a week." "So it could have been open for days." "Yeah, possibly." "And yet the blood on this floor is less than twelve hours old. No rats have been at him. No insects. No animal tracks in the dust around the body." She turned back. "Do you see any dust around the body, Rahim?" He looked. His mouth opened, then closed. There was a clean perimeter around the corpse — maybe a metre and a half, roughly circular — inside which the tile was swept. Outside it, the coal grit of sixty years. Quinn crouched at the boundary and ran her thumb along the line. It felt, very faintly, warm. She didn't mention the warmth to Rahim. She slipped her hand into her coat pocket and her fingers found — out of habit, out of stubbornness — the bone token she'd pulled from Morris's evidence locker eleven months ago and never cataloged. She had no idea what it did. She only knew that since she'd started carrying it, places like this had begun to feel different to her, as though she were standing on the right side of a window she hadn't known existed. "Bag his shoes separately," she said, rising. "I want swabs from the cuffs. And I want a photograph of the floor — every tile within three metres of the body. Grid it." "Guv, with respect, this looks like a straightforward—" "It doesn't look like anything, Rahim. That's the point." She clicked off her torch and let her eyes adjust. The amber suggestion in the tunnel mouth did not go away. If anything, it brightened, the way a pilot light brightens when you stop staring at it. "Somebody staged this for us. The question is why they bothered." She checked the worn leather watch on her left wrist. Four-seventeen. Four hours until full moon set, and something in the tunnel was waiting to see what she'd do. "Get the photographs," she said. "I'm going to have a look down the line." "Alone?" Quinn clicked her torch back on. The beam felt thinner than it had a moment ago, as though the dark were drinking it. "Won't be long," she said, and stepped past the turnstile that shouldn't have been there, into the warm breath of a tunnel that shouldn't have been open, toward a light she was finally ready to admit she could see.
