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 call had come in at 4:47 a.m., patched through three different desks before it reached her, which was how Quinn knew already that nobody wanted to touch this one. *Suspicious death, disused platform, Camden.* By the time she'd parked and shown her badge to the uniform stringing tape across the boarded entrance, the sky had gone the color of a bruise healing, grey-yellow and sick-looking, and she'd had exactly one coffee and no patience. The stairwell down smelled of damp stone and something sweeter underneath, like flowers left too long in their water. Quinn's torch beam cut through dust motes hanging thick in the air, undisturbed, as if the whole station had been sealed since the day it closed. Her boots rang against the tile. Old advertisements peeled from the walls, faded to ghosts of themselves. "Detective." Sergeant Pell was crouched at the platform's edge, latex gloves snapped tight over his knuckles. He'd been with her eleven months, long enough to know she didn't like being told things twice. "Victim's male, thirties, no ID on him. Found by a maintenance crew doing a structural check. They said the door was locked from the inside." "Locked how?" "Deadbolt. Old one, but it works. No other way in or out that we've found." Quinn crouched beside him, careful of her knees, careful of everything. The body lay curled on its side near the platform edge, as though it had simply lain down to sleep and never woken. No blood. No visible wounds. The skin had a strange waxen quality, pulled tight over the cheekbones, and around the eyes there was a faint blue tint that reminded her of frostbite, except the air down here wasn't cold enough for that, not by half. "COD?" she asked. "ME's guessing cardiac. Maybe an aneurysm. We'll know more after the post." "You buy that?" Pell shrugged, the particular shrug of a man who wanted very badly to go home. "People die of natural causes in weird places all the time, Quinn. Bloke could've been trespassing, had a heart attack, and that's that." She didn't answer right away. She was looking at the floor. There, in a wide ring around the body — maybe eight feet across — the dust had been disturbed. Not footprints, not drag marks. It looked almost like the tide had gone out and left a clean sweep of tile behind it, the fine grey silt pushed outward in a perfect circle, thicker at the edges, as if something had breathed it away from the center in a single exhale. "You see this?" she said. Pell leaned over. "Yeah. Cleaning crew, maybe. Or the maintenance guys tracked through it before they called it in." "Maintenance guys who called it in at four in the morning and were, according to your notes, standing at the stairs the whole time too afraid to come down?" She kept her voice level. It was a trick she'd learned a long time ago, keeping the voice level while the rest of her went sharp and cold. "That's not foot traffic, Pell. That's not a mop, either. Look at the pattern. It radiates. Like something pushed it outward from where he's lying." "Could be settling. Air currents. Trains used to run through here." "Trains haven't run through here in thirty years." She straightened up, joints protesting, and turned her torch on the deadbolt Pell had mentioned. It was old, yes, painted over twice, the kind of hardware nobody thought twice about. She examined the frame around it. The wood was intact. No pry marks, no scratches, nothing to suggest force. "So the only way in is locked from inside, no one heard him come in, no one heard him die, and there's not a mark on the body except this." She pointed her light at his throat. Pell frowned and leaned closer. Around the man's collar, faint as a shadow, was a bruise the shape of no hand she'd ever seen — too long, too thin, the fingers if they were fingers curling nearly one and a half times around the neck. "Ligature marks," Pell offered, though he didn't sound convinced of it himself. "With no rope. No wire. No fibers." Quinn crouched again, closer this time, close enough to catch that sweet smell stronger, and beneath it something colder, mineral, like a struck match gone out. "Pell, eighteen years I've worked bodies. I have never seen a bruise shaped like that." "So what, then? What are you saying?" She didn't answer immediately, because the truthful answer was one she still couldn't quite let herself say out loud, not standing in a dead Tube station at five in the morning with a sergeant who thought she'd gone strange these last three years, ever since Morris. Ever since the warehouse fire that had left nothing of her partner but his boots, untouched, sitting neatly by a door that led nowhere. She thought about the boots sometimes. She thought about them now. "I'm saying," she said carefully, "that somebody wants this filed as a heart attack. And I'm saying the floor doesn't lie, even when everything else in this room is telling me to look away." She straightened, glanced once more at the clean, radiating circle in the dust, at the frostbitten blue around the dead man's eyes, at the door with its untouched deadbolt. "There's no explanation for this," Pell said, quieter now, some of the impatience gone out of him. "Not one I can put in a report," Quinn agreed. "Not yet." She clicked off her torch, though the dark down here didn't feel like it wanted to be trusted either. "Bag his hands before the ME gets him. And Pell — get me a list of everyone who's requisitioned this station's blueprints in the last five years. I want to know who else knew about a door that locks from a side no one can reach."
