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 abandoned Tube station beneath Camden smelled of rust and something older, something that made the hair on Detective Harlow Quinn's arms rise without her permission. She ducked under the crime scene tape that Constable Reyes had strung across the top of the disused escalator, her torch beam cutting through dust motes that hung in the air like they'd forgotten how to fall. "Careful on the stairs, ma'am," Reyes called up from below. "Been closed since '87. Some of the boards are rotten." Quinn descended anyway, her boots finding sure purchase on eighteen years of instinct. The platform opened up below her, tiled in faded maroon and cream, the old signage for CAMDEN TOWN still visible beneath a skin of grime. Emergency lighting had been rigged, throwing harsh white pools across the scene, and in the center of one of those pools lay the body. A man, mid-thirties by the look of him, dressed in what had once been an expensive suit. He lay on his back with his arms flung wide, and his face wore an expression Quinn had seen only twice before in her career — not fear, exactly, but something closer to profound confusion, as if he'd died asking a question nobody had bothered to answer. "Detective Sergeant Patel," said the man crouching beside the body, standing as she approached. He was younger than her, eager in the way new DSs always were, still convinced the job made sense if you looked hard enough. "Thanks for coming down. This one's a bit outside the box." "Aren't they always, these days." Quinn crouched where Patel had been, careful not to touch the tiled floor with her knees. "Talk me through it." "Transport Police found him about two hours ago. No ID on him, no phone, nothing. Cause of death looks like cardiac arrest — no visible wounds, no blood, nothing to suggest violence." Patel gestured at the body with the confidence of a man who'd already written his report in his head. "My guess? Heart attack. He wandered down here — kids do it all the time, urban explorers, that sort of thing — got himself lost in the dark, panicked, and his ticker gave out. We'll get a proper cause of death from the pathologist, but I'd put money on natural causes complicated by fright." Quinn said nothing. She let her torch travel down the length of the body, slow and deliberate, the way her old training officer had taught her — *look twice before you think once, Quinn, the ground doesn't lie but it does whisper.* The man's shoes were unmarked by dust. That was the first wrongness. If he'd wandered down here in the dark, stumbling and panicking as Patel suggested, his shoes should have been scuffed, dragged, the leather torn from contact with the rough concrete beyond the platform's edge. Instead they gleamed, barely touched, as though he'd been set down gently rather than having walked here at all. "Patel. Come look at this." He crouched again, following the line of her torch to the shoes, then up to the man's hands. The fingers were curled inward, not in the loose slackness of a heart attack victim but with tension, like he'd been gripping something and it had been pulled away. "His hands," Quinn said. "Rigor," Patel offered, though his voice had lost some of its certainty. "Too early for full rigor, and it's not uniform. Look — the left hand's curled tighter than the right." She reached into her coat pocket for a pair of gloves, snapped them on, and gently lifted the man's left wrist. Beneath his cuff, just visible, was a mark — not a bruise, not exactly, but a discoloration in the shape of concentric rings, like something had been pressed there and left its signature in the skin itself. "That's not a struggle mark," Patel said slowly. "What is that?" "I don't know yet." Quinn let the wrist down carefully and turned her torch on the floor around the body. There — faint, but there, if you knew to look for it — a scorch pattern in the dust, radiating outward from where the man had fallen. Not the black smear of fire, but something paler, like the dust itself had been repelled rather than burned. She thought of DS Morris. Three years, and she still thought of him every time the world tilted half an inch away from the version everyone else agreed to see. He'd have crouched right where she was crouching now, and he'd have made some dry joke about the Underground finally living up to its name, and then he would have died two weeks later in a warehouse in Deptford with the same look on his face this man wore now — that terrible, unanswered question — and nobody, not the pathologist, not the coroner, not the eleven detectives who'd worked the case after her, had ever explained it to her satisfaction. "Ma'am?" Patel was watching her. "You've gone somewhere." "Have I." She stood, brushing nonexistent dust from her knees out of habit. "Patel, I want SOCO back down here before anyone touches this scene again. I want that dust pattern photographed and I want it photographed properly, not the usual wide shots — get someone with a macro lens if you have to borrow one from the press office." "You think it's not natural causes." "I think," Quinn said carefully, because she had learned in three years exactly how much of her thinking she could afford to say aloud without being quietly reassigned to a desk somewhere, "that a man does not walk into a derelict Tube station in unmarked shoes, die of fright with his hand curled around something that isn't there anymore, and leave a mark on the dust that looks like nothing I've seen a human body do in eighteen years of looking at bodies." Patel opened his mouth, then closed it again. Somewhere above them, a train rumbled through on the still-active line, and the sound rolled down through the old tunnels like a held breath finally released. Quinn crouched once more, close to the dead man's ear, as though she might ask him the question he'd died asking. The verdigris-green tang of old copper hung faint in the air, threading beneath the rust and dust — a smell she was beginning, against every rational instinct she owned, to recognize. She did not yet have a name for what had killed this man. But she had a feeling, cold and precise as a blade laid flat against her spine, that she was getting closer to understanding what had killed Morris. And that feeling frightened her far more than the body did.
