You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The tape came down easier than Quinn expected, the wind off the canal tugging at it before her hand even touched the stanchion. She ducked under, boots finding the uneven platform tiles slick with algae and standing water. Nobody had run a Tube line through here since the sixties. The tiles still bore the ghost of a station name, letters chipped to illegibility. "Ma'am." DC Whitfield straightened from where he'd been crouched by the body, notebook already out. "Thought you'd want eyes on this one personally." "Why's that." "Because nothing about it makes sense." Quinn crouched at the edge of the small pool of torchlight. The victim lay on his back, arms crossed over his chest like something out of a Victorian funeral parlour, not a struggle. Mid-thirties, decent coat, shoes that cost more than her monthly wage. No blood. No visible wound. "Time of death?" "Doc reckons six hours, give or take. But here's the thing—" Whitfield flipped his notebook open, tapped a page he hadn't written on yet, a nervous habit of his own. "No ID on him. No wallet, no phone, nothing. Except this." He held up an evidence bag. Inside, a small brass disc, roughly the size of a coin, etched with symbols Quinn didn't recognise and didn't like. "Found it in his palm," Whitfield said. "Fingers were curled round it so tight we had to prise them open." "Rigor doesn't usually let you do that." "No, ma'am. It doesn't." Quinn took the bag, turned it under the torch beam. The metal held a faint green bloom, verdigris crawling along the edges like the thing had spent years underwater rather than hours in a dead man's fist. "Any theory?" "Random death, unlucky place to have a heart attack. Bloke wanders down here looking for somewhere quiet to shoot up, coin's a lucky charm or a poker chip, who knows." Whitfield shrugged, the motion too loose for the scene around them. "Camden's full of strange little cults and markets. Probably bought the thing off some stall selling incense and bad advice." "You believe that." "I believe in what I can put in a report, ma'am." Quinn didn't answer. She set the bag down and looked past the body, past the pooled torchlight, toward the tunnel mouth where the platform gave way to dark. The air smelled wrong down here — not the usual station stench of piss and diesel ghosts, but something colder, mineral, like the inside of a fridge that had been unplugged for a decade. "No forced entry," she said. "Grille was cut three days ago, according to Transport Police. Kids, probably. Urban explorers." "Then why's the cut fresh?" Whitfield frowned, leaned in to look at the grille propped against the wall behind them. The edges gleamed, metal shavings still bright, not oxidised the way three-day-old cuts ought to be down here in the damp. "Maybe they came back," he offered. "Maybe." She didn't believe it, and from the way his jaw tightened, neither did he, not really. She stood, knees protesting, and circled the body slowly, the way she'd learned from eighteen years of scenes that made sense and the handful that hadn't. "His shoes," she said. "What about them?" "Dry." Whitfield looked down. The platform floor held a skin of standing water throughout, three days of rain finding its way in through cracks and grilles, pooling in shallow lakes that reflected the torchlight in broken shards. The dead man's shoes, expensive leather, sat untouched by any of it. Not a splash mark. Not a smear. "He didn't walk in," Quinn said. "Carried, then. Killed somewhere else and dumped." "Rigor says otherwise. You don't get that kind of positioning from a dump job. Somebody laid him out. Arranged him." She crouched again, closer this time, studying the crossed arms, the stillness of the face, an expression that held no terror in it at all. Something closer to surprise. "And you don't carry a body through a three-day-old cut grille without getting your own shoes wet." "So what, he floated in?" "I don't know yet." She reached for the evidence bag again, turned the disc so the torch caught the etching properly. Not currency. Not a poker chip. The symbols ran in a circle round a central mark, something that might have been a compass rose if compass roses came from somewhere other than a map. She'd seen markings like it once before, scratched into the doorframe of DS Morris's flat after he vanished off the face of the earth without a body, without an explanation, without anything the coroner's office or the brass could stomach writing down. Three years, and she'd never told anyone what those marks looked like, because nobody had asked, and because putting it in a report would have ended her career faster than any bent case ever could. "Ma'am?" "Bag it separately," she said. "I want it logged under my name, not filed with general evidence." "Chain of custody's going to ask why." "Let them ask." Whitfield hesitated, then did as told, sliding the disc into a fresh bag with the careful reluctance of a man who suspected he was being handed something heavier than its weight suggested. "You think this connects to something," he said. Not quite a question. "I think a man walked in here on dry feet, sat down, folded his arms, and died without a mark on him, in a station that's been sealed for sixty years except for a grille cut so clean it looks freshly minted." Quinn straightened, joints aching in the cold. "I think whoever did this wanted him found. And I think they wanted whoever found him to know exactly how little sense it was supposed to make." "That's not exactly a working theory." "No," she agreed. "But it's a start." She looked once more toward the tunnel mouth, the darkness beyond the torch's reach, and felt the same old itch crawl up the back of her neck that she'd felt three years ago standing in Morris's empty flat. She didn't move toward it. Not yet. She turned instead, evidence bag in hand, and started back toward the grille, already working out who she needed to call, and which of her old contacts might recognise a symbol nobody in this city was supposed to know existed.
