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 Camden Lock warehouse smelled of river damp and something else Detective Harlow Quinn couldn't name — copper, maybe, gone sour. She ducked under the tape, flashing her badge at the constable who barely looked old enough to shave. "Who called it in?" "Anonymous, ma'am. Said there'd been a break-in. Uniform found the body twenty minutes ago." The warehouse floor stretched out before her, empty except for stacked pallets and a single figure sprawled near the loading bay doors. No blood pooled beneath him. That was the first thing wrong. A man didn't die like that — collapsed, limbs arranged almost peacefully — without leaving something behind. DS Whitfield crouched beside the body, notebook already out, pen scratching. He glanced up when her shadow fell across him. "Heart attack, I'd wager. No visible wounds, no forced entry that we've found. Probably came in to case the place for a burglary, ticker gave out." "Then why call it a break-in?" "Panicked witness. People say things." Quinn knelt, keeping her knees off the concrete, studying the man's face. Late fifties, decent coat, hands soft — not a manual labourer, not the type to be scoping warehouses for scrap metal. His eyes were open, fixed on the rafters above, and his mouth had frozen in an expression she'd seen only once before, three years ago, on a night she tried very hard not to think about. DS Morris had worn that same look. Right before he'd vanished from a locked room with no exits. "Whitfield, look at his fingers." "What about them?" "They're burned. Fingertips only. Look — blackened, like he'd touched something red hot, but there's no scorch marks anywhere else on him. Not his sleeves, not his palms." Whitfield squinted, unconvinced. "Static shock, maybe. Faulty wiring in this dump wouldn't surprise me." "Static doesn't char flesh." Quinn pulled a pen from her jacket and lifted the collar of the dead man's shirt, careful not to disturb anything a forensics team would want documented. Underneath, at the base of his throat, a mark had been seared into the skin — a spiral, precise, deliberate. Not the kind of thing that happened by accident. "Ritualistic," Whitfield said, and there was a note of dismissal in it, like he'd already decided the word meant *irrelevant.* "Kids messing about, probably. Cult wannabes. We get these staged scenes every few months, you know that." "Staged how? Nothing's staged. There's no candles, no chalk marks, no paraphernalia." Quinn stood, turning in a slow circle. The warehouse was cavernous, empty but for the pallets and a rusted crane suspended overhead, motionless. "If someone wanted this to look like a ritual, they'd have dressed the set. This wasn't for show. This was efficient." "Or it's exactly what it looks like — a random weirdo scaring off looters with parlour tricks, and this poor sod's heart just happened to give out from fright." Quinn didn't answer. She'd learned, over eighteen years, that some scenes talked to you if you let them, and this one had been trying to say something since she'd walked through the door. She crossed to the loading bay doors, testing the chain and padlock still fastened tight. No sign of forced entry there either. "How did he get in, then? Doors are locked from outside." Whitfield straightened, tucking his notebook under his arm. "Side window's broken. Probably his point of entry, if he really did break in." "Show me." The window in question sat eight feet up a brick wall, jagged glass still clinging to the frame, no ladder or crate positioned beneath it to explain how a man in his fifties, soft-handed and unathletic, could've climbed through. Quinn stared at it a long moment. "That glass," she said, "broke outward." "You can't tell that from here." "I can. Look at the shard pattern — it's fanned away from the building, not into it. Something came out of that window, Whitfield. Not in." He shifted his weight, arms crossing. "You're reaching." "I'm observing. There's a difference." She walked back toward the body, crouching again, this time examining the concrete around him. Faint scuff marks radiated outward from where he lay, as if something had circled him before he fell — or after. She traced one line with her finger, careful not to touch, following it toward the shadow beneath the stationary crane. There, half-hidden by rust and grime, sat a symbol scratched into the concrete. Same spiral as the burn on the dead man's throat, but larger, cruder, like it had been carved in haste. "Whitfield. Photograph this before anyone moves that crane." "It's an old warehouse, Quinn. People carve all sorts of nonsense into concrete floors." "With what? Show me a tool on this scene that could score stone like that." She looked up at him, and something in her voice made him stop scribbling. "I've seen a mark like this before. Three years ago." He didn't ask. He knew the story, or thought he did — everyone in the department had heard some version of what happened to DS Morris, filtered through rumour until it became almost comedy, the detective who lost her partner to nothing at all. She watched Whitfield's jaw tighten, watched him decide, again, that this was a conversation not worth having. "I'll get forensics to log it," he said instead. "For the record." "Do that." Quinn stood, brushing concrete dust from her knees, eyes drifting back to the broken window, the outward-fanned glass, the scorched fingertips, the spiral that meant nothing to Whitfield and everything to her. Somewhere in this city, someone sold instructions for symbols like this one. Someone always did. She thought of Eva, hunched over restricted texts in some dim corner of the British Museum, and wondered — not for the first time — whether it was finally time to ask her old excuse of a source a very direct question.
