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.

Quinn stepped off the last rung of the ladder, her boots meeting the damp concrete floor with a muted thud. The abandoned Tube station stretched before her, a cavern of peeling tiles and rusted girders bathed in the unnatural glow of gas lamps that shouldn’t have been alight. The air smelled displaced—too clean, too cold, as if the very atmosphere had been scrubbed by unseen hands. No graffiti. No broken glass. No discarded wrappers or cigarette butts littering the corners. Just the faintest metallic tang beneath the usual damp of old tunnels. Her fingers brushed the worn leather of her watch as she adjusted her coat. Eighteen years on the force had taught her that monsters didn’t always lurk in dark alleys. Sometimes they hid in plain sight, polished and waiting. And sometimes, they hid in places like this. A figure shifted near a steel pillar, the curly red hair catching the flickering light like a beacon in the gloom. "Took you long enough," Eva said, tucking a loose strand behind her left ear. Her round glasses glinted as she exhaled sharply through her nose. Quinn didn’t respond right away. She let her gaze drag over the platform—too symmetrical, too quiet. The ventilation grates weren’t rusted through. The electrical boxes weren’t vandalized. The smell of fresh paint beneath the damp made her jaw tighten. Something was off. She stepped forward, boots clicking against the tiles, and stopped three paces from where Eva stood. “Explain.” Eva waved a hand toward the center of the platform. “Over there. You’re not going to believe this.” Quinn moved without another word, her steps measured, precise. As she rounded the pillar, she saw the body. It floated. A man, early thirties by the look of the stubble along his jaw and the fresh ink on his forearm, hovered a foot above the platform. Limbs arranged like a discarded marionette—legs straight, arms slack at his sides. His eyes were open, clouded, mouth slightly agape as if caught mid-scream. Blood dripped from two precise punctures on his neck, dark and viscous, hanging in the air before splattering onto the tiles below. But the droplets didn’t move in slow motion. They fell like normal blood, too quick, too heavy. Quinn crouched without touching anything, eyes scanning the wounds. Too clean. Too symmetrical. No tearing. No bruising around the entry points. No defensive wounds on his hands or arms. No scuff marks on the platform beneath the floating body. She stood slowly. "You called me down here because someone found a ghost attack." Eva swallowed. "Reports came in. Maintenance worker thought he saw a figure rise from the tracks. Came back with a cleaner crew. Found him like this." Quinn’s teeth clenched behind her lips. "Maintenance workers don’t wander abandoned stations at night. Not unless they’re paid to." She reached into her coat pocket, pulled out the brass Veil Compass. The casing had a patina of green that gleamed dully in the lamplight. She thumbed the lid open. The needle spun for three full rotations before settling due north. No pulse. No quiver toward a rift. No supernatural resonance. She snapped it shut. Eva’s fingers twitched at her side. "Harlow—" "Don’t." Quinn took a single step toward the body, then another. She crouched again, careful not to disturb the scene. Reached out with gloved fingers and lifted the man’s wrist. Cool to the touch. Not cold enough for rigor mortis. She pinched a dried flake of the substance on his neck. It came away like old paint, not blood. Not even stage blood. Something synthetic. Her fingers traced the neck, beneath the collar of the man’s shirt. There—a faint line, almost invisible against the skin. A wire. Her pulse steadied, sharp as a blade. She stood. Eva’s voice cracked. "What is it?" Quinn didn’t answer. She moved to the edge of the platform, scanning the overhead beams. Rust. Age. Dirt. Then she saw it—a frayed nylon thread disappearing into the shadows above. She followed its path with her eyes: up to a rusted pipe jutting from the ceiling, wrapped with fading twine. She didn’t hesitate. She grabbed the thread and pulled. It came away with a snap. The body plummeted. Hit the platform with a meaty thud, limbs splaying unnaturally. The impact sent up a puff of dust from the stale air. Eva flinched. "What the hell did you just do?" Quinn didn’t look at her. She refocused, pulled out the compass again. Thumbed the lid open. This time, the needle spun wildly before locking onto a single point—directly at Eva. The satchel on her shoulder hummed with something unnatural. Quinn holstered the compass. "Empty your satchel," she said, voice low and even.
