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.

Detective Harlow Quinn adjusted the cuffs of her worn leather jacket as she stepped off the rusted service stairs into the damp belly of the abandoned Tube station. The air hung thick with the scent of mildew and something else—something metallic and faintly sweet, like old blood left too long in the sun. She flicked on her torch, the beam cutting through the gloom and illuminating the curved tunnel walls, their white tiles cracked and peeling like sunburnt skin. Eva stood near the center of the chaos, her round glasses glinting in the dim light as she crouched beside a prone figure. The corpse lay sprawled on the filthy platform, limbs splayed at unnatural angles, one arm flung out as if trying to reach something. A dark stain spread across the concrete beneath the head, bright against the grime. Quinn’s jaw tightened. "What’ve we got?" Eva didn’t look up. "Male. Mid-thirties. No ID. Defensive wounds on his hands—trying to fight something off." Quinn moved closer, her boots crunching over broken glass and debris. A shard of green-tinted glass lay near the body, its edges jagged and glinting. She picked it up cautiously, turning it over in her fingers. "From a bottle?" "Not one I recognize. No labels." Quinn’s gaze flicked around the scene. "Nothing else here. No bag, no coat. Just… this." She held up the glass shard. Eva exhaled sharply through her nose. "Could’ve been snatched mid-stride. No signs of struggle before the attack." "Except the defensive wounds." Quinn stepped closer, crouching to examine the man’s face. His eyes were open, wide and glassy, the pupils dilated. A thin line of dried blood crusted at the corner of his mouth. She leaned in, sniffing faintly—chlorine and something like burnt sugar. She stood abruptly. "No signs you’d expect from a mugging gone wrong. His shoes are polished. Watch is a replica Rolex, real gold plating. Not exactly street-wear." Eva finally looked up, tucking her hair behind her ear. "Meaning what?" Quinn ignored the question, her gaze tracking along the platform’s edge. A few meters away, a torn strip of fabric snagged on the broken edge of a bench. She plucked it free—a scrap of fine black wool, barely larger than a handkerchief. "This isn’t from a coat." Eva stood, brushing dust from her knees. “Could’ve been on a suit.” “Or sewn into an lining,” Quinn countered. “Quality fabric. Lining of a tailored coat, maybe.” Quinn walked further, her torch sweeping the length of the platform. At the far end, near a service door half-open to darkness, something glinted on the ground—a single black button, half-buried in grime. She picked it up between thumb and forefinger. “This is from the same garment.” She held it up. The button was heavy, jet black, with a single thin silver stitch—eight holes, military grade. Eva stepped closer. "That's not civilian fabric." Quinn pocketed the button. "No. It’s more. Military tailoring. Hand-stitched." She turned, her eyes narrowing as she studied the tunnel mouth behind them. The Veil Market moved every full moon. This wasn’t the last time it had settled in Camden, but it wasn’t where it usually kept its front door. Too exposed. Too close to the surface. Quinn’s fingers curled around the brass compass in her coat pocket—the Veil Compass. She’d come prepared. Eva watched her. "You think he followed them here." Quinn didn’t answer. Her gaze locked onto a faint smudge on the platform’s edge—not dirt, not grime. Something darker, thicker. She knelt, pressing her fingers to it. When she pulled them back, the tips stained black. She stood. Raising her torch, she let the light climb the curved wall. High above, near the ceiling’s broken skylight, a patch of black liquid dripped slowly, forming a slow, viscous puddle on the tiles below. Quinn’s voice went low. "Not blood." Eva stepped closer, her breath catching. "What is that?" Quinn wiped her fingers on her trousers. "Not from a body. From something else. Something that bleeds… differently." A distant shout echoed from the stairwell above. Eva stiffened. "That’s not one of ours." Quinn’s hand dropped to the holster at her side. She didn’t look back. "Then someone’s walking into a trap." She glanced at Eva. "You got that satchel?" Eva nodded, instinctively tightening her grip. "Good. If this goes sideways, you run. Don’t look back. Don’t stop. And Eva?" Eva met her eyes. "Don’t trust anyone down here. Not even the quiet ones." Eva swallowed, her fingers fumbling as she adjusted her glasses. "What about you?" Quinn turned, torch beam slicing through the dark ahead. "I’m already here." A shadow shifted at the end of the platform—a slow uncoiling from the darkness, something too tall, too thin to be human. Quinn stepped forward. The torchlight caught the glint of silver stitching in the void. Silence. Then— A whisper, barely human. The button in her pocket burned cold.
