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 Quinn climbed down the rusted ladder into the cavernous gloom of the abandoned Tube station. Damp brick walls arched overhead, slick with condensation. A single bulb swung from fraying cables, halfheartedly slicing through the darkness. Quinn’s boots crunched on shards of broken tiles. Her leather watch face caught the light: precise hands ticking away minutes she couldn’t afford to lose. Eva Kowalski stood near the edge of the platform, fingers brushing the rim of her round glasses. Curly red hair tumbled over her satchel strap, and she tucked a stray lock behind her left ear. Green eyes tracked Quinn’s approach, gleaming with a mix of curiosity and unease. Blood darkened the third rail. A lifeless form lay splayed across the rails, the knees bent at an impossible angle. Quinn crouched, peered at the wound on the victim’s chest—a clean cut, almost surgical. No exit wound. No bone fragments. No blood spatter on the nearby bricks. Eva pressed a hand to the wall. “I counted five sets of footprints leading to the body,” she said. “Then only two leading away.” Quinn frowned. “Give me numbers.” She tapped her watch, as though timing the footprints’ crossing. Eva knelt, her satchel thudding against the damp floor. “Three were fresh. Slightly deeper tread. Then two smaller, faint prints. About the size of a child’s.” She traced the outlines with a finger. “Then nothing.” Quinn rolled her shoulders, eyes drifting over the walls. Blackened streaks led past faded advertisements for late-night shows. She stared at the third rail—dead. The victim wore a long, flowing coat, edges singed. Embroidered along the hem: unfamiliar runes. Nothing in protocol. Nothing in her experience. “What’s he doing down here at two in the morning?” Quinn asked. Voice low and direct. She brushed a strand of salt-and-pepper hair behind her ear. Eva shrugged, lips pressed together. “He was an investigative journalist. Always chasing stories about ghost sightings and missing people. His last assignment mentioned the Veil Market.” Quinn rose, pacing the platform’s edge. Her shadow stretched across the tile like a stalking creature. “The Veil Market.” She repeated the words slowly. “An underground market for enchanted goods. I thought it only existed in rumors.” Eva tapped the runes with a fingertip. “Rumors come from somewhere.” She shot Quinn a look. “He claimed to have a bone token. Entry requirement. Maybe he slipped in and something went wrong.” Quinn’s boots rattled on the grate. “Where’s the token now?” Eva pulled open her satchel. “He carried it too, in a leather pouch.” She rummaged and produced a small bone disc, etched with symbols. “Found it by his hand.” Quinn lifted it, weight surprisingly light. Dried mud clung to its edges. She turned it in her palm, jaw set. “If he used this to get in, then left through the same exit, the footprints should match. They don’t.” Eva glanced at the hanging bulb overhead. It flickered again. “Maybe he never left.” Quinn crouched beside the body again, eyes narrowing. The wound had no bruise or discoloration around it. No powder residue, no blade marks on the ground. She pried open one leather glove. Fingers curled around something. A brass compass, patina flecking its surface. Quinn extracted it. The needle spun crazily, then steadied, pointing toward the tunnel where the tracks disappeared into darkness. Sigils etched around the face shimmered under the bulb’s weak beam. Eva peered over her shoulder. “A Veil Compass. Points toward supernatural rifts.” Quinn rolled the compass between her thumb and forefinger. “So he wasn’t a believing skeptic. He knew what he was tracking.” Eva pressed her lips together. “He must have found more than he bargained for.” Quinn rose, compass clutched against her palm. Her boots thudded as she followed the needle’s direction. The tunnel door had been forced open. Metal groaned. Beyond lay a narrow corridor, choked with dust and half-broken pipes. Quinn paused at the threshold. “Stay here.” Eva swallowed. “If you find anything—” Quinn cut in. “I’ll radio in.” She moved forward, each step echoing. The compass led her to a bricked-up alcove. Fresh mortar disguised a sealed doorway. Quinn ran her fingers over the lines. The surface felt too smooth. Too new. She knelt, pressed her palm flat. The compass needle quivered, flicked toward the bricks. Quinn tapped a finger on a loose brick. It shifted under pressure. She pressed again. With a dull thud, the wall swung inward on hidden hinges, revealing a scattering of bones and candles carved into broken tiles on the floor. Smoke rose from a single candle stub. A circle of runes enclosed a shallow pit etched into the concrete. The pit pulsed with a faint blue glow. Quinn stilled. “Eva.” Footsteps scrambled behind her. Eva appeared at the alcove entrance. Glasses fogged. “The glow—” Quinn pointed. “Portal, or whatever it is, still open.” Eva shifted her satchel. “He used the compass to locate this. Thought he could prove the Market’s existence. Then stepped through.” Quinn frowned. “Body on the tracks, though. He couldn’t have crawled back here after.” Eva knelt beside Quinn, eyes scanning the runes. “Possibly he tried to return through the portal and failed.” Quinn traced a rune with her fingertip. Heat prickled her skin. “This says ‘threshold.’ This one…” She tapped another. “Means ‘crossing.’” Eva leaned closer. “Third one means ‘return.’ It’s incomplete.” Quinn stood, voice low. “He closed it. Or something forced it shut.” Eva brushed sweat from her brow. “That could explain why the portal trapped him on the tracks.” Quinn stepped back, hand finding the compass in her pocket. She gripped it, needle fixed unwaveringly on the alcove. “Look at this.” She swept the compass over the runic circle. The needle spun, then thudded into place against the glass. Eva peered down. “It’s pulsing stronger. Like a heartbeat.” Quinn crossed her arms. “Or a warning. He died not by a blade or by electrocution, but by something—somewhere else.” Eva exhaled. “Supernatural energy.” Quinn’s jaw tightened. “Not natural to my precinct. We’ll need specialists. The Met doesn’t cover this.” Eva tapped her satchel strap. “I have contacts in the museum’s occult section. We could ask them.” Quinn turned to the corridor. The bulb flickered again. Her boots rattled on broken grit. “First, we establish time of death. Lack of blood on the platform suggests he never reached the tracks alive.” Eva nodded, voice soft. “He collapsed right after the portal collapsed behind him. That closed the loop.” Quinn crouched beside the circle again. She examined scorch marks on the concrete floor, tiny fissures glowing faintly blue. No sign of drag marks. No scratch in the mortar. The victim must have vanished mid-stride. “Let forensic teams bag this,” Quinn said. “But seal it off. No contamination. I don’t want anyone poking at those runes until we get confirmation on their nature.” Eva stood. “I’ll call Dr. Leighton. He’s the shadow scholar at the museum.” Quinn surveyed the body one last time. Moonlight glinted off the compass’s brass. She slipped it into her pocket and closed the victim’s hand around nothing. “That circle,” Eva said. “It’s a one-way gate without the return rune.” Quinn opened the alcove door halfway. “When he realised he couldn’t come back, he panicked. Tried to scramble out. Fell here. Suffered the cut from whatever energy collapsed.” Eva pressed a hand to her lips. “That explains the incision—no physical weapon.” Quinn nodded. “He bled from the inside, like tissue tearing at the portal’s edge.” Eva swallowed. “Poor bastard.” Quinn closed her eyes for a moment, then opened them, brown irises cold and precise. “We’ll classify this homicide as unknown until we’ve a proper understanding. But I need every officer out of here.” Eva moved to secure the alcove. “I’ll mark the runes and take photos. No one touches them.” Quinn straightened. She brushed dust from her trousers, checked her watch. “Gather the footprints sample. I want prints older and newer. Then ring the station and warn them—if anyone tries to follow, they’ll vanish too.” Eva gave her a tight smile. “Understood.” Quinn paused at the ladder. She glanced back at the portal’s faint glow, runes pulsing like hungry eyes. She felt the tug of something just beyond clarity. But she would figure it out. Signs missed by everyone else strained to speak their truth. And she listened. She climbed the ladder, leaving Eva behind to guard secrets best preserved in the dark. Above, the station noise had receded. Outside, the world carried on. She stuffed the bone token into her coat pocket and exhaled. Her mind spun hypotheses, each leading away from the familiar into paths she swore she’d never tread again. She checked her watch. Time to solve this.
