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.

Harlow Quinn ducked beneath the police tape and entered the abandoned station with a bone token sealed in a clear evidence bag. The token had a hole drilled through its centre and a dark stain along one edge. The uniformed constable at the barrier had insisted it was the only way in. Behind her, the last of the Veil Market’s stalls crowded the platform: brass lamps, cabinets of cloudy glass, a butcher’s counter draped in black cloth. Traders watched from behind their wares. No one spoke. Their silence followed Quinn down the tiled steps and into the station’s old ticket office. A man sat slumped beside the dead ticket window. One arm rested on the desk; the other hung over his knee. A knife protruded from his chest. Blood covered the front of his shirt and spread in a dark pool around his shoes. Detective Constable Malik stood by the doorway, careful not to cross the chalk line the crime-scene team had marked. He had a notebook open in one hand. “Elias Venn,” he said. “Market dealer. One stab wound, chest. His cash tin’s empty, and his stall’s been turned over. We’ve got a witness who heard a row, then a shout.” Quinn took in the room. Her closely cropped hair showed silver at the temples under the strip lights. She checked her worn leather watch, then looked at the body. “Who found him?” “Eva Kowalski.” Malik tilted his head towards the platform. “She’s waiting outside. Says she came to buy a book.” Quinn looked through the doorway. Eva stood beside a stack of seized crates, red curls escaping from a woollen hat. Round glasses sat low on her nose. Her leather satchel bulged with books. She tucked a curl behind her left ear, then caught herself doing it. “Did she touch him?” “She says she checked for a pulse.” “Then we’ll hear it from her after the doctor’s done.” Malik’s jaw tightened. “I don’t think this needs an occult consultant, Harlow. It looks like a robbery.” Quinn crouched beside the desk. The blood pool had a clean, curved edge. It stopped short of a scatter of grey dust that lay beneath the chair. She followed the floor’s slope with her eyes. The platform tilted towards the tracks, but the blood had gathered against the raised side of the desk. “What’s your read on the stain?” “Victim fell back, bled out here.” Malik pointed with his pen. “The pool’s contained by the desk leg.” Quinn leaned close without touching the floor. No fine spray marked the desk or the lower wall. The blood clung to the shirt in a flat, dark sheet. At its centre, the knife wound showed a narrow cut through the cloth. The blade’s handle had no blood on it. “Where’s the blood from the wound?” Malik glanced down. “On the shirt.” “Not under it.” She stood and examined the body’s hands. The fingers were half curled, the nails clean. The left hand rested on the desk beside a small brass compass. Its casing carried green patina; protective sigils ringed its face. The needle pointed at the tiled wall opposite the body. “That’s from the stall,” Malik said. “Probably a trinket.” “Probably isn’t a finding.” Quinn moved around the chair. The dead man’s coat had ridden up at the back. Beneath it, a broad purple-red stain darkened the shirt across both shoulder blades. It did not match the pose. A man who had died upright should not have settled blood along his back. She kept her hands behind her. “Did the pathologist give you a time?” “Not yet.” “Get one before you decide how he died.” Malik’s pen stopped over his notebook. “You reckon he was moved?” “I reckon his back tells a different story from his chair.” Quinn let the silence sit. Across the room, the desk drawer hung open. Its lock had no scratches. A thin layer of dust covered the empty compartments, except for a pale rectangle where something flat had rested. The drawer was too narrow for a cash tin. “What was taken?” she asked. “Cash from his stall, as far as we know. The tin’s missing.” “And the stall?” “Shelves knocked over. Stock scattered.” “But no one’s counted it.” “Not yet.” Quinn looked at Malik’s notes. “Then you don’t know what’s missing.” The constable at the door shifted his weight. Malik shut the notebook. Quinn returned to the compass. Its needle held steady on the tiled wall. The nearest tiles showed a film of soot. One, at shoulder height, had a clean crescent along its bottom edge. “Did anyone move this?” she asked. “No.” Malik followed her gaze. “That wall’s solid brick. Service passage was bricked up years ago.” “Who told you?” “The station plans.” “Plans are paper.” From the platform came the scrape of Eva’s satchel against a crate. Quinn stepped into the doorway. “You found the body?” Eva pushed her glasses up. “Yes. I came to see Venn about a manuscript. His stall was open, his chair was tipped over. He was sitting there when I entered.” “Did you see anyone leave?” “No.” “What did you hear?” “A bell. Then something heavy hit the floor.” “How long before you went in?” Eva’s fingers caught her red curl and tucked it behind her ear. “A few minutes.” “A few?” “Three, perhaps. I was at the book stall across the platform. I didn’t want to walk into a fight.” “Did you know him?” “I knew his name. He sold things people didn’t want catalogued.” “Such as?” “Books, mostly. Some had been stolen. Some hadn’t come from any library I could name.” Malik folded his arms. “You called the police over a stolen-book dealer?” “I called because there was a man bleeding on the floor.” Quinn glanced at the satchel. “And what were you buying?” “A book of prayers.” “From a man who sold stolen books.” Eva’s mouth tightened. “I needed to compare a translation.” “Did you find it?” “No. The stall was empty when I got there.” Malik lifted his chin towards the ticket office. “Could be the killer took it.” “Could be,” Eva replied. “But if they robbed him, why leave the gold on his stall?” The question drew Quinn back to the platform. A display case stood on its side, but the objects inside remained: several gold rings, a silver cigarette case, a row of carved bone charms. One charm had a drilled hole like the token in Quinn’s evidence bag. None of the nearby traders had approached the police tape. “What is that compass?” Quinn asked Eva. Eva crossed her arms over her satchel. “A Veil Compass. It points towards the nearest rift.” Malik let out a short breath. “A rift.” “Not north,” Eva continued. “That needle points at the wall for a reason.” Quinn looked from Eva to the compass. “You’re telling me it points through brick?” “I’m telling you what it does.” “Does it point through a door?” “If the door sits near a rift.” Quinn went back into the office. The compass needle still aimed at the clean crescent beneath the tile. She lifted her torch and ran its beam across the wall. The grout around the tile looked darker than the rest. Fine grit had collected in the seam, except at the lower edge. “Get the photographer in here,” she called. “And don’t touch that tile.” Malik joined her at the desk. “Even if the wall’s hollow, it won’t tell us who stabbed him.” “No. But it might tell us how a dead man got into a locked room.” Quinn examined the body again. The shirt beneath the coat carried the same dark staining across the back, the colour settled into the fabric. His collar hid a faint band of bruising at the throat. She leaned closer. Two small crescents showed beneath the jaw, one on each side. “Malik, get the pathologist to check his neck before they move him. And photograph that staining on his back.” “You think he was strangled?” “I think the knife didn’t kill him.” She pointed to the chest. “The wound edges are dry. The blade’s clean. The blood on his shirt sits on the cloth instead of soaking through it. Someone laid him flat, waited long enough for the blood to settle in his back, then carried him here and made a show of the knife.” Malik stared at the body. “That takes time. And a second person, unless the killer was strong.” “Not necessarily. But they needed the room empty.” “The market was open.” “Then they knew how to move through it without being seen.” Eva stood in the doorway, her gaze fixed on the wall. “The market moves every full moon. The station could be gone by tomorrow.” Quinn watched the compass needle tremble once, then settle against the wall again. “Photograph the tile,” she told the scene photographer as he entered. “Every side. Then we’ll find out what’s behind it.”
