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 air beneath Camden stank of rust and cold incense. Harlow Quinn ducked under the yellow tape where it sagged between two ticket barriers. Her boots hit slick tile. The abandoned Tube station breathed around her, a hollow lung of cracked white tiles and dead advertisements. Somewhere water dripped. Somewhere else a generator coughed. This was not a crime scene. This was the Veil Market. Stalls lined the dormant platform where the northbound track used to run. Canvas awnings, iron cages, glass jars full of teeth and smoke and things that moved when she didn't look straight at them. The Market moved every full moon. It required a bone token to enter. Quinn held hers in a fist so tight her knuckles bleached. On the platform edge lay the body. A man in his sixties, thick coat, vendor's apron stained black. No visible wounds. Eyes open. Mouth open. One hand clutched a token of his own, yellowed and polished by years of handling. Eva Kowalski crouched beside him, her worn leather satchel spilled half-open, books fanned across the concrete. "Took you long enough." Eva's green eyes flashed behind her round glasses. Her red curls had come loose from their knot. She tucked a strand behind her left ear, fingers shaking. "You shouldn't be here, Evie." "I got the call before you. Archie owed me three translations." Quinn knelt. The leather of her watch creaked against her left wrist. Her cropped salt-and-pepper hair caught the harsh light from a single work lamp the uniforms had set up. The constable by the stairs shifted his weight. He did not want to be here. None of them did. "What do you see?" Eva asked. "Dead man. No trauma." "Exactly. Heart attack. Look at his face. Look at the position. He fell straight back from his stall." Quinn did not look at his face. She looked at his hands. His right hand held the bone token. His left hand was empty, palm up, fingers curled. White powder caked the creases of his knuckles. She scanned the stall behind him. A low table, black cloth, overturned. Vials rolled into the track bed. One shattered. The powder inside matched the residue on his skin. Labels, handwritten, in a language Quinn did not read. "The constables said natural causes," Eva continued. "Archie was seventy, lived on gin and fried food, his heart -" "Who moved the body?" "No one moved him." Quinn pointed. "He fell straight back, you said. His coat bunched at the shoulders. That happens when someone drags a body, not when a body drops." Eva frowned. Her freckled complexion paled under the work lamp. "Harlow, come on. Who would drag a seventy-year-old apothecary three feet for no reason? There's nothing taken. His coin box is still there." Quinn leaned closer. The man's eyes reflected the light. Pupils blown wide. Not constricted. Not a cardiac event. She lifted his left wrist. Rigor set. His arm held stiff. The white powder left a slick sheen on his skin, not dust, more like dried sweat mixed with something else. "This powder. What is it?" "Banned alchemical salt. Dreamers use it. You inhale it, you see through - you see things. It costs more than gold per grain." "So he knocked his own stock over during a seizure." "Yes. That fits." Quinn stood. Her sharp jaw tightened. She stepped over the body and circled the stall. The Market's air pressed on her sinuses. Behind her, the constable coughed. Vendors watched from the shadows beyond the tape, faces hooded, eyes bright. No one sold when the Met stood on their platform. The stall's black cloth had a clean seam of bare concrete beside it. A perfect rectangle, as if something heavy and flat had sat there until very recent. Dust ringed the edges. "What sat here?" Quinn asked. Eva tucked her hair again. A nervous habit that surfaced when she lied. "How should I know? Stock?" "Archie sold enchanted goods. Information. Banned substances. He sat on the same square of this platform for twelve years, you told me. You told me he never left that square because the rift beneath it kept his wares cold. What sat here that left a cold rectangle?" Eva did not answer. She stared at the body. Quinn dropped to one knee beside Eva's satchel. Books. Old ones. One bound in cracked leather fell open to a page of hand-drawn compass roses. A glint of brass caught the lamp light from beneath Archie's coat. Quinn pulled her sleeve over her hand and pushed the coat aside. A small brass compass lay in his inner pocket, half out, as if he had reached for it and failed. The casing wore a patina of verdigris. The face bore etched protective sigils that caught the light and seemed to shift. The needle spun, lazy and wild, then snapped north-east, toward the dead tracks, and held there with a tremor. Eva sucked in air. "Don't touch that." "Veil Compass. Points to the nearest rift. Crafted by a Shade artisan. You wrote me that essay, remember? Three pages on how you can't buy one for love or money because they break if they touch death." Eva reached out. "It shouldn't point. Not here. The Market sits on a sealed junction, the rifts are capped, that's why we can trade here without things bleeding through. If that needle holds -" "Then a rift opened." Quinn looked at the powder on the dead man's hand again. At the blown pupils. At the token still clutched so tight the knuckle showed white. "Interpretation two," she said. Eva stared at her. "He didn't inhale the salt. He grabbed it. Threw it. Defense." "What?" Quinn pointed at the track bed. The shattered vial lay five feet away from where his hand would have fallen. It had not rolled. The glass sprayed outward from impact. "He threw it at someone standing there. On the tracks. Then someone dragged him back from the edge so it looked like he fell at his stall. Someone who knew how the constables think. Someone who thought heart attack plays better than murder in a market that can't exist." She stood and stepped down onto the track bed. Gravel crunched. The compass needle in her gloved hand jerked harder. Beneath the platform edge, half hidden under a tarpaulin, a second set of footprints marked the dust. Bare feet. Long toes. Wet. Leading from a crack in the tunnel wall that should not exist, a seam of deeper dark that breathed out air too cold for the deep Tube. The powder on the dead man's hand glittered faint in that cold draft. "Archie didn't die because his heart gave out," Quinn said. Eva came to the edge, glasses low on her nose, satchel clutched to her chest. Her voice dropped. "No. He died because he saw what came through." Quinn looked at the open crack. The compass needle now vibrated so fast it hummed.
