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 under the tape at the mouth of the abandoned Tube station beneath Camden and the cold hit her first. It was not the cold of an underground platform in November. It cut with a clean edge, a wrong cold that left the skin tight and the breath short. Incense smoke hung in layers beneath the vaulted tile. Stall frames still lined the dead tracks. Crates of bottled shadow, jars with things that pulsed, bundles of dried root that stank of brine and copper. The Veil Market did not close for a death. It held its breath. A uniform at the stairhead lifted the barrier. "You want the bone token back at the end. Market rule." Quinn kept her token in her fist. The shard of bone warmed against her palm. She had earned it three years before and had not used it since DS Morris went down in a room that smelled like this. "Who found him?" The uniform tipped his chin toward the rails. "Stall holder. Five in the morning. Thought he was pissed and sleeping rough until she saw the eyes." Quinn stepped down onto the track bed. Gravel crunched under her boots. Her worn leather watch on her left wrist ticked against the hush. Brown eyes narrowed. Sharp jaw set. Salt-and-pepper crop caught the low light from the strung lanterns. The body lay between the rails on his back. Male, mid-thirties, good coat, cheap shoes. No blood. No wound. Hands open at his sides. Eyes wide, fixed on the soot-black ceiling. Pupils blown to pinpricks of white. Eva Kowalski stood on the opposite rail with her worn leather satchel clutched against her hip. Red curls escaped from beneath a wool hat. Round glasses fogged then cleared. Freckles stood out stark against skin gone pale. She tucked hair behind her left ear and did it again. "You came." Eva's mouth made a thin line. "They called the museum. When a body turns up on a night the Market moves, they call me. I told them not to touch the compass." At the victim's chest a small brass compass rested on his sternum. The casing wore a patina of verdigris at the edges. The face bore fine etchings, protective sigils cut in concentric rings. The needle did not point north. It spun, jerked, spun again, then shivered toward the tunnel mouth and back toward the man's coat pocket. Quinn crouched. She did not touch. "What do you see?" Eva crouched too. "A rift death. The Veil thins here every full moon. The Market moves so it can feed off the thin spot. He pushed too hard or paid for a bad crossing. The energy cooks you from inside. No mark outside. Inside, all the vessels burst." Quinn studied the gravel. "That your professional opinion?" Eva pushed her glasses up. "It fits the last three cases from the archives. Traders call it white-eyed. You go through without a ward and the pressure takes you." Quinn rocked back on her heels. Her gaze traced the shoulders of the coat, the crease of trousers, the soles of shoes. "Show me his hands." Eva frowned. "Hands?" Quinn flicked two fingers at the constable on the platform. "Gloves. Light." The constable handed down a torch and a pair of nitrile gloves. Quinn snapped the gloves on. She lifted the right hand of the dead man. Palm up. The skin was clean. No dirt under the nails. No burn. Left hand the same. She turned each hand over. Knuckles unmarked. "If a rift cooked him, his hands curled. Hot shock makes fists. His hands lie flat. Palms open. As if someone placed them." Eva's brow drew together. "Shock can do odd things." Quinn pointed the torch beam low across the gravel. The stones around the body formed a clear halo, a handspan of undisturbed grit, then beyond that a scuff, a drag line, a smear where grit had been pressed flat. "He did not die here. He died there." The beam fixed on a point two metres down the track, beside a toppled crate of vials. There the gravel showed a deeper impression, a body shape. Gravel had been kicked. A faint print of a shoulder. A dark spot no larger than a coin where something had leaked and dried. "They moved him onto the rails. They set the compass on his chest after." Eva bit her lip. "Why move him at all? Why put him on a track?" Quinn stood. Her knees cracked. She stared at the compass. The needle trembled toward the man's left pocket then snapped back toward the tunnel. "Because the compass points toward the nearest supernatural rift or portal. A Shade artisan makes each one to seek thin places. If he died in the rift, the compass points at the rift. It does not point at his pocket." Eva leaned in. The needle gave another twitch toward the pocket. "You think he had something on him that reads as a rift." Quinn's mouth tightened. "Open the pocket." Eva pulled her satchel strap higher and reached with a gloved hand. She eased the flap of the coat back. Inside, stitched into the lining, a flat packet of oilcloth. She worked it free. The compass needle slammed hard toward the packet and held there, steady as iron to a magnet, the etched sigils on its face catching the lantern light. Eva unfolded the cloth. Inside lay a second bone token, larger than the entry tokens, dark with age and drilled through with a hole packed with wax and hair. The air around it bent. "That is not a Market token. That is a key. A door token. The Market moves every full moon, but a door token holds a rift open. Banned alchemical substance class. The Shade do not sell these to humans." Quinn took the packet without touching the token. She held it under the torch. "Name?" The constable leaned over the platform edge. "No ID. No wallet. Coat label cut out." Quinn turned the man's collar. At the nape, fresh raw skin showed where a label had been razored away that morning. She checked the shoes again. Cheap, but the laces were new, waxed, double knotted with a sailor's hitch. Hands of a man who did not tie his own shoes like that. "He did not dress himself today. Someone else did. Scrubbed the ID, dressed him in a coat that fits the Market, placed him where the rift nips strongest, then left the compass as a marker. So the next trader who comes down that tunnel with a compass finds a dead man and a story about a rift accident and keeps clear." Eva stared at the dark token. Her fingers drummed against her satchel. "You mean murder. But why the theatre? Why not dump him in the Thames?" Quinn lifted the Veil Compass from the chest. The brass was cold. The needle still pulled toward the door token. "Because a dump in the river brings a police dive team. A white-eyed death in the Veil Market brings no one. The Market polices itself. Traders look away. Human law does not apply. The bone token in his fist is entry price. They gave him a token so the Market would let him in, then they took his name, his wallet, cut the labels, and used the Market's own superstition as a lid." She set the compass back down, this time on the gravel at the first scuff mark. The needle spun free and fixed on the distant tunnel mouth where the air shivered, a faint ripple like heat off rails, the true rift. "There is your rift. Back there. Two metres off. The compass knows. The body was moved away from it. If the rift killed him, he drops right on top of it. He does not drop two metres clear on clean gravel with clean hands." Eva exhaled. Her breath fogged. "So someone wanted him found, but found in the wrong story." Quinn eyed the market stalls. Traders watched from the shadows, faces tight, hands tucked out of sight. No one moved to claim the vials by the drag mark. "They wanted a cautionary tale. They left the door token on him as bait or as pay. Either way, the killer knew the Market, knew the compass, knew what Eva would say when she saw white eyes." Eva tucked hair behind her left ear again. Her green eyes met Quinn's over the body. "What now?" Quinn pulled her gloves off finger by finger. Her watch ticked. The sound was loud in the cold. "Now we find who ties double sailor knots and who had access to a Shade door token this moon. We check the roster of who moved stalls tonight. Someone cleared this track before five. The gravel tells us when. The compass tells us where. The hands tell us how." She looked down at the dead man's open palms once more, the clean lines, the utter lack of defence. "And we find out who dressed a dead man with such care."
