You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The call came in as a possible overdose in the old Camden service tunnels, and Harlow Quinn knew immediately that dispatch had it wrong. She stood on the edge of the northbound platform that hadn't seen a train in forty years, her boots planted shoulder-width apart, hands in the pockets of her waxed jacket. The air down here was wrong. It wasn't just the cold that sank into brick after decades without heat. It was the smell. Limestone dust and old creosote and, underneath it all, ozone, like just before lightning struck. The crime scene lights they'd brought down threw hard white cones across a place that wasn't supposed to exist. Six months ago this station had been sealed concrete and a dead-end maintenance shaft. Now there were stalls. Wooden frames lashed together with wire and twine, draped with canvas that rippled though there was no draft. Glass jars lined one table, each stoppered with wax and filled with things that twitched. Another held what looked like teeth strung on copper. A third was nothing but stacked books bound in leather too dark to be cowhide. Price tags were written in chalk in three languages, one of which Quinn didn't recognize. And in the middle of it all, a man lay on his back between two stalls, arms out, eyes open to the vaulted ceiling. "Detective Quinn." Eva Kowalski was already crouched by the body, and that was the second thing that was wrong. The uniform at the top of the service ladder had told Quinn no one else was down here except Scene of Crime waiting on her word. But Eva was here, her curly red hair coming loose from a hasty bun, round glasses fogged then clearing in the cold. Her freckled complexion was pale. Her worn leather satchel, full of books as always, sat open next to her knee. "Who let you down here?" Quinn asked. Eva didn't look up. She tucked a curl behind her left ear, a quick nervous flick. "Marcus at the cordon owed me a favor. And you called me. Remember? You said 'occult researcher, get your arse to Camden now, don't ask questions.'" Quinn had. That didn't mean she'd expected Eva to actually get past the barrier. The entry officer had logged a single bone token presented at 04:17, carved with a crossed circle. Quinn hadn't had one. Eva must have. "Nobody's touched anything?" Quinn said, and immediately checked her own worn leather watch on her left wrist. 04:43. Less than thirty minutes since the transport worker found the door open. "No. Though the market's been empty since I got here. Which is impossible." Quinn stepped closer, careful where she put her feet. Her military precision showed in how she moved around the body without disturbing the dust. The dead man was mid-thirties, good coat, expensive shoes caked with tunnel mud. No visible trauma except his face. His mouth was open too wide and his throat was bruised black in the shape of fingers. "Gallagher," Eva said quietly. "Liam Gallagher. He was a courier. Ran things for the stalls that can't leave during daylight. Bought his token last month." "You knew him." "I knew of him." Eva's green eyes flicked up. Quinn's were brown and unsympathetic in the harsh light. "He wasn't supposed to be here tonight either. The Veil Market moves every full moon. Tonight's waning gibbous. It shouldn't be anchored. Someone held it open." Quinn crouched opposite her, her cropped salt-and-pepper hair catching the light, her sharp jaw set. Eighteen years had taught her to look first at what people wanted her to see. The bruises were obvious. Too obvious. "Strangulation," she said. Eva shook her head. "Look again." Quinn did. The man's coat was unbuttoned. Under it, his shirt was soaked through with sweat despite the cold. His hands were clenched, but not around anything. No defensive wounds. The dust around him was undisturbed except for his own fall pattern. If someone had knelt on him and throttled him, there would be scuffs, displaced grit, knee prints in the filth. There was nothing. It was as if he had lain down and been choked by the air itself. And the bruises. Strangulation left petechiae, burst vessels in the eyes. Gallagher's eyes were clear. The dark marks on his neck weren't thumb-shaped. They were too long, too jointed. The spacing was wrong. "Not hands," Quinn murmured. "No." "The SOCOs upstairs will call it an overdose with a side of erotic asphyxiation and call it a day," Quinn said. "They'll want it to be simple. Old station, druggie with a weird hobby." Eva reached into her satchel and pulled out something wrapped in flannel. She unwrapped it with a reverence that irritated Quinn. It was a small brass compass, its casing mottled with a patina of verdigris. The face was etched with protective sigils, fine lines that hurt to look at directly. "A Veil Compass," Eva said. "Shade made. One of the artisans down here. It doesn't point north." Quinn knew what the Shade were, in the abstract. The way she knew the thing that had taken DS Morris three years ago hadn't been a junkie with a knife, even though the report said it was. She hadn't understood it then. She was starting to. Eva set the compass on the concrete beside Gallagher's shoulder. The needle didn't settle. It spun, lazily at first, then faster, a frantic whir, before snapping hard to a point just behind Gallagher's head and quivering there. Quinn followed its line. Empty air. No, not empty. The air between two stalls seemed thicker, like heat haze over summer tarmac. The canvas there hung perfectly still while the rest rippled. "A rift," Eva whispered. "Someone left it open. The market isn't supposed to be here tonight, Harlow. The last full moon was nine days ago. To anchor it like this you need—" "A lot of juice," Quinn finished. Her partner's case notes had used similar words. A lot of energy, they'd written, as if describing a faulty generator. She stood. Her knees popped. "You're saying that thing killed him." "I'm saying the market takes payment to stay open off-schedule. The bone token gets you in, but to keep the door open you need more. Breath, usually. Sometimes blood." Gallagher's mouth was still open, jaw stretched. Not gasping. Offering. Quinn walked to the haze. The ozone smell grew stronger. The little hairs on her forearms lifted. She'd left her gloves upstairs. Now she was glad. She held her left hand out, palm down, and felt static bite her skin. "Quinn, don't—" "How long would it take?" Quinn asked, not pulling her hand back. Her watch ticked. The second hand seemed to stutter as it passed over the twelve. "To drain the air out of a man's lungs from over there." Eva swallowed. "Seconds. If the rift was hungry." The scene rearranged itself in Quinn's head. Not a murder in the market. A murder *of* the market. Gallagher hadn't been killed here. He'd been brought here. The mud on his expensive shoes — not tunnel mud, she saw now, but Thames foreshore, black and silty and full of grit. He'd been killed somewhere else, somewhere wet, and dragged down after. The sweat on his shirt wasn't sweat. It was condensation. Cold body in warm air, then cold again. Someone wanted it to look like the market killed him. To scare the traders. To close it. She turned back to the body and saw it. Half-hidden under his collar, pressed into the bruised skin, a small chip of white. She crouched again and, with the tip of a pen from her pocket, lifted it. Bone. Not a token. A splinter. Fresh. "Your courier didn't buy his way in," Quinn said. "He was carried. His token was used after he was dead to prop the door." Eva stared at the splinter. Her hand went to tuck hair behind her left ear again. "That means whoever did it knew how to anchor a rift. That's not street knowledge. That's archived. Restricted." Quinn slipped the bone chip into an evidence bag. Her brown eyes were hard, but behind them something clicked into a place that had been empty since Morris died. For three years she'd written supernatural off as grief. Now she had a market that moved with the moon, a compass that pointed at invisible doors, and a body that had been strangled by nothing at all. "Get me a list," she said to Eva. "Everyone who asked for anything about rift anchoring at the Museum in the last month. Every book signed out on the Shade. And find out whose stall that is." She nodded at the haze, where the needle of the brass compass still trembled, pointing at a wound in the world that should not have been there. Eva nodded, already digging in her satchel for her notebook, her books shifting, pages rustling with things that were not quite Latin. Above them, a train rumbled on a live line, distant and indifferent, and the canvas stalls swayed as if in a wind that only the dead could feel.
