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 station had no name on the map the uniforms carried. Above the stairwell, a cracked enamel sign still said CAMDEN SOUTH, though no train had stopped there in forty years. Quinn ducked beneath the crime-scene tape. The steps smelled of wet concrete, old wiring and something sharper, like a match struck and blown out. “Mind the third one,” DS Malik said from below. “It shifts.” She stepped over it. Malik waited at the foot of the stairs with a torch in one hand and his notebook in the other. Beyond him, a tiled passage bent toward the platform. Someone had once painted the walls pale green. Water had peeled the paint into long, curling strips. “Who found him?” “Two maintenance contractors. They were checking the drainage pumps. Service gate was locked when they arrived, and they cut the chain to get out after they found him. Uniforms came the same way.” Quinn glanced at her watch. Twenty past five. The contractors had called it in at four twelve. “Any other way down?” “Not one we’ve found.” The passage opened onto a platform with a single row of fluorescent work lamps running off a police generator. Their cold light reached the track bed and failed there. Across the rails, advertisements from another century peeled off the opposite wall. A wooden bench stood beneath a clock whose hands had stopped at eleven seventeen. A man sat at one end of the bench. His chin rested on his chest, as though he had fallen asleep waiting for a train that would never come. The scene examiner looked up from her kit. Quinn acknowledged her with a nod and stopped short of the numbered markers on the floor. Malik took his place beside her. “Male, mid-thirties, no ID. Syringe by his right foot. Small vial in his coat pocket. Could be an overdose. Could be whoever sold it to him decided this was a good place to leave him.” “A locked station?” “The contractors say the service gate’s chain had fresh scratches. Someone might have opened it and put it back.” Quinn studied the dead man. Dark wool coat, inexpensive but recently cleaned. Black boots. No hat. His right sleeve had been pushed above the elbow. “Where’s the puncture?” The examiner rose. “I haven’t found one on the arm. I’m not finished.” Malik said, “He may have used another site.” “He may have.” Quinn crouched beside the syringe without touching it. Its translucent cap remained snug over the needle. Malik followed her gaze. “They might have capped it afterward.” “Why?” “To hide what they’d given him.” “Then leave the syringe?” He didn’t answer. Quinn was glad of it. Malik was a good detective because he could offer an explanation without marrying it. She shifted to look at the man’s face. There was a faint gray line of dust across his right cheek, and another on the shoulder of his coat. Nothing on his trouser knees. Nothing on the toes of his boots. “Can you lift his chin?” she asked the examiner. The woman put on fresh gloves and did. The man’s mouth fell slightly open. Behind his left ear, almost lost in the hairline, was a dark point no wider than a pencil lead. Quinn leaned closer. “That wasn’t from the fall,” she said. “No.” The examiner aimed a penlight at it. “I’ll need the postmortem before I tell you what made it.” Quinn straightened. The mark might mean nothing. A small wound could come from any number of things. The capped syringe, though, had been placed where everyone would see it. “Lividity?” she asked. “Back and shoulders. He spent some time lying down.” Malik looked from the body to the bench. “So they carried him in after he died. Still sounds like a drop-off.” Quinn walked the length of the bench. Four feet from the body, a paper cup stood on the floor beside the tiled wall. It was empty. Its rim had gone soft, but the floor around it was dry. “This his?” “Could be,” Malik said. “No prints yet.” On the wall above it, a rectangular patch was cleaner than the surrounding tile. Something had hung there recently. Two screw holes showed at its upper corners; below them, dust clung to the grout. “What was there?” “Sign, perhaps. Contractors didn’t know.” Quinn turned back toward the service passage. Dust covered the platform in a thin, even skin wherever the scene team hadn’t walked. The dead man’s boots were clean along the soles. She could see the ridges of the left heel where it projected beyond the bench. “He didn’t walk in,” she said. “We know he was carried.” “Do we know where from?” Malik pointed toward the passage. “Only entrance.” She followed its line across the platform. The contractors’ tracks were easy enough to distinguish: broad work boots, wet at the edges, coming in from the stairs. The first uniform had stepped carefully along the platform lip before turning toward the bench. Between those tracks lay a narrower print, already drying, with three close-set bars across its heel. It pointed away from the bench. Quinn moved to the next print, then the next. Malik came with her, keeping to the route the examiner had marked safe. The prints ended at the tiled wall beyond the old clock. They did not turn around. There was no matching trail back to the service passage. “Could be from before today,” Malik said. “Edges haven’t crumbled. And the heel was wet.” “Water gets down here.” “It does.” Quinn looked up. A dark stain spread across the ceiling, but the floor beneath it was dry. A few tiles farther along, water had gathered in a shallow dip. The narrow prints passed beside it without touching it. “Not from either of those.” She took out her torch. At the foot of the wall, dust had been pushed into a thin ridge. Above it, the grout made an almost straight vertical line through twelve courses of tile. Quinn put her face close enough to smell damp mineral and the faint, burnt-match scent again. A draft touched her cheek. “Here,” she said. Malik set down his notebook and pressed the tiles with the heel of his hand. They did not move. He knocked. The sound was dull, much like the rest of the wall. “Old access panel?” he said. “Maybe.” He shone his torch along the grout. “Why hide it?” Quinn thought of the fresh scratches on the gate, the clean patch where a sign had been taken down, the man displayed on a bench with a capped syringe at his feet. Whoever had arranged the body wanted police to find him. Whoever had gone through this wall had not wanted them to follow. She went back to the bench. The examiner had opened the man’s coat. Among the contents of his pockets was a folded receipt, a few coins and a small brass compass. The brass had gone green at the hinge. Fine marks ringed its face, too deliberate to be scratches. Its needle pointed away from the tracks, toward the tiled wall. “May I?” Quinn asked. The examiner sealed it in a clear evidence bag before handing it over. Quinn held the bag level. The needle trembled against the glass, then settled. Malik glanced at it. “Compass in a tunnel. That’ll be reliable.” “Probably not.” She turned the bag through half a circle. The needle swung back toward the wall. “There could be an old power cable behind the tiles.” “There could.” She carried the compass several paces down the platform. The needle shifted, no longer pointing directly across her palm but back toward the place where the prints ended. At the service passage, it angled sharply along the platform. Quinn returned to the wall. The needle came round with her. Malik watched her test it once more. “Magnet in the panel, then.” “Or something close to it.” Through the bag, Quinn could see green corrosion worked into the grooves of the brass. The marks around the face looked familiar. Three years ago she had found similar lines cut into the underside of a table at the last address Morris had visited. She had photographed them because there had been nothing else to photograph. By morning, he was gone. She lowered the bag. “Check the other side of this wall on the station plans,” she told Malik. “Get someone to confirm when that service gate was last opened. And ask the contractors whether the sign was still hanging here when they came down.” Malik looked toward the body. “You think our man brought that compass to find this panel?” “I think someone wants us looking at the syringe.” A faint click came from behind the tiles. Both of them turned. Malik raised his torch. Its beam found the straight grout line, the ridge of disturbed dust, and nothing more. For a moment neither moved. Then he reached for his radio. Quinn kept her eyes on the wall. The draft had stopped.
