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 lift shaft at Camden Road smelled of wet pennies and old pigeon. Quinn rode the service cage down with her hands in her coat pockets, watching the concrete slide past in the beam of a constable's torch. Forty metres below the pavement, the cage shuddered and stopped. "Mind the third step, ma'am. Rotted through." "Thank you, Constable." She stepped out onto the platform. Someone had strung work lamps along the tiles, and their white light made the place look like a stage set for a play nobody wanted to see. Green and cream tiles, half of them cracked. A faded roundel on the far wall. A poster for a music hall act that had died before her grandmother was born. In the middle of the platform, a man lay on his back with his arms flung wide. "Detective." DS Pryce pushed off the wall he had been leaning against and held up a paper cup, as if offering her a toast. "Bad news is, the tea's gone cold. Good news is, I've already solved it." "Then I can go home." "Male, mid-thirties, no ID. Track marks on the left arm, needle in the gutter by his foot." Pryce jerked his chin toward the yellow evidence marker. "He wanders down here to get out of the rain, cooks up something stronger than he can handle, and goes over backwards. Cracks his skull on the tile. Tragic. Also Tuesday." Quinn crouched at the man's shoulder. She kept her knees together, her weight balanced on the balls of her feet, and let her eyes travel before she let her mind follow. Grey wool coat. Good brogues. A wedding-ring tan with no ring. Blood had pooled under his head in a dark, tidy halo. "How long since he went over?" "Pathologist's guess is six hours. Maybe seven." "And the rain?" Pryce blinked. "What about it?" "You said he came down to get out of the rain." She lifted the hem of the man's coat between two gloved fingers. "This is dry, Pryce. Dry all the way through. Collar, cuffs, the lot. It's been coming down in stair rods since noon." "So he'd been down here a while." "Six hours, you said. It stopped raining at four. Nobody walks across Camden in that without wringing out." She turned the cuff over. "Look at his shoes." Pryce looked. "They're shoes." "They're clean." She pointed the tip of her pen at the soles, then swept it across the platform. Grey dust lay across the tiles like felt, thick as a thumbnail, and it carried the marks of the last hour: the fat treads of the uniformed officers, the scuffed trail of the paramedic, the long smear where someone had dragged a lamp cable. "Everything that's walked on this platform has left a print. The dust is so deep you could track a mouse. Now find me his." Pryce walked a slow circle around the body. The cup went still in his hand. "Could've come in from the tunnel end," he said. "Then the dust on the tunnel steps would show it. Constable?" The young officer by the lift straightened. "Ma'am?" "Anyone use the north stair before we arrived?" "No, ma'am. It's chained. We cut the padlock ourselves at ten past six." "Rust on the chain?" "Flaking off in my hand." Quinn nodded and returned to the body. She pulled the man's left sleeve up to the elbow. The track marks sat in a neat row, dark and punched into the skin. She held her wrist beside his arm, and the old leather watch strap slid against her cuff as she leaned in. "How old are these?" "Old enough," Pryce said. "He's a user. It's what they look like." "They're healed over. Weeks, not hours. Scar tissue, no bruising, no fresh puncture." She rolled the sleeve down again. "And your needle by the foot? Clean tip. Not a drop of blood on it. Nothing in the barrel." "He used it all." "Then where's the tourniquet? The spoon? The lighter?" Quinn stood, and her knees popped in the cold. "A man who plans his fix carries a kit. This one carries none of it. Check his pockets again." Pryce sighed and knelt. He worked the coat open and went through it with the bored competence of a man who had done it a thousand times. His hands stopped. "Well, now." He drew out a small disc, yellowish-white, the size of a two-pound coin. He turned it over under the lamp. Someone had carved a spiral on one face, fine as a fingerprint. "Bone," he said. "Real bone. Somebody's idea of a lucky charm." "Bag it." Quinn's voice stayed level. "What else?" "Nothing in the left. Right's got..." Pryce's fingers dug deeper, and he pulled out a brass compass no bigger than a pocket watch. Green crust ate at the hinge and along the rim. He thumbed the lid open and frowned. "Bit of junk. Doesn't even work. Needle's all over the shop." "Give it here." She took it in her gloved palm. The face was etched with tiny sigils, angular and deliberate, crowded in concentric rings around the glass. Under them, the needle shivered, swung through a full circle, and slowed. It steadied. It pointed not at the north stair, nor at the lift, but at the blank tiled wall behind the tracks, where a filthy arch had been bricked in decades ago. Quinn turned her wrist. The needle held. She stepped left, and it followed her, correcting itself with a small, patient tremble. "Magnetised something," Pryce said. "The lamps. The cable. Interference." "Then it would point at the lamps." "It's pointing at a wall." "Yes." She lowered the compass. "It is." Pryce got to his feet and dusted his knees. He wore the look of a man who wanted to be finished. "Ma'am, with respect. A dead junkie, a bit of tat in his pocket, and a compass that's on the blink. You're building a cathedral out of a shed." "Humour me. The blood." "What about it?" "How much is on the tile?" He glanced down. "A fair bit." "A halo. Round, even, centred under the skull." She traced the shape in the air. "Head wounds bleed, and they bleed downhill. This platform slopes toward the track by two degrees. I felt it in my ankles coming off the lift. If he cracked his head here, that blood runs to the edge. It doesn't sit in a circle like paint in a tin lid." Pryce opened his mouth. Shut it. "And the wound itself." Quinn crouched again and, with one gloved finger, tilted the man's head to the light. "Depressed fracture, back left. A fall backwards gives you a wide, flat impact. This is narrow. Rounded. Something struck him, once, with something the size of a fist." "So somebody hit him." "Somebody hit him somewhere else." She laid the head down. "Somewhere with rain, and a floor that didn't run downhill. They carried him in without touching a grain of this dust, and they set him down with his arms out like he was posing for a photograph." The lamps hummed. Somewhere in the dark tunnel mouth, water dripped into water, slow and regular as a clock. "You're telling me nobody walked in," Pryce said. "I'm telling you he didn't." Quinn closed the compass lid and held it up between them, and the brass caught the light. Beyond the glass, the needle kept its silent point at the bricked arch. "And I want to know who taught this to find something a wall is hiding."
