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.

Detective Harlow Quinn stood five feet nine inches tall, every inch of her held with the rigid, uncompromising bearing of military precision. She checked the worn leather watch on her left wrist. Three minutes past midnight. The damp subterranean air clung to the closely cropped salt-and-pepper hair at the nape of her neck, smelling sharply of ozone, stagnant ballast water, and the metallic tang of old iron. She swept her gaze across the cavernous expanse of the abandoned Tube station beneath Camden. This was the Veil Market when the moon was full, a place where rumors traded for bone tokens and things best left unnamed changed hands in the dark. Tonight, however, the stalls were gone, replaced by yellow police tape fluttering in the draft from the dark tunnels. A body lay sprawled across the edge of the abandoned platform, half-slumped over the rusted tracks. Forensics had already cleared the immediate perimeter, their magnesium flares casting long, bruised shadows against the curved tile walls of the platform. Quinn stepped past a discarded crate, her sharp jaw set tight. Eighteen years of decorated service with the Metropolitan Police had taught her one fundamental truth: crime scenes told stories. This one was stammering, tripping over its own lies. Detective Sergeant Vance, a heavset man with a permanent sheen of sweat on his forehead and a notebook clutched like a shield, hurried over from the tracks. He was already shaking his head, his breath pluming in the chill air. Rough night for a midnight stroll, Quinn said, her voice a low, even rumble. What do we have, Vance? Open and shut, Vance muttered, gesturing broadly toward the tracks. Fellow named Higgins. Petty crook, mostly fencing stolen electronics and forged passports. Looks like a classic drug deal gone sideways. Stumbled down here, got into a turf war, took a blade to the ribs, and tumbled off the platform. The transit police found him twenty minutes ago. Quinn didn't look at Vance. She was crouched beside the body, her brown eyes tracking the angles of the scene with methodical slowness. Walk me through it, she instructed. Vance flipped open his notebook, reading from his notes as if reciting scripture. Perp approaches from the northern tunnel. Higgins tries to run. Perp catches him right here by the platform edge. Single stab wound to the left intercostal space, right into the heart. Massive internal hemorrhage. Higgins goes over the side. The weapon is missing, likely tossed into the dark. Quinn reached out, her gloved fingers hovering millimeters above the dead man's coat. She didn't touch the fabric, but she leaned in, her gaze sharpening. You mentioned a struggle, Quinn said softly. Vance blinked. Well, yeah. Alley fight. It gets messy. Look at the victim's boots, Vance. Vance frowned, stepping closer and squinting down through the gloom. What about them? The rubber soles, Quinn pointed out, her tone flat. Pristine. Not a speck of soot, ballast dust, or grime. You walk through these tunnels from the street access, your boots look like you've been dragged through a coal chute. Higgins looks like he stepped out of a dry-cleaning van five minutes before his heart stopped. Vance scoffed, stuffing a hand into his pocket. Maybe he took the service elevator. The old maintenance lift works if you know how to wire the box. Quinn stood up, towering over her colleague. She looked past him, down the long, sweeping curve of the abandoned railway line where the darkness swallowed the light entirely. And the blood, Vance? What about it? It's on his shirt. It's on his shirt, yes, Quinn agreed, her eyes narrowing as she processed the impossible geometry of the spill. But look at the splatter pattern on the platform concrete beneath him. Or rather, the lack of it. A man takes a mortal blow to the heart while standing, his blood pressure drops instantly, but the initial arterial spray hits the ground with force. There is zero arterial projection on the platform surface. None. Vance shifted uncomfortably, his pencil tapping against his notebook. Maybe he was stabbed while already lying down. Then why are his knees bruised? Quinn countered, pointing to the distinct, localized contusions pressing through the fabric of the dead man's trousers. He didn't fall here. He was placed here. She began to pace along the platform edge, her boots clicking rhythmically against the stone. Her mind raced back three years, to the case that had shattered her world, the night she lost DS Morris under circumstances that the department's reports glossed over with careful, cowardly lies. There had been no blood there, either. Just a sudden, suffocating cold, and a world that felt fundamentally wrong at the seams. She knelt again, this time inspecting the concrete floor directly beneath the victim's limp hand. Something caught the pale beam of her flashlight—a faint, iridescent smear, glowing with a dull greenish sheen that didn't match anything in the Metropolitan Police forensic kit. It smelled faintly of old parchment and burned copper. Vance leaned in over her shoulder, wrinkling his nose. What's that? Grease? Chemical spill from the old railway cars? Quinn didn't answer immediately. She pulled a small brass evidentiary envelope from her pocket, using a sterile swab to collect a sample of the luminescent residue. The casing of her own watch caught the pale light—a worn leather watch on her left wrist that she had worn every day since Morris died. It felt heavy now, the ticking suddenly loud in her ears. This isn't a grease spill, Vance, Quinn said, her voice dropping an octave. And this wasn't a turf war. Well, if it wasn't a mugging, what is it? Vance asked, his skepticism returning as he snapped his notebook shut. You're overthinking it, Harlow. The city is full of lowlifes killing lowlifes over bad debts. Quinn rose to her full height, her sharp jaw set in a hard line. She looked down at the dead man, then out into the absolute blackness of the tunnel where the Veil Market usually hid its trade. A man doesn't walk into a supernatural black market without a bone token to pay the toll. And he certainly doesn't bleed out without leaving a single drop of evidence on the path behind him. She turned on her heel, her military bearing asserting itself as she looked toward the exit stairs. Get the crime scene techs back here with the ultraviolet lamps, Quinn ordered, her tone leaving no room for argument. And I want the full transit log for the maintenance lift checked for the last twelve hours. Someone carried him down here. Vance hesitated, staring at her as if she had started speaking in tongues. You really think this is tied to the underground market stuff? The urban legends? Quinn walked past him, her hand brushing automatically against the leather strap of her watch. I don't believe in legends, Vance. But I believe in physical evidence. And right now, this body is telling me we're looking at a corpse that was delivered.
