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.

Harlow Quinn's boots struck a precise rhythm against the damp concrete steps, each footfall measured, deliberate. Eighteen years of walking crime scenes had taught her that rhythm meant control, and control was the only thing keeping the darkness at bay. She was forty-one, five-foot-nine of sharp angles and salt-and-pepper hair cropped close to her skull, her brown eyes missing nothing in the gloom. The leather strap of her watch—a battered thing she'd worn since her first day on the force—dug into her left wrist as she descended deeper into the earth beneath Camden. The Veil Market occupied what had once been an abandoned Tube station, a skeletal husk of tile and iron that breathed with a damp, fungal chill. Quinn had passed the bone token to the gatekeeper at the entrance—a jagged thing that had cost her three weeks of favors and a case file she'd rather not remember—and now she stood among the stalls, where vendors sold enchanted goods under flickering gaslight and bioluminescent moss. The air tasted of copper and ozone, thick with the hum of transactions that had no business being legal. She found the scene forty meters in, cordoned off with yellow tape that looked absurdly official against the surreal backdrop. Two uniformed constables stood guard, looking uncomfortable in the supernatural gloom, their hands resting on holsters that would be useless here. Inside the perimeter, a body slumped against a stall draped in midnight-blue velvet, the vendor's wares—vials of mercury-silver liquid, cages containing things that chirped in frequencies that made Quinn's teeth ache—arranged with disturbing neatness around the corpse. Eva Kowalski was kneeling beside the body, her satchel open at her feet like a loyal dog, its leather worn soft by years of books. She was smaller than Quinn by five inches, all curly red hair and freckled skin, her round glasses catching the lantern light as she adjusted them with one hand. Her left hand moved to tuck a strand of hair behind her ear, that nervous habit Quinn had observed in their previous collaborations. "Quinn," Eva said, not looking up. Her voice was careful, measured. "I've checked the vitals. No pulse, obviously, but the body's still warm. Rigor hasn't set in fully. And look at this." She held up a small glass vial, half-empty, the liquid inside swirling with a pearlescent sheen that seemed to move against the light. "Dreamsalt. Bad batch, probably cut with something nasty. He was a dealer in oneiric substances—sold to witches, mostly. The kind who want to walk in dreams." Quinn didn't answer. She circled the body, her boots silent on the grime-slicked tiles. The victim was a man, perhaps fifty, dressed in a velvet waistcoat that had seen better centuries. His face was slack, mouth slightly open, eyes fixed on the ceiling. There was no sign of struggle. No defensive wounds. No needle marks on his neck or arms. Just that slack, surprised expression, as if he'd simply stopped breathing mid-thought. But something was wrong. Quinn crouched, her knees popping with military precision, and leaned close. The man's skin had a grayish undertone, a pallor that didn't match simple asphyxiation or cardiac arrest. It looked, she thought with a cold certainty rising in her gut, like the color of old bruises. She reached out, her fingers hovering near his wrist, then stopped herself. She didn't need to check the pulse. She could see the truth in the set of his jaw, the way his fingers were curled not in pain but in something like ecstasy, or perhaps terror that had locked his muscles after death. "The constables found him like this twenty minutes ago," Eva said, standing now, brushing dust from her knees. She kept her hand near her ear, tucking that wayward curl again. "No witnesses. The stall was locked from the inside, though the key was in his pocket. Classic overdose. The Dreamsalt metabolizes fast—by the time the body's cold, the tox screen will be clean as snow. Whoever did this knew what they were doing." "Or they knew what he was doing," Quinn said quietly. She reached into her coat pocket and withdrew the Veil Compass. It was small, no bigger than a pocket watch, the brass casing mottled with verdigris that spoke of age and use. Protective sigils were etched into the face—geometric patterns that seemed to shift when viewed from the corner of the eye. She'd acquired it three weeks ago, after Morris's case file had been returned to her with the words *supernatural* scrawled across the cover in red ink that hadn't been there before. The needle, when at rest, pointed north. But here, in her palm, it began to spin. Eva's green eyes widened behind her glasses. "You brought the compass. I wasn't sure you would." "It points to rifts," Quinn said, watching the needle. It wasn't spinning randomly. It was hunting, jerking toward a specific corner of the stall, where a section of tile had been recently disturbed, the grout darker than the rest. "And right now, it's pointing at the floor." She moved to the corner, her shadow stretching long in the lamplight. The tile there was loose. Quinn crouched, her fingers finding the edge, and pried it up with a grunt. Beneath it, the concrete was scorched black, radiating outward in a pattern that looked almost like cracks in glass. The air from the gap below smelled of sulfur and something else, something electric and wrong. "There's a rift," Quinn said. "Small one. Probably opened and closed already." Eva joined her, her satchel bumping against her hip. She peered into the darkness, her face pale. "A shade? Or something worse?" "Something that feeds," Quinn said. She looked back at the body, at the gray pallor, the curled fingers, the slack mouth. "This wasn't an overdose, Eva. Look at the eyes." Eva looked. The victim's pupils were dilated, yes, but they weren't round. They were jagged, star-shaped, as if something had burned its way out from the inside. And on the man's wrist—his left wrist—there was a bruise, a dark handprint, five fingers pressed into the skin with enough force to rupture capillaries. "It's not the Dreamsalt," Quinn said, her voice hard as flint. She checked her watch, the leather strap creaking as she noted the time: 11:47 PM. "He was drained. Life force, essence, whatever you want to call it. The overdose was a cover, or maybe he was selling something that attracted the attention of whatever lives in those tunnels." Eva straightened, her expression shifting from professional detachment to something more troubled. "The Market moves on the full moon. This station was here three days ago in a different location. If there's a rift open, it could be anywhere now." "Then we find it before it feeds again," Quinn said. She stood, brushing the dust from her knees, her sharp jaw set with the determination that had made her a detective and would probably get her killed. She looked down at the body one last time, at the handprint bruise that matched the sigil on her compass, and felt the cold weight of recognition. This was Morris's case. Three years ago, DS Morris had been found in an abandoned warehouse, the same gray pallor, the same star-shaped pupils, the same handprint on his wrist. The coroner had ruled it a heart attack induced by experimental drugs. Quinn had known then, in the hollow place where her partner's laughter used to be, that it was a lie. She tucked the compass back into her pocket, feeling its warmth against her thigh, a talisman against the dark. "Eva, get a sample of that Dreamsalt. And check the archives—any other deaths in the last three years with this MO. Gray skin, star pupils, left wrist bruising." "And you?" Eva asked. Quinn was already moving toward the tunnel mouth, where the darkness was deepest and the compass needle was beginning to spin again, faster now, pointing not down, but forward, into the black. "I'm going to find out what killed my partner," she said, and stepped into the dark, her boots striking that precise, measured rhythm, one-two, one-two, marching toward the rift.
