System
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.

A detective arrives at a crime scene in an unusual location. Something is wrong — the evidence doesn't add up. A colleague is present, offering a different interpretation. Through careful observation and deduction, the detective begins to see what others have missed. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary.

The abandoned Tube station smelled of copper and old cigarettes, that particular blend of blood and human vice that Harlow Quinn had never quite gotten used to in eighteen years on the force. She ducked beneath the yellow crime scene tape, her worn leather
watch
catching on the plastic as she pushed through. The time on its face read 3:47 AM. She'd been awake for thirty-one hours. "About time you got here." DC
Marcus
Webb stood near the turnstiles, his young face pale in the harsh portable lights the forensics team had erected. He looked green around the gills. First body in an unusual location, Quinn guessed. The rookies always struggled when the setting didn't match the violence. "Traffic was murder." She allowed herself a small, grim smile at her own joke. Webb didn't return it. "Walk me through it." He gestured toward the platform stairs. "Victim's male, mid-thirties, no ID. Found by a pair of urban explorers around midnight. They called it in anonymous, but we've got units tracking them down now." Quinn started down the stairs, her boots clicking against concrete that hadn't seen regular foot traffic since the 1960s. Camden Road station had closed before she was born, relegated to the kind of forgotten urban space that collected the city's castoffs—both animate and otherwise. The walls bore layers of graffiti, some of it artistic, most of it crude. Someone had stenciled a series of strange symbols near the bottom of the stairs, angular markings that looked almost like script but resolved into nothing recognizable. "What about the evidence team?" she asked. "Already
processed
the scene. Photos, samples, the works." Webb hesitated at the bottom of the stairs, hovering near a defunct ticket booth. "I don't mind telling you, guv, this one's strange. The way he's positioned, the things he had on him—" "I'll be the judge of what's strange, Constable." She left him at the booth and crossed the platform to where the body lay beneath a plastic sheet. The station's original tile work rose in arches overhead, cream and brown, decorated with advertisements for products that no longer existed. A ghost of London, preserved in damp and darkness. Dr. Amishi
Patel
, the on-call pathologist, knelt beside the body with her kit open. She looked up as Quinn approached, her expression professionally neutral in a way that told Quinn everything she needed to know about what lay beneath the sheet. "Harlow."
Patel
's greeting
was clipped
. "I was hoping you'd draw this one." "Getting tired of the easy ones?" "Getting tired of the impossible ones."
Patel
stood, rolling her shoulders. "You should see this for yourself." Quinn crouched and lifted the sheet. The victim had been handsome once, in a sharp-featured way that suggested Eastern European ancestry. His eyes were open, staring at the curved ceiling with an expression of mild surprise rather than terror. No visible wounds marred his face or neck. His clothes were expensive—a tailored wool coat over a cashmere sweater, dark trousers, leather shoes that probably cost more than Quinn's monthly rent. "Initial cause of death?" Quinn asked. "That's where it gets complicated."
Patel
moved to the victim's torso and began unbuttoning the coat. "On the surface, nothing. No defensive wounds, no obvious trauma, no signs of strangulation. But look here." She pulled back the coat and sweater to reveal the shirt beneath. The white fabric was stained with something that wasn't quite blood—too dark, too viscous. Quinn leaned closer and caught an odd scent beneath the copper smell. Something mineral, almost sulfuric. "His chest cavity,"
Patel
continued, her voice dropping. "It's been opened. Surgically, from the look of it. The ribs were cut and spread." She hesitated. "His heart is missing, Harlow. Removed with precision I've never seen in eighteen years of practice. No external incision marks on the skin. It's as if someone reached inside him and took it without breaking the surface." Quinn sat back on her heels, processing this. "That's not possible." "No. It isn't."
Patel
's mouth thinned. "But I've run preliminary toxicology. No anesthetics in his system, no paralytics. He was awake when it happened, and he should have been screaming loud enough to wake half of Camden. But there's no damage to his vocal cords, no signs of struggle anywhere on his body. It's like he just... let someone cut him open." Quinn pulled on a pair of gloves from her pocket and began examining the body herself, starting with the hands. The victim's fingernails were clean—no defensive DNA, no blood, no trace evidence. His pockets yielded a wallet with three hundred pounds in cash but no cards, no identification. A set of brass keys. And tucked into his inner jacket pocket, something that made her pause. It was a compass, small enough to fit in her palm. The brass casing had weathered to a greenish verdigris, and the face
was etched
with markings that matched the stenciled symbols on the stairs. The needle spun in slow, deliberate circles, never settling on any direction. "Find something?" Webb had crept down to the platform, his curiosity apparently overcoming his nerves. Quinn pocketed the compass without comment. "What's your read on this, Constable? You've been here since the call came in." Webb shifted his
weight
, glancing at the body and then
quickly
away. "Drug deal gone wrong, I'd say. This station's known for it—urban explorers come down here, kids looking for a thrill, dealers use the tunnels for transactions. Probably got into something over his head. The surgical stuff is strange, I'll grant you, but maybe a message? Organised crime types get creative when they want to send a warning." "A message." Quinn stood, removing her gloves. "You think someone cut his heart out through his intact chest as a message?" "I know it sounds mad—" "It doesn't sound mad, Webb. It sounds convenient." She surveyed the platform, letting her gaze drift across the details. The position of the body—
precisely
centered on the platform, arms at his sides, legs straight. The lack of blood pooling despite the internal damage. The way the portable lights cast shadows that
seemed to
stretch too far, reach too
eagerly
toward the tunnel mouths on either end. Something was wrong here. Not just the physical impossibilities
Patel
had described, but something deeper, something that scratched at the back of Quinn's brain with familiar insistence. She thought of Morris. Three years ago, a routine investigation that had turned into something none of them could explain. Her partner's body found in an alley off Whitechapel, his face frozen in that same expression of mild surprise. No wounds. No cause of death. Just a man who had been alive at 9 PM and dead by 9:30, with no one and nothing to blame. She'd spent three years trying to forget the details. The way the shadows had seemed thicker that night. The cold that lingered in the alley despite the August heat. The feeling, irrational but
overwhelming, that she'd
brushed against something vast and hungry. "Quinn?"
Patel
's voice pulled her back. "Are you all right?" "Fine." She turned to Webb. "You said urban explorers found him. Did anyone check the tunnels?" "Uniforms did a preliminary sweep. Nothing." "Show me where they entered." Webb led her to the eastern tunnel, where a gap in the boarded-up entrance revealed a narrow passage into darkness. Quinn clicked on her torch and stepped through. The tunnel str
etched
ahead, curving
gently
, the rails long since removed. Water dripped somewhere in the distance, a steady rhythm like a pulse. She walked for approximately forty meters before the compass in her pocket grew warm against her hip. She stopped, pulling it out. The needle had stilled, pointing directly ahead into the darkness. Quinn shone her torch forward. The beam caught something on the tunnel wall—a symbol painted in something dark and old, the same angular markings from the stairs. And beside it, a narrow alcove she might have missed entirely if the light had passed over it at a different angle. She approached
carefully
, one hand on the truncheon at her belt. The alcove was barely deep enough to hide a body, but that wasn't what it contained. Instead, she found a small collection of objects arranged with deliberate care: a black candle burned to a stub, a scattering of what looked like bone fragments, and a card propped against the wall. She crouched and read the card's text by torchlight. An address in Camden, near the Lock. And beneath it, words printed in an elegant hand: *The Market moves with the moon. Bring the compass if you want answers.* Quinn pocketed the card and stood. Her heart
was pounding
now, a steady rhythm in her ears that matched the drip of water deeper in the tunnel. For three years, she'd been looking for something to explain what
happened to
Morris. Something to prove she
wasn't losing
her mind. She'd found it. Behind her, Webb's voice
echoed
down the tunnel. "Guv? You find anything?" Quinn looked at the compass in her hand. The needle remained fixed, pointing toward some destination she couldn't see. She thought of the victim's opened chest, his missing heart. She thought of Morris's body in that Whitechapel alley, and the shadows that had moved wrong. "Nothing," she called back, and her voice didn't waver. "Just rats." She tucked the compass away and started back toward the light, already planning her next move. The address. The Market. Whatever waited for her there, she'd find it alone—because some answers weren't meant to be shared, and some evidence didn't add up because it was never meant to follow the rules she'd spent eighteen years learning. The game had changed. And Harlow Quinn in
tended to
win it.
