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 abandoned Tube station smelled of damp concrete and something older—something that clung to the back of Harlow Quinn’s throat like the ghost of a bad memory. She adjusted the strap of her shoulder holster, the leather creaking softly in the stillness, and stepped over the yellow police tape strung haphazardly across the rusted turnstiles. The beam of her torch cut through the gloom, illuminating the peeling posters of long-forgotten ad campaigns and the occasional glint of broken glass underfoot. “Detective Quinn.” The voice came from deeper in the tunnel, where the air grew thicker, heavier. Harlow didn’t startle. She never did. Instead, she turned her head just enough to catch the flicker of movement in her peripheral vision—Eva Kowalski, her red curls escaping the loose knot at the nape of her neck, her round glasses catching the light as she stepped forward. The woman’s satchel, bulging with books, bumped against her hip with each step. “Kowalski,” Harlow acknowledged, her voice low. “You’re not supposed to be here.” Eva pushed her glasses up the bridge of her nose, a nervous habit Harlow had come to recognize over the past few months. “Neither are you, technically. Not without a warrant.” Harlow exhaled through her nose, a sound that might have been a laugh if she’d been in the mood. “I don’t need a warrant to follow up on a tip.” “A tip from who?” “Doesn’t matter.” Harlow turned back toward the tunnel, her torch sweeping over the graffiti-covered walls. The symbols scrawled there weren’t the usual tags—no bold, spray-painted signatures. These were older. Deliberate. The lines were precise, almost ritualistic, etched into the brick with something sharp. She crouched, running her fingers along the edge of one symbol. The stone was warm beneath her touch, as if it had absorbed heat from something unseen. Eva crouched beside her, her breath hitching slightly. “You feel that too, don’t you?” Harlow didn’t answer. She didn’t have to. The crime scene—if that’s what this was—lay further down the tunnel, where the tracks disappeared into darkness. A body, or what was left of one, was sprawled across the rusted metal, limbs splayed at unnatural angles. The victim was a man, or had been. Now, his skin was stretched too tight over his bones, his face frozen in a rictus of terror. His eyes— Harlow swallowed. His eyes were gone. Not gouged out. Not burned away. *Gone*, as if they’d never been there at all. The sockets were smooth, seamless, like polished marble. “Supernatural,” Eva murmured, her voice barely above a whisper. “This isn’t just some gang hit or a drug deal gone wrong.” Harlow stood, her boots scuffing against the gravel. “No. It’s not.” She moved closer, her torchlight tracing the outline of the body. No blood. No signs of struggle beyond the unnatural positioning of the limbs. The man’s clothes were intact—no tears, no burns, no singe marks. Just… *wrong*. Like he’d been drained of something essential, something that had nothing to do with the physical. “You’re thinking about Morris,” Eva said quietly. Harlow’s jaw tightened. She didn’t look at the other woman. “I’m thinking about the case.” “Bullshit.” Harlow ignored her, crouching again to examine the man’s hands. His fingers were curled inward, as if he’d been clutching something in his final moments. She reached into her pocket and pulled out a pair of latex gloves, snapping them on before carefully prying his fingers apart. Nothing. But the skin on his palms was marked—faint, but unmistakable. A pattern, like the symbols on the wall, but smaller. Delicate. Almost like— “A compass,” Eva breathed. Harlow’s fingers stilled. She looked up. “What?” Eva was already digging in her satchel, pulling out a small, worn notebook. She flipped through the pages, her brow furrowed. “There’s a market. Underground. Supernatural. It moves every full moon, but it’s always accessible through a rift or a portal. The entrance requires a bone token—usually a finger bone, sometimes a tooth. The market sells enchanted goods, alchemical substances, information.” She tapped the page with her finger. “And tools. Like compasses.” Harlow stood, her gloves still on. “You’re telling me this man was killed because of a *compass*?” “Not just any compass.” Eva’s green eyes were bright behind her glasses, her voice taking on the eager cadence of a scholar on the verge of a breakthrough. “A Veil Compass. It’s attuned to supernatural energy—rifts, portals, that kind of thing. If you’ve got one, you can find the market, no matter where it’s hiding.” Harlow exhaled sharply. “And if you don’t have one?” Eva’s expression darkened. “Then you’re either very lucky or very dead.” Harlow turned back to the body, her mind racing. The symbols on the wall. The missing eyes. The compass marks on the palms. It all pointed to something beyond the ordinary, something she’d spent the last three years trying to ignore. But ignoring it hadn’t brought Morris back. Ignoring it hadn’t made the nightmares stop. She crouched again, this time examining the man’s pockets. Empty. No wallet, no ID, no phone. Just a single, small object tucked into the lining of his jacket—a bone. A finger bone, polished smooth, carved with the same symbols from the wall. Harlow held it up between her gloved fingers, turning it in the torchlight. Eva’s breath hitched. “That’s a bone token.” “So he was here for the market,” Harlow said, more to herself than to Eva. “But something went wrong.” “Or someone didn’t want him finding it.” Harlow stood, slipping the bone into an evidence bag. “We need to find out who this man was. And we need to find that compass.” Eva hesitated. “Quinn, the Veil Market isn’t exactly… *friendly*. If this man was killed over the compass, then whoever did it isn’t going to just hand it over.” Harlow’s sharp jaw tightened. “Then we’ll find another way.” She turned back toward the tunnel, her torchlight sweeping over the symbols on the wall once more. There was a pattern here, a thread she could pull. She just had to follow it. And if that meant stepping into the dark? She’d done it before. She’d do it again.
