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 beneath Camden had been sealed off for nearly a decade, its rusted gates welded shut, its flickering emergency lights long since dead. But Detective Harlow Quinn knew better than to trust the official narrative. She stepped over the yellow police tape with the quiet precision of a soldier on patrol, her boots crunching on broken glass and the occasional brittle bone. The air smelled of damp concrete and something older—something *wrong*. Eva Kowalski stood near the far wall, her round glasses reflecting the sickly glow of the flashlights cast by the handful of uniformed officers clustered around the scene. She tucked a strand of curly red hair behind her ear, her fingers trembling just slightly as she adjusted the strap of her leather satchel. When she saw Harlow, her expression shifted from cautious to wary. "You weren’t supposed to be here," she murmured, her voice low. Harlow didn’t slow her stride. "I wasn’t *supposed* to be anywhere near this case, but here I am." She nodded toward the body—a man in a tailored suit, his face frozen in an expression of frozen terror. His eyes were wide, his mouth slightly ajar, as if he’d been caught mid-scream. The coroner’s team had already begun their work, but the initial assessment was clear: death by asphyxiation. No signs of struggle, no defensive wounds. Just… gone. Eva exhaled sharply. "They’re saying it’s a suicide. Carbon monoxide poisoning from the old ventilation system." Harlow crouched beside the body, her sharp jaw set, her brown eyes scanning the details. The man’s fingers were still curled around a small brass compass, its casing etched with sigils that looked almost like a warning. The needle was pointed straight at the ceiling, as if he’d been holding it there in his final moments. "That’s not what I’m seeing," she said, her voice flat. A uniformed officer stepped forward, his radio crackling. "Detective Quinn, we’ve got the scene secured. You’re the only one who should be down here." Harlow ignored him, her gaze flicking to the walls. The station had been stripped of its original tiles, the concrete exposed in jagged patches. But beneath the dust, she saw something else—scratches, like claws or talons, etched into the surface. Too precise to be accidental. Too deliberate to be random. Eva followed her line of sight. "What is that?" Harlow didn’t answer. Instead, she turned her attention to the body again, running her fingers over the man’s suit jacket. The fabric was too fine, too well-tailored, for a local businessman. And then there was the watch—a sleek, modern piece with a digital display, but the band was tarnished, as if it had been submerged in water for weeks. Or longer. She straightened, her military bearing making the officers around her shift uncomfortably. "This wasn’t a suicide." The coroner, a burly man with a clipboard, cleared his throat. "Detective, the tox screen—" "Wasn’t done yet," Harlow cut in. "And even if it was, we both know carbon monoxide doesn’t leave traces like this." She gestured to the man’s face, the way his lips had turned an unnatural shade of blue, not from lack of oxygen, but from something else. Something *wrong*. Eva stepped closer, her satchel bumping against her hip. "You think it’s supernatural?" Harlow didn’t meet her eyes. "I think this man was looking for something he wasn’t supposed to find." A beat of silence. Then, from the shadows near the far wall, a low chuckle echoed. The officers tensed, their flashlights sweeping the darkness. But there was nothing there—just the usual creaks of an old building settling, the distant drip of water. Eva’s breath hitched. "Did you hear that?" Harlow didn’t answer. She was already moving, her steps measured, her mind racing. The scratches on the wall. The compass. The way the man’s body had been arranged, as if he’d been *placed* there rather than stumbled upon. And then there was the fact that the Veil Market—an underground supernatural black market that only appeared beneath Camden during the full moon—had been rumored to be active again. She reached the far corner of the station, where the concrete had been chipped away to reveal a narrow passage, just wide enough for a person to squeeze through. The air coming from it was thick, humid, carrying the scent of something metallic and old. A rift. Eva hurried to her side. "What is that?" Harlow didn’t look back. "A way in. Or a way out." She reached into her coat pocket and pulled out a small, folded piece of paper—a sketch she’d made earlier that day, of the man’s face, the compass, the scratches on the wall. She unfolded it, holding it up to the dim light. "This man wasn’t just selling information at the Veil Market. He was *collecting* it." Eva’s voice was barely a whisper. "And now he’s dead." Harlow didn’t answer. She was already stepping through the passage, her boots sinking into the damp earth. The officers called after her, but she didn’t stop. She knew what she was walking into. And she knew that if she was right, this wasn’t just another case. This was a hunt.
