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 air in the abandoned Tube station was thick with the scent of damp concrete and something metallic—iron, maybe blood. Detective Harlow Quinn stepped off the final rusted escalator tread, her polished boots clicking
sharply
against the cracked tile floor. The beam of her flashlight cut through the darkness, illuminating the arched ceiling and the graffiti-strewn walls. The station had
been closed
for decades, but it wasn’t empty anymore. Tonight, it was a crime scene. She adjusted the worn leather
watch
on her left wrist, her movements precise, practiced. Her sharp jaw tightened as she took in the scene. Two uniformed officers stood near the platform edge, their faces pale and their voices hushed. Between them lay a body, sprawled awkwardly as if tossed there like a discarded mannequin. Quinn’s brown
eyes narrowed
as she approached. “Detective Quinn,” one of the officers greeted her, his voice tight. “It’s… unusual.” “Unusual?” Quinn
echoed
, her tone clipped. She knelt beside the body, her gaze sweeping over the figure—a man in his thirties, dressed in a dark suit that
seemed to
o elaborate for this place. His skin was pale, almost gray, and his eyes were wide open, staring at the ceiling with an expression of pure terror. She noted the lack of obvious wounds, no blood pooling beneath him. Just the odd metallic smell lingering in the air. “No signs of struggle,” the officer continued. “No visible injuries. But look at his hands.” Quinn shifted her flashlight to illuminate the man’s hands. His fingers
were clawed
, the nails broken and caked with something dark—soil, maybe. She frowned, pulling a pair of gloves from her coat pocket. “Who found him?” she asked, her voice low. “We did,” the officer replied. “Got an anonymous tip. Said there was something down here we needed to see.” He paused, glancing
nervously
at his partner. “But… there’s something else.” Quinn straightened, her bearing military-straight as she turned to face the officers. “Spit it out.” The officer gestured toward the far end of the platform, where a small, leather-bound notebook lay open. Quinn walked over, her boots
echoing
in the cavernous space. She crouched to examine the notebook, her flashlight illuminating the scrawled handwriting. The pages
were filled
with strange symbols—runes, perhaps—interspersed with hastily scribbled notes in English. One phrase caught her eye: *The Veil is thin here.* She flipped through the pages, her frown deepening. The notebook belonged to Eva Kowalski—she recognized the name instantly. Occult researcher. Friend of Aurora Blake. Quinn had crossed paths with her before, always in the periphery of cases that didn’t quite make sense. She tucked the notebook into her coat pocket and turned back to the officers. “Where’s Kowalski?” she demanded. “No idea,” the officer admitted. “She wasn’t here when we arrived. Just the body and the notebook.” Quinn’s mind raced. This wasn’t a typical homicide. The man’s terrified expression, the strange markings on his hands, the notebook’s cryptic notes—none of it added up. She stepped closer to the body again, her flashlight beam tracing the contours of his face. Something glinted faintly in his left hand. She leaned in closer, careful not to disturb the scene. Between his fingers, she spotted a small brass object. She reached for it with gloved hands,
carefully
prying it free. It was a compass, its casing
etched
with
intricate
sigils and tarnished with verdigris. A Veil Compass. Her pulse quickened. She’d heard whispers of these artifacts—tools used to
navigate
the supernatural. But why was it here? And why was it clutched in a dead man’s hand? “Detective?” a familiar voice called from behind her, breaking her concentration. Quinn turned to see Eva Kowalski standing at the edge of the platform, her freckled complexion pale under the harsh light of the flashlight beams. Her curly red hair
was disheveled
, and her round glasses were
slightly
askew. She clutched a worn leather satchel to her chest, her fingers trembling. “Kowalski,” Quinn said, her voice sharp. “Care to explain what you’re doing here?” Eva hesitated, tucking a stray strand of hair behind her ear—a nervous habit Quinn had noticed before. “I was… researching,” she stammered. “There’s a connection between this station and the Veil Market. I thought—” “You thought what?” Quinn interrupted, stepping closer. Her height gave her an advantage, and she used it now, fixing Eva with a steely gaze. “That you’d stumble into a crime scene? That you’d find evidence and leave it lying around for us to clean up?” Eva shook her head vehemently. “No! I didn’t know about the body. I swear. I was following a lead. Someone contacted me, said they had information about the Veil Market. I came here to meet them, but when I arrived…” She trailed off, glancing at the body with a mixture of fear and guilt. Quinn studied her
carefully
, weighing her words. Eva’s explanations were always vague, always
dancing
around the truth without ever fully revealing it. But there was something different this time—a genuine fear in her green eyes that Quinn hadn’t seen before. “Who contacted you?” Quinn asked. “I don’t know,” Eva admitted. “They didn’t give a name. Just said they had something I’d want to see.” Quinn’s jaw tightened. She didn’t believe in coincidences. Eva’s presence here, the Veil Compass, the body—it was all connected. She held up the compass, its needle trembling faintly. “You recognize this?” Eva’s
eyes widened
. “That’s a Veil Compass. They’re rare. Almost impossible to find outside the Market.” “And why would a dead man be holding one?” Quinn pressed. Eva hesitated, her fingers clutching the strap of her satchel. “Unless… unless he was trying to find something. Or escape it.” Quinn’s gaze
flicked
back to the body, her mind racing. The man’s clawed hands, the terror in his eyes—it suggested something unnatural. Something that didn’t fit neatly into her understanding of the world. But she’d seen too much over the years to dismiss it outright. “Detective,” Eva said
softly
, her voice trembling. “There’s something you need to know. The Veil Market… it’s not just a black market. It’s a gateway. People have disappeared there. People who were trying to expose it. I think… I think he was one of them.” Quinn’s pulse quickened. She thought of DS Morris, her partner who had vanished without a trace three years ago. The case had haunted her, the unanswered questions gnawing at her like a persistent itch. And now, standing in this abandoned Tube station, with Eva’s words hanging in the air, she felt a
flicker
of something she hadn’t felt in years—hope. “If you’re lying to me,” Quinn said, her voice low and dangerous, “I’ll make sure you regret it.” Eva swallowed hard but nodded. “I’m not. I swear.” Quinn looked down at the Veil Compass in her hand, its needle quivering as if pointing her toward an unseen destination. She didn’t know what she
was walking
into, but for the first time in years, she felt like she might be close to the truth. And she wasn’t going to let it slip away.
