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.

Detective Harlow Quinn stepped over the police cordon, the stagnant air of the abandoned Tube station pressing against her. Her sharp jaw set in grim determination as she surveyed the scene, the flickering emergency lights casting an eerie glow. This was no ordinary crime scene. The body lay
amidst
a scattering of strange artifacts — a brass compass, the face
etched
with arcane symbols, its needle spinning madly; vials of iridescent liquid; crumbling scrolls covered in an alien script. Harlow crouched beside the victim, a young woman in her mid-twenties. She ran a gloved hand over the girl's pale, freckled face, noting the panicked expression frozen on her features. The body was ice-cold, despite the
oppressive
heat. Harlow frowned, her keen gaze sweeping the scene, piecing together the puzzle. "What have we here, Harlow?" a familiar voice called out. Harlow glanced up to see her colleague, DS Eva Kowalski, picking her way
carefully
through the debris. "Evie." Harlow greeted her with a curt nod. "Looks like our victim stumbled into something she shouldn't have." Eva knelt beside her, adjusting her round glasses as she examined the strange artifacts. "These aren't your average crime scene trinkets," she murmured, her brow
furrowed
in concentration. "This is... occult paraphernalia." Harlow's jaw tightened. "I was afraid of that." She gestured to the compass, its needle still spinning wildly. "Know anything about that?" Eva's green
eyes widened
as she took in the artifact. "A Veil Compass." She reached out a tentative hand, then hesitated. "Used to detect supernatural phenomena. Imbued with powerful magic." Harlow's gaze sharpened. "The Veil Market, then." She rose to her feet, surveying the scene with renewed purpose. "We need to move
quickly
, Evie. This isn't your average homicide." Eva nodded
slowly
, her red curls bouncing as she rose to stand beside Harlow. "You think... the clique is involved?" Harlow's expression darkened. "It's a distinct possibility." She turned, her sharp eyes scanning the debris-strewn platform. "Help me canvas the area. I want to know exactly what happened here." The two women split up, their
footsteps
echoing
in the cavernous space as they searched for clues. Harlow crouched, her fingers tracing the faint impressions in the dust. Bootprints, leading away from the body. She followed their trail, her heart pounding, until they vanished into the shadows. Straightening, Harlow glanced around, her gaze catching on a
glint
of gold
amidst
the debris. She reached down, plucking a small object from the ground. A bone token, carved with a complex design. Her fingers closed around it, and she closed her eyes, focusing. A flash of memory — a dark figure slipping through the shadows, the compass needle spinning wildly. Harlow's eyes snapped open, her jaw set in determination. "Evie." She strode back to where her colleague
was examining
the vials. "I think our victim was lured here. Whoever did this knew what they were looking for." Eva looked up, her green eyes troubled. "The Veil Market." She nodded
slowly
. "It makes sense. But how did they... ?" She gestured
helplessly
at the body. Harlow's expression was grim. "That's what we need to find out." She held up the bone token. "This is our ticket in." Eva's
eyes widened
. "You can't be serious. Harlow, that place is dangerous — " "I don't have a choice, Evie." Harlow's voice was quiet but unyielding. "This is the only way to find out what happened." She glanced down at the body, her heart aching for the young woman whose life had been so senselessly taken. "And to bring her killer to justice." Eva searched Harlow's face, then sighed in resignation. "Alright. But I'm coming with you." Harlow's lips curved in a humorless smile. "I was counting on it." Together, the two women made their way through the winding tunnels, following the twisting paths that led to the hidden entrance of the Veil Market. Harlow ran a thumb over the bone token, steeling herself for what lay ahead. The air grew thicker, the shadows deeper, as they descended. Harlow could feel the
weight
of unseen eyes upon them, the hairs on the back of her neck prickling. Eva clutched her satchel
tightly
, her nervousness evident in the way she kept tucking a stray curl behind her ear. Finally, they reached a heavy iron door, its surface
etched
with arcane symbols. Harlow raised the token, and with a groan, the door swung open, revealing a scene of chaos and wonder. The Veil Market was a labyrinth of stalls and vendors, peddling wares that defied the laws of nature. Harlow's gaze narrowed as she took in the throng of supernatural beings, their features obscured by hoods and shadows. Eva pressed closer to her, her eyes wide with a mixture of fear and fascination. Harlow squared her shoulders, her bearing radiating authority. "Stay close to me, Evie," she murmured. "And keep your eyes open." The two women wove through the crowded market, Harlow's sharp eyes scanning the chaos for any sign of the killer. The compass in her pocket grew warmer, its needle twitching restlessly. Suddenly, a whisper of movement in the shadows. Harlow tensed, her hand dropping to the gun at her hip. A figure emerged, cloaked and hooded, a bone mask obscuring their features. "You're not welcome here, detective," a raspy voice hissed. "This is our domain." Harlow's jaw tightened. "I'm not leaving until I find what I'm looking for." Her fingers tightened around the bone token. "And that's the person who
killed that girl
." The figure chuckled, a dry, mirthless sound. "Then you've already lost." With a sweep of their cloak, they vanished into the shadows. Harlow cursed under her breath, her gaze darting frantically as she searched for any sign of the elusive figure. Eva pressed close to her, her face pale. "Harlow, what do we do?" she whispered, her voice trembling. Harlow's expression was grim. "We keep looking." She glanced down at the compass in her hand, its needle now spinning wildly. "And we follow the trail."
