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 beneath Camden tasted of wet rust and ancient dust, a flavor that had nothing to do with the city above. Detective Harlow Quinn stood at the edge of the platform, her boots clicking
sharply
against the cracked tiles of the abandoned Tube station. The silence here was heavy, pressing against her eardrums like deep water. Eighteen years on the Met had taught her that crime scenes spoke if you knew how to listen, but this place felt like it
was holding
its breath. She adjusted the worn leather strap of her
watch
on her left wrist, the habit grounding her as her brown eyes scanned the periphery. The floodlights set up by uniformed officers cast long, jagged shadows against the peeling advertisements for concerts that hadn't happened in decades. In the center of the platform lay the body, a dark smudge against the grey concrete. "Detective," a voice called out, too bright for the gloom. "You need to see this." Harlow turned. Eva Kowalski
was crouching
near the yellow tape, her curly red hair a vibrant shock of color in the monochrome station. The younger woman pushed her round glasses up the bridge of her nose, her green eyes wide behind the lenses. Eva clutched a worn leather satchel to her chest as if it contained the crown jewels, though Harlow knew it was likely filled with arcane texts and research notes. "Kowalski," Harlow said, her voice clipped. She moved with military precision, stepping over a coil of caution tape to join her colleague. "I told you to stay behind the line until Forensics cleared the area." "I know, I know," Eva said, tucking a stray curl behind her left ear, a nervous tic Harlow had seen a dozen times in the last month. "But they're missing it, Harlow. Look at the positioning. It doesn't make sense for a mugging gone wrong." Harlow knelt beside the body. The victim was a man in his thirties, dressed in clothes that looked expensive but strangely outdated, as if pulled from a charity bin specializing in the 1920s. There was no blood. No signs of a struggle. His face
was frozen
in an expression not of fear, but of rapturous awe, his pupils dilated so wide the iris was nearly swallowed. "Coroner says cardiac arrest," Eva whispered, leaning in. "Spontaneous. But look at his hands." Harlow examined the man's fingers. They were curled inward, clutching nothing, yet the muscles were locked in a rigid grip. Around his neck hung a small brass compass, the casing covered in a thick patina of verdigris. The face
was etched
with symbols that hurt Harlow's eyes if she stared at them too long—protective sigils, though she didn't know the word for them yet. The needle
wasn't pointing
north. It
was spinning
lazily
, counter-clockwise. "He
was holding
something," Harlow murmured, ignoring the official report forming in her head. "Something he didn't want to let go of, even in death." "That's a Veil Compass," Eva said, her voice dropping to a hush. "It points toward supernatural rifts. Portals. If the needle is spinning like that, it means the energy source is unstable. Or moving." Harlow frowned, her sharp jawline tightening. She hated when Eva slipped into her occult researcher persona. It reminded her too much of the gaps in the Morris file, the three-year-old wound that still
throbbed
whenever the world tilted
slightly
off its axis. "It's a compass, Eva. It's broken. People die of heart attacks every day. Don't go looking for ghosts where there's just bad luck and poor health." "It's not just a compass," Eva insisted, her freckled complexion flushing. "And this isn't just any Tube station. Look at the graffiti." Harlow lifted her gaze from the body to the walls. At first glance, it looked like the usual tagger scrawl—names, dates, crude drawings. But as she focused, the patterns emerged. The tags weren't random. They formed a perimeter. Specific symbols
were repeated
at regular intervals along the tunnel walls, painted in a pigment that
shimmered
faintly under the floodlights. "They're binding runes," Eva explained, sensing Harlow's scrutiny. "Someone was trying to keep something in. Or keep something out. And whoever did it did it recently. The paint is still wet in the crevices." Harlow stood up, brushing dust from her knees. She walked the perimeter, her steps measured. The air grew colder the closer she got to the far end of the platform, where the tracks disappeared into the dark throat of the tunnel. Her breath plumed in front of her, white and sharp. "Temperature drop," she noted aloud, more to herself than to Eva. "No drafts. The ventilation shafts are sealed." "And the smell," Eva added, standing now, though she kept a safe distance from the tunnel mouth. "Do you smell ozone? And... burnt sugar?" Harlow inhaled deeply. Beneath the rust and damp, there was indeed a cloying sweetness, like caramelized sugar left on a hot stove too long, mixed with the metallic tang of a lightning strike. It was the scent of energy discharging violently. She returned to the body, her mind racing. If this was a ritual site, as Eva suggested, the victim wasn't a random casualty. He was a participant. The lack of defensive wounds, the look of awe—it suggested he had walked willingly into whatever happened here. "Check his pockets," Harlow ordered, pulling a pair of latex gloves from her belt. "Gently." Eva nodded, her movements careful as she reached into the man's coat. She withdrew a small, bone-white token, carved with
intricate
spirals. "A bone token," she breathed. "This is an entry key. For the Veil Market." Harlow's stomach tightened. The Veil Market. Rumors had circulated through the precinct for years, dismissed as junkie hallucinations or urban legends. But Morris had believed. Morris had chased whispers of an underground market that moved with the moon, selling things that shouldn't exist. "If he has a token," Harlow said, her voice low and dangerous, "then he was here legally. By their standards. So what killed him? A bad deal?" "No," Eva said, staring at the spinning needle of the compass again. "The Market moves every full moon. Tonight isn't the full moon. It's three days away." Harlow froze. The pieces clicked into place with a sickening finality. The Market wasn't supposed to be here. The binding runes on the wall weren't to protect the station from the outside; they were to anchor the Market to this specific location prematurely. Someone had forced the door open before it was ready. "The energy destabilized," Harlow deduced, looking at the spinning compass. "The rift opened early. The backlash caught him." "But why force it open?" Eva asked, her green eyes fearful. "The risk is enormous. If the veil tears..." "Because someone wanted access to something specific," Harlow finished. She looked down the dark tunnel again. The darkness seemed deeper than it should be, swallowing the light from the floodlamps. "And they took it with them." She checked her
watch
. 02:14. Time
was bleeding
away. "Bag the token and the compass," Harlow commanded, her bearing snapping back into command mode. "I want every inch of this tunnel swept. If the Market moved early, there might be stragglers. Or worse, things that slipped through the crack before it slammed shut." "Harlow," Eva said, hesitating. "If the Market is here, even for a moment... the rules of physics don't apply the same way. Morris..." Harlow cut her off with a sharp glance. "Morris is gone, Eva. We don't know why. But this," she gestured to the body, the strange compass, the humming air, "this is evidence. Tangible. Real. We treat it like a homicide until proven otherwise." She turned toward the tunnel, the darkness beckoning. The scent of burnt sugar was stronger now, intoxicating and wrong. Somewhere in that blackness, a door had
been forced
, and Harlow Quinn in
tended to
find out who held the crowbar. She stepped past the yellow tape, her shadow stretching long and thin against the graffiti-covered walls, walking into the mystery that had claimed so much already.
