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 like rusted iron left too long in the rain. Detective Harlow Quinn stepped over the police tape, her boots silent on the cracked tile. The beam of her torch cut through the gloom, illuminating the graffiti-scarred walls of the Camden underpass. It wasn’t just any underpass—this was a place the city had forgotten, a place where the air hummed with the wrong kind of energy. “You’re late,” said DS
Patel
, his voice
echoing
in the cavernous space. He stood near a makeshift stall, its wooden counter sagging under the
weight
of empty glass vials and a scattering of blackened coins. His torchlight
flickered
over a body sprawled on the ground, limbs twisted at unnatural angles. Quinn adjusted the worn leather strap of her
watch
, the second hand ticking too loud in the silence. “Traffic on the North Circular was a nightmare. What’ve we got?”
Patel
exhaled through his nose. “Male, mid-thirties. No ID. Cause of death looks like a heart attack, but—” He gestured to the body. “Look at his hands.” Quinn crouched, her knees protesting the movement. The victim’s fingers
were curled
into claws, the skin str
etched
tight over the knuckles. Not the relaxed grip of a man who’d simply collapsed. She reached into her pocket for a pair of nitrile gloves, snapping them on with practiced precision. “Rigor’s already setting in. That’s fast.” “Exactly. And his pupils—dilated like he saw something right before he died.” Quinn’s torchlight caught the
glint
of something metallic near the body’s outstr
etched
hand. A small brass compass, its face
etched
with strange symbols. She picked it up, turning it over in her palm. The needle spun wildly, then stilled, pointing toward the far wall. “That’s not standard issue,”
Patel
said. “No,” Quinn murmured. “It’s not.” She’d seen enough oddities in her time on the force to know when something didn’t belong. The compass had a patina of verdigris, like it had
been pulled
from a shipwreck, but the etchings on its face were too precise, too deliberate. Protective sigils, maybe. Or something else. She stood, her gaze sweeping over the stall. The empty vials, the coins—none of it looked like the usual drug paraphernalia. “This isn’t a dealer’s setup. This is a market.”
Patel
frowned. “A market? Down here?” “Not the kind you’re thinking of.” Quinn’s torchlight
flickered
over a symbol carved into the stall’s wooden leg—a circle with three intersecting lines. She’d seen it before, in a case file from three years ago. The Morris case. The one that had left her with more questions than answers. “You’re saying this is some kind of black market?”
Patel
’s skepticism was thick enough to cut with a knife. “Not black. *Hidden.*” Quinn pocketed the compass. “This place isn’t on any city records. No permits, no inspections. And yet, someone’s been using it. Regularly.”
Patel
crossed his arms. “You’re reaching, Quinn. Guy probably had a bad batch of something. Heart gave out. End of story.” Quinn ignored him, stepping closer to the body. The victim’s shirt
was torn
at the collar, revealing a faint mark on his skin—a bruise in the shape of a handprint. Not fresh. Days old, maybe. She’d seen marks like that before, too. On Morris. “You’re not listening,” she said. “This isn’t a drug overdose. It’s not even a murder. Not in the way we understand it.”
Patel
scoffed. “Then what is it?” Quinn’s torchlight caught something else—a scrap of paper tucked beneath the stall. She pulled it free, unfolding it
carefully
. The paper was brittle, yellowed with age, and covered in the same strange symbols as the compass. But one word stood out, written in smudged ink: *Veil.* “It’s an invitation,” she said quietly.
Patel
leaned in, squinting at the paper. “To what?” Quinn’s pulse quickened. She knew what it was. Or at least, she knew what it *could* be. The Veil Market. A place whispered about in the darker corners of the city, where things
were bought
and sold that shouldn’t exist. Where people went in and didn’t come out. She’d been chasing it for years. “Something we’re not supposed to see,” she said.
Patel
shook his head. “You’re talking like this is some kind of supernatural crime scene. That’s not how this works, Quinn. We deal in facts. Evidence. Not ghost stories.” Quinn turned the compass over in her hand again. The needle still pointed toward the wall. “Then explain this.”
Patel
opened his mouth, then closed it. “It’s a compass. It points north.” “Not this one.” Quinn held it up,
watch
ing the needle spin
lazily
before locking onto the same spot. “It points *there.*”
Patel
followed her gaze to the far wall, where the tiles
were cracked
and discolored, as if something had pressed against them from the other side. “That’s just a wall.” “Is it?” Quinn stepped closer, running her fingers over the tiles. The surface was cold, unnaturally so, and the air near it hummed with a low, almost imperceptible vibration. She pressed her palm against the wall. The stone gave way
slightly
, like wet clay.
Patel
’s torchlight
wavered
. “What the hell—?” Quinn pulled her hand back. The imprint of her fingers remained,
slowly
filling in like a wound healing. “It’s a door,” she said. “Or it was.”
Patel
’s skepticism
was crumbling
. “You’re saying this place is some kind of… what? Portal?” “Not a portal. A *rift.*” Quinn’s mind raced. The compass, the symbols, the body—it all fit. The Veil Market moved with the full moon, and tonight was the night. She’d been so close, three years ago, before Morris had— She cut the thought off. Not now. “This isn’t our jurisdiction,”
Patel
said, but his voice lacked conviction. Quinn pocketed the compass and the scrap of paper. “It is now.” She turned back to the body, her torchlight catching the
glint
of something else—a small bone token, half-buried beneath the victim’s sleeve. She pulled it free, holding it up to the light. It
was carved
with the same symbols as the compass, the edges worn smooth from handling. “What’s
that?” Patel
asked. Quinn’s jaw tightened. “A key.”
Patel
exhaled
sharply
. “You’re serious about this, aren’t you?” Quinn didn’t answer. She was already moving, her torchlight cutting through the darkness as she followed the compass’s unerring point. The wall
loomed
ahead, the air growing colder with each step. She could feel it—the pull of something beyond, something that didn’t belong in the world she knew. She stopped just short of the wall, her breath misting in the cold. The compass’s needle
trembled
, then stilled. “Quinn,”
Patel
said, his voice tight. “What are you doing?” She didn’t look back. “My job.” And then she stepped forward. The wall gave way like water.
