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 rain fell in sheets, turning the Soho streets into a labyrinth of slick, black mirrors. Detective Harlow Quinn’s lungs burned, a familiar fire she pushed through with the grim efficiency of a drill sergeant. The suspect—a lean figure in a dark wool coat—was fifty yards ahead and pulling away, moving with a liquid grace that defied the treacherous footing. He didn’t slip, didn’t stumble. He flowed around corners, a smear of motion against the neon haze. Quinn’s worn leather
watch
, a constant on her left wrist, was a cold, heavy presence. She didn’t need to look at it to know how long she’d been running. Time had compressed into the slap of her soles on wet asphalt, the hiss of tires, the frantic thumping of her own heart. The suspect had bolted from the alley behind The Raven’s Nest, that distinctive green neon sign a mocking
beacon
in her peripheral vision. She’d been
watch
ing the place for weeks, certain it was a hub for the clique she
was hunting
. Tonight, she’d
been proven
right. They veered down a narrower street, the air thick with the smell of wet wool and exhaust fumes. The city’s
symphony
of sirens was a distant, irrelevant wail. Down here, it was just the two of them. Quinn’s military bearing kept her posture straight, her gaze locked on the target. She focused on the way the man’s coat flared, the specific cadence of his
footsteps
. He was fast, unnaturally so. A cold knot, one that had lived in her gut for three years, tightened. It was the same feeling she’d had in the moments before everything went wrong with DS Morris. The suspect darted left, plunging them into deeper shadow. Quinn followed, her hand instinctively brushing the grip of the pistol holstered under her arm. The street opened into a small, derelict plaza. At its center was the entrance to an abandoned Tube station, its tiled
facade
stained with decades of grime and vandalism. A chained gate hung open, swaying
slightly
in the wind. This was it. A dead end. Unless… The suspect didn’t hesitate. He sprinted down the steps, disappearing into the maw of the station. Quinn was right behind him, her
footsteps
echoing
on the concrete stairs. The air grew colder, carrying the scent of damp earth, rust, and something else… something ancient and metallic. At the bottom, the suspect stood before a bricked-up archway where the ticket barriers should have been. Quinn slowed, her weapon now in her hand, a solid, comforting
weight
. “Police! Hands where I can see them!” The man didn’t turn. He reached into his coat and pulled out something small and pale. He held it up to the bricks. It looked like a shard of bone, carved with
intricate
symbols. A low hum vibrated through the floor, up Quinn’s legs. The bricks before the man
began to
dissolve, not crumbling but melting away like wax, revealing a passage that glowed with a soft, internal luminescence. The air that wafted out was thick with the smells of ozone, cinnamon, and cloying sweetness. The suspect stepped through without a backward glance. The opening
shimmered
and
began to
shrink. Quinn stood frozen, her mind a battlefield. Every instinct honed over eighteen years on the force screamed at her to call it in. To secure the perimeter. To wait for backup. This was unknown territory. Protocol was law. But the ghost of Morris, his face pale and uncomprehending in the flickering light of a warehouse, whispered a different command. *Don’t let it get away. Not this time.* His death had
been ruled
a misadventure, a structural collapse. But Quinn knew better. She’d seen the impossible things in that room, the symbols on the walls that matched the ones now seared into her memory. This was the same world. The world that had stolen her partner. The opening was now a vertical slit of light, no more than a foot wide. There was no time. “Sod protocol,” she muttered, and lunged forward. She shoved her shoulder through the narrowing gap just as it sealed shut with a sound like grinding stone. For a disorienting second, she was in darkness, then her eyes adjusted. She was not in an abandoned Tube station. She stood in a cavernous space, a natural cavern that had been brutally, beautifully expanded. The air was warm and humid. Above her, the ceiling
was lost
in a gloom that
shimmered
with constellations of bioluminescent fungi, casting a soft,
ethereal
blue-green light. The hum she’d felt earlier was here too, a low, guttural thrumming that vibrated in her bones. This was the Veil Market. She’d heard whispers of it, snatches of interrogation from low-level informants who talked in riddles, but she’d never let herself believe. Stalls
were carved
into the rock walls or fashioned from driftwood and scrap metal. At one, a hunched figure with skin like cracked pottery
was haggling
with a tall, willowy woman over a jar of what looked like trapped lightning. At another, a man displayed a collection of knives that
seemed to
drink the light around them. The sounds were a
cacophony
of murmured transactions, the chime of glass bells, and a strange, reedy music that had no discernible source. Beings of every shape and description mingled in the crowd—some almost human, others so far from it they made her stomach clench. A creature with four arms passed her, its gaze sweeping over her with mild interest before moving on. No one screamed. No one pointed a weapon. To them, she was just another customer. Her suspect
was gone
, swallowed by the throng. The immediate chase was over. She had lost him. But she had found something else. This was the source. The black heart of the city’s rot. The place where the laws of England, the laws of physics, were merely suggestions. Her grip on her pistol tightened. It felt flimsy and inadequate here. She was a cop in a world that had no use for cops. A single, uniformed human in a sea of monsters and magic. Fear, cold and sharp, pricked at her. The sensible part of her, the part that was still Detective Sergeant Quinn of the Metropolitan Police, told her to find the exit and never look back. But the other part, the part that had died with Morris and been reborn as something harder and more driven, knew she couldn’t. This was where she would get her answers. This was where she would get her justice. She took a deep, shuddering breath, the taste of ozone and strange spices filling her lungs. She holstered her weapon; it would only draw the wrong kind of attention. Then, with the sharp jaw set in a line of grim determination, Harlow Quinn stepped forward and disappeared into the impossible crowd.
