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 hammered London's streets like bullets, turning the asphalt into a mirror that reflected the city's neon veins. Detective Harlow Quinn pressed herself against the brick wall of a closed newsstand, her brown eyes tracking movement through the downpour. Thirty meters ahead, Tomás Herrera ducked under the green neon glow of The Raven's Nest, his Saint Christopher medallion catching the light as he glanced over his shoulder. Quinn's worn leather
watch
showed half past midnight. She'd been following the former paramedic for three hours, ever since a tip led her to believe he
was connected
to the string of unexplained medical incidents plaguing the city. Bodies found with wounds that defied explanation. Victims who recovered from injuries that should have killed them. The kind of cases that reminded her too much of Morris. Herrera pushed through the bar's entrance, the door swinging shut behind him. Quinn waited, counting seconds, her military-trained posture rigid despite the cold rain seeping through her coat. She'd learned patience during eighteen years on the force, but tonight felt different. Tonight felt like the night she might finally get answers about what had killed her partner three years ago. The bar's door opened again. Herrera emerged, moving with purpose down the narrow Soho street. He carried a small leather satchel now, one that hadn't been in his possession when he'd entered. Quinn pushed off from the wall, her
footsteps
silent on the wet pavement as she followed. Herrera turned left onto Old Compton Street, then right into a maze of smaller roads that Quinn knew well from her years patrolling this district. But instead of continuing toward the main thoroughfares, he descended into an alley she'd somehow never noticed before. The detective frowned, quickening her pace. She knew every inch of these streets. By the time she reached the alley's mouth, Herrera had vanished. Quinn drew her flashlight, the beam cutting through sheets of rain to illuminate crumbling brick walls and overflowing rubbish bins. Nothing. She moved deeper into the narrow passage, her sharp jaw set with determination. The alley ended at what
appeared to
be a maintenance entrance to the Underground. But the door stood
slightly
ajar, and warm air drifted up from below, carrying scents that made no sense: cinnamon, old parchment, something metallic that might have been blood. Quinn approached the door, every instinct screaming caution. She pressed her ear to the gap and heard voices
echoing
from somewhere far below. Multiple voices, speaking in languages she couldn't identify. One of them belonged to Herrera – she was certain of it. Quinn tested the door. It swung open on well-oiled hinges, revealing a staircase that descended into darkness. This wasn't any Tube station she knew. The walls were older than London Transport, carved from stone that predated the Victorian tunnels. Symbols
were etched
into the rock, worn smooth by time and countless passing hands. She should call for backup. Should report her location. Should follow protocol. But Morris had followed protocol, and Morris was dead. Quinn descended the stairs, her flashlight beam
dancing
across the strange symbols. The air grew warmer with each step, and the voices grew clearer. She caught fragments now: discussions of prices, of rare items, of services that couldn't be found elsewhere in the city. Her fifteen years of detective work had taught her to recognize the rhythm of black market transactions. The staircase ended at a heavy wooden door bound with iron. Light seeped around its edges, and the voices were loud enough now that she could make out individual words. She pressed against the door and peered through a gap between the wood and stone. What she saw defied everything she thought she knew about London. The abandoned station str
etched
out before her, but it bore no resemblance to the derelict tunnels she'd explored during her career. Dozens of stalls lined the platforms, their wares displayed under flickering oil lamps and strange luminescent orbs. People moved between the vendors – people who didn't look entirely human. A woman with skin that
seemed to
shift between scales and flesh. A man whose shadow moved independently of his body. Children with eyes that reflected light like cats'. And there, at a stall near the center of the market, stood Tomás Herrera. He
was speaking
with a vendor whose face
was hidden
beneath a hood, exchanging his leather satchel for a small vial filled with liquid that glowed with its own inner fire. Quinn's hand moved instinctively to her radio, but she hesitated. Who would believe this? How could she explain what she
was seeing
? The official report would read like the ravings of a detective who'd finally cracked under the pressure of too many unsolved cases. But this was real. This market, these people, this world that existed beneath London's streets. And somehow, it
was connected
to the cases that had been haunting her, the unexplained deaths and miraculous recoveries. Connected to whatever had killed Morris. Herrera pocketed the vial and turned toward the exit. Quinn stepped back from the door, her mind racing. She could retreat now, follow him back to the surface, and
try to
build a conventional case. Or she could enter this impossible place and risk everything to find the truth. The worn leather of her
watch
band pressed against her wrist as she
clenched her fist
. She thought of Morris, of the way his body had
been found
with wounds that the coroner couldn't explain. Of the witnesses who spoke of shadows moving wrong, of sounds that human throats couldn't make. The door handle was cold under her palm. Beyond it lay answers, but also dangers she couldn't
begin to
imagine. Detective Harlow Quinn had built her career on facts, evidence, and logic. Now she stood at the threshold of a world where none of those things
seemed to
apply. She turned the handle and stepped through the door.
