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.

Rain lashed down on the Soho streets, casting a rhythmic veil over the neon-drenched facades. Detective Harlow Quinn sprinted down Old Compton Street, her eyes locked onto the fleeing figure of Tomás Herrera, his dark curls plastered to his forehead. The suspect's olive skin glistened with rain as he weaved through the sparse nighttime crowd. Harlow's sharp
jaw clenched
in determination; she'd been tracking this lead for weeks, and it wouldn't slip away now. As she gained on Herrera, the sounds of the city grew louder: the wail of sirens in the distance, the chatter of revelers seeking refuge in late-night cafes, and the incessant patter of raindrops on umbrellas. Harlow's worn leather
watch
glinted on her left wrist, a reminder of the time ticking away. She'd been trailing Herrera from The Raven's Nest, where rumors of
clandestine
meetings had drawn her attention. The dimly lit bar's distinctive green neon sign now faded into the distance as the chase led her deeper into the heart of the city. Herrera
suddenly
darted down a narrow alley between two buildings, the entrance almost hidden behind a dumpster. Harlow followed, her military-honed reflexes guiding her through the tight space. The alley opened into a broader, dimly lit passageway – an abandoned Tube station, judging by the faded signs. A handwritten placard on the wall read "Veil Market – Bone Token Required" in crimson letters. Harlow's gut tightened; she'd heard whispers of this hidden market, a hub for the city's supernatural underworld. As Herrera vanished down the stairs, Harlow hesitated, her eyes scanning the deserted platform. The air clung to her like a damp shroud, heavy with the scent of mold and decay. She weighed her options, the thrill of the chase tempting her to follow, but her years of experience screamed caution. This was uncharted territory, potentially teeming with unknown dangers. A figure emerged from the shadows, a hood drawn over their head. "Bone token, love?" they asked, voice low and detached, as they held out a pale, bony hand. Harlow's hand instinctively went to her pocket, but she knew she didn't possess the required token. "Metropolitan Police," she announced, producing her badge. "I'm in pursuit of a suspect." The figure didn't flinch, their gaze lingering on the badge before shifting back to Harlow's face. "Token's the only law down here, Detective. No exceptions." Harlow's sharp jawline tensed as she deliberated. Backtracking would mean losing Herrera, potentially her only lead in the case. But descending into the unknown, without backup or a clear understanding of the market's dynamics, was a perilous gamble. With a deep breath, Harlow made her decision. "I'll take my chances," she said, her voice firm, as she began her descent into the depths of the Veil Market. The hooded figure stepped aside, a hint of curiosity flickering across their obscured face. "Your funeral, Detective." As Harlow Quinn plunged into the darkness, the city above grew more distant, its familiar rhythms replaced by the thrum of the unknown. The sound of her own heartbeat
echoed
through her ears, a
stark
reminder that, down here, she was the outsider. The fluorescent lights of the market's makeshift stalls
began to
materialize below, casting an eerie glow over the deserted platform. Harlow's eyes scanned the crowd, her focus laser-sharp: find Herrera, gather intel, and survive the night. The market's patrons, a diverse array of humans and... others,
began to
take notice of the newcomer. Conversations hushed, and gazes turned toward her. Harlow stood tall, her military precision a comforting familiarity in this strange new world. She knew that, in this alien landscape, her wits and experience would be her only allies. With a deep breath, Detective Harlow Quinn stepped into the heart of the Veil Market, the shadows swallowing her whole.
