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 didn’t fall in London tonight; it dissolved. It was a fine, grey-black soot that slicked the pavement of Camden until the streetlights reflected off the asphalt like oil on a knife blade. Detective Harlow Quinn adjusted the collar of her wax-canvas coat, her fingers brushing the damp, salt-and-pepper hair at the nape of her neck. She didn't mind the cold. The cold was a physical thing she could understand, unlike the case files currently gathering dust on her desk at the Met. Fifty yards ahead, Tomás Herrera was a smudge of movement against the brickwork. Quinn checked her left wrist. The worn leather strap of her watch was soaked through, the glass fogged, but she didn’t need to see the hands to know they were losing the light. She had been trailing Herrera since he left a back-alley clinic in Soho. He moved with a frantic, twitchy energy, his hood pulled low over his short, curly dark curls, but Quinn recognized the gait. She’d memorized his file: 5’10”, olive skin, a former paramedic who had traded his NHS pension for a life in the shadows. Herrera ducked into a narrow cut-through between two crumbling Victorian warehouses. Quinn broke into a sprint, her boots slapping rhythmically against the wet stone. She hit the corner and pressed her back against the cold masonry, drawing her breath in measured, silent counts. Eighteen years of service had taught her the geometry of a chase, but Herrera wasn't playing by the usual rules. She peered around the edge. Herrera was standing by a heavy iron grate set into the ground beside a rusted-out dumpster. He was fumbling with something at his throat. Quinn saw the flash of gold—his Saint Christopher medallion—as he reached under his shirt. But it wasn't the medallion he pulled out. He produced a small, jagged object that looked like a fragment of a human rib. He knelt, pressing the bone into a concealed groove in the ironwork. With a heavy, tectonic groan that seemed to vibrate in Quinn’s teeth, the grate slid back. "Herrera! Police! Stay where you are!" Quinn’s voice was a sharp crack in the muffled night. The man jerked his head around. Even through the rain, Quinn saw the flash of his warm brown eyes, wide with a cocktail of terror and something that looked uncomfortably like pity. He didn't say a word. He vanished into the hole, pulling the grate shut behind him. Quinn reached the spot in seconds. She holstered her weapon—it wouldn't do much good against whatever was down there if the whispers she’d heard at The Raven’s Nest were true—and gripped the edge of the grate. It shouldn't have moved for her. It should have been locked tight, a silent sentinel of the London sewer system. But as she touched the iron, she felt a residual warmth, a thrumming hum that made the fine hairs on her arms stand up. She thought of DS Morris. Three years ago, they had stood in a basement not unlike this one. They had found things that defied the laws of physics, and then she had found Morris. He hadn't been murdered, not in any way the coroner could define. He had simply been *unmade*, his eyes turned to glass, his heart stopped by a cold that didn't belong in a human chest. The department had buried the truth. Quinn had spent three years digging it back up. She hauled on the grate. It gave way with a hiss of escaping pressure. Below her, a ladder of rusted rungs led down into a darkness that smelled of ozone, wet earth, and incense. Quinn didn't hesitate. She climbed down, her boots ringing against the metal. The air grew warmer the deeper she went, thick and heavy with a pressurized weight that made her ears pop. At the bottom, she found herself in a vaulted brick tunnel—part of a discarded Tube station, she realized, one of the 'ghost stations' erased from the modern maps. The silence was absolute, save for the distant, rhythmic thumping of a heart that wasn't hers. She followed the tunnel, her hand hovering near her service pistol. The walls began to change. The soot-stained brick gave way to smooth, bioluminescent moss that pulsed with a faint violet light. Around a sharp bend, the tunnel opened into a cavernous concourse that had been transformed into a fever dream of commerce. She had reached the Veil Market. The scale of it stole the air from her lungs. Stalls were fashioned from salvaged Tube carriages and ornate wooden kiosks, draped in silks that shimmered with impossible colors. The ceiling was a tangled canopy of copper pipes and hanging lanterns that burned with green and blue flames. Figures moved through the hazy light—some looked human enough, wearing heavy coats and hushed expressions, while others walked with a gait that suggested too many joints or silhouettes that blurred at the edges. The smell was an assault: charred sage, raw copper, and the sweet, cloying aroma of bruised lilies. Quinn spotted Herrera. He was weaving through a crowd of people gathered around a merchant selling jars of liquid that glowed like captured lightning. He looked back, saw her, and his face paled. He broke into a run, darting past a stall where a woman with translucent skin was weighing out silver dust. "Herrera!" Quinn shoved her way through the press of bodies. She collided with a man who felt as solid as a stone pillar; when she looked up to apologize, she saw only a polished porcelain mask where a face should be. She didn't stop to stare. She chased Herrera toward the back of the market, where the air grew colder and the shadows of the abandoned tracks stretched long and thin. He tripped near a pile of discarded bone tokens, sprawling onto the concrete. Quinn was on him in an instant, her knee pinned against his back, her hand locking his left wrist behind him. "Give me a reason, Tomás," she hissed, her jaw tight. "Give me one reason why I shouldn't haul you back to the surface in cuffs." Herrera gasped, his cheek pressed against the cold floor. "You shouldn't be here, Detective. This isn't your jurisdiction. It isn't anyone's." "I made it my jurisdiction when you started treating people who don't have heartbeats," Quinn said. She caught sight of the scar running along his left forearm, a jagged reminder of the world he’d chosen to inhabit. "I saw what happened to Morris. I know you were at the Nest the night he died. I know your 'clique' knows exactly what killed him." Herrera stopped struggling. He turned his head as much as the floor allowed, looking at her with those brown eyes, now filled with a weary honesty. "Morris died because he looked behind the curtain without a ticket, Quinn. Just like you're doing now." Quinn felt a tremor in the ground. It wasn't a train. It was something deeper, a low-frequency vibration that made the Saint Christopher medallion around Herrera’s neck dance against his skin. From the darkness of the tunnels beyond the market, a sound emerged—a long, dry rattling, like a thousand dead leaves skittering across a tombstone. The market began to change. The green flames in the lanterns flickered and died. The merchants began to pack their wares with practiced, frantic speed. The bone tokens on the floor rattled. "The full moon," Herrera whispered, his voice cracking. "The Market moves tonight. If you're still here when the shift happens, you won't find your way back to Camden. You won't find your way back to anything." Quinn looked behind her. The entrance she had used—the tunnel that led back to the world of rain and sirens and logic—was Begining to shimmer, the brickwork turning translucent, revealing a void of swirling grey mist beyond. She looked back at Herrera. He was the only link she had. He was the key to the shadows that had swallowed her partner, the only man who could tell her why Morris had frozen to death in the height of summer. If she took him back now, she might get her answers, or she might just get them both killed by whatever was rattling in the dark. If she stayed, if she followed him deeper into this impossible geography, she was leaving the world she knew behind. No backup. No badge. Just the leather watch on her wrist and a cold trail three years dead. The rattling grew louder. The violet moss on the walls flared once, brilliantly, then began to fade into grey. "Let me up," Herrera pleaded. "We have thirty seconds before the gate closes. Go back, Quinn. Go back to your damp office and your cold cases. This world doesn't want you." Quinn looked at the fading tunnel to the surface. She thought of the 18 years of service, the decorated record, the military precision of her life. Then she thought of Morris’s frozen eyes. Her jaw set into a hard, sharp line. She pulled Herrera to his feet, but she didn’t lead him toward the exit. She gripped his arm, her fingers digging into the fabric of his hoodie. "Where does the Market move to, Tomás?" she asked, her voice steady. Herrera stared at her, the realization dawning on him. "Somewhere you can't carry a gun, Detective." "Good," Quinn said, staring into the encroaching dark as the tunnel to London vanished entirely, replaced by a wall of solid, ancient stone. "I was getting tired of the rain anyway."
