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 over London was a relentless, freezing sheet that turned the streets into slick black mirrors. Detective Harlow Quinn checked the worn leather watch on her left wrist. Two fourteen in the morning. Her closely cropped salt-and-pepper hair was plastered to her skull, icy droplets running down the rigid line of her sharp jaw. She exhaled a tight, controlled breath, misting the frigid air, and pushed her aching legs harder. Fifty yards ahead, a shadow darted across the mouth of a narrow Camden alley. Tomás Herrera. Quinn hit the corner without breaking stride, her boots finding traction on the wet cobblestones with military precision. She had been tracking the former paramedic since midnight. The stakeout had begun clear across town in Soho, beneath the distinctive green neon sign of The Raven's Nest. Quinn had sat at the bar for hours, nursing a club soda, her brown eyes tracking Herrera's reflection in a mirror framed by old maps and curling black-and-white photographs. She had waited, patient and motionless, until she saw him slip behind a heavy mahogany bookshelf that swung open to reveal a clandestine back room. Whatever he was doing with the clique in that hidden space, Quinn knew it was illicit. When he emerged from the bar, moving with hurried paranoia, she had trailed him all the way to Camden. Then a stray passing car had splashed a puddle, he had glanced over his shoulder, and the tail had turned into a desperate sprint. Up ahead, Herrera scrambled over a chain-link fence blocking a dead-end street. He was twenty-nine, a decade younger than her, but panic made him clumsy. As he threw his weight over the rusted wire, his saturated trench coat caught on a sharp prong. The fabric tore, peeling back to reveal the olive skin of his left forearm and the jagged, pale lightning bolt of a knife scar running from his elbow to his wrist. His chest heaved as he dropped to the other side, and a silver Saint Christopher medallion briefly swung free from his collar, catching the weak amber light of a streetlamp before he tucked it away. Quinn hit the fence seconds later. She did not hesitate. Eighteen years of decorated service in the Metropolitan Police had trained the hesitation out of her. She scaled the links with economical grace, dropping into the splashing puddle on the far side. Herrera was already disappearing down a set of cracked concrete stairs at the end of the alley. Quinn unholstered her radio, her thumb hovering over the transmission button. She could call for backup. A simple perimeter. But the brass would want to know why she was chasing a disgraced, unlicensed paramedic off the books in the middle of a torrential downpour. Herrera had been stripped of his NHS license for treating patients with impossible, unexplainable methods. The official record called him a quack, but Quinn suspected he was the singular thread tying the clique to a string of supernatural anomalies plaguing her precinct. She thought of Detective Sergeant Morris. Three years. It had been three years since her partner bled out in a warehouse that smelled of brimstone and burnt sugar. The official report cited a gang retaliation, but Quinn had seen the unnatural shadows writhing on the walls that night. She had seen the impossible wounds on Morris's chest. No one had believed her. She did not fully understand the supernatural underbelly of her city yet, but she knew Herrera touched it. She lowered the radio. This had to be done her way. Quinn descended the concrete stairs, the din of the pounding rain fading as she stepped into an abandoned Tube station. The air down here was stagnant, thick with the smell of mildew, ozone, and an undercurrent of something metallic, like copper wire and dried blood. She drew her service weapon, her grip tight and steady. She crept along the tiled wall of the tunnel, her footsteps completely silent. Fifty feet ahead, the corridor opened into a massive cavern previously used as a junction for the trains. Through the gloom, weak light flickered from suspended lanterns. Quinn pressed her shoulder strictly against the damp tile, peering around the corner. Herrera stood before a massive, iron-wrought archway that spanned the width of the train tunnel. Two figures flanked the gate, swathed in heavy, tattered dark gray coats. They did not look entirely human. Their silhouettes were slightly too broad, and their postures held the coiled, aggressive tension of wild dogs. Herrera spoke in rapid, hushed Spanish. From his birthplace in Seville to the shadows of London, he had brought something with him, some knowledge that allowed him to bargain with monsters. He reached into his pocket and produced a small, pale object. From her vantage point, Quinn squinted. It was a piece of carved ivory, or perhaps something more macabre. A bone token. One of the guards snatched the object from Herrera's hand, inspecting it under the lantern light. After a long beat, the guard nodded and shoved the heavy iron gate open. Beyond the archway, Quinn caught a glimpse of a sprawling subterranean bazaar spread across the decaying train platforms. Tents made of patchwork silk and rusted corrugated metal crowded the tracks. Phosphorescent fungi glowed violently in glass jars. The air shimmered with heat and whispered curses, and the chaotic murmur of hundreds of voices echoed off the vaulted ceilings. It was the Veil Market. Quinn felt a cold spike of adrenaline lodge in her throat. She had heard whispers about the Market from desperate informants. An underground network trading in enchanted goods, banned alchemical substances, and secrets that could warp a human mind. They said it possessed no permanent home, shifting through the rotting arteries of London, moving locations every full moon. Tomorrow the lunar cycle would reset, and this entire bazaar would vanish like smoke. Herrera slipped through the iron gates, his dark curly hair disappearing into the throngs of cloaked figures and bizarre, shifting silhouettes. If she lost him now, she might never find the clique. She might never find out what really killed DS Morris. The iron gate began to swing shut. The guards turned their attention back to the tunnel, scanning the shadows. Quinn stood frozen at the edge of the light. Every instinct forged in the academy screamed at her to turn back, to lock down the entrance and return with a tactical unit. But conventional weapons and police cordons meant nothing to the denizens of the Veil Market. If she brought uniforms down here, it would be a massacre. She stared down at her hands. They were steady. The fear was there, cold and rational, but the military discipline she had cultivated over her career clamped down on it like a vice. Quinn holstered her weapon. A gun would instantly out her as law enforcement. She needed to be invisible. She took off her badge and slid it into the deepest, most secure pocket of her coat. As the gate thudded shut, Quinn noted the rusted latch mechanism on the outside. A crude pin system. Easy enough to bypass if she waited for a distraction. Ten minutes later, a trio of figures wrapped in heavy scarves approached the gate from the street level. As they presented their bone tokens and the guards stepped forward to inspect them, Quinn moved. She slipped from the shadows with silent speed, tucking herself directly against the cold iron of the far side of the gate as it opened inward. The moment the guards were distracted by a heated dispute over one of the presented tokens, Quinn slid through the gap, her shoulder bruising against the metal as she forced herself through the narrowest possible space. She was in. The sensory assault was immediate. The stench of roasting meat mixed sickeningly with the cloying sweetness of burning incense. Vials of glowing liquid hissed on makeshift stone counters. Merchants with eyes completely devoid of pupils shouted their wares in languages she had never heard. Quinn pulled the collar of her soaked trench coat high up her neck, keeping her head down, her brown eyes tracking the chaotic crowd. She spotted him. A flash of a silver medallion. The dark, wet curls. Herrera was moving toward a large, heavily guarded tent near the edge of the old Jubilee platform. Quinn fell into step behind a group of lumbering patrons, mirroring their slow, shuffling pace. She was in unfamiliar territory, surrounded by the impossible, armed only with her grit and a singular, burning need for the truth. Let the storm rage above. Her ghost was down here, and she was going to catch him.
