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 in Soho didn't fall so much as it dissolved, a grey, greasy mist that turned the neon glow of the Raven’s Nest into a smear of sickly emerald against the pavement. Detective Harlow Quinn stood in the shadow of a recessed doorway, her breath hitching in shallow, rhythmic intervals. She checked the worn leather strap of the watch on her left wrist. Twenty-two minutes past midnight. Across the street, the man she’d been tailing for three blocks paused. Tomás Herrera looked smaller than his file suggested, huddling into the collar of a waxed jacket that had seen better decades. He glanced over his shoulder, his warm brown eyes darting toward the green glow of the bar’s sign. Quinn pressed her back against the brickwork, her sharp jaw tightening. She’d spent eighteen years on the force learning how to disappear into the architecture, and tonight, she was a shadow among shadows. Herrera didn't enter the bar. Instead, he pivoted on his heel and began a brisk, limping stride toward the mouth of the alleyway that bled into the labyrinthine guts of the district. Quinn moved. She didn't run; she flowed with military precision, her boots barely splashing in the oily puddles. She knew Herrera’s pedigree—a disgraced paramedic from Seville who had traded his NHS pension for a life tending to wounds that shouldn't exist. He was the bandage-man for a group Quinn had been circling like a shark for months. If she caught him, she caught the thread that would finally unravel the tapestry of lies surrounding DS Morris’s death. Three years of silence, three years of "unexplained circumstances," and it all led back to the people Herrera treated in the dark. "Police! Stay where you are, Tomás!" The shout broke the muffled silence of the rain. Herrera didn't even look back. He bolted. The chase shifted from a calculated stalk to a desperate sprint. Quinn’s lungs burned with the cold, damp air as she followed him through a shortcut that smelled of rotting refuse and expensive gin. Herrera was fast, driven by a panicked energy that seemed to ignore the slickness of the cobblestones. He took a hard left, then a right, heading toward the northern edge of the district where the city began to crumble into the industrial skeleton of Camden. They reached the outskirts of an abandoned Tube station, its wrought-iron gates hanging off their hinges like broken teeth. Quinn watched as Herrera vaulted a low concrete barrier and disappeared into the maw of the descent. She skidded to a halt at the top of the stairs. The air blowing up from the tunnel wasn't the stale, metallic scent of the London Underground. It was thicker. It carried the smell of ozone, dried herbs, and something metallic—not iron, but copper. Blood. Quinn reached for her hip, her hand finding the familiar comfort of her radio, but she hesitated. If she called for backup, the bureaucrats at the Met would have her badge before she could explain what she was looking for. They’d called her obsessed. They’d called Morris’s death a "tragic accident of geography." She pulled a heavy tactical torch from her belt and flicked it on. The beam cut through the gloom, illuminating the cracked white tiles of the station walls. Herrera was already twenty yards down the escalator, his curly dark hair a bobbing smudge in the dark. "Don't do it, kid," Quinn muttered to the empty air. "You're out of your league." She followed. Each step down into the bowels of the earth felt like a transition. The ambient noise of the city—the distant hum of tires on wet asphalt, the drone of a far-off siren—faded into a heavy, expectant silence. At the bottom of the escalator, she found a makeshift barrier. A man sat on a crate, his face obscured by a hood, his hands tucked into its central pocket. He didn't move as Quinn approached, tactical light shining directly into his chest. "Step aside," Quinn commanded, her voice echoing with the authority of eighteen years of service. The man didn't move. He reached out a hand, palm up. "The toll, Detective." Quinn paused. How did he know her rank? She didn't have her badge out. "I'm in pursuit of a suspect. Move, or I’ll add obstruction to your sheet." "The Market doesn't recognize the Met," the man said, his voice like gravel grinding together. "Only the bone." Quinn remembered a smudge of evidence from a previous crime scene—a small, polished piece of antler carved with strange runes. She reached into her pocket, pulling out a small plastic evidence bag she’d kept as a ‘souvenir’ from the Morris file. Inside was a jagged piece of ivory-colored material. She didn't know why she’d brought it. Intuition, or perhaps a lingering ghost of Morris’s own superstition. She dropped the token into the man’s hand. He closed his fingers over it and leaned back, the barrier creaking open. "Welcome to the Veil, Quinn," the man whispered. "Try not to bleed on the merchandise." She stepped through into the Veil Market. The abandoned station had been transformed. Where there should have been tracks and platforms, there were stalls draped in heavy silks and corrugated iron. The lighting came from jars of luminous moss and flickering tallow candles that smelled of beeswax and old paper. The air was thick with the chatter of a dozen languages, none of which sounded quite human. Quinn kept her hand on the grip of her sidearm, her eyes scanning the crowd. She saw things that defied the clean, logical world of her reports. A merchant with fingers too long for his hands was sorting through a pile of iridescent feathers; a woman in a velvet cloak was haggling over a jar of liquid that seemed to pulse with its own heartbeat. She spotted Herrera near a stall at the far end of the platform. He was speaking urgently to a tall, gaunt figure draped in shadows. Herrera’s sleeve was pushed up, revealing the long scar on his left forearm—the mark of a knife attack that had ended his career and started his descent into this underworld. He was clutching his Saint Christopher medallion with one hand, his fingers white-knuckled. Quinn pushed through the crowd, her shoulder clipping a man who smelled of wet fur. He growled, a sound that started deep in his chest and vibrated in Quinn’s teeth, but she didn't stop. "Herrera!" The paramedic froze. He looked at Quinn, his eyes widening in a mixture of terror and pity. "Detective, you shouldn't be here. This isn't your world." "I make it my world when you people start killing cops," Quinn snapped, closing the distance. She reached out to grab his shoulder, but Herrera ducked, sliding behind the stall of a merchant selling jars of grey, swirling vapor. "I didn't kill anyone!" Herrera shouted over the din of the market. "I save them! Someone has to!" "Then tell me who did!" Quinn lunged, her boots slipping on a patch of something dark and viscous on the floor. She caught herself, but the momentum carried her past Herrera. She turned, ready to pin him against the tiles, but the crowd shifted. The gaunt figure Herrera had been talking to stepped into the light. It wasn't a man. Its face was a mask of pale, stretched skin with no eyes, only indentations where they should have been. It tilted its head, sensing her. "The law has a distinct scent," the creature hissed. "Like old parchment and sour iron." Quinn didn't flinch. She drew her weapon, the cold steel a grounding weight in her hand. "Metropolitan Police. Everyone stay where you are!" The market went silent. The flickering light of the candles seemed to dim. From the shadows of the stalls, more figures emerged—warped, elongated, and hungry. Herrera looked at Quinn, the Saint Christopher medallion swinging wildly against his chest. "Put the gun away, Harlow. They don't care about the Queen's peace down here. You’re just meat in a suit to them." Quinn’s heart hammered a frantic rhythm against her ribs. She was deep underground, surrounded by the impossible, standing in the heart of a bazaar that shouldn't exist. She looked at Herrera, then at the eyeless thing closing the gap between them. The detective didn't lower the gun. She looked the creature in its blank face and felt the ghost of DS Morris standing at her shoulder. "I don't care what you call this place," Quinn said, her voice steady and lethal. "But I’m taking him in. And if any of you want to be the next piece of evidence in my locker, by all means, take a step." Herrera sighed, a jagged sound of defeat. "You're going to get us both killed, Detective." "Maybe," Quinn said, her gaze fixed on the shadows. "But I'm not leaving without the truth."
