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 hammered against Detective Quinn's face as she sprinted down the slick pavement, her boots splashing through puddles that reflected the neon signs above. Her quarry was quick – younger, probably fitter – but Quinn had been chasing suspects through London's streets for nearly two decades. She knew these alleys, knew how to pace herself. The figure ahead darted left into a narrow passage between buildings. Quinn's hand instinctively moved to her weapon as she followed, her breathing measured despite the exertion. The passage opened onto Camden High Street, where late-night revelers scattered as the suspect barreled through them. Quinn caught a glimpse of olive skin, a flash of something metallic around his neck. Tomás Herrera. The unlicensed medic she'd been investigating for months. "Police! Stop!" she shouted, more for the benefit of the startled bystanders than any hope of compliance. Her worn leather watch caught the streetlight as she checked the time – 23:47. Something about that detail nagged at her, but she couldn't spare the mental energy to examine why. Herrera veered suddenly, disappearing down the stairs of a defunct Underground station. Quinn pulled up short at the top of the steps, her training warring with her instincts. The station had been closed for years, supposedly due to structural issues. But over the past three years, since Morris's disappearance, she'd heard whispers about this place. The Veil Market, some called it, though she'd never found anyone willing to elaborate on what that meant. "Damn it," she muttered, drawing her weapon and starting down the stairs. The rain grew distant as she descended, replaced by an odd humming that seemed to emanate from the tiles themselves. Her flashlight beam caught the edges of old advertisements, their colors still somehow vibrant despite years of abandonment. The ticket hall was empty, turnstiles frozen in eternal wait. But there was light coming from somewhere deeper in the station – not the harsh fluorescents of Transport for London, but something softer, more organic. Quinn moved carefully, checking corners, trying to ignore the way the air felt thicker down here, almost syrupy against her skin. A movement caught her eye – Herrera, ducking through a maintenance door. As she approached, she noticed something odd about the lock. Instead of the expected keypad or card reader, there was what appeared to be a small ivory dish mounted beside the handle. Quinn had seen enough evidence photos to recognize bone when she saw it. She reached the door just as it was swinging shut, catching it with her free hand. Beyond lay not a maintenance tunnel, but a wide corridor that should have been physically impossible given the station's layout. The walls were lined with stalls, each illuminated by floating orbs of light that cast everything in an amber glow. The Veil Market. It was real. Vendors called out in languages she both recognized and didn't, selling wares that made her eyes hurt to look at directly. A woman with scales instead of skin offered vials of swirling mist. A man whose shadow moved independently of his body haggled over what appeared to be a living book. Quinn spotted Herrera weaving through the crowd ahead, his Saint Christopher medallion glinting. She pushed forward, trying to keep him in sight while processing the impossible scene around her. This was the missing piece – the thread that could finally explain what had happened to Morris. He'd been investigating a series of mysterious deaths, all connected to unauthorized medical procedures. All connected to Herrera. The market curved in ways that defied euclidean geometry. Quinn's training felt inadequate here – what good was standard procedure in a place that shouldn't exist? But she pressed on, watching as Herrera approached what looked like an ordinary bookshelf wedged between two stalls. It reminded her of the one she'd seen at The Raven's Nest during her surveillance of that bar. Herrera pulled a book, and the shelf swung open like a door. He glanced back, meeting Quinn's eyes for just a moment. There was something like pity in his expression. Quinn raised her weapon. "Stop right there, Herrera!" The crowd parted around them, market-goers pressing against the stalls. Herrera stood in the doorway, one hand still on the book. "Detective Quinn," he said, his Spanish accent more pronounced under stress, "you don't want to follow me through here. Go back up to your world of incident reports and evidence bags. Some mysteries aren't meant to be solved." "Morris followed you through a door like that, didn't he?" Quinn took a step forward. "Three years ago. What happened to him?" Herrera's face softened. "He made a choice. Just like you're about to." He stepped through the doorway. "Sometimes the truth is more dangerous than not knowing." Quinn stood at the threshold, weapon trained on the darkness beyond. The market hummed around her, filled with impossible things and people who weren't quite people. Everything she thought she knew about reality was unraveling, but one thing remained clear: behind that door lay answers she'd spent three years searching for. She thought of Morris, of his empty desk and the questions in his case files that had never been answered. She thought of the way his wife still called the station on the anniversary of his disappearance, hoping for news. Quinn took a deep breath and stepped through the doorway, leaving the last remnants of her familiar world behind.
