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.

Detective Quinn's boots splashed through puddles as she pursued the figure ahead, her breath coming in controlled bursts. The rain pelted her face, but she kept her quarry in sight - a man in a dark jacket who'd bolted from The Raven's Nest the moment she'd shown her warrant card. He was quick, but Quinn had spent eighteen years chasing suspects through London's labyrinthine streets. The suspect darted down an alley off Camden High Street, weaving between overflowing bins and stacks of sodden cardboard. Quinn followed, her hand brushing the grip of her holstered pistol. Her watch clicked against the weapon's metal - a sound that reminded her of Morris, of that last chase three years ago. She pushed the memory aside. Focus on the now. The man ahead stumbled on wet cobblestones, his shoulder clipping a brick wall. In the dim light, Quinn caught a glimpse of olive skin, curly dark hair. Tomás Herrera. The unlicensed medic she'd been investigating for months. He recovered quickly, ducking through a rusted maintenance door that Quinn knew led to an abandoned Tube station. She slowed her pursuit, stopping at the threshold. Water dripped from her close-cropped hair as she studied the darkness beyond. The station had been decommissioned decades ago, but lately she'd heard whispers about what went on in these forgotten spaces beneath the city. Whispers that reminded her too much of the night she lost Morris. "Metropolitan Police!" Her voice echoed in the tunnel. "Stop where you are, Herrera!" Only the steady drip of water answered. Quinn pulled out her torch, its beam cutting through the gloom. Rust-stained tiles lined the walls, and ancient adverts peeled beneath layers of graffiti. The air carried a metallic tang that didn't match the usual underground must. She descended the emergency stairs, each step precise despite her racing pulse. At the bottom, boot prints in the dust led deeper into the station. But something was wrong. The tracks didn't match the chaos of their chase - these were orderly, purposeful. Like they'd been left by regular foot traffic. Quinn followed the trail, torch beam sweeping methodically. The main platform ahead had been transformed. String lights crisscrossed the ceiling, casting a warm glow over what looked like market stalls. But they were empty now, leaving only hints of their purpose - strange stains on tablecloths, scattered dried herbs, empty glass vials that caught the light. A sound echoed from further down the tunnel - footsteps, and something else. Voices speaking in languages she didn't recognize. Quinn checked her watch - an old habit that helped steady her nerves. The worn leather band was slick with rain. This was the part where protocol said to call for backup. But backup hadn't helped Morris. Sometimes you had to follow your instincts, even when they led you into the dark. She moved deeper into the station, past the empty market stalls. The voices grew louder. A warm breeze carried the scent of incense and something sharper, chemical. At the edge of her torch beam, she caught movement - shadows that didn't quite match the shapes casting them. Herrera appeared at the far end of the platform, his Saint Christopher medallion glinting in the strange light. He wasn't running anymore. Instead, he held something in his outstretched hand - what looked like a small disc of polished bone. "Detective Quinn," he called, his Spanish accent more pronounced under stress. "You don't want to be here. Go back up. File your report. Say I escaped." "You know I can't do that." Quinn kept her torch trained on him, her other hand near her weapon. "Whatever you're involved in, whatever you're protecting - it's not worth throwing your life away." He laughed, but there was no humor in it. "My life? Detective, I lost my medical license because I chose to help people you don't even believe exist. But they're real. As real as whatever took your partner." Quinn's grip tightened on the torch. "What do you know about Morris?" "Only rumors. But if you follow me through that gate-" he gestured to what looked like an ordinary maintenance door behind him "-you'll start to understand. Your choice, Detective. But you'll need this to enter." He placed the bone disc on the ground between them. The voices beyond the door grew louder, and Quinn caught fragments of conversation about prices and trades. The Veil Market. She'd dismissed it as criminal folklore, but now... She thought of Morris. Of the impossible things she'd glimpsed that night. Of the questions that had haunted her for three years. "Last chance," Herrera said. "Walk away, or pick up the token and face what's really out there. But if you come through, you're entering their world. And they play by different rules." Quinn took a step forward, then another. The bone token felt warm in her palm, like it had absorbed the heat of countless hands before hers. She looked up to find Herrera watching her with something like sympathy in his warm brown eyes. "Their world," she said, "has some questions to answer." She followed him through the door, leaving the familiar darkness of London's underground for something deeper, stranger, and far more dangerous. But maybe, finally, she'd learn the truth about what happened to Morris. Even if that truth changed everything she thought she knew about the city she'd sworn to protect.
