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 green neon sign of The Raven’s Nest hummed with a low-frequency buzz that Harlow Quinn felt in her molars. It flickered, casting a rhythmic, sickly light across the rain-slicked pavement of the Soho alley. Quinn leaned into the shadow of a recessed doorway, her closely cropped salt-and-pepper hair damp with the London mist. She didn’t mind the cold. Eighteen years on the force, most of them spent in the gray damp of the Met, had turned her blood to slush. She checked the worn leather watch on her left wrist with a flick of her eyes. 11:14 PM. Across the street, the heavy oak door of the Nest groaned open. Tomás Herrera stepped out. Even from twenty yards, Quinn recognized the silhouette. He stood 5'10", his posture slightly guarded, the collar of his jacket turned up against the downpour. He paused under the neon glow to light a cigarette, the flame of his lighter illuminating his olive skin and the sharp, handsome features Quinn had memorized from a dozen grainy surveillance stills. He took a drag, his eyes scanning the street with a twitchy, practiced caution. He wasn't a world-class criminal, but he was a man who knew he was being hunted. He rubbed his left forearm—the spot where Quinn knew a jagged knife scar ran beneath his sleeve—and began to move. Quinn pushed off the wall with military precision. She didn't rush. She kept her pace steady, her boots clicking softly on the wet stone, maintaining a distance that allowed the ambient noise of the city to swallow her footfalls. Herrera didn't head for the main drags. He ducked into the labyrinthine secondary streets that bridged Soho and Fitzrovia, moving with a surprising, athletic grace. Quinn followed, her sharp jaw set, her brown eyes tracking the swing of his shoulders. She’d lost her partner, Morris, three years ago in a dark room that smelled like copper and ozone, and every lead she’d followed since had led her to the same wall of silence. But Herrera was the crack in that wall. He was the medic for a group of people who didn't exist on any official database, a man who had lost his license for treating things that didn't bleed red. As they neared the outskirts of Camden, the chase shifted. Herrera spotted her. It happened in the reflection of a shop window. He didn't panic; he simply accelerated. He vaulted a low iron fence into a construction site, his boots kicking up mud. Quinn didn't hesitate. She scrambled over the fence, the cold metal biting into her palms, and landed in a crouch. "Herrera! Police! Stop!" her voice rang out, authoritative and echoing against the scaffolding. He didn't stop. He scrambled over a mound of gravel and disappeared behind a stack of plywood. Quinn was older, forty-one now, and the damp air sat heavy in her lungs, but she had the stamina of a woman who ran ten miles every morning to outrun her own ghosts. She rounded the plywood just in time to see him diving down a set of stairs—not a subway entrance, but a service stairwell leading into the guts of an abandoned Tube station. The air changed as she descended. The smell of wet asphalt was replaced by the cloying scent of scorched earth and something metallic, like ancient pennies. The tiles on the walls were cracked and yellowed, weeping a black, viscous fluid. The lights overhead—long-dead fluorescent tubes—flickered with a ghostly, blueish luminescence that shouldn't have been possible. She reached the bottom of the stairs and found herself in a wide pedestrian tunnel. Herrera was fifty feet ahead, his breath coming in ragged gasps that matched her own. He reached a heavy iron gate that blocked the way to the platform. "Tomás, enough!" Quinn shouted, her hand going to the grip of her sidearm. She didn't draw it, but the threat was there in the set of her shoulders. "You’re a paramedic, not a runner. Let’s talk about the people you’ve been helping. Let’s talk about what happened to Morris." Herrera stopped. He turned, his chest heaving, his dark brown curls plastered to his forehead. He looked at her with a mixture of pity and terror. He reached into his shirt, pulling out a Saint Christopher medallion that hung around his neck, clenching it in his fist. "You shouldn't have followed me, Detective," he said, his voice echoing in the hollow space. "This isn't your world. You still think the law matters down here." "The law matters everywhere," Quinn snapped. "Who are you meeting, Herrera?" "I'm not meeting anyone. I'm going to work." He reached into his pocket and pulled out something small and white. He held it out toward a figure Quinn hadn't noticed before—a tall, emaciated man standing in the shadows of the gate, draped in a coat of tattered black feathers. The figure in the shadows held out a hand. Herrera dropped the object into it—a bone token, carved with symbols that seemed to writhe in the dim light. The gate groaned, sliding open on tracks that hadn't seen grease in half a century. "Wait!" Quinn lunged forward, but Herrera stepped through the threshold. The space beyond the gate wasn't a train platform. It was a cavernous hall, lit by thousands of floating lanterns and the braziers of a hundred stalls. It looked like a medieval bazaar transposed onto a Victorian ruin. This was the Veil Market. Quinn had heard whispers of it in the delirious ramblings of C-wing informants, but seeing it was a physical blow to her senses. The air was thick with the smell of incense, raw meat, and something that smelled like a thunderstorm. Herrera disappeared into the crowd—a surging mass of figures, some clearly human, others wearing masks that were far too lifelike to be plastic. Quinn stood at the gate. The man in the feathered coat turned his gaze toward her. He had no eyes, only polished obsidian spheres that reflected the flickering lanterns. He held out his hand, palm up, waiting. The logical part of her brain, the part that had served eighteen decorated years in the Metropolitan Police, told her to turn around. This was the unexplained. This was the source of the rot that had taken Morris. If she stepped through, there was no guarantee the world she knew would still be there when she returned. She looked at her watch. The second hand was ticking backward. Quinn felt the weight of her badge in her pocket, a piece of tin that felt suddenly, absurdly light. She thought of Morris, and the way his eyes hadn't been able to focus in those final moments, fixed on something she hadn't been able to see. "I don't have a token," Quinn said, her voice steady despite the hammering of her heart. The gatekeeper tilted his head, the feathers of his coat rustling like dry leaves. He leaned closer, the obsidian eyes scanning her. "You have sorrow," he rasped, his voice sounding like two stones grinding together. "Sorrow is a currency here." He stepped aside, a silent invitation into the dark. Quinn took a breath, the air cold and sharp as a razor in her throat. She gripped the worn leather of her watch strap, centering herself in the physical reality of her own body, and then she stepped across the line. The gate clanged shut behind her, the sound final and heavy, echoing through the subterranean market as Detective Harlow Quinn walked toward the golden light and the shifting shadows of things she was finally ready to understand. The chase wasn't over. It was just changing shape. She watched Herrera’s dark head bobbing through the crowd near a stall selling jars of glowing blue liquid, and she broke into a run, her boots finally hitting the floor of a world she had spent three years trying to deny. She was no longer just a detective; she was a trespasser in a place where the sun never rose. And as she pushed past a merchant selling dreams in silver vials, Quinn knew she wouldn't leave until she had the names of everyone who had watched her partner die.
