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 needled Quinn's scalp, finding the gaps between her closely cropped salt-and-pepper hair. She didn't blink. Her military bearing kept her shoulders square despite the sodden weight of her coat, her left wrist anchored by the worn leather watch that had survived eighteen years of decorated service and three years of unanswered grief. She kept her eyes fixed on the olive-skinned man thirty meters ahead, his short curly dark hair plastered flat against his skull as he darted left onto Lexington Street, his shoes sending up silver sprays from the gutter. Tomás Herrera. Twenty-nine years old. Born Seville. Former NHS paramedic. Current ghost in the system. Quinn's jaw tightened, sharp angles cutting stark shadows in the sodium streetlight. Her shoes struck wet pavement with metronomic precision, echoing off the closed storefronts of Camden's industrial district. She didn't shout Metropolitan Police; she didn't need to waste breath. The chase had started six blocks back outside The Raven's Nest—that distinctive green neon sign buzzing like a dying insect in her peripheral vision before she'd clocked him slipping out the hidden back room of Silas' bar, the one behind the bookshelf. Now the walls covered with old maps and black-and-white photographs were behind her, replaced by concrete and iron, and the metallic taste of pursuit filled her throat like copper wire. Herrera was fast for a medic. He cut right past a closed curry house, his hand momentarily touching the brickwork for balance, and she saw the scar running along his left forearm—white and jagged, a knife attack from his past—flash pale against his sleeve. Around his neck, the Saint Christopher medallion bounced against his chest. Protector of travelers. She wondered if he thought it would help him tonight. Quinn's thighs burned as she accelerated. Three years since DS Morris had stepped into a case with unexplained circumstances and never stepped out. Three years of case files that smelled of ozone and wrongness, of corners of London that existed between the ordnance survey maps. Every lead brought her to men like Herrera—people who treated supernatural patients, who moved in the liminal spaces where the Metropolitan Police feared to tread. She was forty-one years old, five-foot-nine of disciplined muscle and suspicion, and she was done with fear. He disappeared around the corner of a derelict textile warehouse. Quinn closed the distance, her hand brushing her hip where her Glock rested in its holster. Not drawn yet. She had rules. But the rules felt thinner tonight, stretched by the rain and the memory of Morris's empty desk. She rounded the corner. The alley dead-ended at a utility building marked CAMDEN TUNNELS—CLOSED 1972. No Herrera. But a metal door—painted industrial green and rusted at the edges—stood ajar, leading down. Always down. Concrete steps descended into a darkness that swallowed the beam of her Maglite before it could find bottom. Quinn paused. Her watch ticked, audible above the rain drumming the pavement behind her. The last time she'd followed a suspect into underground darkness, Morris had been alive, joking about getting kebabs after the shift. Now she worked alone, chasing phantoms that left traces the department forensics team couldn't catalog—ashes that smelled of vanilla, blood that ran upward, wounds that healed before the camera shutter clicked. She drew her torch in her left hand, gripped her sidearm in her right, and descended into the abandoned Tube station. The air changed immediately. Warmer. Thicker. The smell of London rain—diesel and wet stone—gave way to something older. Ozone and myrrh. The walls were tiled in the cream and green of the Northern Line's abandoned arteries, but the grout between them pulsed with a faint, fungal luminescence that had nothing to do with electricity. Her shoes crunched on the steps. She looked down. Bone fragments, pale and polished, scattered like macabre gravel. The wound of Morris's loss, still raw and unhealed in her chest, drove her downward step by step. Her military precision kept her movements economical, her back straight, her aim steady despite the irrational pressure building behind her eyes. The supernatural origins of his disappearance that she didn't yet understand waited at the bottom of these stairs. She felt it in her teeth, in the way the shadows seemed to lean toward her rather than away. At the bottom, the corridor opened into the station proper. The archway that should have been bricked up according to city planning records gaped like a missing tooth, revealing a platform that extended into impossible space. And beyond it—light. Not electric. Something organic. Flickering blue-green phosphorescence coating the tiles, casting shadows that moved independently of their sources. Herrera stood near the platform's edge, no longer running. His chest heaved, olive skin sheened with sweat despite the chill that should have permeated this deep underground. The Saint Christopher medallion around his neck swung gently, catching the strange light. He pressed his scarred left forearm against his ribcage as he turned to face her, his warm brown eyes reflecting the bioluminescence with an inhuman shine. "Detective Quinn," he said. His accent—Seville, her file said—softened the detective to something almost gentle. "You shouldn't be here." She kept her torch beam centered on his chest, her sidearm lowered but ready at her thigh. She noted the tension in his shoulders, the way his weight balanced on the balls of his feet—not aggressive, but prepared to flee deeper. "Tomás Herrera. You're wanted for questioning regarding unauthorized medical practices. And for running from lawful detainment." "I'm running from what's coming," he said, gesturing vaguely toward the tunnel mouth behind him. "Not you. Never you, Detective." Behind him, the tunnel breathed. Quinn heard it then—the subsonic murmur of commerce, but wrong. Too quiet, too intimate. The rustle of silk that sounded like whispering, the clink of glass containing things that couldn't survive sunlight, negotiations conducted in frequencies that made her back teeth ache. She stepped onto the platform, her shoes grinding against more bone fragments—femurs, ribs, vertebrae polished smooth by countless footsteps. The Veil Market. She'd read the name in Morris's final notes, the ones Internal Affairs had confiscated and dismissed as post-traumatic stress hallucinations. A hidden supernatural black market that moved locations every full moon, selling enchanted goods and banned alchemical substances. A place requiring entry tokens made of bone. Herrera backed toward the tunnel mouth, where the shadows resolved into shapes—stalls draped in fabrics that shifted color when viewed indirectly, vendors with too many joints in their fingers, customers wearing cloaks of living shadow. "Your partner," he said, watching her face carefully, reading her reaction. "Morris. He came here too. Three years ago. He was chasing someone like you're chasing me." Quinn's finger spasmed on the trigger guard. The leather watchband creaked as her wrist tensed, the familiar weight of it grounding her. "You know something about Morris?" "I know he didn't die," Herrera said. "Not the way they told you. Not the way they found the body. But if you cross that threshold, Detective, if you enter the Market without a bone token and without invitation..." He shook his head, rain water—or sweat—dripping from his chin. "You might wish you had his excuse for disappearing. Some doors only open inward." She looked past him. The tunnel opened into a cavernous space that violated the geometry of the abandoned station. Stalls lined curved walls that extended farther than the London clay should have allowed. Figures moved between them—some human-shaped, some wearing the wrong number of limbs, their shadows stretching too long, too angular, reaching toward the ceiling where impossible roots twisted through concrete. Above, instead of electrical conduits, something like bioluminescent vines dripped sap that evaporated before hitting the ground, leaving trails of steam. A guard stepped forward from the shadows—gray cloak, face obscured, hand extended for the entry token she didn't possess. She had no bone token, no invitation. But the guard's eyes, visible beneath the hood, reflected no light. They simply watched, waiting to see if she would break the rules or turn back. Herrera took another step back, merging with the gloom of the entrance. "Last chance, Detective. Go back to Soho. Go back to the Raven's Nest and the safety of walls covered with old maps. Go back to a world where the Metropolitan Police has jurisdiction and the dead stay dead. This isn't your world. This isn't your war." Quinn touched her watch with her left thumb, tracing the worn leather strap that had survived eighteen years. The military precision that had defined her career crystallized into something harder, something willing to walk into darkness without backup, without sanction, without a guarantee of return. Morris had gone in. Morris had never come out. But he had left breadcrumbs, and she was done following them from a safe distance. She holstered her weapon. She wouldn't need bullets where she was going; she'd need resolve, and the willingness to become as much a ghost as the man she pursued. The decision settled over her like the rain had settled over London—inevitable, soaking through to the bone. "I'm not leaving," she said, and stepped forward into the Veil Market.
