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 the back of Detective Harlow Quinn’s neck and slid cold down the seam of her collar. Soho at midnight had a way of pretending it was still bright—shopfronts lit for no one, taxi headlights smearing through wet air—but the alley beside The Raven’s Nest stayed stubbornly dark. The bar’s distinctive green neon sign flickered over the entrance like a pulse refusing to settle. Quinn watched it from across the street, jaw set, shoulders squared, every line of her stance clipped and deliberate. Military precision had never been a choice for her. It was what kept her upright when the world tilted. A man stepped out under the neon and paused as if listening to the rain. Short, curly dark hair plastered to his head. Olive skin turned slick under the light. He kept his face angled down, but Quinn had spent eighteen years learning to read movement before features. The left arm hung a fraction stiff, as if he still remembered old damage. A scar along the forearm, maybe. Around his neck something caught green—metal, round—before it vanished under his shirt. Tomás Herrera. Quinn felt a familiar, sour heat under her ribs. Not certainty. Not yet. But enough. She pushed off the wall and crossed, boots striking shallow puddles. A car hissed past, tyres cutting water into a low spray. She didn’t break stride. “Herrera!” Her voice snapped clean through the rain. He flinched—an instant too late to play innocent. His head came up and for a fraction of a second she caught his eyes, warm brown gone hard with decision. His right hand went to his chest, the reflexive protective press of someone who kept something valuable there. Then he turned. He ran. Quinn swore once, flat and quiet, and ran after him. The street narrowed into a ribbon of wet cobbles between brick facades. The air smelled of soaked cigarette ends and old frying oil. Herrera moved like someone who’d spent time hauling stretchers up stairwells—fast, economical, no wasted sway. He cut left, then right, using corners like knives. Quinn matched him, coat dragging at her thighs, wet hair clinging close to her scalp. Her worn leather watch on her left wrist slapped damp against bone each time her arm drove forward. The world reduced to breath and footfall and the pale shine of Herrera’s back in the rain. He vaulted a low chain, landed, and shot across the mouth of a side street. A taxi honked—sharp, angry—brakes squealing as he slid past its bonnet. Quinn didn’t have his timing; she had weight and authority. She threw a hand up, palm out, and the cab swerved just enough to spare her. The driver shouted something. The rain ate it. “Herrera!” she called again. “Stop! Metropolitan Police!” He glanced back. Not long enough to see her face, just long enough to show he’d heard. His mouth tightened. He pushed harder. Quinn’s lungs burned. She’d kept herself fit, but London’s nights didn’t care about dedication. The streets became slicker, the angles meaner. Soho bled into Fitzrovia, then into wider roads where buses roared past like dark animals. Herrera didn’t slow at crossings. He threaded between vehicles with a recklessness that wasn’t panic; it was urgency. The difference mattered. At the edge of a park, he ducked into a gap in iron railings where someone had cut away a bar. Quinn followed, mud sucking at her soles. Trees shivered with rain, their leaves turning the streetlamps into green smears. Herrera ran along the path without looking back now. He knew where he was going. Quinn’s mind tugged at files, at whispered informant tips, at the unlabelled fear that sat at the base of her throat whenever a case turned strange. Three years ago, DS Morris had walked into an abandoned building with her, joking about the coffee they’d get after. He’d never walked out. The official report used words like structural collapse and unknown assailant. Quinn still heard his last shout in her sleep—cut off, wrong, like a radio dying. There had been nothing natural in the way the air had changed that night. Nothing she could put in a statement without being laughed out of the job. Now Herrera—former paramedic, struck off for “unauthorized treatments,” always hovering on the edge of the same names she couldn’t connect—was running through the rain like he’d done it a hundred times. He burst out of the park and onto a wider road. Camden, by the look of the signage, though the night made everything feel unfamiliar. The buildings here had a rougher face, graffiti bleeding down shutters, the canals and rail lines threading under the skin of the city. Herrera cut down a stairwell that shouldn’t have been open. A Tube entrance, old and half boarded, the kind of thing developers promised to restore and never did. The sign above it was rusted to illegibility. A chain hung loose on one side as if someone had unhooked it minutes ago. Quinn hit the top step and skidded. Cold water ran down into the darkness. The air that rose from below smelled stale, metallic, and faintly sweet—like rotting fruit under iron. She drew her torch and took the steps two at a time. The stairwell spiralled down, walls sweating. Her beam caught old posters peeling into curls, their faces long out of fashion. Herrera’s footfalls slapped below, echoing off tile. Quinn’s pulse pounded in her ears, steady and hard. At the bottom, the passage opened into an abandoned platform. Tracks lay beyond, black and wet, disappearing into tunnel mouths. The ceiling was low enough that the rain’s sound faded, replaced by distant drips and a low murmur she couldn’t place at first. Not trains. Voices. Herrera ran along the platform edge and stopped at a section of wall covered in faded station maps. He pressed his palm to a seam. For a breath nothing happened. Then the wall shifted with a soft grind, not loud enough to be mechanical, more like stone making room for stone. A gap opened, and warm light spilled out—amber and green, like old gas lamps and sickly neon mixed. Quinn slowed, not because her legs wanted to, but because her instincts grabbed her by the throat. Beyond that gap was movement. Shadows crossing light. The murmur resolved into layered speech, too many dialects, too close together. Something laughed—high, brittle. Something else answered with a sound that might have been a voice or might have been an animal mimicking one. Herrera stepped through the opening. Before he vanished, he turned back. His face was sharp with rain and effort, and for an instant he looked less like a suspect and more like a man running toward something he didn’t want anyone else to see. “Don’t,” he said, voice low but urgent. Quinn’s grip tightened on her torch. “Police,” she shot back. “Stop and identify yourself.” His eyes flicked to her left wrist—her watch, maybe, or the way her hand hovered near her belt out of habit. Then his gaze lifted past her, as if checking the platform behind her for someone else. “You have no idea where you are,” Herrera said. “And you do?” His mouth twitched, not quite a smile. More like a grim acknowledgement of a bad situation. “Yeah.” Then he was gone, swallowed by the light. The wall began to shift again, the gap narrowing. Quinn lunged, boot scraping on wet concrete. She jammed her hand into the opening before it could close. The edge pressed hard against her knuckles—cold stone, unyielding. Pain flashed up her arm. “Bloody—” She shoved, shoulder driving into it, and the seam grudgingly widened enough to let her slip through. The warmth hit her first. Not heat exactly, but a thick, living air that carried incense, oil, damp wool, and something sharper that made the back of her throat prickle. Her torch beam looked ridiculous in here, swallowed by lantern light and strings of bulbs hung between old pillars. She stood on the threshold of a market built into the bones of the abandoned station. Stalls had been hammered together from scavenged wood and sheets of metal. Cloth awnings dripped rainwater in slow, steady taps. People moved in tight currents between tables laid with goods that didn’t belong in any legal shop—bottles that seemed to hold smoke, knives with edges that caught light without reflecting it, jars of dark powder, bundles of herbs tied with hair-thin twine. And the faces— Some were human enough. Some were not, though Quinn’s mind resisted the conclusion, trying to force what she saw into categories it understood. A woman with eyes too pale, like milk glass, leaning over a tray of tiny bones arranged in careful spirals. A man whose smile showed teeth too many, too even. A figure in a hood that moved with a slow, gliding grace, their hands long and delicate as spider legs. Herrera was already pushing into the crowd, head down, moving with the confidence of someone who knew the currents and where they broke. Quinn took one step in. Then another. A shape detached from the nearest stall—a stocky man with a shaved head and a coat too heavy for underground. He blocked her path with a casualness that wasn’t casual at all. “Token,” he said. His accent was London, but the word came out like a rule older than the city. Quinn held up her warrant card. The plastic looked cheap in this light, a child’s toy. “Metropolitan Police. Move.” The man’s gaze flicked over the card and back to her face. His eyes were black as wet stones. “Bone token,” he repeated, unbothered. “No token, no market.” Behind him, the murmur shifted. A subtle change in tone, like a flock of birds turning their heads at once. Quinn became aware of attention sliding onto her from every angle. Measuring. Curious. Hungry. Her hand hovered near her cuffs, then dropped. Arresting the doorman to an illegal market was a clean action in a dirty world. But this wasn’t just illegal. It felt… layered. As if she’d stepped not under London, but under something else that wore London like a coat. She searched the crowd for Herrera. Found him for a second—his dark head, his shoulders—then lost him again behind a hanging curtain of beads that clacked softly as someone passed. Quinn’s pulse steadied, oddly, as fear sharpened into focus. This was the moment, she thought. The point where she could turn around, seal this memory in the same box as Morris’s last shout, and tell herself she’d done the sensible thing. Sensible had not brought Morris back. Sensible had not explained why his blood had looked too dark on the concrete, why the air had smelled like pennies and lilacs, why the CCTV had cut out in a perfect circle around the building. She leaned closer to the doorman, voice low enough that it didn’t carry. “Where do I get one?” His gaze slid to her left wrist again. The watch. The way it sat—worn leather, familiar. For a heartbeat, something like recognition flickered there. Not of her, perhaps, but of the shape of her determination. “Not here,” he said, and nodded past her shoulder. Quinn glanced back. Near the threshold, a narrow table sat half in shadow. A woman stood behind it, face hidden by a veil of thin black fabric. Her hands were bare, pale, and in her palm she rolled something small and white. A token. It wasn’t a coin. It looked like a sliver of bone carved smooth, with a hole drilled through one end as if meant to be worn. The sight of it made Quinn’s stomach tighten. The entry requirement, made literal. She turned back to the doorman. “If I take one, I’m in?” He shrugged, the movement heavy, indifferent. “If they let you keep it.” Quinn didn’t like that answer. She liked it even less because it felt true. She looked again, deeper into the market, trying to catch Herrera’s trail. A glimpse of his Saint Christopher medallion flashed at his throat as he shouldered past a stall where a cage of moths beat their wings against wire, their bodies glowing faintly green. He was moving fast. Toward something. Quinn made her choice before she could talk herself out of it. She stepped around the doorman and walked to the veiled woman’s table. The woman’s head tilted, as if listening to Quinn’s footsteps through the wet on her boots. Quinn laid her warrant card on the table. It felt absurd, but it was what she had. “I need a token.” The veiled woman didn’t touch the card. Her fingers kept rolling the bone sliver, back and forth, back and forth, like worry beads. When she spoke, her voice was soft and dry. “Police don’t buy,” she said. “Police take.” Quinn’s jaw clenched. “I’m not here for a bribe. I’m here for a man.” “A man,” the woman echoed, as if tasting the simplicity of it. “Always a man.” Quinn’s mind flashed Morris again—his grin, his patience, the way he’d called her Quinny when no one else dared. She pushed it down. It wasn’t ammunition. It was a wound. “How much?” Quinn asked, and hated the way the word came out. The veiled woman’s hand paused. Slowly, she set the token on the table between them. Bone, smooth, faintly porous. Real. “Something from you,” the woman said. “Something honest.” Quinn stared at it. Around her, the market breathed. Lantern light trembled with the movement of bodies. Somewhere close, a glass clinked. Somewhere farther, something hissed like steam. She could turn now. She could back out, call it in, bring uniforms, flood the entrance— And watch this place vanish, leaving behind only abandoned tiles and dripping tunnels. Herrera would be gone. Whatever he was running toward would stay buried. Whatever had taken Morris would keep its teeth. Quinn reached up and unfastened her worn leather watch. The strap stuck slightly where rain had soaked it. She set it on the table beside the token. The weight of it leaving her wrist felt wrong, like stepping out without a belt. The veiled woman’s fingers hovered over the watch, not touching at first. Then they settled on the leather with a slow, almost reverent press. “Time,” the woman murmured. “Yes.” She nudged the bone token forward. Quinn picked it up. It was warmer than she expected, as if it had been in someone’s mouth. She closed her hand around it, feeling its smooth edge bite into her palm. The veiled woman leaned closer. Through the black fabric, Quinn could just make out the faint shape of lips. “When you find what you’re chasing,” the woman whispered, “don’t assume it stays found.” Quinn didn’t answer. She slid her warrant card back into her pocket, shoved the bone token into the other, and turned into the crowd. The market swallowed her. Voices brushed her ears—bargains made in murmurs, names spoken like threats. A shoulder bumped hers; a hand trailed too close to her coat pocket. She caught the wrist without looking, twisted just enough to warn. A startled gasp. The hand withdrew. Quinn pushed forward, eyes scanning for Herrera’s dark curls, for the flash of his medallion. Every instinct screamed that she was out of jurisdiction, out of depth, out of the world she understood. She went anyway. Somewhere ahead, a shout rose—sharp, urgent—and the crowd rippled like water struck by a stone. Herrera’s voice cut through, strained. “Move!” Quinn broke into a run again, bone token clenched in her fist like a key she didn’t know how to use, and the Veil Market shifted around her as if it had been waiting to see whether she’d chase the truth all the way into the dark.
