You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

Rain hammered the pavement. Neon bled across slick asphalt. Detective Harlow Quinn sprinted beneath a dripping awning, her leather watch pressed against cold skin as she checked the seconds. Brown eyes tracked the figure ahead—slim, hooded, darting through the storm-soaked night. A burst of thunder rattled the windows of The Raven’s Nest. Green neon signed welcome and warned: Silas’ bar offered refuge, secrets. She skirted the entrance, boots squelching, ignoring the low hum of jazz that leaked into the street. No time for comfort. “Stop!” she barked, voice swallowed by water and wind. Her words echoed off brick walls. The suspect hunched forward, shoulders tight. The coat’s hood slipped just enough to reveal dark curls plastered to a pale forehead. A flash of vulnerability. Quinn limped — a phantom twinge in her right knee reminded her of last month’s falls. She shoved it away, military precision driving each stride. She pushed past a row of shuttered shops, the rain drumming on their metal doors like machine gun fire. Every glare of a passing taxi headlight cut through the dark. A side alley yawned ahead. The suspect dove in, ankle twisting on scattered debris. Quinn caught a flash of a bone token—small, carved, white against the coat. She recognized it from the file on the Veil Market. The black market that thrummed beneath London’s skin. She leapt the low brick wall and scrambled after. The alley narrowed until brick loomed either side. Water pooled at her ankles. She lunged, fingertips grazing the suspect’s collar. The coat slipped free. The suspect turned, panic twisting lips. “Quinn.” Her name drifted in the air, distant, fragile. The suspect’s voice cracked. Heart hammering, she raised the badge clipped to her belt. “You’re coming in.” No fear. Just order. A quick step, and the suspect hurled the token at the back wall. Bone edge bit into the mortar. It slid down two bricks, then stopped. A soft click snapped. A panel shifted. A hidden door swung inward, revealing a spiral staircase swallowed by darkness. Quinn’s pulse thudded against ribs. She caught her breath. Rain dripped from her hair in fine streams. She squared her shoulders, toes at the threshold. “Gonna regret that,” the suspect muttered and vanished down the steps. Quinn stayed on the landing for a heartbeat. Wind gusted through the grate above, whipping her salt-and-pepper bangs across her forehead. She tapped her watch. Seconds ticked away. She recalled DS Morris, partner lost beneath strange forces. She didn’t know what lurked here. But she wasn’t leaving a suspect to slip into the unknown. Rain pounded the entryway behind her. She stepped forward, boots crunching down stone stairs slick with runoff. Each footfall echoed deeper into the earth until the roar of the storm faded, replaced by dripping and distant murmurs. She flicked on a slim LED torch. The beam carved a path through damp stone walls, slick with moss. Ancient tiling crumbled. A stale, coppery scent rose from the floor. Quinn inhaled, mind alert. She descended faster, back pressed against the curve, torch dancing ahead of her. At the bottom, the space opened. Arches rose on either side, framing stalls and tables heaped with oddities: jars of writhing toxins, bones etched with runes, vials that glowed pale green. A dozen figures flitted between them—hunched forms, silhouettes with elongated limbs. Quinn’s torch caught the gleam of scales, the flash of feathered wings. A laugh cracked through the gloom. A pair of clawed hands hefted a black satchel. The owner glanced up: a tall, gaunt figure with jade skin and eyes like chipped glass. It met her gaze, teeth bared in a grin half-mock, half-welcome. “Detective,” it purred. “Shopping at midnight? How…predictable.” Quinn leveled the torch. “Where’s my suspect?” The creature tilted its head. It tucked the satchel under a jam of garments that looked too fluid for fabric. “He left in a hurry. Excuse the market’s inconvenience.” Harlow scanned the stalls. Flickering lanterns outlined other vendors: a dwarf with a braided beard forging metallic leaves that hummed, a woman draped in nets spinning spider-silk strands. The air held the scent of burning lavender, and something beneath it—smoke that tasted like despair. A cart rolled by, wheels scraping stone. The stallholder—an ivory-skinned man with no mouth, just smooth flesh where a grin should be—pushed a mountain of bone tokens. She stepped closer, footsteps echoing. Each token looked different: carved skulls, twisted horns, delicate feathers. The detective’s pulse twitched at the memory of the one she’d seen. “You see this,” Quinn called to the faceless man, pointing. “That token knot open the wall. Someone used it.” He lifted a hand, no expression. “Many come seeking passage. Few survive the price.” Quinn’s jaw tightened. No mercy here. She swept her torch left, caught sight of a dark column at the far end. Shadow clung thicker there, like a wound. Figures melted into that void—one of them could be her suspect. Footfalls pounded behind her. She spun. The jade-skinned creature crept close, voice low. “The tunnels here lead anywhere. The next turn might spit you out on the Thames riverbed or drop you straight into the Deep Cellars. Are you sure you want to go on?” Quinn flicked water from her brow. “Crime scene. Witnesses. He stole from the market’s vault. I’m retrieving evidence.” The creature’s grin curved wider. “A dangerous errand without license. They don’t take kindly to policing their own.” Quinn leveled her torch. “I don’t fear dangers I understand.” Jade-skinned lips curled. “Pride before a fall, detective.” It melted back into the crowd, satchel creaking. She pivoted back to the column. Torch beam trembled. She saw footprints in the dust—small, pointed shoes. Victim of haste. The air shimmered like heat. A voice rasped from the gloom. “Detective Quinn.” She froze. Heart spiked. The voice carried a foreign accent—soft, precise. Warm brown eyes floated into view, framed by damp curls and a wounded forearm scar. Tomás Herrera. “Herrera,” she breathed. He held out his hand. Saint Christopher medallion glinted at his throat. “Follow me. You’re off the books now.” She studied him. Remembered how he patched wounds beyond normal healing, and then lost his licence. “Medicine won’t help what’s down here.” He flashed a quick smile. “You don’t know that.” He darted past her, fluid motion. “This way.” Rain dripped from an overhead pipe, pooling at the edge of a grate. Herrera hopped onto it, gave a nod. Quinn followed. They ducked beneath a wall of iron bars, sprinted through a tunnel where brickwork glowed red from lanterns overhead. Her lungs burned. She stoked her torch. The tunnel delivered them to a pit of water thirty feet across. A rickety footbridge spanned it, planks swaying. Voices echoed beneath the surface, clinking chains. Something shifted in the dark water, ripples widening. Herrera paused, breathing steady. “No turning back.” She looked toward the market’s bustle behind them, then at the yawning black below the bridge. Quin’s leather watch caught the lantern light. She flicked it off. Darkness felt safer. No distractions. Her pulse steadied. The unknown wasn’t invitation; it was choice. She squared her jaw. “Show me the way.” He inclined his head and stepped onto the first plank. It creaked. Water gleamed beneath. Quinn followed. Wood bowed under weight, threatening to snap. Above, a lantern snapped, flame guttered. Shadows lunged. Her torch swung to catch a shape—a winged creature swooping close. Quinn raised her arm, and the creature soared back, screeching. A plank cracked. Herrera yelled, balancing on one foot. She lunged, caught his shoulder before the wood splintered entirely. They landed hard on the next plank together, then the next, until both feet found solid stone on the far side. They didn’t pause. They sprinted up a short flight of crumbling steps into an empty platform. Iron tracks disappeared into black, and a single sign read Camden Road. No trains. Curtains of water from a broken pipe dripped onto rusted rails. A rustle behind the tunnel’s mouth made her whip around. The suspect stood there, hood down now, face wet. Fingers clutched the bone token, backlit by the stairwell’s dim glow. His eyes widened, meeting hers. No fear this time. Determination. Quinn raised her torch. “End of the line.” He took a step forward. “You have no idea what you’re chasing.” Distant laughter rolled through the tunnel, alien and amused. She glanced at Herrera—he kept his distance, medallion shining like a talisman. On her left, the stairwell gaped. On her right, the market’s exit had sealed behind them. Rain’s drumming above. Neon light lost forever. She blinked, weighing the darkness of the tunnel against the city she knew. Fury and curiosity warred in her chest. Her jaw tightened. She flicked the torch off, plunging both of them into darkness. The world narrowed to the steady hum of the rain above, the suspect’s ragged breath, and the beating of her heart. She stepped forward. No turning back now.
