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 rain came hard enough to erase the city's finer lines. Puddles swallowed the glow from traffic lights and the green neon of the Raven's Nest split itself into molten streaks along the cobbles. Harlow Quinn moved through the smear like a knife through oil, shoulders compact, chin down. The collar of her coat kept the worst of the cold from her neck; the leather watch hugged her wrist, cold and familiar. Her breath came out in short, regular bursts. She liked to keep the rhythm. It steadied her hands. He was already three steps ahead when she saw him—a pale face, dark hair plastered flat by the rain, the black coat that did nothing to conceal a guilty hunch. He emerged from the bar's doorway in the same instant she did. The Nest's green sign hummed overhead, casting a jaundiced light on his jaw. For a fraction of a second their eyes met, and she saw the calculation there: a way out, a route known to a dozen hidden hands. "Stop!" she called. Her voice cut through the rain, sharp. The man didn't bother to look back. He ran. Quinn didn't lose the moment to think. She moved after him, boots slapping wet stone. Rain stitched into her eyelashes; water ran in a line down her temple and into the collar of her coat. Steam rose from a grate as she passed, ghosting over a discarded flyer for a show that had closed weeks ago. Her feet took the route soldiers had taught her: steady, efficient, never sprawling. She closed the gap by forcing the man into a narrower street—no crowd to hide in, only brick and shuttered windows and the smell of wet cigarette paper. He turned into an alley the width of a book. Trash bins clanged underfoot. Quinn's shoulder clipped a rusted drainpipe and she didn't slow. He ducked through a swinging door half off its hinges, into the Nest's back entrance. The bar swallowed him. So much for a simple arrest. Inside, the air was thick with peat smoke and something older: dust, varnish, the tang of whiskey steeped into wood. Black-and-white photographs stared from the walls, their faces frozen in permanent surprise. Old maps crossed in the frames, routes and coastlines sketched in ink that had browned with time. The bar's back was a wall of bookshelves knit tight with spines whose titles meant little to Quinn—travelogues, maritime logs—but the man moved as if he knew them all. He reached a point where the books seemed more of a screen than a library and slid his hand along the row until the spines made the softest click. A panel swung inward. The hidden room smelled different: dried tobacco, cheap perfume, the copper note of metal. A table sat low, covered in maps and scraps of paper and the kind of ledger that always found its way into criminal hands—neat columns, folded margins. Candles guttered in holders and threw the walls into new angles. At the far side, a hatch gave onto a narrow stair, iron rungs slick with damp. The man moved like smoke through that door. Harlow stopped at the threshold. Everything military in her wanted to call in backup, seal the exits, wait with procedure. The last time she had operated on patience, DS Morris had waited for backup in a place the paperwork insisted would be safe. He was dead now, gone three years and never accounted for, his absence a stubborn bruise she couldn't scrub away. The official line had said an accident. Her instincts—private and unpolished—said otherwise. She thumbed the leather band of her watch and felt the small, steady pulse of the timepiece against her wrist. It was a nonsense ritual she kept when choices were not about the technicality of law but about the small, personal codes that mattered. Her jaw set. Military precision had taught her a simple calculus: secure, then proceed. But the Nest's staircase offered no time, and the man at the bottom meant questions she could not live with unanswered. "Quinn?" A patron's voice, muffled, from somewhere beyond the bar meant nothing. The bartender's hands were busy. No one moved to stop her. She ducked through the bookshelf and let the panel slide shut behind her with a soft, closing click that sounded much louder in the room. The stair took the rain from her coat and sucked it away into a thick, subterranean cold. Iron rang under her palms. Droplets fell from overhead and spattered on her gloves. The light thinned as she descended; the sound of the city peeled off, reducing to something like a held breath. At the bottom, a door gave way onto a platform that smelled of old trains and wet stone. Tiles peered from beneath a film of grime. An archway led into darkness that wasn't quite absence—faint glows, the smear of other lights, the low chorus of human voices and bargaining. She knew what the rumors called it if not the reality: the Veil Market. A name that sounded like a story told to keep the curious away. She had put it down as hearsay. A part of her, the part that held Morris in a small dark shape, had suspected otherwise and had watched the Nest for weeks precisely because of that whisper. Bones were required for entry, the gossip said. Tokens carved from bone and etched into a language Quinn didn't know. The idea of gatekeepers accepting femurs like coins and letting the city trade in enchanted trinkets and banned alchemical vials had been framed as the sort of thing officers laughed at to keep their hands steady at night. Jokes smoothed over things that made you bleed in private. Harlow felt the joke as a thin skin over a more dangerous truth. She hesitated because she did not have a token. She checked instinctively: pockets, inner breast of the coat—no bone, no charm, no coin with the right teeth on it. The stairs had spat her out into a place that answered to a different currency. The man she followed stood a few feet away, under a lantern wrapped in coloured glass. He was trading with someone whose face she briefly caught—a thin woman with hair pinned up under a kerchief, hands swift, eyes like a cat's. She gave the man a small, palm-sized object, white and rough at the edges. The man pressed it into his palm like a prayer, and the woman's lips moved. No one checked under his clothing. No guard stepped in front of him and barred the way. The rules here were subtler than the ones she knew. It was a market in the truest sense: stalls pitched from tile and stone, tables patched together with rope and old signage. Candles burned behind jars that smelled of herbs and iron. A man in a coat with sleeves too narrow for his arms sold glass phials that glittered with a light that seemed to breathe; a boy hawked cards that flipped through themselves when you blinked. Voices rose and fell in languages she knew and some she did not. A faint, under-layer thin as breath, like the scent of old bones and lavender, threaded through it all. The man she pursued moved deeper into the market without noticing the watchful tilt of many heads. He slipped between a vendor of charms and a stall carrying tangled lengths of metal—things that caught the light and made it sound crooked. Harlow followed, keeping to the shadows that the cramped market offered. She had to be careful. One wrong step, one sudden show of badge in this room, and every transaction could turn into a knife in the dark. This wasn't about law as it appeared in code books; this was raw and old and fragile. She was alone, and the echo of that solitude had a hard weight. A voice as smooth as coal slid across the air. "No bones, no entrance," someone said, and the words seemed to come from everywhere and nowhere at once. Then a laugh, small and private, like two people sharing a dangerous secret. She stayed where she was. People watched, but police were not the sort of spectacle they wanted. They tolerated her because curious danger was a useful thing to observe and then let go. Still, a hand brushed deliberately along the rim of a stall; a vendor's eyes narrowed like slit shutters. Her feet moved by muscle memory, not bravery. She kept the man in sight until he stopped at a shadowed alcove and exchanged the bone token for something tucked into the seam of his coat—a small folded thing that smelled like smoke. He turned, as if to leave, and Quinn stepped out of the shelter of a stall and called his name before she thought better. "You'll make a mistake," she said. Her voice was low. People looked up; a conversation paused. He flinched, and for a hair of a second, his face opened into something like recognition. Then he smiled, and it was all wrong—too friendly, too quick. "You'll get yourself more than a mistake," he said back. The words were clipped, measured. He took a step that would bring him between two vendors and away from her. She could have shouted for backup. She could have run back up the stairs, called the team, documented the whole thing, told herself the market would still be there tomorrow. Those procedures would have been the safe thing. The dead weight of Morris, of what had happened to him in places that moved and wore new names, who had been "accident" and then "unsolved," pushed against the standard operating manual like a joint that wanted to come apart. She thought then of the ledger on the low table in the hidden room—the charts and folded margins. The names she had seen on the lists. They were small people making small trades, and yet something about those pages felt like a map with a single route marked. She tasted iron at the back of her throat. The watch on her wrist ticked, a small irrelevant thing in a place that kept its own time. Military training gave her one more tool: risk assessment. This was a variable she could control only by walking into it. Quinn moved. She kept the man's distance, gave the market casual space, and let herself become a shadow among others. Her shoulder brushed a woman with silver-streaked hair who smelled of lemon peel and old coins; she watched the woman's hands as if reading them for lies. The man she followed shrugged off the token when he reached a short curtain—two strips of fabric stitched together and hung across an arch. He pushed through and the curtain swallowed him like a throat. The market's chatter fell into a thin seam of noise. Harlow's breath fogged in front of her. She paused at the fabric and thought of the office, of the neat forms and the time taken to tape off a scene and fill out evidence logs. She thought of Morris's smile the last time she had seen it, a small crooked thing when they argued about procedure. She thought of the ledger, the map on the bar wall, the green neon sign outside like a beacon in the rain. She thought of all the times she'd folded small risks into the jacket of a decision and found them harmless but for one that had not been. The world on the other side of the curtain might have bones for money. It might have men who traded in mourning. It might have doors that once closed did not open again. But answers had teeth. They did not wait politely for forms. They bit if you came near. She pushed the curtain aside. The space beyond smelled of things long kept in jars—poppy and ozone and the metal of old coins. A table was set in the center, and there the man she had chased squared his shoulders. Across from him sat a figure like a smudge of darkness in the half-light, hands folded over a dish into which the man put his fingers and withdrew them trembling. Whatever changed there, it did so with the quiet certainty of ritual. Eyes in the room turned toward her as one organism swivels. None of them were kind. None of them were surprised necessarily—curiosity here had teeth, and they'd been watching the Nest longer than she had. A woman at a stall bared her teeth at the newcomer with a movement barely perceptible. Someone laughed that was more like the click of a lock. "You're out of your depth, detective," a voice said. It came from close at hand. Harlow turned and saw a man leaning against a post, a small scar at the corner of his lip. He held nothing in his hands, but his posture spoke of long practice reading people who were unsteady. "I am not out of anything I can finish," she said. Her voice was careful, rehearsed. She had learned in the field to sound like the person sure of themselves even when they were not. The market hummed all around them, a living thing with teeth. The man with the scar smiled. "You know how to ask for things with a badge," he said softly. "But here—here it is not about what you can demand." Badge or not, she couldn't demand entrance to truths this thin. She could break rules, though. She had before. She had lost a partner for daring beyond the roster's safe edges. That memory burned like an ember. It made her cautious but not paralyzed. Harlow watched the man she'd chased as he rose from the table. He held something in his fist—the token, its edges rough, white in the candlelight. He tucked it into a hidden fold in his coat like a secret. He walked past her with a nod, and in the motion something slipped loose: a scrap of cloth, a small paper, a corner of an envelope. She could turn back now. Sign the forms, show the ledger to authority, build a paper path and follow it until someone with jurisdiction took interest. Or she could bend low and pick the scrap from the floor and see what lay written there before the scrap vanished into someone's ledger or memory. It was a small decision made of small things. It folded into her the way a single stitch sets a hem for a whole garment. Harlow reached down. Her fingers closed on paper that smelled of smoke and rain and the tang of copper. The words were in a cipher she did not know, but there was a name—one she recognized from the ledger back in the hidden room. It was not hers to read, but neither was it safe to leave unturned. Her jaw tightened. She looked up. Faces watched. The market’s murmur swelled into an expectant hush. The man with the scar lifted his hand, slow as a man who had known patience. She slid the scrap into her pocket like contraband. The decision had been made. She stepped deeper into the room. The market's lights caught on the edge of the token in the man's coat as he moved away, and for a breath she saw, in one small flash, everything she would have to give up to follow: quiet evenings that were not haunted, reports that closed cleanly, the easy company of fellow officers who did not know how far down this slope twisted. She thought of Morris again, not with accusation but with the weight of a promise she had made to herself to know the truth of what took him. "You're meddling in things you can't mend," the voice with the scar said. "Maybe," she said. "But I'm willing to try." That was the choice—the sound of a woman who had decided that answers were worth the danger. The market seemed to breathe and accept her as if it had been waiting for someone stubborn enough to cross its thresholds without a token and with a badge hidden like a lie. Somewhere deeper in the arches the rain kept up its soft hammering. Outside, the neon of the Raven's Nest hummed on through the night. Quinn's shoulders tightened. She kept her hand in the pocket where the scrap lay, and she moved through the market with the same controlled stride she'd used to chase the man from the street. Each step took her further from the light she knew and closer to the one she did not, but the ledger and Morris and the cold, honest tick of her watch made it plain: she would follow.
