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 over Camden didn't just fall; it dissolved the city into a grey, shivering blur. Detective Harlow Quinn stepped out of her unmarked sedan, her boots finding purchase on the slick pavement with a heavy, rhythmic click. She didn't bother with an umbrella. The moisture clung to her closely cropped salt-and-pepper hair, turning the grey strands into silver wires, but she hardly felt the chill. Within the Metropolitan Police, Quinn was often likened to a piece of flint—hard, grey, and capable of sparking if struck the wrong way. She checked the worn leather watch on her left wrist. 03:14. She was late, but the dead weren't going anywhere. "Quinn! Over here," a voice called out from the yawning mouth of an abandoned Tube entrance. It was DI Miller. He stood under the rusted overhang, huddled in a heavy trench coat that made him look like a sodden pigeon. He flicked a cigarette butt into the gutter, where the water swallowed it whole. Quinn didn't offer a greeting. She simply nodded, her sharp jaw set, and followed him into the dark. They descended a flight of stairs where the tiles were slick with a decade’s worth of grime and subterranean condensation. The air changed as they went deeper, losing the scent of diesel and rain, replaced by something metallic and ancient. This was the threshold to what the street-level informants called the Veil Market, a place Quinn had heard whispers of for months but never seen. It wasn't on any official map, yet here they were, deep beneath the Camden crust. "Uniform found the gate open," Miller said, his flashlight beam dancing across graffiti that looked less like art and more like warnings. "We’ve got one male decedent. Middle of the tracks. It looks like a classic turf war, Quinn. Probably the same crew that’s been running the synthetic op out of King’s Cross." Quinn didn't answer. She was observing the walls. The deeper they went, the more the architecture seemed to shift. The standard Victorian brickwork of the London Underground gave way to stone blocks that looked older, dryer, and etched with faint, swirling patterns that the eye struggled to hold. They reached the platform. It was bathed in the harsh, artificial glare of police floodlights. In the center of the tracks lay a body, contorted in a way that suggested a fall from a height the low ceiling didn't provide. "See?" Miller pointed a gloved finger. "Blunt force trauma. Maybe thrown from a moving maintenance car. We found some residue on his jacket—probably some new high. The kids are calling it 'Aether' or something equally ridiculous." Quinn approached the edge of the platform with military precision, her eyes tracking every inch of the scene. She didn't see a turf war. She saw a man whose clothes were pristine except for the way they had been scorched at the seams—not by fire, but by something that had turned the fabric to white ash without burning the skin beneath. "The residue isn't drugs, Miller," Quinn said, her voice a low, raspy alto. "Then what is it? Starch?" Quinn knelt, ignoring the protest of her knees. She pulled a pair of nitrile gloves from her pocket and reached toward the man’s cooling neck. Her fingers brushed a small, hard object tucked into the collar of his shirt. She pulled it free. It was a small brass compass, its casing heavy with a thick patina of verdigris. It felt impossibly cold through her gloves. The face wasn't marked with the cardinal directions of a normal navigator’s tool; instead, it was etched with strange, protective sigils that seemed to shimmer under the LED floodlights. "Found a trinket, did you?" Miller asked, leaning over her. "Probably worth a few quid at a pawn shop. These Camden types love their steampunk garbage." Quinn ignored him. She watched the needle. It didn't point North. It didn't even point toward the metallic rails of the Tube. It spun in a slow, hypnotic circle, then jerked violently toward a shadow-drenched alcove at the far end of the station. "Stay here," Quinn commanded. "Harlow, the techs are still—" "Stay here, Miller." She stood and walked toward the alcove, her hand instinctively resting on the grip of her sidearm. She reached the edge of the light’s reach and flicked on her own torch. The beam cut through the darkness, illuminating a woman huddled against a stack of crates. The woman jumped, shielding her green eyes from the glare. She was young, maybe mid-twenties, with a wild mane of curly red hair and round glasses that had slipped down the bridge of a freckled nose. A leather satchel, bursting with what looked like ancient, leather-bound books, was clutched tightly to her chest. "I didn't do anything," the woman whispered. Her hand went to her left ear, nervously tucking a stray red curl behind it. "I was just... I was looking for the archive. I have a permit." Quinn kept the light steady. "Your name?" "Eva. Eva Kowalski." "And what brings a research assistant from the British Museum to an abandoned Tube station at three in the morning, Ms. Kowalski?" Eva blinked, her eyes darting to the brass compass Quinn still held in her left hand. "You... you shouldn't be holding that. Not without a grounding charm. The resonance is—" She stopped herself, her freckled face pale. "I was just looking for a specific text. A ledger. The Market was supposed to be here tonight." "The Market," Quinn repeated. She stepped closer, her taller frame casting a long, intimidating shadow over the girl. "You’re talking about the Veil Market. Enchanted goods. Banned substances." "It's just history to me," Eva said, her voice trembling but her gaze lingering on the compass. "That device you’re holding... it’s a Veil Compass. It’s attuned to rifts. If the needle is jumping like that, it means the door didn't close properly. That man on the tracks? He didn't fall. He was caught in the snap-back when the Market moved." Quinn felt a phantom ache in her chest, the same cold sensation she’d felt three years ago when she’d found DS Morris’s car empty on an ivy-choked road in Kent. No blood, no struggle, just a lingering scent of ozone and a sense that the world had folded in on itself. She looked back at the body on the tracks. Miller was busy talking to a forensics tech, laughing at some joke. They saw a victim of a mundane crime. They saw the world as it was supposed to be—orderly, explainable, boring. Quinn looked back at Eva. "The needle is pointing at you, Ms. Kowalski." Eva’s hand flew to her hair again. "It’s not pointing at me. It’s pointing at the satchel. I have... I have a few items in here. Research materials." Quinn reached out and took the satchel. It was heavy, smelling of old vellum and something sharp, like crushed mint. She didn't open it. Not yet. She knew the protocol. She should arrest this girl, bag the books, and turn the compass over to the evidence locker where it would be tagged as 'Item 2004: Brass Compass (Broken).' But Quinn knew what happened to evidence that didn't fit the narrative. It disappeared. Just like Morris’s case file had been 'misplaced' by the Super within a week of his disappearance. "Miller!" Quinn called over her shoulder, her voice echoing off the vaulted stone. "Yeah?" "Tell the techs to focus on the residue on the tracks. I’m taking this witness back to the station for a formal statement. She’s a local vagrant, caught her trespassing." Eva looked up at her, stunned. "I'm not a—" Quinn’s grip on the girl’s arm was firm, but not unkind. "You're going to keep your mouth shut, Eva. You're going to walk out of here, and you're going to tell me exactly how this compass works, and why it's pointing toward a rift that shouldn't exist." She turned the compass over in her hand. The patina felt like scales under her thumb. The needle had stopped spinning. It was now locked firmly on a point somewhere behind them, deep in the tunnel where the shadows seemed to pulse with a life of their own. "Three years," Quinn muttered to herself, her jaw tightening. "Three years of looking for a ghost." "He was your partner, wasn't he?" Eva asked softly, her green eyes wide behind her spectacles. "The man you're looking for?" Quinn didn't answer. She didn't have to. She adjusted her watch, the leather creaking in the silence of the station, and led the girl toward the surface. The rain was still falling, but for the first time in a long time, Harlow Quinn felt like she finally had a heading.
