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.

Detective Harlow Quinn ducked under the hastily erected yellow tape, the chill of the abandoned Tube station seeping into her bones despite the thick wool of her coat. The air hung heavy with the metallic tang of old rain and something else, something acrid and unsettling like burnt sugar. Her worn leather watch, a constant, steady weight on her left wrist, confirmed the time: 03:17. The call had come in an hour ago, a silent alarm tripped at this forgotten junction beneath Camden. Nobody ever came down here anymore, not unless they had a very good reason. Or a very bad one. Her sensible boots crunched on grit and shattered glass as she surveyed the scene. A single, stark pool of darkness marred the grimy platform, the chalk outline of a body stark and unforgiving under the beam of her flashlight. Forensics had already been through, their sterile procedures a stark contrast to the decay surrounding them. Still, something about it snagged at her. The victim, a young man according to the preliminary report, a runner for one of the area’s shadier import businesses. Found by a passing vagrant. Tragic, but hardly unusual for this part of the city. Except the evidence didn’t fit. “Fancy meeting you here, Detective,” a voice chirped from the shadows. Harlow’s hand instinctively tightened on the butt of her service weapon. She swung her flashlight beam towards the sound, catching a flash of round spectacles and a nervous puff of curly red hair. Eva Kowalski, occult researcher and Aurora’s childhood friend. What was she doing here? “Kowalski. This is a restricted area. How did you get in?” Harlow’s voice was low, clipped, each syllable precise, carrying the military precision of her bearing. Eva offered a small, apologetic smile. “The guard downstairs was… indisposed. Said something about a sudden onset of existential dread. I found an unlocked service entrance with a rather fetching symbol carved into the frame. Might I suggest your team dust it for prints?” Harlow ignored the jab, her gaze sweeping back to the chalk outline. “The victim. You know him?” “No. But I know this place,” Eva said, gesturing vaguely with one hand, the other tucked nervously behind her left ear, a habit Harlow had noted the few times they’d crossed paths. “This is the Veil Market. Or it was. They’re supposed to move locations every full moon, but sometimes… sometimes they get sloppy.” Harlow’s jaw tightened. Occult symbols, black markets, ‘sloppy’ supernatural occurrences. This was precisely the kind of thing she’d been warned about, the kind of rabbit hole that had swallowed her partner, DS Morris, three years ago. Unexplained circumstances. Supernatural origins. Words that still tasted like ash in her mouth. “The Veil Market is a myth, Kowalski. A fairy tale for conspiracy theorists.” “Is it?” Eva’s green eyes, magnified by her glasses, glinted in the dim light. “Because that ‘victim,’ as you call him, had a rather unique item clutched in his hand when the vagrant found him. A small brass compass. Tarnished, with some sort of verdigris patina. And the needle,” Eva paused, her voice dropping to a near whisper, “it wasn’t pointing north. It was spinning madly. Pointing towards the… well, towards the other side, I suppose.” Harlow straightened, her flashlight beam cutting a sharp line across Eva’s face. “Another side? What are you talking about?” “Supernatural rifts. Portals. Places where the veil between worlds thins,” Eva explained, her voice gaining a scholar's certainty. “This market is known for dealing in such things. And for tools to navigate them. A Veil Compass, they call it. Crafted by a Shade artisan, if the whispers are to be believed. Designed to point towards these… anomalies.” Harlow’s gaze returned to the chalk outline. A compass. The initial report hadn’t mentioned a compass. It spoke of a single stab wound, clean, precise. Too clean for a street fight. And no weapon found. She walked closer, her flashlight beam dancing over the grimy concrete. There was no blood spatter beyond the immediate vicinity of the body. No sign of a struggle. Whatever had happened, it had been quick. And quiet. Too quiet. “The ME said it was a singular stab wound,” Harlow stated, her voice flat. “Clean. Almost surgical.” “Perhaps,” Eva conceded, her gaze drifting towards the far wall of the platform, where a section of tiling seemed to be peeling away, revealing a dark, damp void behind it. “But the energy readings… I brought a little something with me.” She rummaged in her battered leather satchel, pulling out a small device that hummed with a faint, ethereal light. “The residual energy here is… significant. And it’s concentrated. Not from a wound.” Harlow frowned, watching the needle of Eva’s device flicker erratically. It certainly wasn’t standard police issue. “What are you measuring?” “Ley lines. Foci. Places where the fabric of reality is… stressed,” Eva said, her freckles standing out on her pale skin. “And there’s a very strong concentration behind that wall.” Harlow walked towards the peeling tiles, her flashlight beam probing the darkness. She could hear a faint, rhythmic dripping from within. And the air here was colder, far colder than anywhere else on the platform. She crouched down, examining the edges of the compromised tiling. It looked as if it had been deliberately dislodged, the mortar chipped away with something sharp and metallic. Not the work of a vagrant scrabbling for shelter. “This isn’t a stab wound,” Harlow murmured, her mind racing, piecing together the disparate fragments of information. The unusual location, the impossibly clean wound, the dismissed victim, and now this… this anomaly. “If the ME’s preliminary report is correct, and the weapon was removed, how was the body left here without a trace of blood spatter beyond the immediate area? Unless…” She stood up, her eyes narrowing as she looked back at the chalk outline, then at the section of dislodged tiles. The compass. The energy readings. The Shade artisan. It all coalesced into a sickening, familiar pattern. “Unless it wasn’t a stab wound at all,” Harlow finished, her voice barely a whisper. She remembered the almost surgical precision, the lack of struggle. It wasn’t a blade that had killed the man. It was something that had *taken* something from him. Something that left no physical trace. “He was… excavated,” Eva said, her voice trembling slightly. “His essence. His vital force. Siphoned out through a temporary rift. The compass was likely a gift, or a payment. And when the energy flux stabilized… well, the rift closed. Or moved. Leaving only the husk.” Harlow felt a wave of cold wash over her, a familiar, icy dread that had nothing to do with the damp air of the Tube station. She knew that feeling. She’d felt it when DS Morris had vanished, leaving behind nothing but a strange, crystalline residue on the pavement and questions that had no answers, not in any textbook, not in any police manual. “And the Veil Market?” Harlow asked, turning to Eva, her expression a mask of grim understanding. “They deal in supernatural goods. Stolen artifacts. Banned substances. And information that can’t be found anywhere else. Including how to open these rifts. Someone wanted this runner silenced. Permanently. And they used the market’s services to do it.” She shone her flashlight beam onto the rough edges of the dislodged tiles, the dark void beyond. “This isn't just a crime scene, Kowalski. It’s a gateway. And whoever did this… they’re still out there. Probably with a very expensive, very dangerous trinket in their pocket.” Eva nodded, her hand hovering over the humming device. “And that compass will point the way. If we can find it. If we can read it.” Harlow’s gaze hardened. She pulled out her phone, her fingers flying across the screen. “I’ll have forensics re-examine the preliminary report. Tell them to look for residual energy, bio-signatures. Anything out of the ordinary. You,” she said, pinning Eva with a stern look, “you seem to know more about these… compasses than you’re letting on. I’ll need everything you’ve got.” Eva swallowed, her nervous habit kicking in as she tucked a stray curl behind her ear. “I can try, Detective. But this is dangerous territory. Not just for you, but for anyone who starts looking too hard.” Harlow allowed a grim smile to touch her lips. “Danger is my business, Kowalski. And I have a feeling this particular business has just gotten a whole lot more… interesting.” The Veil Market. A ghost of a place, a phantom of a trade. And now, a crime scene. The pieces were finally starting to lock into place, forming a picture far more terrifying than she had initially imagined. And she knew, with a certainty that chilled her to the bone, that this was only the beginning.
