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 abandoned Tube station smelled of damp concrete and rust, the kind of scent that clung to the back of your throat like a bad memory. Detective Harlow Quinn stepped off the last rung of the maintenance ladder, her boots hitting the platform with a sharp *clack* that echoed down the empty tunnel. The beam of her torch cut through the gloom, illuminating peeling posters from the 1970s and the skeletal remains of turnstiles long since stripped for scrap. "Quinn, over here." She turned. Detective Sergeant Cole stood near the far wall, his hands shoved deep in the pockets of his overcoat, his breath fogging in the cold air. The station’s emergency lights cast his face in sickly yellow, deepening the shadows under his eyes. Quinn adjusted the worn leather watch on her left wrist, its strap creaking. "What’ve we got?" Cole jerked his chin toward the tracks. "Body. Male, late twenties. No ID. Looks like a junkie OD at first glance—track marks, foam around the mouth—but the ME’s already raising eyebrows." Quinn stepped closer, her torch sweeping over the scene. The victim lay sprawled on his back, one arm flung out as if reaching for something. His skin had an unnatural pallor, almost waxy under the harsh light. But it was the eyes that made her pause. Wide, staring, the irises ringed with a faint, shimmering blue—like oil on water. "Toxicology’s going to take a while," Cole said, "but I’m telling you, this isn’t just smack. Something’s off." Quinn crouched, her knees popping. She didn’t touch the body, just studied it. The victim’s fingers were curled into claws, the nails split and caked with dirt. Not the kind of grime you picked up on the streets. This was older. Deeper. She stood, brushing her hands on her trousers. "Where’s the rest of the team?" "On their way. I was first response." Cole hesitated. "You think this is connected to the other two?" Quinn’s jaw tightened. Three bodies in as many weeks, all young men, all found in abandoned or liminal spaces—an old warehouse, a derelict church, and now this. All with the same eerie blue ring in their eyes. All with no signs of struggle, no defensive wounds. Just… empty. She didn’t answer him. Instead, she turned her torch toward the wall behind the body. The beam caught something metallic, half-buried in the gravel beside the tracks. A small, brass compass, its casing dulled with verdigris. The needle wasn’t pointing north. Quinn picked it up, turning it over in her palm. The face was etched with strange symbols, spirals and jagged lines that made her eyes ache if she looked at them too long. The needle spun lazily, then settled, pointing toward the far end of the platform. Cole frowned. "What the hell is that?" "Don’t know." Quinn’s voice was tight. She slipped the compass into her coat pocket. "But I don’t like it." She moved down the platform, her torchlight flickering over the tiled walls. The station was a relic, its name—*Camden Road*—still visible beneath layers of grime and graffiti. But something was wrong with the graffiti. The tags were sharp, precise, almost… deliberate. Like they’d been painted with a purpose. Then she saw it. A symbol, spray-painted in what looked like blood, half-hidden behind a crumbling pillar. A circle, bisected by a jagged line, with smaller marks radiating outward like rays. It wasn’t a gang tag. It wasn’t anything she recognized. But she’d seen it before. Three years ago, in the case notes of her dead partner. Quinn’s breath hitched. DS Morris had been investigating a string of disappearances before he vanished. The files had been thin, redacted in places, but she remembered the symbols. The same damn symbols. Cole appeared at her shoulder. "Quinn? You okay?" She didn’t answer. Instead, she pulled out her phone, snapping a photo of the graffiti. The flash illuminated the platform for a split second, and in that moment, she saw something else. A shadow. Not a trick of the light. Not a smear of dirt. A *shadow*, clinging to the wall like spilled ink, too dark, too *wrong*. It rippled, just for a second, as if disturbed by the flash. Then it was gone. Quinn’s pulse hammered in her throat. She turned slowly, scanning the platform. Nothing. Just the body, the tracks, the empty air. Cole was watching her, his expression unreadable. "Quinn. Talk to me." She exhaled sharply. "We need to secure this scene. No one in or out until forensics is done. And I want a full sweep of the tunnels. Every inch." Cole’s eyebrows lifted. "You think there’s someone else down here?" Quinn’s fingers twitched toward the compass in her pocket. The needle was still spinning. "I think," she said carefully, "that this isn’t just a body. It’s a message." She turned away from him, her torchlight cutting through the dark. The compass was warm against her skin, almost pulsing. Like it was alive. And for the first time in three years, Harlow Quinn let herself consider the possibility that her partner hadn’t just died. He’d been taken.
