The air in the abandoned Camden Tube station was cold enough to bite. Detective Harlow Quinn’s breath fogged in the beam of her torch, the light carving a tunnel through the oppressive dark. The scene was at the very end of the disused platform, past faded ‘Mind the Gap’ warnings and layers of grime. Two uniformed officers stood by a cordon tape that looked ridiculous in the vast emptiness. The body lay face down, a dark shape against the cracked concrete. Her colleague, DS Amir Chen, knelt beside it, the LED panel on his camera casting a sterile, blue-white glow. He glanced up as her footsteps echoed. “Quinn. Took your time.” “The briefing said ‘unusual location.’ They undersold it.” Quinn pulled on latex gloves, the snap loud in the quiet. She took in the scene. Male, late twenties, dressed in expensive but practical dark clothing—technical trousers, a merino wool jumper. No obvious signs of a struggle on his person. A small, expensive-looking backpack lay a few feet away, unopened. “What’s the story?” “Security guard doing his rounds above heard a shout, came down to check. Found him. No ID, wallet’s missing. Looks like a mugging gone wrong. Probably chased him down here, took his stuff, gave him a shove.” Amir pointed with his pen towards the edge of the platform. “Cracked his skull on the rail. Classic.” Quinn didn’t answer. Her eyes tracked from the body to the backpack. It was too neat. She moved past Amir, her torch beam sweeping the ground. The dust was thick, a pale grey blanket undisturbed for years, save for two clear sets of footprints leading from the service stairs to this spot. One set, the victim’s, by the tread. The other, heavier, booted—likely the assailant. They converged here. But there was no third set. No prints leading away. “Amir,” she said, her voice flat. “The assailant’s prints. Show me where they go after this.” He stood, brushing dust from his trousers, and shone his own light. The boot prints came in, stopped by the body. And ended. “He must have… jumped down onto the tracks? Walked along the rail?” Quinn was already moving, her light scanning the tracks. The rail was a foot below the platform edge, a narrow strip of filthy ballast and litter on either side. Not a single scuff in the thick grime on the rail itself. No disturbance in the dust and debris between the tracks for twenty yards in either direction. It was a perfect, undisturbed archaeological layer of urban decay. “He didn’t leave that way,” she said. “So he backtracked in his own prints. Careful-like.” “Possible.” Quinn’s tone said it wasn’t. She returned to the body, crouching opposite Amir. The back of the victim’s head was a mess of blood and hair, congealed black in the cold air. The injury was consistent with a fall onto the rounded iron rail. But something nagged. She leaned closer, ignoring the coppery smell. “Help me roll him.” Together, they eased the body onto its back. The man’s face was pale, eyes open and clouded. Quinn’s torchlight caught something. She tilted his head gently. Just below the hairline, near the temple, was a small, perfect circle of burned flesh, no bigger than a pencil eraser. The skin around it was blistered. There was no soot, no powder burn. It was a clean, cauterized wound. “What the hell is that?” Amir leaned in. “Entry wound? Too small. No bullet I’ve ever seen.” “It’s not a bullet.” Quinn’s mind raced, a cold feeling settling in her gut that had nothing to do with the station’s chill. She’d seen marks like that before. Once. On the rain-slicked pavement where DS Morris had died. The official report called it an ‘electrical anomaly.’ She’d never believed it. Her light swept over the victim’s hands. They were clean, no defensive wounds. But his right hand was clenched in a fist. Using her pen, she pried the stiff fingers open. In his palm lay a small, hexagonal token, carved from what looked like yellowed bone. It was etched with a complex, interlocking pattern that seemed to swim in the torchlight if you stared too long. Amir whistled softly. “Weird. Occult stuff? Some kind of gang symbol?” Quinn didn’t answer. She bagged the token, her movements precise. Her gaze drifted past the cordon, into the deeper darkness of the tunnel mouth. The air there felt different—thicker, with a faint, ozone tang that made the hair on her arms stand up. Her worn leather watch felt heavy on her wrist. “This wasn’t a mugging,” she said, more to herself than to Amir. “Come on, Quinn. Guy with no ID, fancy gear, in a place he shouldn’t be? He had something someone wanted. They took it and pushed him. The burn… maybe from a taser? A modified one?” “A taser leaves probes. This is a puncture. And where’s the wallet? If this was a robbery, why leave the backpack? It’s a top-end mountaineering pack. Worth a few hundred quid empty.” She stood, walking over to the discarded bag. She opened the main flap. Inside, nestled in padded compartments, were items that made no sense for a mugger’s target or a casual urban explorer: several small vials of iridescent liquid stoppered with wax; a bundle of dried herbs tied with silver wire; a notebook filled with dense, handwritten script in a language she didn’t recognize; and, wrapped in velvet, a small brass compass. She lifted the compass out. It was cold, heavier than it should be. The casing was verdigris-stained brass, its face etched not with cardinal points, but with intricate, spiralling sigils. The needle didn’t point north. It quivered, then spun lazily before settling, pointing unwavering into the dark tunnel. Amir came to stand beside her. “A busted compass. More junk.” “It’s not busted.” Quinn’s voice was low. “It’s pointing at something.” “The tunnel? It’s a dead end. Network sealed it off forty years ago.” She ignored him, following the compass’s indication. She took a few steps towards the tunnel mouth, the beam of her torch swallowed by the blackness. The ozone smell grew stronger. The uniformed officers shifted uneasily. “Quinn, leave it. Forensics will do a sweep. It’s a mugging. A weird one, but a mugging. We write it up, wait for the ID to come through missing persons, and go from there.” The compass needle began to vibrate in her hand. A low hum, more felt than heard, throbbed in the air. In her mind’s eye, she saw Morris’s face, the confusion in his eyes just before he fell. The unexplained ‘anomaly.’ The case they’d been working on—small-time artifacts, odd burglaries—had been shut down too quickly. She looked from the compass to the bone token in the evidence bag, to the strange, clean burn on the victim’s temple. The pieces didn’t fit the picture of a random crime. They fit another picture, one she’d been refusing to develop for three years. “He wasn’t mugged,” Quinn said, turning back to Amir. Her face was a mask of military calm, but her brown eyes were hard. “He was intercepted. He was coming here to meet someone, or to go somewhere. He had the token for entry. The backpack is a kit. Specialized. The burn isn’t from a taser; it’s a kill shot. Something that leaves minimal evidence. The assailant didn’t follow him in and didn’t leave on foot.” Amir frowned. “So how did he get out? He flew?” Quinn’s gaze went back to the empty, print-less dust where the boot marks ended. “No. He didn’t come in through the stairs, either. Not really. And he didn’t leave the way we understand leaving.” She held up the bone token. “This is a key. And this,” she lifted the compass, its needle still fixed on the tunnel, “is telling us the door is that way.”
