The air hit her first, a subterranean chill thick with the competing stinks of damp concrete, ozone, and rat poison. Beneath it all, another scent coiled—something cloying and sweet, like overripe fruit left to rot in a cellar. Detective Harlow Quinn descended the last of the spiral stairs, her rubber-soled shoes making no sound on the cast-iron treads. The generator-powered floodlights hummed, casting the abandoned Tube platform in a harsh, sterile glare that failed to banish the oppressive gloom clinging to the vaulted ceiling. Police tape, incongruously bright, stretched between two tiled pillars. Beyond it, the forensics team moved in their paper-white suits, a stark contrast to the century of grime coating every surface. DC Phillips saw her and broke away from the huddle, his face pale and pinched under the lights. “Ma’am.” He gestured with his chin toward the far end of the platform. “Got here as fast as we could. Not a place you want to linger.” “Report,” Quinn said, her gaze already sweeping the scene, cataloguing details. The graffiti here wasn't the usual spray-painted tags. These were intricate symbols, daubed in what looked like ochre and charcoal, stark and geometric against the faded posters advertising pre-war musicals. “Victim’s a John Doe. Early twenties, maybe. No wallet, no phone, no ID. A commuter found the station access hatch open on his way home, got curious. Lucky he didn’t touch anything.” Phillips flipped open his notebook. “Single stab wound, center mass. Looks like a robbery gone wrong. Kid wanders into the wrong place, someone strong-arms him for his valuables, things get heated.” Quinn walked the edge of the tape, her eyes missing nothing. The dust on the platform was thick, undisturbed except for the tracks of the first responders and the forensics team. There were no scuff marks. No signs of a struggle, of frantic shuffling feet or a body being dragged. Nothing to support Phillips’s tidy theory. She stopped, crouching on her haunches. “Weapon?” “Not recovered. ME’s preliminary says it was something thin and sharp. Not a standard kitchen knife. Forensics are still looking.” Quinn’s gaze drifted to the body. He lay on his back near the tracks, one arm flung out as if in supplication. His clothes were odd—a tweed jacket too heavy for the season, worn but well-made, and trousers of a dark, rough-spun wool. He looked like he’d stepped out of a history book. There was a surprising lack of blood. The wound in his chest was a neat, dark pucker in his white shirt, the fabric around it barely stained. Precise. Surgical, even. “He doesn’t have defensive wounds,” Quinn observed, her voice flat. Phillips followed her gaze. “Maybe he was taken by surprise.” “In a face-to-face robbery? A young man, fit by the look of him? His first instinct would be to raise his hands, to shield himself.” She pushed herself to her feet, the movement economical, disciplined. Her worn leather watch felt heavy on her wrist. Three years. Three years since she’d stood in another strange place, looking at another body that made no sense, with Morris lying only a few feet away. She pushed the thought down. It had no place here. She nodded to the forensics officer documenting the body. “Anything in his pockets?” The officer, a young woman with tired eyes, looked up. “Nothing, ma’am. Turned them all out. Empty as a politician’s promise.” Quinn moved closer, the cloying, sweet smell intensifying near the corpse. It wasn’t decay. It was something else. Something alien. She looked at the victim’s face. His eyes were open, fixed on the grimy ceiling, his expression not of fear or pain, but of profound surprise. His right hand was clenched into a tight fist at his side. “What about his hand?” Quinn asked. Phillips craned his neck. “I saw that. Probably grabbed a handful of grit from the platform when he fell.” “There’s no grit on his knuckles,” Quinn said, her voice sharp enough to cut. She crouched again, careful not to disturb the scene. “Bag it. Let’s see what he was holding onto so tightly.” The forensics officer produced a pair of tweezers and an evidence bag. With delicate precision, she worked at the victim’s stiff fingers. There was a faint metallic clink as they sprang open. Something small and dark tumbled from his palm. It wasn’t grit. It was a compass. Phillips stepped forward. “Well, I’ll be. An old brass compass. Camden Market tat, probably.” Quinn said nothing. She watched the officer carefully tweeze the object into the bag. It was small, fitting in a person’s palm, the brass casing tarnished with a patina of green verdigris. As it turned under the light, Quinn saw the face wasn’t marked with the cardinal points of North, South, East, and West. It was etched with a series of interlocking sigils, symbols that mirrored the strange graffiti on the station walls. The needle, a sliver of dark, polished metal, wasn’t pointing north. It was spinning, a frantic, silent pirouette. A cold dread, familiar and unwelcome, settled deep in her gut. She’d seen an object like this once before, pulled from the wreckage of a case the Met had officially ruled an “unexplained gas explosion.” The case that had taken Morris from her. “This isn’t tat, Phillips,” she said softly, standing up. The hum of the generator seemed to deepen, the air growing heavier. “Ma’am?” “A robber stabs a man for his wallet and phone but leaves behind a potentially valuable antique?” She gestured around the platform. “This place… it’s a market.” Phillips frowned. “A market? Down here? It’s been abandoned since the fifties.” “Not that kind of market.” Quinn’s mind was racing, connecting the discordant pieces. The strange location, a place that wasn’t on any official map. The victim dressed in antiquated clothes. The surgical wound without a struggle. The sigils on the walls. And now this… this compass. “He wasn’t robbed. He was a customer.” “A customer for what? There’s nothing here but rats and ghosts.” Quinn ignored the jibe. She took the evidence bag from the forensics officer, holding it carefully. Inside, the compass needle continued its wild, silent dance. It wasn’t responding to the Earth’s magnetic field. It was responding to something else. Something nearby. She began to walk, slowly, holding the bag out like a divining rod. “Ma’am, what are you doing?” Phillips asked, his voice a mixture of confusion and concern. Quinn didn’t answer. She walked past the body, her eyes locked on the spinning needle. She followed an invisible line toward the tunnel entrance at the far end of the platform. The sweet, rotting scent grew stronger. The needle’s spin slowed, becoming more erratic, twitching left and right. Then, halfway between the body and the tunnel, it stopped. The needle locked into place, pointing directly at the tiled wall to her left. Quinn stopped, standing before a blank stretch of grimy cream and green tiles. There was nothing there. No door. No opening. She held the bagged compass closer to the wall. The needle quivered but held its position, resolute. “It’s pointing at the wall,” Phillips said, stating the obvious. “It’s broken. I told you, just junk.” “It’s not broken.” Quinn’s voice was low, certain. She reached out with her free hand, pressing her palm flat against the cold, grimy tiles. The wall felt solid, unyielding. But there was something else. A faint, almost imperceptible vibration humming through the ceramic, and a distinct drop in temperature that had nothing to do with the subterranean chill. It felt like standing before an open freezer. She knew this feeling. The air thinning, reality stretching like worn elastic. “The victim wasn’t running from his killer,” she said, her thoughts crystallizing into a terrible clarity. “He was coming here. He was following the compass.” She looked back at the body, then at the path she’d walked. The killer hadn’t ambushed him. They had waited for him. “They waited for him to find what he was looking for, and then they killed him. They didn’t want his wallet. They wanted to stop him from crossing over.” Phillips just stared at her, then at the wall, his expression blank. “Crossing over to where, ma’am? It’s a wall.” Quinn ran her fingers along the grout lines, feeling the hum intensify slightly under her touch. The evidence here didn’t add up because it wasn’t all here. The motive, the weapon, the killer—they weren’t from this side of the wall. This wasn’t a robbery. It was a border dispute. “Get a forensics surveyor down here,” she ordered, her eyes never leaving the tiles. “I want this section of wall analyzed. Thermal, sonar, the works. Find me a seam.” “A seam?” Quinn finally turned to face him, her sharp jaw set, her brown eyes hard. “This man died for something, Phillips. I intend to find out what’s on the other side of this wall that’s worth killing for.”
