Rain slicked the tiled platform of the disused Camden Underground station. Detective Harlow Quinn stepped beneath the vaulted brick archway, ducking under yellow police tape. Water dripped rhythmically onto the rails below. Her worn leather watch ticked against her wrist. Salt-and-pepper hair plastered to her skull. A sharp jaw tightened. Footsteps echoed off the curved walls. "Uniforms secured the perimeter above," Sergeant Vance muttered, holding a flashlight beam steady against the damp masonry. "Locked iron gates on the street level. No forced entry. No way down unless someone dropped through the ventilation shafts." Harlow scanned the platform. Scorch marks scarred the vintage railway tiles in a jagged circle. A faint smell of ozone hung in the air, biting the back of her throat. "Look at the soot dispersion, Vance," Harlow pointed a gloved finger toward the center of the platform. "An ordinary incendiary device leaves a directional spray. This pattern radiates in a perfect sphere. The heat originated from nowhere and everywhere simultaneously." Vance stepped closer, his boots crunching on glass. "Gas leak. Pocket of methane pooled down here. A stray spark from a vagrant's lighter blew the center out." "Methane doesn't leave sulfur residue on the third rail." Harlow knelt beside the rusted steel track. White crystalline dust coated the iron. She scraped a small amount onto a black plastic evidence card. "And vagrants don't trade in alchemical salts. This smells like the black market stalls we cleared out near Holborn last month." "You chase shadows, Quinn," Vance sighed, shining his light across the tracks toward a dark tunnel mouth. "Forensics already combed the perimeter. They found the victim's wallet thirty feet inside the tunnel. Standard robbery-homicide. Mugger pushed the poor bastard onto the tracks, electrical surge finished him." "Where is the body?" Harlow stood up, her joints popping in the subterranean chill. Vance shifted his weight, avoiding eye contact. "Paramedics transported the remains to St. Jude's ten minutes before you arrived." "Before I arrived on scene." Harlow crossed her arms, narrowing her brown eyes at her colleague. "Jurisdiction dictates homicide detectives receive immediate dispatch. Dispatch logged this call forty minutes after the tube maintenance crew reported the flash." "Radio dead zones down here," Vance offered, his voice tight. "You know how the signal drops beneath the Northern Line." Harlow ignored the excuse. She walked the length of the platform, eyes sweeping over the vintage advertising posters peeling from the curved walls. One poster advertised theatrical productions from nineteen-ninety-four. The paper remained pristine, untouched by decades of underground dampness. "Maintenance crews didn't report this," Harlow said, her boots clicking rhythmically against the stone. "Look at the dust on the platform edge. Footprints intersect the scorch marks. Boots with tread patterns matching Metropolitan Police-issue footwear." Vance swallowed hard. The beam of his flashlight trembled slightly against the brickwork. "Officers secure the scene. They walk around the blast radius." "They walked across the center." Harlow crouched again, inspecting the disturbed dust. "Two sets of boots stood inside the circle while the chemical residue was still smoking. They weren't securing the area. They were staging it." "You need to let this go," Vance stepped into her line of sight, blocking her view of the tunnel. "Command wants this closed by morning. Accidental death. Faulty third rail. End of file." "Morris died on a scene just like this," Harlow murmured, her gaze locking onto Vance's face. "No forced entry. Clean angles. Impossible physics. And internal affairs burying the report before the ink dried." "That case closed three years ago," Vance snapped, his voice echoing off the curved ceiling. "Keep chasing phantoms and you will lose your shield." Harlow reached into her trench coat pocket, wrapping her fingers around a small brass compass with a verdigris patina. The needle inside spun wildly, ignoring magnetic north, locked onto the dark tunnel mouth where the victim's wallet supposedly lay. "The wallet wasn't dropped," Harlow said, stepping past Vance into the shadows of the tunnel. "It was left as a beacon."
