The rain drummed against the cobblestones as Detective Harlan adjusted his coat, his breath fogging in the cold. A single streetlamp flickered, casting long shadows that danced like restless ghosts across the alleyway’s damp pavement. The body lay sprawled near the dumpster, limbs twisted unnaturally, the victim’s face frozen in a silent scream of terror. Blood pooled beneath the corpse, dark and viscous, its metallic scent mingling with the damp earth and decay. Harlan knelt, his gloved fingers brushing the victim’s wrist, already cold to the touch, life long since fled. A discarded cigarette butt smoldered nearby, its smoke curling into the night like a ghostly accusation waiting to be heard. The detective’s eyes narrowed as he spotted a single, gleaming button near the body, out of place and untouched by the rain. Footsteps echoed in the distance, growing louder, and Harlan knew the first witnesses—or perhaps the killer—were approaching fast. His hand rested on his revolver, fingers tightening as he prepared to face whatever horror the night had in store.
