The rain drummed against the cobblestones as Detective Harlan stepped into the dimly lit alleyway. A single streetlamp flickered, casting long shadows that danced like restless spirits on the wet pavement. The body lay sprawled near the dumpster, limbs twisted in an unnatural pose that spoke of violence. Blood pooled beneath the victim’s head, dark and glistening under the feeble glow of the lamp. Harlan knelt, his gloved fingers brushing the cold skin, searching for any clue to the killer’s identity. A discarded cigarette butt lay nearby, its filter stained with a faint trace of lipstick. The detective’s eyes narrowed as he noticed the victim’s watch had been stopped at precisely 11:47. Footprints led away from the scene, deep and uneven, suggesting the killer had fled in a hurry. A distant siren wailed, growing louder as Harlan stood, his mind already piecing together the puzzle. The alley smelled of damp earth and something metallic, the scent of death lingering in the air. Harlan’s radio crackled to life, dispatch reporting another body had been found just three blocks away. The detective exhaled slowly, knowing this night would be far from over. Shadows stretched like fingers across the walls, whispering secrets only the dead could tell. Harlan adjusted his coat, stepping back into the rain, ready to chase the truth.
