The rain hammered down hard, soaking the empty cobblestone street. A flickering streetlamp cast eerie shadows across the deserted corner. Detective Marlowe stepped cautiously, his coat collar turned high against cold. A distant scream echoed faintly, breaking the silence of night. Footsteps approached quickly, crunching over wet leaves with urgent rhythm. Marlowe found the body sprawled beneath the ancient oak tree. Blood pooled slowly, staining earth where the pale victim lay motionless. Nearby, a shattered locket glistened, reflecting the dim lamplight eerily. The detective knelt down, eyes sharp, searching clues with practiced skill. Thunder rumbled softly as the night’s dark mystery began unfolding.
