Moonlight danced across crimson footprints. Rain drummed on wooden floors. Detective Hart felt icy dread. Shadows concealed a lifeless body. Leather gloves lay on floor. A broken locket gleamed faintly. Echoes hinted at hidden secrets. Someone watched from distant corridor. Night’s silence waited ominously close. Every heartbeat whispered impending danger.
