The rain fell hard against the old mansion’s windows. Detective Cole stepped inside, his coat dripping onto the floor. A single candle flickered in the dimly lit hallway. The butler stood frozen, his face pale with unspoken dread. "She’s dead," he whispered, pointing toward the study door. Blood pooled beneath the body, staining the Persian rug. A shattered glass lay near her outstretched, lifeless fingers. No signs of forced entry—only silence filled the room. The victim’s eyes stared blankly at the ceiling above. Cole knelt down, searching for clues in the shadows.
