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 on the Persian rug beneath her lifeless body. Her diamond necklace lay shattered, scattered like broken glass shards. A half-empty glass of wine sat on the desk. The clock struck midnight, echoing through the silent house. No one dared breathe as the storm raged outside.
