The rain fell hard against the old mansion windows. Detective Cole stepped inside, boots squelching on the marble floor. A single lamp flickered, casting long shadows across the room. The victim lay sprawled near the fireplace, blood pooling darkly. No one heard the gunshot over the storm’s relentless roar. A broken clock on the wall read exactly twelve-thirty sharp. The butler stood frozen, hands trembling at his sides. A half-empty glass of whiskey sat on the table. Footprints led away, muddy and barely visible in the dim light. Cole’s instincts screamed that nothing here was as it seemed.
