The silver knife sparkled beneath the bright and pale moon. Blood seeped slowly into the thick wool of the carpet. Arthur stood frozen while he stared at the lifeless body. He did not expect to find his brother dead today. The heavy front door creaked open with a sudden moan. Someone else was inside this house during the stormy night. Shadows danced across the walls like ghosts of the past. He gripped his flashlight tightly as his palms grew sweaty. A single gloved hand reached out from the dark hallway. The clock struck midnight as the final candle flickered out.
