The heavy rain battered the old mansion windows while a bitter cold wind howled through the dark and empty halls. Detective Miller stared at the lifeless body lying on the very expensive Persian rug near the grand old stone fireplace. A sharp silver dagger was buried deep inside the chest of the wealthy victim who owned this very vast estate. He carefully pulled out his small leather notebook to write down the exact time of his sudden and grim arrival. Three nervous suspects waited quietly in the dim library while the tall wooden grandfather clock ticked loudly in the background. The clever detective knew that one of these seemingly innocent people had committed this terrible and truly unforgivable murderous crime.
