The rain fell hard upon the old dark house. A single light burned bright within the study room. Inside, a man lay still upon the cold floor. His eyes were wide with fear and sudden shock. No sound escaped his lips as life faded fast. The clock struck twelve with loud and heavy chimes. Someone walked away from where the body lay. Footsteps faded quick into the stormy night air. Now silence fills the hall where death has arrived. The mystery starts right here in this very moment.
