Heavy rain hammered fiercely against the shattered Victorian library window. Detective Vance stared quietly at the bloody carpet below him. Arthur Pendelton was lying completely motionless near the roaring fireplace. A silver dagger protruded sharply from his upper left back. Blood pooled darkly across the expensive Persian rug beneath him. Lightning flashed suddenly beyond the dark trees in the distance. The grandfather clock ticked loudly within the deadly silent room. Someone had murdered the wealthy billionaire during his own party. Vance knelt slowly beside the fallen owner of the estate. He noticed a torn photograph clutched inside the frozen hand. A familiar female face smiled back at the grim detective. Footsteps echoed ominously down the long hallway behind the door. The killer was probably still hiding somewhere inside this mansion. Vance pulled his loaded weapon from his heavy leather holster. This thrilling game of cat and mouse had finally started.
