The body lay perfectly still. Detective Harris arrived at dawn. Blood stained the wooden floor. A knife glinted close by. Rain pattered against the windows. Shadows danced across the room. The victim wore formal attire. His expression showed final terror. No witnesses had come forward. Only silence filled the house. The clock had stopped ticking. Family photos lined the mantel. One frame appeared recently disturbed. The detective removed his hat. He surveyed the grim scene. Something felt distinctly off here. The door showed no forcing. The victim knew his killer.
