The heavy velvet curtains muffled the sound of the falling rain against the tall windows of the dark manor house. Lord Harrington lay sprawled across the Persian rug with a silver letter opener protruding from the center of his vest. A single puddle of crimson blood slowly began to seep into the intricate blue patterns of the expensive wool carpet. Detective Miller pulled his damp collar up and stepped over the threshold into the room where the victim was cooling. No one had heard the struggle over the loud thunder that shook the stone walls of the isolated mountain estate. The butler gripped his trembling hands together while he watched the investigator examine the scene with a very sharp eye.
