The old mansion stood silent on the stormy hill outside. Rain lashed against the tall windows of the dark house. Inspector Miller arrived alone at the rusted iron gate tonight. The body lay in the center of the dark library. Blood had dried upon the Persian rug beneath his head. A single red rose rested upon his cold white chest. The doctor knelt beside the victim without saying a word. Two glasses of wine sat on the mahogany side table. One glass remained completely full and untouched by human lips. The old clock on the mantelpiece had stopped at midnight. Silence filled the room like a thick heavy velvet blanket. Miller opened the heavy oak door to the dark study. Fresh footprints led from the body toward the hidden door. Red drops formed a trail marking the killer's escape path.
