Thunder shook the ancient manor house while heavy rain battered against the tall stained glass windows facing the dark garden. Detective Miller pushed open the heavy oak doors and immediately noticed the lifeless body resting quietly on the expensive rug. Crimson blood pooled around the wealthy victim as a single silver candlestick lay abandoned near his perfectly manicured right hand. Shadows danced across the cold stone walls every time bright lightning flashed through the terrible storm outside the silent room. Miller knelt carefully beside the strange corpse and saw a small crumpled note stuffed hastily inside the torn jacket pocket. Unfolding the white paper with gloved fingers revealed three typed words warning everyone about another brutal killing happening by midnight. The grandfather clock suddenly struck eleven times loudly down the long hallway, leaving exactly one hour to catch the killer.
