The storm raged outside the mansion on that fateful night. Lightning cracked across the dark and brooding Tennessee night sky. Inside, six guests gathered around the massive mahogany dining table. The host poured wine while thunder shook the oak doors. Everyone laughed nervously as the lights suddenly went completely black. A scream pierced the darkness from the upstairs library room. They found Lord Blackwood slumped over his antique writing desk. Blood pooled beneath the chair onto the Persian wool carpet. The knife lay glinting in the candlelight near his hand. Inspector Gray arrived exactly at midnight with his leather notebook.
