Thunder shook the dark mansion. Detective Vance entered the study. Lord Blackwood lay dead inside. Crimson blood stained the rug. A heavy candlestick rested nearby. Every single window was locked. The fireplace held warm ashes. Someone burned a crucial document. Vance adjusted his leather gloves. Four wealthy guests waited downstairs. Each guest hated the victim. The killer was still here.
