Heavy rain battered the window. Thunder shook the dark mansion. Detective Vance entered the study. Blood stained the Persian rug. Lord Blackwood lay completely still. A silver knife pierced him. His dead eyes stared upward. Glass covered the oak floor. Someone shattered the patio door. Vance lit his brass pipe. Smoke drifted into cold air. The killer left no footprints. Only one clue remained behind. One red rose rested nearby. This murder was deeply personal. Vance checked his gold watch. Midnight brought a grim puzzle. Three suspects waited down below. Every suspect hated the victim. Now the real game begins.
