Rain lashed against the window. Thunder echoed through the mansion. Detective Vance checked his watch. Midnight had just passed quietly. Lord Blackwood lay completely still. Crimson blood stained the carpet. A silver dagger gleamed brightly. It protruded from his chest. Nobody had heard a scream. Every single door remained locked. The killer was still inside. Vance knelt beside the corpse. He noticed a strange clue. Dead fingers clutched a note. The game had finally begun.
