The rain hammered relentlessly against the tall windows of Blackwood Manor as the guests gathered for their elegant dinner party. Lady Victoria Ashworth had carefully planned every single detail, from the sparkling crystal glasses to the freshly cut white roses. Nobody seated at the long dinner table noticed when the butler carried the last bottle down into the old cellar. At precisely nine o'clock, a piercing scream suddenly shattered the comfortable silence that had settled over the entire dining room. The young maid stood frozen in the doorway, her pale face as white as the freshly pressed linen tablecloth itself. She had just found the old master of the house lying motionless on the cold floor of his private study. Sir Edmund Ashworth stared upward with glassy, empty eyes, a silver letter opener buried deep in his broad, motionless chest. The storm outside grew even fiercer, as if the weather itself somehow understood that something truly terrible had happened tonight. Six guests sat around the long dinner table, and every single one of them now had reason to start lying. Detective Sarah Chen would arrive within the hour, but the killer was already preparing a very careful and convincing story.
