Rain tapped the tall windows while the old mansion slept. Inside the marble hall a grandfather clock counted silent minutes. Lord Ashworth's guests gathered near the fire with careful smiles. A butler poured sherry into glasses without meeting any eyes. At nine the study door opened slowly then clicked shut. No one saw Lord Ashworth leave the crowded drawing room. Minutes later a maid found his body beside the desk. The knife in his chest bore the bright family crest. Every guest stood frozen as lightning split the dark sky. Detective Hale arrived before police and studied every silent face.
