Jeremy Travers was found dead in his bedroom on his 60th birthday. Inspector Granger questioned the other guests - Jeremy's wife Amanda, daughter Barbara, business partner Gordon Smith, and secretary Claudia Simeone. Each person claimed they did not hear anything suspicious. However, Claudia said she heard someone enter Jeremy's room at midnight, and believed it was Amanda. Gordon had also argued with Jeremy before dinner about marrying Barbara for her money. The inspector was trying to determine who had a motive to kill Jeremy.
