Lillian Stanhope and Nicholas Frame are two famed actors in London, a venerated husband and wife team set to act in 'Macbeth.' Producer Sir Roger Haversham has been Lillian's lover but finds out he has been deceived by the couple and threatens to interrupt their engagement. Lillian kills him accidentally during an ensuing fight. Thereafter, the pair take the corpse to his mansion and stage his "accidental" death; however, Lt. Columbo (in London to learn about new investigation methods used by Scotland Yard) smells something fishy in this supposed accident. Written by
