This time Jessica (Angela Lansbury) travels to Quebec, there to attend the trial of an old friend who has been charged with murdering his wife and then torching his house. In order to prove her friend's innocence, Angela ends up agreeing to serve as a witness. . .for the prosecution. The lawyers in the case are played by Claire Trevor and Patrick McGoohan, the latter making an amusing courtroom reference to the astonishing number of Jessica's nieces and nephews who've been accused of murder in the past!
