Jessica (Angela Lansbury) takes a sentimental journey to the New Hampshire campus of her old alma mater. Alas, her favorite English professor Leon Walker (E.G. Marshall) is in no mood for a reunion: Discovered at the scene of a young girl's murder, Professor Walker has already confesses to the crime, claiming that he killed in self-defense. Jessica does not believe this confession any more than she believes the subsequent confession made by a young student with whom the dead woman had been involved. Among the guest stars this week is Dinah Shore, appearing as Jessica's onetime sorority sister Emily Dyers. ~ Hal Erickson, Rovi
