''Oliver's Travels'' is a five episode British miniseries adapted by Creator/AlanPlater from his own novel and starring Alan Bates and Sinéad Cusack.
Oliver, a professor of comparative religion with a penchant for word games, is fired from his job and decides to take a road trip to the home of his favorite crossword compiler who uses the pseudonym Aristotle. When he finds the house abandoned, he alerts the police and eventually secures the assistance of a police investigator, Diane Priest. She discovers that Aristotle is now living in the Orkneys, as well as suggestions of high level corruption.
Oliver proposes marriage to Priest because when she is telling him how to address her, she says, "Diane, not Priest" which is an anagram for "predestination." She refuses, but they travel together to the Orkneys, he investigating the disappearance of Aristotle, and she investigating the coverup she begins to reveal. Gradually, connections appear linking the two incidents into one vast conspiracy, and things begin to get out of hand.
