Magnum, P.I. (1980)

Magnum is hired by a Supreme Court nominee to find the woman he married forty years ago, in 1941, on the eve of the raid on Pearl Harbour. He was a young Navy Ensign, she was a prostitute, and after their marriage they subsequently became separated in the bombings, with the Judge presuming her dead - until recently, after he has started receiving blackmail threats relating to an incident forty years ago... Magnum's investigations into the case are helped by the fact that Higgins wants a favour, and is being overly nice and co-operative in return...
