The Hawaiian-set detective program MAGNUM P.I. was a huge hit during the 1980s. Tom Selleck plays Thomas Magnum, a Vietnam vet who retires from the military and moves to the Pacific islands to start a private detective agency. His allies include a couple of army buddies who also live on the islands, and proper former British army officer Jonathan Higgins, caretaker of the mansion where Magnum stays and foil to Magnum's fun-loving ways. A deft combination of action and mystery coupled with Selleck's humorous and charismatic performances, MAGNUM P.I. remains one of television history's most entertaining detective shows.
