Magnum, P.I. (1980)

Robin's friend and aspiring writer Betty comes to the estate for a quiet place to overcome her case of writer's block as she works on her mystery adventure novel. In short order, she convinces Higgins to hand over the keys to the Ferrari and to relocate Thomas to the main house while she works in the guest house, much to Thomas's extreme displeasure. After Thomas is forced by a lack of transportation to let her observe his investigation of a hit-and-run insurance case, she begins to churn out a story inspired by Thomas's case, featuring Thomas as dashing international investigator Sebastian Sabre, Higgins as his faithful servant Boris, T.C. as his pilot Winston, Rick as club owner Swift, and herself as Sabre's glamorous girlfriend Collette. Her wild imagination unwittingly breaks open Thomas's investigation and plunges them both into danger.
