Magnum, P.I. (1980): Season 2, Episode 7

2 - 7: Tropical Madness

Magnum is surprised when a beautiful English woman spurns his advances - much to the amusement of T.C. and Rick - instead preferring Higgins. Magnum is certain that the woman is feigning interest in Higgins only to somehow use him and plans to uncover the truth, but Higgins sees his doubts as sheer jealousy, and the ever volatile relationship between the two is pushed towards breaking point.
