S5, Ep 10: Luther Gillis File
#001. Magnum finds himself the flavour of the month when Higgins asks him to look into who is blackmailing him. Unfortunately for him, Robin Masters has asked Magnum to track down an embezzler working in a local bank. However, he gives Higgins the number of a man to take the case on for him - private eye Luther Gillis!
Starring Tom Selleck, John Hillerman, Roger E Mosley, Larry Manetti, Eugene Roche, Don Knight, Gary Grubbs, Kwan Hi Lim, Gary Pagett, Gary Spotts, Peggy Anne Siegmund, David Johnson, plus the voice of Orson Welles as Robin Masters in one of his last vocal appearances before he died the following year. Having dispensed with one irritant in the new "Mac", sadly the series gets lumbered with another when Magnum - assigned a case by Robin Masters - proves too busy to help Higgins, who is being blackmailed and instead tells him to hire Luther Gillis, old fashioned private eye. Magnum - how could you?
