Patric Knowles was a good actor who was in a lot of interesting movies, such as the 1941 The Wolf Man. By the late 1950s he was also doing television. Here he plays the wealthy British hunter who comes to America to kill buffalo. Knowles in this episode really hams it up as a British Lord type of guy who has no clue.
He has an expedition guide played by long-time character actor William Mims (who disappears in the last scenes). A personal French hunting guide played by Lou Krugman, who was also character actor with a long career.
But the most interesting person on this champagne safari is his sister, played by the incredibly beautiful Valerie French. Valerie had a very dangerous 1950s film-noir look. At this point in time, she had been in a few A movies with such actors as Glenn Ford, Lee J. Cobb. She was married to the brother of Jon Pertwee (Doctor Who), and later married Thayer David (the promoter in the first Rocky movie). Every look from Valerie was danger and heat!
So as every Paladin safari story goes, people are getting killed off. Everyone is blaming a small group of Indians who are just making money from the tourists. Paladin in the only one who can figure out the mystery, but can he save the British Lord from getting murdered?
