Hank Patterson does a great job as Pappy French. He and Dick Boone have the beginning of a buddy movie, except for French being adamantly bad and Paladin being unalterably good where stolen money is concerned.
The Have Gun Will Travel series gave Hank Patterson a scope he rarely got in any other venue. Considering he ended his acting days on Pettycoat Junction doing a cut-out comic figure, the range of his skills would have been hard to know about without HGWT. It was a pleasure to see French and Paladin develop a cautious friendship in this story of the last days of a bad man. Paladin's feelings for French are graphically displayed when he pours lead into the man who kills him. I believe this is the only time we see Paladin kill an adversary while in a towering rage.
