Paladin (Richard Boone) is hired by a mortally woman named Mrs. Kilmer (Lillian Bronson), who wants to learn the whereabouts of her long-long son before she dies. The trail of clues leads Paladin to Harper City, a town held in the grip of the wealthy--and psychotic--Fred Harper (Charles Aidman). Clearly, Harper knows something about Mrs. Kilmer's prodigal son, but he isn't telling...and Paladin is fully aware that the previous detective hired to locate the boy turned up dead. This is the final episode of Have Gun, Will Travel's third season. ~ Hal Erickson, Rovi
