"The Mysterious Stranger" (February 17, 1959) features Adam West ("Batman") as Frederick Pulaski, a declared descendant of the Polish military commander Casimir Pulaski, who was mortally wounded at the British Capture of Savannah, Georgia, in the American Revolution. Casimir Pulaski, "the father of the American cavalry", however, never married or had direct descendants and died at the age of thirty-four. In the story line, Frederick Pulaski is a concert pianist who defends oppressed Polish miners in a western town. After studying law under the deceitful Jay Hollis (Frank Cady), who take a fatherly interest in Tom Brewster, Sugarfoot befriends Pulaski in a legal hearing and reconciles him with the young woman by whom both are smitten, Kathy O'Hara (Sue Randall of "Leave It to Beaver"), who is also studying to be a concert pianist. Karl Swenson appears in this episode as Kathy's wealthy Irish father, Dennis O'Hara, who had mistakenly placed his full confidence in lawyer Hollis. Walter Burke plays a bartender in this episode.
