Buddy Ebsen starred as Barnaby Jones, a retired private investigator who returns to the business after his son is murdered. The series ran on CBS from January 1973 (a mid-season replacement) to April 1980 and consisted of 178 episodes over 8 seasons.
Lee Meriwether played Barnaby's daughter-in-law and assistant, Betty Jones. Later in the series, Mark Shera joined the cast as Jedediah Romano (J. R.) Jones, Barnaby's (much younger) cousin.
Early episodes of the series featured William Conrad as Frank Cannon (who had his own series, Cannon). The premiere of Barnaby Jones was originally intended as a 2-part episode of Cannon but when a mid-season replacement series was urgently needed, it was spun off into a separate series.
