Barnaby Jones is an American detective television series starring Buddy Ebsen as a formerly retired investigator and Lee Meriwether as his widowed daughter-in-law, who run a private detective firm in Los Angeles, California. The show was originally introduced as a midseason replacement on the CBS network and ran from 1973 to 1980. Halfway through the series' run, Mark Shera was added to the cast as a much younger cousin of Ebsen's character, who eventually joined the firm.
