Private eye Barnaby Jones works with his widowed daughter-in-law to solve cases.

Barnaby Jones was a former private eye who temporarily came out of retirement to track down the killer of his son Hal, who had taken over the family business. After bringing Hal's murderer to justice (with the assistance of fellow CBS gumshoe Frank Cannon), Jones decided retirement just wasn't his bag after all, and rehung his shingle with the assistance of daughter-in-law Betty, who ran the office and Barnaby's personal crime laboratory, and (later) young distant cousin Jedidiah, who did the cases' legwork.—Marty McKee <[email protected]>

Former private investigator Barnaby Jones comes out of retirement to find the person who killed his son Hal. With the aid of fellow P.I. Frank Cannon, Barnaby eventually finds his son's killers. Barnaby then decides to come out of retirement and resumes his practice with Hal's widow Betty serving as his secretary. A few years later, Barnaby's cousin Jedidiah (a.k.a. J.R.), a law student, seeks Barnaby's help in finding the killers of his father. Just like a few years earlier, the two find the men who killed J.R.'s father and as a result J.R. decides to stay on with Barnaby working as his legman while he is studying law. Their contact on the L.A.P.D. is Lt. John Biddle.—Brian Washington <[email protected]>
