Mr. & Mrs. North made the transition from radio to television in 1952, but lasted just 1 season. In some respects, the series was a precursor to Robert Wagner's late 70's-early 80's series with a similar theme, Hart To Hart, or, given that Jerry North (Richard Denning, ex-My Favorite Husband) was a publisher, perhaps also Angela Lansbury's Murder, She Wrote. Think of it, then, as Murder, He Wrote.
Denning & Barbara Britton had taken over the roles of Jerry & Pam North on radio, making the transition that much smoother. Sad to say, viewers didn't seem to agree, hence the quick cancellation. NBC picked up rerun rights in 1954, again for 1 season.
Pizza Flix brings the episode, "Target", complete with commercials. Here, Jerry is targeted by an assassin who doesn't realize it's a case of mistaken identity.
