Starring Glen Langan as the lead character Barton Drake, Mystery Is My Hobby is a detective series that aired on Mutual Radio from 1947 to 1948. In the series, Drake was writer who loves to solve crimes and mysteries, together with his sidekick Noah Danton, a police officer. Before each episode ended, Drake would cite his line "mystery is my hobby," hence the title of the show. Murder Is My Hobby was actually the show's original title. However, since the sponsor didn’t find that title appropriate, it was changed.
