I Love a Mystery is an American radio drama series that aired from 1939 to 1944, featuring three friends who ran a detective agency and traveled the world in search of adventure. Created by Carlton E. Morse, the series starred characters Jack Packard, Doc Long, and Reggie York, all played by various actors over the years, including Tony Randall as Reggie. The show's plots ranged from mystery and adventure to supernatural horror, often taking the characters to exotic locations. The series aired on NBC and the Blue Network, as well as CBS and the Mutual Broadcasting System with various sponsorships. I Love a Mystery saw revivals in 1948 under the title I Love Adventure, and later on Mutual from 1949 to 1952.
