In this post, "This is Your FBI", originally broadcast August 10, 1945 on ABC. In this case, we're hearing by way of "Mystery Playhouse" a "catch-all" anthology mystery and detective series broadcast by the Armed Forces Radio Service.
This episode, "Robert Peary, Impersonator" is a story about your FBI tracking down a con artist and his mother. The con artist, by the way, poses as a chicken inspector, proving that no crime is too strange to draw attention from federal investigators.
The show was transferred from an original AFRS transcription; it unfortunately has some groove wear in the opening moments of the program.
