In 1943, a little-known author named Frederick Collins wrote a best-selling book called The FBI in Peace and War.
A year later, CBS radio turned the book into a weekly series starring Martin Blaine as FBI field agent Sheppard.
The program remained one of the best-rated crime shows on radio until it went off the air near the end of the old-time radio era, in 1958.
This episode, Unfinished Business, aired on August 2, 1951.
