Oreste Pinto was a Dutch Intelligence Officer whom General Eisenhower called "the greatest living expert in security." The radio program, Spy Catcher, was based on Pinto's work in the Allied Counterintelligence Service. Each episode has Pinto interrogating a political refugee or seeming Allied Serviceman. Using all the psychological and verbal tricks at his command, Pinto tries to prove that the subject is a Nazi Spy.

Spy Catcher was penned by Robert Barr, and starred Bernard Archard as Pinto. Barr went on to write 26 episodes for Radio, with Archard continuing his role.
