Herbert Marshall travels the globe as the dashing and debonair Man Called X. Dispatched on international adventures, the Man Called X is really secret agent Ken Thurston, enemy to spies, saboteurs, and insurgents wherever they may lurk. Marshall gave radio a suave super spy in one of the best espionage programs of the era. We'll hear Ken Thurston in "Japanese Underground" (originally aired on NBC on January 20, 1951) and "A Ton of Dynamite" (originally aired on NBC on February 26, 1952).
