Written and directed by Robert Arthur and David Kogan, The Mysterious Traveler fired aired on the Mutual Broadcasting System on December 5th, 1943.
The lonely sound of a distant locomotive heralded the arrival of the sinister narrator (portrayed by Maurice Tarplin), who introduced himself each week.
Although mostly sustained and often discontinued and revived, The show was popular enough with Mutual listening audiences that it later spawned a comic book and a magazine.
