THE MYSTERIOUS TRAVELER: THE MAN THE INSECTS HATED

The Mysterious Traveler was an anthology series on the Mutual Network from December 5, 1943 to September 16, 1953.  A mixture of mystery, suspense, science fiction and horror, the show was narrated by the titular character, played by Maurice Tarplin.  Created and written by Robert Arthur and David Kogan, the show produced almost 400 episodes.  Sadly, only about 75 episodes survive.  The show did spawn a magazine and a one-shot comic book, as well as two similar shows, The Sealed Book and The Strange Dr. Weird.

With the lonely whistle of a train in the background, The Mysterious Traveler would begin his weekly introduction:  "This is The Mysterious Traveler, inviting you to join me on another journey into the strange and terrifying.  I hope you will enjoy the trip, that it will thrill you a little and chill you a little.  So settle back, get a good grip on your nerves and be comfortable -- if you can!"

The episode linked below first aired on October 7, 1944.  In a crumbling mansion deep in a Louisiana bayou, Professor John Hanson has perfect Formula 397 -- a powerful insecticide.  Unfortunately for the professor, the insects are not happy about his success.

Enjoy.
