12/5/1943 The Mysterious Traveler sets out

December 5, 1943.  This date saw (uh, heard) the premiere of the radio show The Mysterious Traveler.  Robert Arthur, Jr. and David P. Kogan wrote the show, following the success of their Dark Destiny.

Each episode began with Maurice Tarplin announcing: "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 Mystery Writers of America gave the Mutual Broadcasting System's show an Edgar for best radio drama.
