Blackstone - 1949 (ep35) The Knife From the Dark

We begin with episode 14 with this program. Blackstone, the Magic Detective was a 15-minute radio series based on Elmer Cecil Stoner's comic book series Blackstone, Master Magician. The program aired Sunday afternoons at 2:45pm on the Mutual Broadcasting System from October 3, 1948, until March 26, 1950.

Radio
Starring Edwin Jerome as "the world's greatest living magician," the radio series was based on real-life magician Harry Blackstone, Sr.

The series was announced by Don Hancock from October 1948 through June 1949, and Alan Kent from July 1949 through to the end of the series in March 1950. The background organ music was supplied by Bill Meeder. Scripts were mostly by Walter B. Gibson, the ghostwriter of Blackstone's books, and Nancy Webb, who worked with Gibson on Chick Carter, Boy Detective.

Characters and story
The show usually opened with Blackstone (Ed Jerome) and his assistant Rhoda Brent (Fran Carlon) talking with a friend of theirs, either Don Hancock or Alan Kent (played by the episodes' announcers in-character as themselves) or John (Ted Osborne). A past adventure of Blackstone's would come up in conversation, and that mystery story was then dramatized as a flashback.

After the mystery's climax, the narrative returned to the three main characters as Blackstone performed a magic trick. After a commercial break handled by the announcer, Blackstone returned to demonstrate and explain the trick so that listeners could perform it for the amusement of their friends.
