Blackstone the Magic Detective was an old time radio show that was on the air from 1948 through to 1949. The show was based on Harry Blackstone, who was a magician in real-life. The show revolved around characters name John, Rhoda and of course, Blackstone. The show always starts out with John finding something from Blackstone’s studio, for example, a chainsaw, which then gets Blackstone and Rhoda retelling an adventurous story to John and how magic helped to save them. At the end of the show, a special magic trick is taught to the audience.
