 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".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.
