Whether the role of lady spy Baroness Karin Geza in Top Secret was created for Ilona Massey, or if Miss Massey was created for the role is open for debate. There can be little argument that it was one of the most successful castings of early 50’s radio. Supposedly, the real-life inspiration for the Baroness Geza character was a “close friend” of Miss Massey’s who actually worked as a spy for the Allies during WWII and its aftermath. The scripts were adapted from stories the friend related to Massey.
Top Secret failed to gain sponsorship, and NBC was notorious for being unkind to sustained programs, especially when it came to scheduling. Listeners who may have wanted to follow the show would have found it difficult, because sustained programs were often bounced all over the weekly broadcast schedule.
In this second installment of Top Secret, the Allied spy masters intercept a transmission that the top Nazi Spy in New York Admiral Stroesser, has requested a female assistant with very specific height and weight requirements. Of course, it turns out that Baroness Geza meets the description, and she travels to New York in place of the German lady agent. Allied agents in New York know that Stroesser is readying his escape, and they would rather kill him than let him return to Germany with his secrets. The Baroness insists that it is too important to find out what those secrets are and takes her place as Stroesser’s assistant. She finds out that the reason for the particular size requirements are so that the Admiral can impersonate her after he is smuggled aboard a German liner in a coffin!
