Synopsis: Using a threat to Steve's life to ensnare Wonder Woman, Nazi agent Fausta Grables discovers that Diana Prince is Wonder Woman. Grables subsequently steals into Diana's apartment and finds the Wonder Woman outfit. She then begins to masquerade as Wonder Woman. Fausta's first order of business is to hold a public competition in which she challenges other women to physically best her. Diana, no doubt eager to control the potential public relations damage done to her Wonder Woman identity by a Nazi, finds another masked outfit to wear and then answers Fausta's open call to a public wrestling match. Victory will prove to an onlooking public which of the two is actually Wonder Woman. Unfortuantely, Fausta is able to tie up Wonder Woman with the golden lasso, stripping Diana of all her powers. Steve and Etta, having been previously alerted to the "switcheroo" are able to arrive in the nick of time to save the real Wonder Woman and right Fausta's wrongs.
Notes: This story forms the basis for the TV episode, "Fausta, the Nazi Wonder Woman". Curiously, though, one of the key points of the story was ignored by the Lynda Carter run. Wonder Woman's powers are explicitly shown in this story to reside in the person, not the costume. To quote from Diana, "You stole my costume--did you think it would give you strength?"By contrast, the TV show (at least in its first season) goes out of its way to show that the "girdle" is what allows Wonder Woman to use her Amazonian gifts outside Paradise Island. In a few episodes, Wonder Woman is shown to be rendered powerless by just pulling her girdle off. Why the writers decided to do that, when they clearly had knowledge of a story that explicitly states otherwise, is a real mystery.
