Where is Helen Eustis if she's still alive? If not, when did she die, did she leave any family?
As of this year Helen Eustis will turn 93 years old. She was born in Cincinnati, Ohio in 1916. She was married twice and had one son. She was famous for "The Horizontal Man" and she was an editor and translator of books. As far as where she is now, there is no information that I could find on-line as to where she is at this point in time. In her day she was responsible for adding a new realism to the mystery genre and was adept at the psychological side of the antagonist. Thanks for your question. I have included a link where you can read what information I could find.
