I believe that was "Treason". I have it but still haven't read all of it - but she does set the record straight on McCarthy - excellent book.
Thank you, she is a prolific writer, and I wasn't sure which one it was. I gave all of my books to a dem friend to try to convince her that Ann is a talented writer, not just the "daughter of Satan" as she is known to her and her dem friends.
You are correct. "Treason" explores the findings of the Venona Project, which showed that McCarthy was on the right track.
