Not a bad summary of several extensive and high-profile espionage cases handled by the Army. The focus and details are a little different from other books, so I definitely learned additional info from this book (and my study on the subject has been thorough). If you are interested in the Cold War, this is an excellent book to add to the reading list.
I wish there had been an index. Also the storytelling is more detailed and less immersive than I prefer, but that did enable the author to recount several cases in one relatable book.
