Amazing book on CIA's most valuable spy in Soviet and his betrayal by CIA's one of its own. The book is riveting and grips you from beginning to the end. Almost made me want to join CIA. lol. but I doubt and seriously wish we don't have a second cold war. That would be terrible for all involved. US owes a lot to Mr. Tolkachev, the Soviet spy whose material gave US air to air combat technology upper hand for decades.
Overall, I highly recommend book. No matter what genre you are fan of you are going to enjoy this one especially if it's on audio.
