An truly fascinating book regarding one of the biggest spy stories of the Cold War. It was disheartening to see how shamefully he was treated by the government after his defection to the United States. The story is gripping and keeps you at the edge of your seat. I could not put this book down. A must read for the fans of history and spy stories.

Thank you to #NetGalley for the ARC in exchange for my honest review.

Well written and very interesting portrait of a brilliant espionage agent who believed his own press and the western spy organizations he both provided incredible intel and embarrassed them with his abilities.
I requested and received a free temporary ebook copy from St. Martin's Press via NetGalley. Thank you.

Took a while to get into, this book is full of interesting characters from the Spy world. Names like George Blake, Kim Philby and James Jesus Angleton. I found it to be informative but sometimes filled with too much minutiae. Overall, if you enjoy reading about real spies, this book is better than average. I received an e-book from NetGalley in return for an unbiased review.

This book was very interesting and exciting. Kept my interest from start to finish. Would definitely recommend this to anyone.
