From Library Journal: The author writes of Johnny Walker, the flamboyant mastermind of one of the most damaging spy rings in U.S. history, "His only loyalty was to the elaborate game he was playing." Unlike John Barron's Breaking the Ring ( LJ 4/1/87), Blum's extensively documented account concentrates on the personalities involved. Most attention is devoted to Johnny, a former Navy warrant officer who sold top secret codes and technical manuals to the Soviets for 17 years before his ex-wife exposed the operation, which by that time included their son Mike, Johnny's brother Art, and a friend.
