## Description

"The Double-Cross System is the amazing true story of how British intelligence penetrated and practically operated Nazi German's spy network within the British Isles. With great imagination, care and precise coordination, the British were able to identify Nazi agents, induce many to defect, and supply Germany completely false information about bombings, battles, and even the D-Day invasion. Told by the man who himself masterminded the entire unbelievable four-and-a-half-year scheme, and filled with dazzling tidbits and extraordinary stories, The Double-Cross System is a testimony to Britain's skill in the fine art of counterespionage"--
