A "False Flag" is the most complex and dangerous of intelligence operations—it is the recruitment of an agent who believes he is working for an entirely different country. Raised in Switzerland and fluent in German, Zeev Avni's specialty in Mossad was to cultivate former Nazis employed as military advisers to rebuild Egypt's army. None would willingly have cooperated with him if they had suspected for one moment that he was a Jew and a professional Israeli intelligence officer. Nor would Mossad have promoted him if they had known that their star performer was a long-term mole who for years had hemorrhaged secrets to the Soviets. When Avni's triple life was eventually exposed, he was tried in secret and sentenced to 14 years of imprisonment. Now, for the first time, he tells the story Mossad would prefer to forget. His engrossing story of commitment, duplicity, and betrayal is the only documented case of Mossad's penetration by Soviets, and it will be regarded as a classic by aficionados of espionage.
