circle of German scientists who worked on the Egyptian armaments programs. Lotz was sent to Germany in 1959 in order to establish his cover story as a German businessman and ex-Wehrmacht officer who had served in North Africa, and was a former member of the Nazi Party. After purportedly living for 11 years in Australia where he had bred horses, in his "legend" (cover story) Lotz had come back to Egypt in order to establish a riding club. The North Africa element of his cover story was devised because Lotz, who had interrogated hundreds of the German POWs in World War II, was familiar with their way of life and could easily tell war stories about his "comrades." The riding club would allow Lotz to make contact with Egyptian high society. He arrived in Cairo in 1960 and began immediately to form friendships with high ranking Egyptian officials and military personnel. In Cairo, Lotz portrayed himself as a dedicated Nazi and anti-Semite so well that the rumor quickly started to spread that he was a former SS officer. Lotz traveled to Paris in June 1961 for a meeting with his operators (he was in the meantime transferred to the responsibility of the Mossad), where he received large amounts of money and a transponder for sending secret messages. Lotz visited his wife and son who were housed in Paris during the time of his mission in Egypt. During his train journey from Paris, Lotz met a German woman called Waltraud Neumann and decided to marry her, despite the fact he was married to another woman. Lotz married Neumann in Munich. Lotz did not discuss his intentions with his operators. Mossad was horrified by this and even considered recalling Lotz, but in the end allowed Lotz to continue his mission. His new wife was allowed to join him. While she soon discovered his real occupation, she was told Lotz worked for NATO and she began to help him. In Cairo, Lotz eventually opened his riding club and continued to befriend the elite of Egyptian society. He managed to persuade them to show him the Egyptian missile launch sites and he gathered intelligence on the Egyptian military and its industries. He also composed a list of German scientists who worked for the Egyptians and in September 1964 he sent letter bombs to some of them, in an attempt to induce them to cease
