Working for Mossad, the Israeli intelligence service, was like “living constantly in two worlds”. These were Tzipi Livni’s words to describe her life as a twenty-two-year-old working undercover in a chic quarter of Paris in the early 1980s at the height of Israel’s war with Lebanon. Livni only lasted a few years in Mossad before she left in 1984, when she married and launched her dazzling career in politics. Livni suggests that one of the reasons she left Mossad was because of the isolating, solitary life it required her to lead. Even her closest family members were not allowed to know she was a spy. As a young girl growing up in this environment, it is not surprising that Livni might have a natural attraction to becoming a spy and that she would be used to living with family secrets that she could not know about.
