“When she was twenty, my firm and the CIA were pursuing the members of a terrorist organization in Cairo who had been killing foreign tourists. We received a tip that half a dozen members of the group would be traveling in a white Renault van along a major boulevard, en route to planting some explosives. Cooperating with Egyptian intelligence, our people set up an elaborate trap for them at an intersection. There wasn’t supposed to be any traffic to speak of. Unfortunately, Marie-Thérèse and her parents were driving home from a very late party in another white van, and someone fired a rocket launcher at the wrong vehicle. Her parents were both killed instantly, but Marie-Thérèse, who was asleep in the third seat, was blown clear and survived with only scratches.

“She retreated to her Cairo home and became reclusive, but she was bitter about her parents’ death. She refused compensation from all three governments, but then she was a wealthy young woman, having inherited two large houses and her father’s considerable fortune.

“She had a boyfriend, an Irani, whose politics extended to extreme violence, and we think she was recruited by the boy and sent to a terrorist training camp in Libya, where she made contacts among others of her kind from Ireland, Japan, Germany, and God knows where else.

“She was trained in firearms, explosives, and chemical weapons, but her handlers, when they learned of her language skills, thought her meant for better things. They taught her assassination skills, document forging, and just about anything else a budding terrorist could possibly want to know, keeping her interest by telling her they would help her find the people responsible for her parents’ death so she could kill them. She also became very physically fit in the desert, and she’s known to work out almost obsessively, wherever she goes.

“When she finished her schooling in Libya, she returned to Cairo, then Zurich, selling her two houses and secreting the money in accounts around the world. Some say her holdings ran to several tens of millions of dollars. She returned to Cairo and, in effect, ceased to exist. The little we know of her since then comes from rumors and a couple of very aggressive interrogations of people who knew her.
