Not only were their parents indeed Russian spies, they were Russians. The man and woman the boys knew as Mom and Dad really were their parents, but their names were not Donald Heathfield and Tracey Foley. Those were Canadians who had died long ago, as children; their identities had been stolen and adopted by the boys’ parents. ... Their real names were Andrei Bezrukov and Elena Vavilova. They were both born in the Soviet Union, had undergone training in the KGB and been dispatched abroad as part of a Soviet programme of deep-cover secret agents, known in Russia as the “illegals”. After a slow-burning career building up an ordinary North American background, the pair were now active agents for the SVR, the foreign spy agency of modern Russia and a successor to the KGB. They, along with eight other agents, had been betrayed by a Russian spy who had defected to the Americans. ... Nearly six years since the FBI raid, I meet Alex in a cafe near the Kiev railway station in Moscow. He is now officially Alexander Vavilov; his brother is Timofei Vavilov, though many of their friends still use their old surname, Foley. ... “They showed us photos of our parents in their 20s in uniform, photos of them with medals. That was the moment when I thought, ‘OK, this is real.’ Until that moment, I’d refused to believe any of it was true,” Alex says. He and Tim were taken to an apartment and told to make themselves at home; one of their minders spent the next few days showing them around Moscow; they took them to museums, even the ballet. An uncle and a cousin the brothers had no idea existed paid a visit; a grandmother also dropped by, but she spoke no English and the boys not a word of Russian.
