If Tim and Alex’s story sounds eerily familiar to fans of The Americans, the television drama about a KGB couple living in the US with their two children, that’s because it’s partly based on them. The show is set in the 1980s, providing a cold war backdrop, but the 2010 spy round-up served as an inspiration. The show’s creator, Joe Weisberg, trained to be a CIA case officer in the early 1990s and, when I speak to him on the phone, tells me he always wanted to put family at the heart of the plot. “One of the interesting things I saw when I worked at the CIA was people lying to their children. If you have young children, you can’t tell them you work for the CIA. And then, at some point, you have to pick an age and a time, and they find out that they’ve been lied to for most of their lives. It’s a difficult moment.”

When I meet Alex in Moscow, he has just finished watching the first season. (He had started on previous occasions, but found it too difficult; he and Tim joked that they should sue the creators.) His parents like the show, he tells me. “Obviously it’s glamorised, all this killing people and action everywhere. But it reminded them of when they were young agents, and how they felt about being in a strange new place.” Watching it, Alex says, has made him more curious: what set his parents off on this path, and why?
