A Moscow spy worked for two decades under cover in Europe by building a fake biography. There are others.

One June night in 2010, Henry Frith asked the son of his live-in partner for a lift to Madrid airport early the next morning.

Frith didn’t say where he was flying to. He rarely did when Alejandro Valdezate Sánchez regularly drove him to Madrid Barajas international airport for one of his many business trips.

The next day, agents from the Centro Nacional de Inteligencia, the Spanish security service, came to Valdezate’s home to interview him. The conversation was calm and courteous, but one thing soon became clear to Valdezate: Frith wouldn’t be coming back. He never did.
