Her second marriage collapsed in the late 1980s, because Claus wanted to return to Europe and she did not, and shortly afterwards she met Chris Whittle, her current husband, an education entrepreneur who founded Edison Schools, a commercial company that manages US public (ie, state-funded) schools. 'Never did I think that I was going to become an American citizen and stay in New York, but I did. We've been married 20 years.' With him, she has two daughters, Andrea and Sasha, and the family settled in Carnegie Hill, on Manhattan's Upper East Side ('because I wanted my kids to be able to walk to school'). They also have a house in the Hamptons at Georgica Pond, the 290-acre coastal lagoon that counts Steven Spielberg, Martha Stewart and Calvin Klein among its lakeshore residents. 'It's my equivalent of the Greek place where Italians go to holiday,' she explains. The family spend as much time there as possible and it is where Luna and Lola had their happiest times. 'Luna chased birds along the pond,' Priscilla writes in the book, 'while Lola dug rabbit holes.' Now her son Maxi, 24, is working as a private-equity analyst, Andrea, 19, is at university, and Sasha, 15, is at high school. 'She's spending a semester in the Bahamas, so it's the first time in 21 years that I don't have anyone at home. It's strange.'
