I mean, if you pause over what it means at the age of 76 that Eleanor Roosevelt wrote, the happiest single day of her life was the day she made the first team at field hockey. Field hockey is a team sport. Field hockey is a knockabout - I mean, picture Allenswood, the swamps of north London. It's a messy sport. So she really enjoyed playing this rough-and-tumble sport in the mud of Allenswood, a team sport. And she was very competitive. And she loved being competitive, and she loved to win. And that, I think, was all of the things that Allenswood enabled.

I mean, her father was an alcoholic, and her mother was the suffering wife of a man who she could never predict what he would do, where he would be, who he would be. And it's sort of interesting because Eleanor Roosevelt never writes about her mother's agony. She only writes about her father's agony. But her whole life is dedicated to making it better for people in the kind of need and pain and anguish that her mother was in.

I think that, very often there's a pain that's just too painful to touch. You'll break apart. And I think her mother's death and disappearance and abandonment was something she just never could deal with. Eleanor Roosevelt, when she's really very unwell in 1936, she takes to her bed. She has a mysterious flu.

I think that Hick was in love with Eleanor, and Eleanor was in love with Hick. I think it's very important to look at the letters that are in my book, because unlike some of the recent published letters, I have both the personal and the political. And their relationship is about ardor. It's about fun. And it's also about politics.

Eleanor Roosevelt never thought that she was attractive. She never thought that she was really sufficiently appealing. And I think her whole life was a response to her effort to get her mother to pay attention to her, to love her, and to love her as much as she loved her brothers.

I think her Grandmother Hall gave her a great sense of family love, and reassurance. Her grandmother did love her, like her father, unconditionally. And despite the order and the discipline - and home at certain hours and out at certain hours and reading at certain hours - there was a surprising amount of freedom. Eleanor Roosevelt talks about how the happiest moments of her days were when she would take a book out of the library, which wasn't censored.

I think Eleanor Roosevelt always had a most incredible comfort writing letters. I mean, she was in the habit of writing letters. And that's where she allowed her fantasies to flourish. That's where she allowed her emotions to really evolve. And that's where she allowed herself to express herself really fully, and sometimes whimsically, very often romantically. And it really starts with her letters to her father, who is lifelong her primary love.
