Philippa Gregory on Historical Fiction

The Boston Globe has a (brief) interview with Philippa Gregory:

The way I write historical novels is that I research and research so that I could write a book of straight history. Then I put my novelist hat on and inhabit the private life of these people until I can convey the feeling to the reader that they are really there. All characters are at one level unknowable, all you can do is look at their actions. But I haven't received any criticism.
