The story that Rowling had begun to write on the train that day was about an orphan boy. I slightly glibly used the trope for six months before my mother died. To me this decade now was infused with loss. Perhaps that would have colored my feelings about the story I was writing. But in fact, that sense of loss and this real despair that I felt started to go into the story. The thing that interests me most is human nature, above anything else.
