I interviewed Louise Erdrich about 20 years ago, a year or two after she'd gone through a messy time in her life. She had just published the first book after her husband/mentor/writing partner had committed suicide. Which happened not long after she'd gone to the police and accused him of physically and/or sexually abusing some of their six kids. I knew I had to ask her about that, and I knew she'd probably say "no comment." Still, I was really nervous about it. But it went exactly as I had expected and we just went on to talk other stuff: her new book and her bookstore in Minneapolis and the new baby she'd just had with a person whose identity she did not disclose.
One thing she said that was weird was that she wrote a scene in which a character in the new novel, a priest who had appeared in a previous novel, undresses and is revealed to be a woman pretending to be a man. Louise said she did not know until she wrote the scene that was going to happen, so she was as surprised as anyone when it did. That struck me as disingenuous. I would believe it didn't occur to her to have that happen before she started writing, but I didn't think it was possible for her fingers to start typing on their own (or writing longhand, if that's what she does) as she watched the scene unfold like someone in the audience at a movie.
I loved her first three novels and read a couple of others but after a while stopped trying to keep up with them.
