Everyone knows Roald Dahl for his children's books, of course, but for some reason I picked up his autobiographical Boy, which is a children's book for grownups, I guess you could say. It's written simply & charmingly but doesn't pull punches about the brutality of his experiences at English schools.
My mother despised him for how he treated his wife, Patricia Neal, after she had had a stroke. She could be right, I don't know much about him & I don't remember reading his books as a child. He wouldn't have been to my taste, I was a horribly refined & serious kid.
