"What Maisie Knew", the only Henry James book I've ever read, is very worthwhile reading for family lawyers or anyone else interested in divorce and child custody. It reminds us how long these horrible situations have been going on, and that it's not human nature that has changed, but the circumstances in which the better or the worse aspects of human nature are allowed and encouraged to be acted out. (My 1950s copy is illustrated by Edward Gorey!)
Now it's a movie, and whether you see it or not, and/or read the book, this review by A.O. Scott is a good place to start.
