Excellent book. Majority of it takes place in one house, mostly in one room, with only two characters. Amazing how much intensity you can derive from such basic ingredients. I dimly recall seeing the movie, and if I recall correctly, in it Annie didn't cut off his foot, only smashed his ankles. In the book, cutting off the foot and then cauterizing it with a blowtorch is a scene I won't forget any time soon, if ever.
