They all fall down

I stopped today in a very dramatic spot. It seems everyone is falling off of the roof. I know I've read the book before, but for the life of me I can't remember what happens next, and I'm kind of going nuts waiting to get to the part where the great fall ends. That's the sign of a good book, one that you can read over and over, and even though you remember the big details, like who lives or dies, you still read it completely enthralled by every step the characters make.
