The Brothers Karamazov
by Fyodor Dostoyevsky
One of the main characters rapes a retarded hunchback. There's also
a scene where the innocent young love interest becomes obsessed with the
idea of crucifying a four-year-old child and listening to him scream while
eating pineapple compote. Also, the ending is just weird. Nine hundred
pages of theological speculation and courtroom drama, capped off with a
boyscout meeting.
