Harold has a younger brother, George, who has exhibited psychopathic tendencies his whole life. When George commits an unspeakable act of violence, Harold is thrust into being responsible for George’s two children, a responsibility for which he is woefully unprepared. Initially Harold is very annoying because of poor impulse control resulting in very bad decisions, especially with his relationships with women. However, he slowly grows into his role of protector and confidant. The setting is NY with an interesting excursion into South Africa. This is a very good book about how complex behaviours can evolve. A sub-plot about Richard Nixon is totally entertaining.
