Killing Commendatore by Haruki Murakami

This is a wonderful book.  I have always liked this author, and he not uncommonly writes books that are very long and involved, describing each and everything that happens in exceptional details.  The Japanese animated films from Gibly Studios have this same quality, where each leaf on each tree is carefully rendered in such a way to create a lush background, and this book shares that quality.
The book centers around the experiences of a 36 year old painter.  We know from the very beginning that his wife asks him for a divorce and then comes back to him.  We also know from the beginning that he comes out of this okay because he lives to tell the tale, which is important as this is not so much an action adventure story as it is one of magical realism.
When his wife tells him she is having an affair with someone, he leaves immediately, and a long-standing friend lets him live in his fathers house and studio.  The father was a very famous painter, and the spirit of that painter is still very much in the house.  He meets a man who is much like Gatsby, rich and soulless. who acts as the unleasher of spirits in the tale, sets balls in motion that cannot be stopped, and it is a fun and varied ride.
