The Da Vinci Code was an interesting book, full of theories about the life and secrets of Leonardo DaVinci. Many of the theories surrounded the mysteries of Christianity. One of the most interesting parts of the book was the story behind the painting of the Last Supper. It is interesting because you can actually look at the painting and see the details talked about in the book.
I think the book was great entertainment, but I would not take any of the theories or stories too seriously. The book may have been based on conspiracy theories but it is still a work of fiction.
