I read the diary when it was first published and, at the time, I was fairly convinced by it. Since that time I have become pretty convinced that it is a hoax. However it has to be said "what a hoax!!!". This book provides a very interesting account of how the pro and anti diary camps fought with each other and spent vast amounts of money trying to prove their respective cases. It won't convince believers that the diary is a fake and it won't convince non-believers that it is true but it does provide a fascinating insight into the people and personalities involved in what can only be described as a battle of principles.
