Query: A poor novel

I read DaVinci Code and Angels and Demons, and loved them both. This book fell FAR short. The plot twists are very clumsy and obvious. The plot revolves around cryptography and the internet. Brown made two flaws (well, the same flaw with two facets) he included too much detail in the methods that the technology in his plot used. For people who are technical, and understand how cryptography actually works, the book is painful to read, because he has major fundamental flaws with the way that crypto works. Suspension of disbelief is totally trashed. For people who aren't technical, the details he includes add no value, and are too confusing to understand. If he had been more vague, both groups would have been better off.For a book that deals with the subject of crypto intelligently, go with Cryptonomicon, by Niel Stephenson.
