Query: Angels and Demons

Angels and Demons was a quick-paced and thrilling read. Dan Brown is a master at creating cliff-hangers at the end of his chapters that make you want to keep turning the page. I just had a little trouble with the ending of the book. It seemed to me that you really had to suspend belief to accept that all of the events could occur in such a short time-span without the "hero" being beaten to a pulp.
