Lord Norwich's history of the papacy

John Julius Norwich has written a history of the papacy. If it remotely resembles the book that Bill Keller reviewed for the NY Times my guess is that Lord Norwich may be in for some flak from the Catholic press and blogosphere. I haven't read the book, but may look for it when it hits the local library. For the record I did find his three volume history of the Eastern Roman Empire (Byzantium) reasonably thorough and surprisingly readable given the topic. But he did demonstrate some weakness in areas dealing with complicated matters of church doctrine.
