Query: Fun to Read; Lousy History

Truly a mess. No footnotes, lots of speculation, and plenty of cafeteria-style history ("I'll take one of these facts, and one of those..."). May appeal to the "rum and strumpets" fans but an absolute disaster of a 'history' book. If you want a book about the Crusades, stick with Runciman: not so much blood and garishness, but you won't be led astray. "Dungeon, Fire and Sword" is a dreadful book guaranteed to be warmly embraced by those who don't know any better.
