I'm not an expert on medieval France, but I sure know a heck more about it than I did before I read his. Also, I am so very glad I am not a medieval Christian woman.
That is all.
#24: John Douglas and Mark Olshaker, The Cases that Haunt Us
Speculative behavioral profiles of various notorious killers through time, from Jack the Ripper forward, with discussion of how a modern task force might have handled the crimes. Interesting and useful--I rather thought the Jack the Ripper and Lindbergh chapters were best, and the Jon-Benet Ramsay one more focused on explaining what went wrong with the investigation than what might have led to the crime. I would personally have rather had another seventy pages on the Zodiac, but you take what you can get.
