If you like his book "The Art Thief", I would also recommend "The Art Forger" as well. In the Art Forger, they reference famous forgers and their actual methods. The book goes into pretty deep detail about certain methods that forgers use. If you're an art person, it's pretty geeky. It uses the unsolved heist at the Isabella Stewart Gardner Museum as a backdrop for the main story line.
