Puzzling People: The Labyrinth of the Psychopath

I have to agree with many of the other reviews. The book seemed well researched and then became really strange towards the end (global conspiracies? really?). The first three quarters are definitely worth reading though. Just a warning: the author repeats himself a lot and the editing isn't very good (plenty of missing words). So if things like that distract or annoy you, don't bother with it.
