In my pile of to be released after I reads.

This book is very interesting. It is a journalistic type book about the psychology of the serial killer. Be warned that it is very explicit in parts and may turn your stomach. As an account of the history of the phenomenon it is very interesting. It covers the lives and deeds of several famous serial killers and has photos of them in the centre of the book.
It started out a bit dry but about a third of the way through it got really interesting, the last third I whipped through.
Of course you have to be really into this kind of thing to want to read it.
