There's nothing like kicking back in the sun and reading about serial killers and stalkers. Well, for people like me, anyway. Former FBI profiler John Douglas is of course an expert in this field and he has written several excellent books. I can't remember how many times I've read "Anatomy of Motive" but it's more times than I can count on one hand. Douglas describes different kinds of dangerous offenders, analyzes their motives and tracks the escalation of the psychopathic behavior in the cases described.

If you've got a few hours to spare, check out this captivating book.
