"The Black Book of serial killers" for me is THE book that gives you an image of the human being as it may be, without taboo. I spent hours devouring the atrocities of these men and it is frightening. We realize that the human being is capable of atrocity and that the serial killer are very far from the image of the American series, so if you're curious like me, no hesitation. In addition, the book is thick enough good "fun".
