I have read many books out there about serial killers, mass murders, as well as being a criminal justice major. The topic of perverse, hateful, and demented individuals really gets my blood flowing. Don't take that wrong of course. This book I might add does just the trick. Schechter, one of my favorite authors on the subject, leads us down a path in which there is no turning back from. Once you find out about the amazing Mr. H.H. HOlmes...the "other" serial killers look like an old pair of panties that your great grandmother used to wear. READ THIS BOOK. I am about to embark on the journey once more...because it is immensely gratifying...(if you're interested in these kooks of course!)
