Bad men do what good men dream

"What sort of person kills, then cannibalizes his victim? Or stalks and terrorizes his prey? And what separates him from the rest of us? Dr. Robert I. Simon illuminates our shadowy world and that of violent criminals - a difference more of degree than of kind." "Mental health professionals will find this updated version helpful reading. Its narrative, graphic case studies, and conclusions will interest lay readers and amateur sleuths as well."--Jacket.
