The book is rich in case studies and anecdotal examples which are analyzed effectively to illustrate sexual murder as a typology ranging from one time "catathymic" homicides to repeated compulsive killings. Additionally, the book chronicles historical and theory driven developments in the understanding of sexual homicide going as far back as folklore regarding man-like monsters who've killed local villagers to classic sociological and psychological theories of crime. However, Dr. Schlesinger is a psychoanalyst at heart and largely attributes the motivations (which is iffy to begin with) of such individuals to a pervasive psychosexual frustration, which can be tiresome for those who want less armchair psychoanalysis. Overall, an incredibly insightful read, but can be grueling at times given the nature of the content, so be prepared to read some things you might wish you hadn't.
