Pulitzer Prize nominee Dr Christopher J Kurtz and co-author Robert D Hunter may have the answer to this question. Over several years they have corresponded with a number of convicted killers who have told of their compulsion to commit serial homicide. their unique insights into the lives of these deranged individuals have allowed them to explore in disturbing detail the homicidal manifestations of a number of mental afflictions, including fantasy addiction and narcissistic personality disorder. Their conclusions make for a frightening reading, but Kurtz and Hunter argue that we must delve into the twisted world of evil and irrational if we are ever to understand the serial killer and his motivations. Dark Truths not only provides an in-depth study of the terrifying obsessions of serial killers and rapists, but it is also a compelling study of alienation and psychosis that lurk just beneath the surface of modern society.
