In Sons of Cain investigative historian Peter Vronsky examines our understanding of serial killing from its prehistoric anthropological evolutionary dimensions in the pre-civilization era (c. 15,000 BC) to today. Delving back into human history and deep into the human psyche, he focuses strictly on sexual serial killers: thrill killers who engage in murder, rape, torture, cannibalism and necrophilia, as opposed to for-profit serial killers, including hit men, or 'political' serial killers, like terrorists or genocidal murderers.
