In the horrifying annals of American crime, the infamous names of brutal killers such as Bundy, Dahmer, Gacy, and Berkowitz are writ large in the imaginations of a public both horrified and hypnotized by their monstrous, murderous acts. But for every celebrity psychopath who's gotten ink for spilling blood, there's a bevy of all-but-forgotten homicidal fiends studding the bloody margins of US history.

In Sons of Cain - a book that fills the gap between dry academic studies and sensationalized true crime - 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 further back into human history and deeper into the human psyche than Serial Killers - Vronsky's 2004 book, which has been called "the definitive history of the phenomenon of serial murder" - he focuses strictly on sexual serial killers.
