Though we may like to believe that murderers are pathological misfits and hardened criminals, the vast majority of murders are committed by people who, until the day they kill, would seem to be perfectly normal. The Murderer Next Door is a riveting look into the dark underworld of the human psyche, an exploration of when and why we kill and what might push any one of us over the edge. A leader in the innovative field of evolutionary psychology, David Buss conducted an unprecedented set of studies investigating the underlying motives and circumstances of murders, from the bizarre outlier cases of serial killers to those of the friendly next-door neighbor who one day kills his wife.

Reporting on findings that are often startling and counter-intuitive, he puts forth a bold new general theory of homicide, arguing that the human psyche has evolved specialized adaptations whose function is to kill. Taking readers through the surprising twists and turns of the evolutionary logic of murder, he explains exactly when each of us is most at risk, both of being murdered and of becoming a murderer.

Featuring gripping storytelling about specific murder cases, The Murderer Next Door will be necessary reading for those fascinated by books on profiling, lovers of true crime and murder mysteries, and readers intrigued by the inner workings of the human mind.
