In his book, Dutton interviews a cold-hearted lawyer who embodies psychopathic tendencies.

"Deep inside me there's a serial killer lurking somewhere," the young attorney told him. "But I keep him amused with cocaine, Formula One, booty calls, and coruscating cross-examination."

The phenomenon of psychopathy is so enticing that British journalist also Jon Ronson wrote a book on the psychopaths in our midst.

"I think my book offers really good evidence that the way that capitalism is structured really is a physical manifestation of the brain anomaly known as psychopathy," says Ronson, author of "The Psychopath Test: A Journey Through the Madness Industry" in an interview with Forbes.
