Abstract
As proposed in the classic work by Hervey Cleckley, M.D.— The Mask of Sanity—a psychopath typically meets sixteen diagnostic criteria. Every one of them applies to Richard Hickock as he is revealed by Truman Capote's In Cold Blood, a nonfiction novel about the murder of Kansas farmer Herbert W. Clutter and his family forty years ago. It transcends the boundaries of traditional journalism by closely examining the entire constellation of antisocial personality traits that Hickock exhibits. Drawn in large part from jailhouse interviews, Capote's portrait of Hickock breathes life into the psychiatric literature, thus rendering intelligible the mental evaluation provided by the physician who examined the accused in preparation for his upcoming trial. In so doing, Capote's best-selling masterpiece serves as a case study of a psychopath, one that conforms to established medical authority while maintaining its popular appeal.
