<i>A Parasite in the Mind</i> is the second volume in the acclaimed <i>Eat the Evidence</i> trilogy by John C. Espy, which follows the story of a violent serial pedophile and murderer, Nathaneal Bar Jonah, from birth to death on a torrent of pedophilic and homicidal mayhem. It does not attempt to take the reader inside the mind of a serial killer, rather it attempts to take the serial perpetrator into the psyche of the reader. This allows the reader to experience a portion of the psychic primitiveness that a serial perpetrator uses to ensnare his victims. The books were compiled from hundreds of hours of interviews and more than a hundred thousand pages of court documents.
