I've loved books since I was 3, and the library was a highlight of my childhood. I've been fortunate to be able to find great joy in what others have written and sometimes to give this to readers. I follow my own muse, because it leads me on interesting adventures. I began my writing career with "Prism of the Night: A Biography of Anne Rice." I had a bestseller with "The Vampire Companion." Since then, I've published 69 books and over 2,500 articles, reviews and short stories. I have also been an executive producer for "Murder House Flip" and "BTK: Confession of a Serial Killer." From ghosts to vampires to serial killers, I have taken on a variety of dark subjects, mostly in crime and forensics. I hold graduate degrees in forensic psychology, clinical psychology, criminal justice, creative writing and philosophy. Currently, I teach forensic psychology and criminal justice at DeSales University. My books include "I Scream Man," "How to Catch a Killer", "Confession of a Serial Killer", "The Forensic Psychology of Criminal Minds", "The Mind of a Murderer", "The Human Predator: A Historical Chronicle of Serial Murder and Forensic Investigation", "Inside the Minds of Serial Killers", "Inside the Minds of Sexual Predators", and "Inside the Minds of Mass Murderers". My background in forensic studies positioned me to assist former FBI profiler John Douglas on his book, "The Cases that Haunt Us", and to co-write a book with former FBI profiler, Gregg McCrary, "The Unknown Darkness", as well as "Spree Killers" with Mark Safarik, "The Real Life of a Forensic Scientist" with Henry C. Lee, and "A Voice for the Dead" with James Starrs. I speak internationally about forensic psychology, forensic science, and serial murder, and has appeared on numerous documentaries, as well as such programs as The Today Show, 20/20, 48 Hours, NPR, Dr. Oz, Coast to Coast, Montel Williams, Larry King Live and E! True Hollywood. Currently, I'm working on a fiction series, The Nut Cracker Investigations, which features a female forensic psychologist who manages a PI agency. "I Scream Man" is the first one.
