When you were a kid, did you ever flirt with the idea of “running away from home and joining the circus”? Have you ever seen a magic act and wondered if it was real, or if it was just a clever parlor trick? Todd Robbins, currently the host of the TV series “True Nightmares” on the Investigation Discovery Channel, divulges the secrets of the dark worlds of sideshows, magic, con artists, séances and the circus in his book, The Modern Con Man: How to Get Something for Nothing. In the 3rd hour of the broadcast, Brandon Callahan, author of The House Where Evil Lurks: A Paranormal Investigator’s Most Frightening Encounter, joined us for a fascinating discussion on hauntings and poltergeists.
