O'Brien, Christopher: - Christopher O'Brien has devoted 20 years to investigating and researching hundreds of these unexplained livestock deaths and assessing the potential implications for humanity. With the help of a handful of unsung "mutologist" proto-scientific pioneers, O'Brien has synthesized an insightful explanation that may help explain this puzzling mystery-a mystery that may have profound implications for our rapidly-growing beef-eating culture. He is the author of the books Secrets of the Mysterious Valley and Stalking the Tricksters, among others.
