In this third volume of the Secret Missions series, the author presents his investigation into the life and disappearance of Ambrose Bierce. Was Bierce an intelligence agent? Might he have been involved with a classified technology program dating back to the US Civil War? Was Bierce involved with the capture of the notorious Crystal Skull? Did he actually survive Mexico? Was Bierce the author of a classic 20th Century novel credited to an enigmatic author who today remains a mystery? What did Bierce know about the strange events that happened in San Bernardino just two years after he disappeared? All these questions are explored -- and possibly answered in this bridge between two fascinating series by Walter Bosley.
