The House of Mystery Radio Show has been on the air for ten years, broadcasting in over a dozen cities in the U.S. It started as a way to interview guests knowledgeable in many of the world's mysteries involving crime, science, religion, history, the paranormal, conspiracies, etc. This book reviews the D.B. Cooper case. It is divided into five parts. The first part gives the bare facts we know about the hijacking. The second part covers the primary suspects listed according to the FBI, media, or public opinion, supported by the show’s best interviews with authors and researchers who covered these suspects. The third part covers the other major suspects popular among the public but not considered Cooper by the FBI or law enforcement authorities. The fourth part covers some of the major suspects who came forward to police and confessed to being D.B. Cooper. The last part is dedicated to the wave of copycat hijackings that occurred after the Cooper case. And there were quite a few.
