The authors, James McCloy and Ray Miller, uncover some of the deceitful and bizarre sightings of the beast. They point out that while a few appearances have been hoaxes, and other sightings of it have been the result of mass-hysteria, the Jersey Devil has been seen by enough sane, sober, and responsible citizens to keep the possibility of its existence alive today. Many theories about the Jersey Devil’s origin are discussed and carefully reviewed and explained by the authors.
