Are we being invaded from outer space, as many UFO hobbyists contend? Are secret government agencies tapping your phone and tampering with your mail? Does somebody else really own this earth and use it as a Disneyland of the Gods? Veteran Fortean author Keel reports with wit on the startling encounters with 'the tricksters' (so well-known to the American Indians), the Men in Black, assorted monsters, snallygasters, mothmen and weird hairy creatures that all seem to vanish into thin air. Chapters on UFO Crashes in Scandinavia, Mysterious Crime Waves, Clones, Hybrids and Sleepers, An Idaho Triangle?, Sea Monsters, The Moonstone Mystery, New Age of the Gods, more.
