Whatever reservations one may have about Patricia Windsor's poltergeist (see below), this is in a lesser league entirely--little more than a cleaned-up, toned-down version of The Exorcist for those too young to read the original. To wit: cousin Jason Morey comes to live with Larry and Martha Kessler bringing a classic poltergeist with him. A parapsychologist, Catholic priest and Mormon bishop all try their best to cool things, but manifestations go from bad to worse--crashing frying pans, showers of pebbles--until Wispy the dog is killed by a flying typewriter and the poltergeist cries all night in remorse. Finally Jason is taken on a camping trip where he is zapped, and cured, by a ball of lightning. Subplots include seventeen-year-old Brooke searching for and finding a boy who will love her for her mind instead of her sensuous figure, and Larry pursuing academic research on the Donner Party. The most sympathetic characters are Wispy and the lightning ball.
