This Matheson wasn't nearly as good as I Am Legend, but it was an all right haunted house tale. Jackson's The Haunting of Hill House is a ton better if you're in the mood for a good haunting. Hell House is all right, but Matheson takes much too long figuring out the "riddle" (revealing the gag), and by the time he does, I really didn't care that much. Also, because of the nature of this particular haunting--a perverted guy turns his ridiculously opulent estate into a den of sexual iniquity--many of the poltergeists are depraved and creepily sexual, and not in a fun way. Readers, you can do better.
