Psycho, by Robert BlochRead about the other entries on the list.
Although Hitchcock’s film adaptation has eclipsed Bloch’s novel, the book remains a tense psychological thriller. If you think the idea of a disturbed man murdering people and keeping the mummified corpse of his mother seated in his house, where he frequently has conversations with her, to be a bit out there, consider the real-life serial killer the story is based on: Ed Gein, who made “clothing” out of human skin taken from his victims in order to create a “woman suit” he could wear so he could pretend to be his own mother. Bloch claims he wasn’t aware of Gein until the novel was almost completed, but the details are so similar it seems like too strong a coincidence.
