Psycho: Robert Bloch

The book is SOO much better than the movie, if you didn't know Norman Bate's mother was not alive and stuffed, the moment of realization would be amazing in the story. A woman steals money from her employer to try to help a boyfriend out of debt so they can get married, but gets lost on the way. She spends the night in the Bates hotel where she is senselessly murdered. Her sister goes on her own investigation to find her knowing something horrible must have happened. Norman kills a detective and tries to kill the sister who is finally saved by the sister's boyfriend and the small town cop.
