Psycho - Robert Bloch

The story was all too real-indeed this classic was inspired by the real-life story of Ed Gein, a psychotic murderer who led a dual life. Alfred Hitchcock too was captivated, and turned the book into one of the most-loved classic films of all time the year after it was released.
Norman Bates loves his Mother. She has been dead for the past twenty years, or so people think. Norman knows better though. He has lived with Mother ever since leaving the hospital in the old house up on the hill above the Bates motel. One night Norman spies on a beautiful woman that checks into the hotel as she undresses. Norman can't help but spy on her. Mother is there though. She is there to protect Norman from his filthy thoughts. She is there to protect him with her butcher knife.
