Yours Truly
This author wrote a short story in which a man makes a deal with the devil to obtain a watch that will allow him to stay forever in the happiest moment of his life, but, unable to choose such a moment, he doesn't use it until after he has boarded the title conveyance. This author of "That Hell-Bound Train" suggested that a certain serial killer murdered his victims in order to achieve immortality in his story "Yours Truly--Jack the Ripper". He is best known for a novel in which an investigator arrives in Fairvale to look for $40,000 stolen by Sam Loomis' girlfriend but is murdered by the same character who murdered her. That character is eventually revealed to suffer from a split personality which resulted in him dressing up as his mother. For 10 points, name this author who wrote about Norman Bates in his novel Psycho.
