Psycho II is a 1982 novel that Robert Bloch wrote as a sequel to his 1959 novel Psycho. The novel was completed before the screenplay was written for the unrelated 1983 film Psycho II. According to Bloch, Universal Pictures loathed the novel, which was intended to critique Hollywood splatter films. A different story was created for the film and Bloch was not invited to any screenings. Universal suggested that Bloch abandon his novel, which he declined and released anyway to good sales.
