Describe how Suspense is created and maintained in Alfred Hitchcocks Psycho.

…

…splendidly frightful shower scene, the detective's murder in the Bates mansion and the discovery that Mrs. Bates is not quite who she appears to be. Looking back, "Psycho" is magnificently well written with witty symbolism and subtle sinister conversations setting up the horror magnificently. I feel that the greatest aspect of this film is the echoing observation that "We all go a little mad sometimes" after the implicating voyeurism of this dark and disturbed masterpiece.
