Psycho

Psycho has the constant element of what is going to happen, curiosity, suspense and tension build as the film progresses. The story is all a Maguffin we are originally led to believe  that the money stolen at the beginning is the reason for things happening, however the plot unravels and the story is really about a motel owner Norman Bates a man with a deranged mind that shows a twisted ill side of him.

Sweaty, leery, cowboy-hatted businessman Tom Cassidy has come into the office of a Phoenix realtor, George Lowery, to close a house purchase in cash: an ostentatious wedding present for his 18-year-old daughter, due to get hitched the next day.

He boasts to the secretary, Marion Crane, that the $40,000 he's waving under her nose has been amassed without reference to the tax authorities. He even brags that he never carries more than he can afford to lose. In a shrewd instant, Marion reaches a conclusion Hitchcock cleverly never spells out. If she steals his money, he can take the hit and won't call the cops because that would alert the IRS. She's right. As things turn out, Cassidy only engages a private detective, the stolid Arbogast. 

Lost and disorientated on the rainy highway, runaway Marion winds up in a remote motel – not so different from the hotels where she enjoyed furtive lunch hours of passion with her lover. It is run by a strange taxidermy enthusiast, Norman Bates, played by a saturnine Anthony Perkins.
