Avsnitt 3

Harriet, the older sister, is immaculately neat; Louise, the younger sister, is a slob. (think: ""The Odd Couple"".) They live together in a cliff-house in Maine. Not only does the domineering Harriet impose her tidy housecleaning habits on Louise, she tries to run her life too-- Harriet ""forbids"" Louise to date Paul Marchand . Possessive Harriet tells Louise she doesn't need men-- after all, they are sisters and will have each other forever. One day, Louise lets Harriet fall off the cliff. Now Louise can do as she likes, and date Paul; (or so she thinks). At night, a woman like Harriet goes around compulsively doing housecleaning. One day, Paul comes to the front door, asking to see Louise . Even though Louise answers the intercom, it is in Harriet's voice that she tells Paul to go away. Louise has become her dead sister. [in the character of Louise-- who adopted the habits of the person she killed-- I see a bit of Norman Bates, from Alfred Hitchcock's ""Psycho"" (1960).]
