Here is what I remember about the old movie I'm dying to see again. I think it started with a rich elderly man in his bed at his big home, he was dying. His 3 daughters came to be with him. There was also a housekeeper or another woman (stepmother?? ) in the house. After the old man died one of the sisters drown one in the bathtub and made it look like she was drunk and it was an accident. Then she pushed the other sister down the side of a mountain and thought she was dead... she survived to tell who did it. The bad sister was trying to get all of the inheritance. That's all I can remember. I know it sounds a lot like Three Bad Sisters but its not. Help! What's the name of it? Its been at least 30 years since I saw it. I do not know any of the actors in it.
