Mandy killed her uncle. It was afternoon when Carrie looked out the bay window
and saw the sunset, so the window must have been facing the west. However, Mandy
claimed to have seen the sunrise through that same window, but the sun rises in the east.
Carrie learned from a distraught Mandy that they had argued recently, and she had come to
settle their dispute, although Steven had already disowned her and refused to re-include her in
his will, so, in a fit of anger, Mandy shot him with a revolver hidden in a kitchen cabinet for
safety precautions. Her uncle had also fancied a drink and was on his way down to the kitchen
when she was taking her glass of water back upstairs.
