Hush...Hush, Sweet Charlotte (1964)

Aged, wealthy Charlotte Hollis has lived as a recluse in the crumbling family plantation mansion in Hollisport, Louisiana since her father Sam Hollis' death thirty-six years ago. The only people who regularly see her are her hard-as-nails but seemingly loyal housekeeper, Velma Crowther, and her longtime friend and physician, Dr. Drew Bayliss. She has lived there most of her life except for a short stint in London thirty-seven years ago following the vicious murder of her lover, John Mayhew, at the plantation's summer house while Sam was hosting one of his legendary grand balls in the mansion. She and John had planned to run off together that night, but instead he was bludgeoned to death. Nobody was ever convicted for his murder, but most people believe Charlotte did it. They also believe that Charlotte, whom they haven't seen in years, is a crazy old woman. Conversely, Charlotte has hidden away fearing that people would always be glaring at her. Charlotte is surprised that her younger cousin Miriam Deering has accepted her invitation to stay at the mansion. While Charlotte wanted Miriam to help her overturn the expropriation with the state government in Baton Rouge. By this time, Charlotte's mental state seemingly hits a sharp decline, perhaps because she would be leaving her family home, but could it be issues surrounding John's murder?
