Dementia 13 (1963)

While out rowing in the middle of a lake after dark, John Haloran and his young wife Louise argue about his rich mother’s will. Louise is upset that everything is currently designated to go to charity in the name of a mysterious “Kathleen.” The argument, combined with the exertion of rowing the boat, causes John to have a heart attack. He informs Louise that, should he die before his mother, Louise will receive none of the inheritance, after which he promptly dies. Thinking quickly, the scheming Louise dumps his fresh corpse over the boat’s side, where it sinks to the bottom of the lake. Her plan is to pretend that he is still alive so that she can ingratiate her way into the will. She types up a letter to her mother-in-law, Lady Haloran, inviting herself to the family’s castle in Ireland while her husband is “away on business.”
