Family Plot

Fake psychic Blanche Tyler and her boyfriend, George Lumley, attempt to locate the nephew of wealthy, guilt-ridden, elderly Julia Rainbird. Julia's recently-deceased sister gave the baby boy up for adoption, but Julia now wants to make him her heir and will pay Blanche $10,000 to find him. Julia knows almost nothing about the infant. During his investigation George discovers that the boy was given the name Edward Shoebridge and is thought to have died while still young. However, George tracks down a man, Joseph Maloney, who paid for Edward's tombstone years after his supposed death, and George comes to think the grave is empty. George and Blanche bicker frequently, but he is as good an investigator as she is a psychic, and their relationship is solid.
