50. THE MONSTER OF WALNUT GROVE
November 1, 1976
On Halloween, Laura accidentally sees Nels chop off a dolls head. She had only seen the back of the head, so she believes it to be Mrs. Oleson. Her friend, Carl, who is the only person to believe Laura, helps her search for evidence to solve the crime. Meanwhile, Mrs. Oleson has gone away so the two really think that she has been murdered. When they tell Nellie and Willie, they don’t believe them, but decide to scare Laura and Carl by saying that their father has been digging in the cellar. One night the children meet in the cellar. Nellie and Willie scare Laura and Carl, and while they are running out of the store, Mrs. Oleson comes home and everything is cleared up.
