Sammy Keyes and the Curse of Moustache Mary A quiet weekend in the country turns into an adventure when Sammy and her friends meet Lucinda Huntley walking her 200-pound pig down the road. She tells them a true story of the Wild West, and about her great-grandma Moustache Mary, and of the century-old family feud that is hardly ancient history. When Mary's pioneer cabin is burned down, Sammy is on the case.
