The Ghost of Fiddler's Elbow

When Marcy and Colin visited their Uncle Fred's farm, they found a sharp bend in the river called Fiddler's Elbow, where, it was said that the land, the river and time all bent back on itself. Uncle Fred said it was all nonsense, but Marcy and Colin didn't think so after getting a ride from a U.S. Mail wagon that hadn't been in service for nearly 100 years.
