Doris Force at Raven Rock

Doris Force, her friends, and Mrs. Mallow prepare to travel to Raven Rock where Uncle John Trent and the Gates sisters hold the deed to a property. Before they can depart, the deeds are stolen, and since the land claim has not been officially recorded, anybody who possesses the deed can claim ownership of the land. They rush off by plane, and on the way the pilot discovers a stowaway. Doris suspects that he may be involved in the plot to steal her Uncle John's land. Although she and her friends arrive at the property first, they are unable to claim the land. The schemers stake their claim, and Doris must find a way to get the deeds back from the trespassers so that she can claim the land for Uncle John and the Gates sisters.
