A sudden snowstorm traps the Aldens in a mountain cabin! The cabin is cozy, but the children hear strange noises at night and find a coded message carved into the closet door. Can the children crack the code and solve their snowbound mystery?

At the beach, Benny finds a valuable gold locket and decides to try to find its owner. Soon the children are caught up in a puzzle involving strange visitors at the beach and the mysterious Miss Smith, who seems to live along in the big Tower House nearby.
