Summer vacation on an almost private island gives the Aldens a challenge. Henry, Jessie, Violet and Benny used to live alone in a boxcar. Now they have a home with their grandfather and are spending the summer on their own private island. There is a mysterious stranger on the island with a secret--but that's not the only surprise in store for the Boxcar Children.

In this story about the Boxcar children, the Aldens find a castaway on a South Sea island, and must then find out how he got there and how they can help.

Colorfully illustrated retelling of Aesop's fable in which a boy tending goats on a lonely mountainside thinks it a fine joke to cry "wolf" and watch the villagers come running--until the day a real wolf appears and no one answers his call.
