Red leaves—yellow leaves—orange leaves. It is a beautiful Indian summer, but strange things are happening in Cranberryport.

At Grandmother's house, on the edge of a cranberry bog, a priceless copper kettle disappears. A gold weather vane is gone from the town hall. Then, old Mr. Whiskers discovers that this greatest treasure, the carved figurehead named Annabelle, is missing.

The sheriff orders the entire force into action, but Mr. Whiskers and Maggie decide to track down the thieves themselves. They set sail for a deserted island where they have a hunch they might find clues to the missing treasures. But they soon find themselves stranded there as they see a stranger towing their boat away from the shore. Danger and excitement abound as Mr. Whiskers and Maggie use their special brand of ingenuity and cunning to catch the thieves.

This light-hearted adventure is the third in a series of well-loved Cranberryport series which have been translated into many languages and read by millions of children throughout the world. Once again, as a special bonus, the Devlins have provided a recipe—for a delicious cranberry pie-pudding.
