From the illustrator of the #1 smash hit The Day the Crayons Quit comes a whodunnit just right for the youngest of readers (not to mention instructions for how to build the perfect paper airplane )

The animals? homes are disappearing. Tree by tree, the forest is being cut down. Clues There must be clues. For instance, look--there is a mysterious bear carrying an ax But what would a bear want with so many trees? Perhaps the discarded paper airplanes littering the forest floor have a story to tell?

Oliver Jeffers' quirky, childlike humor and lovable illustrations are in full effect in this funny whodunit featuring a winning cast of animals and a message about the importance of conservation and recycling.
