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.
