Picture book mystery that's fun to solve together.
Older kids -- the target age for this book -- can keep busy aiding Bertie the Badger in his efforts and won't be discouraged by the rich vocabulary in the rhyming text. But don't dismiss this title for the little kids. While they may not be able to sit for the story and they likely won't be able to solve the mystery (at least not without help), they will still enjoy the pictures, which are always interesting but never scary. And they're sure to be intrigued by the idea.
