This book is a real whooo-whooo-dunit! Wallace and Grace are owls and run the Night Owl Detective Agency. In Wallace and Grace and the Cupcake Caper by Heather Alexander, the best friends use evidence and clues to find the culprit who stole Monty the Chipmunk's cupcake.
So far, there are two books in this beginning reader series. Be sure to also check out Wallace and Grace Take the Case to see how the detectives solve the mystery of the spooky garden. These books are a real hoot!
