Working a comics convention into a book is always fun, and the author is especially nice to Jimmy. Evans' sons actions are a bit over the top, but ultimately understandable, and the resolution is satisfactory. As always, Jimmy's parents are supportive of his actions and accompany him on this trip, even though they are a bit disappointed about the incident with the cafeteria lady.
Stower's illustrations are a nice touch, and their inclusion makes it easy to hand this book to readers who have read all of the notebook novels available and are able to move onto books with slightly more text. Hand this series to fans of clue oriented mysteries like the Hardy Boys or Ron Roy's various beginning chapter books, and make sure they've read the first three books in this series: My Dog is Better Than Your Dog, It's a Doggy Dog World and Dog Day Afterschool.
