My favorite part of the story is when they use different clues (like get everyone in a line and a boy pretends that he is not the one that did it) to solve the mysterious case of the missing mitt. I also really liked this book because I like going to baseball games and I also like books that are mysteries. My other favorite thing about the story is that the setting is in a baseball field. I like the setting because my favorite sport is baseball! My favorite characters in the book are Frank and Joe because they are the ones that end up solving the mystery and finding the mitt.
I would recommend this book to any third grader. I especially think that third graders that like clues and mysteries would enjoy reading this book. This book is so good; it will make you want to keep on reading!
