Detective Gordon is getting on in years but he's still the best detective around. When he discovers a young mouse who steals a single nut out of hunger, he decides that instead of arresting her, he should take her on as an apprentice and give her food and shelter. They work together to solve cases around town. It's a funny book with a lot of heart and it would make a great read aloud. My favorite part is how particular he is with his stamp. It reminds me of when I let kids stamp their library books.
