The Euclid Police need a mathematician's help when a string of burglaries occurs in a very mysterious pattern. Are Dash and Rudy up to the challenge? Can Dash repair a broken relationship? Can Rudy overcome a mishap on the track? Can guinea pigs swim? Open this book to find the answers to these questions and more! And that's not all!
