I thought that this book was awesome because it is funny when Eric, by accident, bought a dog whistle and did not know it was a dog whistle. I liked the part when Cam and Eric were at the milkman's house spying on him. They left their bikes outside where the milkman could see them. I was thinking, will the milkman pass them and discover Cam and Eric spying? It was very suspenseful and exciting.
I recommend this book to people who like mysteries. There are many suspects which makes the book interesting and fun.
