Query: The Great Brain's swindles are great fun to read about.

I think this a great book. It is about a boy named Tom that everyone called the great brain. He was very smart and liked to outsmart other people, but only if he got money for doing it. He could outsmart every kid in town and most adults. The Great Brain wasn't very likable--he took people's things, especially money, and he made fools of people. But what he did was entertaining. He put his great brain to work on how to swindle someone to get what he wanted. What motivated him to do this was his money loving heart. In this book he is involved in the buried treasure swindle, the horse race, and the chute the chute (a thrill ride). In all of those he gets money. I really think you should read his book because the characters each have an interesting, believable personality, The swindles he pulls off are fun to read about, and it is a really funny book.
