Danton Cord is one of the most popular boys in MacGuffin Elementary. His friend, Iris Able, is a loner whom people think is weird. Because she doesn’t talk to anybody, the kids in school have given her the nickname “Private Iris”. However, Iris is also the smartest and most observant person in town. When the money of a class’ cashbox is stolen, Danton sees this as a chance to make people see how special Iris really is. If he can convince her to solve the crime and get the class its money back, maybe he can get Iris to be a bit more popular. But will Iris be willing to help out people she doesn’t like?
