The Otterbury incident

It all begins when Nick breaks the classroom window with his football, and the Headmaster says Nick has to pay for the damage. Nick has no more hope of raising the money than of going to the Moon, so that's when Ted's and Toppy's gangs decide to sign a truce and plan Operation Glazier to get the money for Nick. The plan goes smoothly and soon the money has been collected, but when it goes missing the boys turn detective to try and find the culprit.
