'You? Loudmouth Louis Todd? Stay quiet for even one hour?' Everyone knows Louis is a chatterbox. He can't stay quiet for even a minute. So no one believes him when he says he's going to do a sponsored silence. They don't think he can possibly do it. Not his teacher, nor his school chums and certainly not the dinner ladies - they bet five million pounds each.
But Louis thinks just for once he might be able to keep his mouth shut all day! Will he manage it?
