Trust Me I'm a Troublemaker

Archie is a very mature child — some would say far too mature! Having grown up with his gran, he seems to have acquired some adult ways — and the kids at his new school find them unbearable. Especially Miranda — the class troublemaker. At first she absolutely can't stand Archie but then she starts to see him as a bit of a project... could she really make Archie into a Troublemaker Extraordinaire?
