Mr Grunt`s a man with a mission. He has to get a Person of Great Importance (or POGI) to someone called Mrs Bayliss by the twenty-fifth. Alive & well. & he can`t tell anyone more than that, not even his lovely wife, Mrs Grunt, because there will be people trying to snatch the POGI & so the POGI must be transported in secret. It`s an exciting adventure, but what interests Mr Grunt most are the silver coins he`s been promised at the end of it. The Grunts` stolen son, Sunny, has a few questions. Who is the big-earringed cyclist? Why does the POGI have to wear a barrel all the time? Is Rodders Lasenby a lovely person or simply the rudest man on the planet? & how long will it be before they find themselves All At Sea?
