Grandma Dangerous and the Egg of Glory

Synopsis

A priceless artefact has been stolen in Russia - and Grandma Dangerous wants to find it. Nothing will stand in her way - not even some poisoned caviar, a prison break or a spot of contemporary dance. Can Ollie and Grandma return the treasure and get back home, before being caught by the politsiya? Or - worse - before Mum finds out?
