Grandma Dangerous and the egg of glory

WARNING: DO NOT GIVE THIS BOOK TO YOUR OWN GRANDMA. SHE MIGHT GET IDEAS... Grandma demands justice!* *And also all the teacakes 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? Praise for Book 1: "Thrills! Biscuits! This book has it all" Andy Riley, author of King Flashypants
