Another hilarious and moving novel from the critically acclaimed author and natural successor to Roald Dahl. A story of prejudice and acceptance, funny lists and silly words, this exciting book has all the hallmarks of David Walliam's previous bestsellers. Ben's grandma may seem incredibly boring on the outside, but this old lady was actually once an international jewel thief, and she's been busy masterminding a plot to steal the crown jewels, with Ben's help of course.
