Mr Gum is back and fancies being even more evil than usual. Read this book and you’ll meet a gingerbread man named Alan Taylor who is as rich as a mushroom. And Mr Gum and Billy William are plotting to steal his cash, right? And it’s up to Polly to save the day. There’s a funfair and hot dogs, Friday O’Leary shouts a lot, we meet a pongy Frenchman called Monsieur Bellybutton and there’s even a song about robbers called The Robbers’ Song. See ya!
