This was such a good fun!! The Five Fine Outers is my favourite mystery series of Miss Blyton. They are genuinely good mysteries and pack hilarious moments with Mr Goon, the local policeman. The mystery in this book appears very late which meant most of them first half of the book is just plain fun the children have with Goon!! One the mystery heats up, for a while it appears Mr Goon might just turn one on Fatty for once but gets finally trumped again. Happiness!
