I wonder if anyone will be able to guess the book in question from the review above?I think this is Enid Blyton's only book that displays a sense of humour; I remember laughing at it when I was a child, and have introduced some 9 year-old children to it recently and they too laughed at it. As an avid reader of her books when I was young, I can't remember any others that were humorous.
I will tell you if you are getting warm or cold if you would like to take an educated guess on which book is being referred to...
