It is the holiday and Joe, Tom and Pip are back with granny in Muddlemoor. And Muddlemoor is still a hotspot for crime.
When the kids discover that a dangerous gang of robbers is hiding in the area they start an investigation straightaway. But hang on a sec…Granny’s Book Club seems to be acting rather suspiciously. For one thing the never talk about books and for another thing they keep going on about a local bank.
Oh no!! What if Granny’s Book Club are the true life robbers?
