3 1/2 stars. This was a fun adventure for kids, set in an Enid Blytonesque world. It has the elements you would expect in a story of this genre, absent parents, kids outwitting the adults, suspense and a mystery to solve. There were a number of coincidences that for an adult were hard to believe, but these shouldn’t bother kids. And there were a surprising number of people who fell over and hurt their ankles. It was a rather overused plot device. I enjoyed reading this and look forward to further instalments.
