When Daisy Wells and Hazel Wong set up a secret detective agency at Deepdean School for Girls, they can’t find a truly exciting mystery to investigate. Then Hazel discovers the body of the Science Mistress, Miss Bell – but when she and Daisy return five minutes later, the body has disappeared. Now the girls have to solve a murder, and prove a murder happened in the first place, before the killer strikes again (and before the police get there first, naturally). But will they succeed, and will their friendship stand the test?

Having heard great things about this series of books, I finally sat myself down to read the first one (you should normally start at the beginning in my opinion). It does not disappoint in any way. Like all good mysteries, there are plenty of suspects all with their own motives for wanting Miss Bell out of the way. Our main characters, Daisy and Hazel, are both likeable and relatable although their friendship will be put to the test as they struggle to pin down the culprit! This story is full of twists and turns as well as plenty of cake and biscuits, and will keep you guessing until the end.

If you are not sure that a mystery book is your thing, why not use your World Book Day voucher and see if you enjoy them, as Robin Stevens has written a special story just for this year’s collection of £1 books. Happy sleuthing!!
