Emme, Holly and Jess are just like regular girls, always messing and having fun. But they're also fairies, and instead of regular schooling they go to friendship classes and then they're sent out into the human world to teach children what they've learned. Of course, it's not always easy! Will they ever be able to graduate from fairy school?
When Daisy Wells and Hazel Wong set up their very own secret detective agency at Deepdean School for Girls, they struggle to find any truly exciting mysteries to investigate. (Unless you count the case of Lavinia's missing tie. Which they don't.) Then Hazel discovers the Science Mistress, Miss Bell, lying dead in the Gym.
