Murder Most Unladylike Trio Award-winning author Pack by Robin Stevens (author) (UK edition)

It’s Agatha Christie meets Malory Towers – and every bit as great as that sounds. Picnics, hi-jinks and jolly evil crimes. At Deepdean School for Girls, the game is afoot. (As master sleuth Sherlock Holmes might say.) Hazel Wong and Daisy Wells have started a detective agency, and they’re waaaay busy. Yup: their cosy little world is a veritable hothouse of iniquity and crime. The cases keep coming in – dead teachers, poisoned party guests and the mysterious case of Lavinia’s missing tie. Although they’re not sure if that counts… Can Wells and Wong stay bezzies and stay sane in the midst of so much murder?
