Тайна Школы Приквиллоу

A crime has occurred in a closed school for girls! On a wonderful May day during Sunday lunch, the headmistress and her brother suddenly collapsed. Seven students realize that Mrs. Plackett and Mr. Godding were poisoned, but by whom?! And... if the neighbors find out about it, the school will surely be closed, and the girls will be sent home. Meanwhile, visitors are arriving at the school one after another at the most inconvenient times (for example, the admiral in love with the headmistress!). So the girls decided to pretend that nothing happened and hide the crime. Moreover, it turned out that the headmistress's financial situation is very bad. So how was the school being funded?! And who is the killer? Each of the schoolgirls is talented in her own way, and united in their efforts, they take up the investigation.
