Sovsem ne zhenskoe ubiistvo - Stivens Robin

In the new school year, no one will call Daisy Wells and Hazel Wong a minnow - yet they are now in the eighth grade of deepdin girls' school. In honor of this great event, friends decided to forget their stupid children's fun and founded a secret detective agency. The first case - about the missing tape of a classmate Lavinia - was so simple that it should not be mentioned (yes, it is not worth it, but there were no others). And would share the sad fate of the previously closed Society of Pacifists and Spiritual Society if Hazel had not accidentally found the corpse of Natural History teacher Miss Bell in the gym. And the friends decide to find the killer before the police. Because it's their business.
