Everything will end on Friday

There are different types of detectives: police, lone sleuths, amateurs. But THE BEST DETECTIVES come from a group of friends and classmates. In three seventh grades, a year-end math exam is scheduled, and a prize has been announced: the class that receives the highest grades will go to the sea in Bulgaria! But suddenly, something strange starts happening to the honor students, who are now everyone's hope: Karina seems to accidentally break her arm, a table with teapots falls on Ira in the cafeteria, and a cabinet falls on Mitrofanov in class. It’s not far from a crime... It seems someone has decided to get rid of all those who study well? The detectives from 7“A” take on the case. For middle and high school students.
