Where is the diary, Derivolkov?

In the diary of fifth grader Serafim Derivolkov, comments from the teacher regularly appear. But not just "Was fooling around" or "Talked during the lesson," but the most unusual ones. Yes, Serafim often finds himself in different interesting situations, which... constantly causes a strain in the nervous system of the class teacher. The hero, out of principle, eats his vocabulary dictation, drinks compote using shoelaces, sits under the desk with a loaf of bread, calls his friend an eggplant during the lesson, bites a classmate, and hides in the closet after the bell.
Unconventional stories with Serafim happen not only at school. He is the right hand of pensioner Arkadyev (this position required a whole casting). Together with him and high school student Zhenya Makhonov, the hero patrols the surroundings of his home, lies in ambush, and reconciles neighbors. And also - he finds out the circumstances of the appearance of a UFO in the yard and investigates the disappearance of a cake from pharmacist Krol.
Natalia Vishnyakova is a journalist and educator, author of children's and adolescent stories, film scripts, and plays for puppet theater. "Where is the diary, Derivolkov?" wonderfully fits into the series of books by the author already published by the "Five Quarters" publishing house, full of humor and unexpected plot twists. The brightest moments of Serafim's adventures are illustrated by Valeria Sidorova.
