Since error, two mistakes... The case of a broken “bug” (#1), McNIKOL S.

Stephen Nobel is a very shy schoolboy. Oh often comes across awkward situations and speaks out of place. Nevertheless, he tries to control his life, and therefore keeps strict records of all his mistakes. And not only his own... That is why Stephen notes a lot of interesting things. Why do different people travel driving the same car? Why did the police blow his classmate's backpack? Who pierced the school wall? All these are mistakes that someone made. And these are crimes, and Nobel will certainly reveal them!
