Story : General Stoyanov, a teacher at the MVD Academy, orders the murder of a certain Nurbagantov, who works in one large bank. From the conversation Stoyanov with a member of his secret organization it turns out that Nurbagantov - a man with a criminal background - was specifically introduced into the bank as an employee, but he was identified by the bank's security chief Vavilov, and therefore a criminal, and Vavilov should be removed.
