The new novel by the famous St. Petersburg writer Galia Sergeevna Mavlyutova, the author of numerous detective stories and a former law enforcement officer, tells about the search for a serial killer. In a big city, people often disappear. Relatives are unsuccessfully looking for a needle in a haystack, but if there is no corpse, there is no crime. Moreover, there is no statement of crime - no one will look for the missing person. The deceased will be buried in a common grave. For Alina Kuzina, a novice operative from the territorial department, catching and neutralizing a criminal is not just fulfilling her official duty, but also achieving the triumph of justice. The main thing is to believe in yourself, despite the outright ridicule of others. She has no experience, no special skills, she often looks naive and ridiculous, but the girl overcomes all obstacles and finds the killer.
