Clients are not chosen, Polina Kazakova, better known in the city as Miss Robin Hood, had to be convinced of this once again. On the recommendation of a mutual friend, Sergei Bocharov turned to Polina for help. He claimed that many years ago, while a group of climbers were climbing the mountains, his father was killed. He even had, as he believed, documentary evidence of the crime - the recently published novel “White Slopes,” written by one of the expedition members. Now the killer, former investigator Seleznev, lives quietly in retirement. Bocharov very urgently demands that Kazakova punish the villain, and by killing him herself! If he refuses, he threatens the lives of people close to Polina, two of whom are already his hostages!..
