One after another, large officials who went into retirement die. The criminals’ method is similar: at a critical moment, the old men don’t receive the necessary medicine at home, and they die. After that, the attackers rob the apartment and vanish. Colonel of the Ministry of Internal Affairs Lev Gurov decides to check the old connections of the victims and interrogate the buyers of stolen goods. But everything is in vain. The investigation is at a loss… It turns out by chance that all the dead men used the services of assistants from the same charitable foundation. Gurov’s shrewdness—and… an extraordinary artistic talent—help him verify this terrifying suspicion.
