Pensioners in Moscow have become detectives: they follow their husbands and children in search of food in the capital, elderly women have begun to offer private investigation services. Advertisements stating that they are willing to discreetly spy on a husband, wife or child are posted right in the elevators of residential buildings. Their main trump card is complete invisibility to others. The pensioner on the bench at the entrance does not arouse any suspicion, but she sees everything that happens around her. At the same time, "Russian Miss Marples" charge a nominal fee for work, and sometimes even agree only to food, assuring clients that they work no worse than professionals.
