Kirill never imagined that the girl in glasses named Nastya would become so dear to him— and that, skipping his trip to Dublin, he would end up investigating the death of her grandmother. Nastya doesn’t believe that the grandmother died by dropping a hair dryer into the bathtub. After examining the house, Kirill agrees with her. And now not only Nastya and her relatives, but also Kirill wants to find out: with what money for half a century did the old lady live comfortably—who left behind an inheritance including a diamond necklace worth one hundred thousand dollars, a small house on the shore of the Gulf of Finland, and an ancient library? And who is rummaging around the house in the dark, trying to starve the old lady’s heirs and find the rest of the treasures?
