About the book: 2007 / That's the trick - the chip was stolen! Straight from home! And it turns out that I, Evlampia Romanova, myself led the robber to the apartment. Well, since I’m guilty, I have to answer, I need to find an old chip from the casino, because for my friend Katya it is a memory of her grandfather. I used just one hair left on a baseball cap, lost by a thief, to determine the name of the girl who wore this cap! But how can this be? Natasha Fomina, it turns out, died two years ago. I don't understand anything! But I have to figure it out! It is necessary to find the stolen property as soon as possible, otherwise Katyusha will be upset. Oh, and Natasha seems to be alive. But how many deaths are there around her! That’s interesting, but what does the trick have to do with it??..
