Alexandra Korzukhina, artist, restorer and antiques dealer, receives a new order. She is entrusted with accompanying the auction, which will feature a unique collection of products made from amber, copal, corals and rare plastics. The collection is being sold by Olga Iskhakova, the daughter of a famous Moscow scientist who was killed fifteen years ago. The cause of his mysterious death was a Turkish rosary made of Ottoman Bakelite, with cricket-shaped beads, the highlight of the current auction. Olga expects to pay off her huge debts after selling them...But it turns out that rosaries with crickets can kill even now.
