October 1895 Fearless and charming detective of the St. Petersburg police Rodion Vanzarov and his faithful friend-criminologist Apollo Lebedev again go out together into a noble battle against the gallant crime of the 19th century! They have no listening devices or tracking devices at their disposal, high-speed helicopters will not come to their aid and a spy satellite from space will not intercept the enemy signal... they are served only by their own intelligence and erudition, their physical strength and loyalty to the profession. But sometimes these qualities have crushing force! In the new book “Formula of Crime,” Anton Chizh rethinks Pushkin’s “Little Tragedies” in the detective genre, playing out each plot of the classic in the scenery of St. Petersburg at the end of the 19th century. Just think, Vanzarov is pursuing the Stone Guest! And this is just the beginning...
