After a terrible snowstorm, Colomba Caselli, familiar to readers from the novels Killing Father and Killing an Angel, discovers an autistic teenager named Tommy in her barn, smeared with blood. It turns out that his parents were killed in front of his eyes. And although Colomba retired a year and a half ago, trying to recover from the tragic events in Venice, when she almost died and her friend Dante Torre was kidnapped, the young woman is forced to get involved in the investigation. No one but her can solve the mystery of Tommy, who sometimes behaves exactly like the victims of Father, a child abductor and a serial killer. Colombe also has to find his friend and, together with him, understand who is hiding under the mask of the king of coins, who controls the deadly game. Sandrone Dazieri, a master of psychological thrillers, in the final book of his trilogy builds a castle of mirrors and deceptive moves. The reader, feverishly turning the pages until the stormy and tense finale, discovers that in the text, built on the principle of a nesting doll, more and more new riddles emerge. For the first time in Russian!
