About the book: 2020 / Why was Arina so unpleasant about the main character of the talk show, of which she became a participant against her will? What is this: ordinary human antipathy or a professional instinct that suggests that the death of little Vitya Kashcheev is a mystery that has not yet been solved, despite all its obviousness? The same as the death of a businessman who fell from his penthouse, because the widow’s obvious guilt is shattered by the unconditionality of her alibi, discovered by Arina while studying the materials of the late opera Shubin, who never completed his hunt for the elusive - or completely non-existent? - killer.
