The famous actor Andrei Gruzintsev was murdered—in his own mansion, at his own anniversary celebration, surrounded by family and numerous guests. A vintage signet ring disappeared from his finger. And only one guest at the party—the poet Bogoyavlensky—knows how famous and precious this ring is, once belonging to Pushkin himself. But Bogoyavlensky is detained on suspicion of murder. And not without reason—he intended to steal the ring. Will he be able to clear his name, find the murderer on his own, and get the magical ring that the best Russian poets passed to one another?
