Masha Serova gets a job at a law firm as an assistant to one of Moscow’s best attorneys, Ogryov German Valeryevich. And already on the very first day, Ogryov signs a contract with a client—Natalya Yuryevna Skulskaya—on investigating the murder of her beloved aunt, Yalina Skulskaya. To investigate, Ogryov and Masha travel to the Skulskiy house in the Smolensk region. In the house, potential heirs gather to read out the will—and that very evening, one of the heirs is murdered. Is the second murder connected to the first one, to the inheritance, or to some terrible secret of the family? And the secret is definitely there. That’s what Masha tries to figure out together with German.
