These crimes occurred in the city of Bronnitsy with a difference of one and a half hundred years... In the old days, a sharp saber took the lives of beautiful lovers - Melania and Makar, a lady and her serf actor... The double murder is being investigated by the peace mediator Alexander Pushkin, the son of the poet, and his friend - landowner Claudius Mamontov. In our time, Savva Psaltyrnikov, a major official who managed to amass a huge fortune, build an estate, purchase real estate abroad and open accounts, died of poison. And he didn’t have time to transfer all this to his son... At the request of the police chief, a secret investigation is being conducted by Ekaterina Petrovskaya, a crime columnist for the press center of the Central Internal Affairs Directorate, and Klavdiy Mamontov, a descendant of that same landowner and full namesake. What motivated the criminals - self-interest, revenge, passion? And is there a connection between modern poisoning and a murder a century and a half ago?..
