The Curse of the Grezetsky House

After the conspiracy in Obolotsk is uncovered, Ariadne's abilities gain more and more respect, while Viktor Ostrovou is nominated for an award. At the same time, the situation in the empire continues to escalate, threatening not only war with Dekabria but also the overthrow of the Empress herself. Against this backdrop, a new case concerning the disappearance of one of the sons of a famous lineage, a debaucher and dandy, seems trivial to Viktor. However, it soon turns out that the gloomy estate of the Grezetskys in Iskroretsk holds far more bloody secrets. Will Ariadne manage to identify the criminal and save Viktor from the curse of the Grezetsky family?
