A broken little mirror on a man’s chest, an earring torn from the ear—this is the killer’s peculiar “calling card.” Who killed these two respectable women—a maniac obsessed with gloomy legends of the Vyazemsky family, or his sophisticated imitator? All versions inevitably lead to a dead end. A businessman whose beginnings in connection with these crimes are now under threat decided to seek the help of a private detective. That’s how Anastasia Kamenskaya ended up in the provincial town of Tomilino. Yes—retired police colonel Kamenskaya now works at a private detective agency, and this investigation is her debut in this field. Now, behind her, there is no powerful and influential department—and that is somehow unusual. But Настя still needs to use her ability to talk and listen, systematize facts, and instinctively—this is the pinnacle of her “detective talent”—choose the correct direction of the investigation. In short, she must open all the doors that lie in her path. Because behind one of them there is the truth. And truth isn’t subject to any changes.
