The most unusual adventures usually begin in the most ordinary way. An office of a special task force receives a visit from Veronika Olegovna Kamenyeva, who reports that her husband, Nikolay Petrovich—an successful businessman—has recently died. The cause of Nikolay’s death was said to be cardiac arrest. It’s unclear why a completely healthy man woke up in the morning, sat on the bed—and died! After some time, Max, the younger son, started working in his father’s annex. Sometimes he would stay late and sleep in the late man’s bedroom. That’s where they found him. Dead.
The widow’s friend—fortune-teller and healer—claims that supernatural forces arranged the death of father and son—namely an energy vampire Ipetri. But Tatyana Sergeeva doesn’t believe in ghosts, astral attacks, or magic. She understands: someone killed the Kamenyevs; it’s only a matter of finding out who. But the solution turns out so unbelievable that even Tatyana, used to everything, will be stunned when she realizes where the azure shore of the marsh is located.
