The most unusual adventures, as a rule, begin in the most ordinary way. Veronica Olegovna Kameneva came to the office of the special team and said that her husband Nikolai Petrovich, a successful businessman, had recently died. The cause of Nikolai's death was stated to be cardiac arrest. It is unclear why a completely healthy man woke up in the morning, sat up in bed and died! Some time passed, and the youngest son Max began to work in his father’s outbuilding. Sometimes he stayed up late and spent the night in the deceased’s bedroom. That's where they found him. Dead. The widow’s friend, a fortune teller and healer, claims that the death of the father and son was caused by otherworldly forces, namely the energy vampire Aipetri. But Tatyana Sergeeva does not believe in ghosts, astral impacts, or magic. She understands: someone killed the Kamenevs, she just needs to find out who exactly. But the solution will turn out to be so incredible that even Tatyana, who is accustomed to everything, will be stunned when she realizes where the Cote d'Azur of the swamp is located.
