Someone is asking for forgiveness

On the deserted shore of Baikal, a fisherman dead from a heart attack is found. The situation seems obvious — death from natural causes, but Felix Verbina has doubts and takes on the investigation of a case that does not... exist, to learn about an old expedition to the mysterious Cape Rytomu, all the participants of which are considered dead, and how it is connected to the terrible events in modern Irkutsk. Baikal, an ancient, sacred sea... On its shores, legends intertwine with reality and become part of everyday life, filling life with the inexplicable. Some try to explore the mysteries of Baikal from a scientific perspective, others believe in their mystical essence. Some strive to keep away from the unusual, while for others, turning to the Mystery becomes the last chance for salvation. But everything in the world has a price, and sometimes it turns out to be unreasonably high.
