For many years, a maniac brutally kills women… There were two of them—twin boys! Thirty years ago they were cruelly separated—someone was rewarded, someone was punished.
For thirty years they lived without knowing each other! One was the guardian of the law, the other— a criminal, a maniac! One disappeared, was gone. The other doesn’t remember who he is. Memory— is it salvation or punishment?
Styx 2. The case of a serial maniac has been sent to the archive, investigator Mukayev has vanished, and under the wreckage of a burned cottage, the body of the owner Ivan Alexandrovich Saransky is found. But is it really his? People interested in an invention by a brilliant chemist doubt it—and doubt that Saransky’s discovery could be lost forever.
They hunt for his diaries, but Saransky’s lover, Olga, has no intention of sharing anything with anyone. She devises a clever plan to confuse everyone, disappear, taking the records with her, and earn a great deal of money from it.
But Olga herself becomes a victim of circumstances—her plans are thrown into chaos by a mysterious murder and the friend investigating it: Ruslan Svistunov, who is investigating Mukayev’s case.
