Ten years after a protracted honeymoon, Yuri and Anna return to St. Petersburg. An amazing thing: over the years, Anna has not changed at all, maintaining her beauty and youth. But this is not the only thing that amazes her husband. He receives anonymous messages about his wife's strange behavior. It is also unpleasant for him that Anna plays on the stock exchange. But what frightens him most of all is the figure of Hecate, with whom Anna never leaves. In the hands of private detective Artem Ponomarev is the diary of a serial killer, who ten years ago kept the entire city in fear. Anna's eternal youth, the confession of a maniac, the curse weighing on the family of Yuri Salakhov – all these are different facets of one mystery, the origins of which lie in antiquity, in the ancient cult of Hecate. The one who solves this mystery will become the master of his own destiny. The novel is published in a new edition. Previously, the novel was published under the title “The Gardens of Cassandra. The Ring of Hecate." The book also includes an excerpt from the next novel, "The Dance of the Seven Veils."
