Summer, a cruise liner, a girl. What else do you need for happiness? But for Yevgeniya Babushka, it’s not time for fun. Well-planned events to identify a spy threaten to end in total failure. The cruise ship “Agatha Christie” seems to live its own life, confusing the plans of the guests—and in particular, Zhenya.
On top of that, resolving the situation is hindered by a secret that has been dragging on for centuries. The dagger of Peter the Great, which Savva Morozov so thoughtfully gave to Maria Andreeva—the woman who captured his heart forever—has surfaced from the depths of history and has begun to write a new, bloody chronicle.
Summer, a cruise liner, a man. “This is what matters in life,” Aurora decides—and doesn’t believe herself, because she’s already made so many mistakes. And it’s the horror of everything that’s happening during this weekend cruise that will tell the girl that in reality, this is the only thing that truly matters. Summer, a cruise liner, and a big love capable of anything.
