There is always twilight on the outskirts. Kasyan Yu.

In a small apartment of a regular five -story building, the body of a young woman with numerous knife wounds was found. On the victim’s face, a long incision blows, creating a terrifying likeness of a terrible smile, and the lips are coldly stitched with black threads. Who could commit such a nightmare crime, going out of the face of even the most perverted fantasy?

Trying to unravel the plan of this cruel atrocity, the arrogant and conceited detective Alain Rasmus, obsessively wanders in the maze of mysteries and secrets surrounding not only this murder, but also a similar event that occurred ten years ago. Catching a distraught maniac is half the case: to find out his motive is much more difficult. What if the victims... deserved their punishment?
