Pentagram. Nesboe Yu

In a calm and sleepy summer Oslo, a murder was committed, daring and defiant. The culprit left the police not only a tool of crime, but also a small diamond in the form of a five -pointed star, hiding him under the century of the deceased. Soon, the Norwegian capital is amazed at a series of mysterious events, mystically connected with the number five: five rays of a star and a mutilated palm are persistently resembled about it. Every fifth day, the police find a new victim of a mysterious criminal who every time manages to slip unnoticed.
