The Beast in Nien

1644. In Nien, a trading town in the Swedish province of Ingria, a series of brutal murders occurs, united by a common hand, the motives of which are hard to imagine. The citizens of Nien are gripped by fear. Who will be the next victim? Who benefits from this devilish bloodshed? The first to fear is merchant Malison, whose family and worker have been murdered by a mysterious killer. Rumors circulate that it is Satan himself who is killing. Malison justifiably fears that he will be the next to fall victim to the murderer and begins to search for the criminal himself.
Specially trained people get involved in the investigation - the burgomaster of justice Gryubbe and the royal bailiff Soderblom. And they discover things they would rather not know, but are now forced to.
