The case of the divorced brothers

The year is 898 and the Moravian Kingdom has to fight for its existence after the death of King Svatopluk. The Franks attack from the west, the Hungarians from the east. Nevertheless, Moses II. manages to build on the legacy of the great royal father and maintain his rule. Unfortunately, an unexpected blow comes from his closest relative, his younger brother Svatopluk. Moreover, Nerad, the deputy of Branislav, the commander of Mojmir's guards, is murdered. It seems that Nerad must have died because he discovered something very serious.
Slavomir and Erik take over the investigation...
