Who is committing the murders in the Black Woods?

A knight and a monk on the trail of a medieval conspiracy

Henry of Carinthia reigns over the Kingdom of Bohemia, but no one takes him seriously anymore. The land is torn by unrest, and to make matters worse, someone has begun murdering important representatives of the burgher class whose estates are located in the area known as the Black Forests. Henry's worries are deepened by the fact that the victims are his supporters. The king therefore tasks the commander of the Prague Castle garrison, Knight Blahota of Lítožnice, and his friend, the monk Kryštof from the famous Zbraslav Monastery, with finding the murderers. Could the perpetrators of these crimes be the mysterious crusader knights?
