Oldřich of Chlum solves the murders at Valdek Castle
The popular author of historical books and detective stories from the Bohemian Middle Ages brings Oldřich of Chlum with his assistants, the squire Ota and the commander Diviš, to the stage again. This time he is solving the case of the death of Mrs Sibyl, a cousin of the noble and influential Oldřich Zajíc, at his castle in Valdek. Before they can find out whether Sibyl's death was murder or an accident, another murder occurs. There are many suspects, because there is a family festival in the castle. There are many questions that Oldřich of Chlum asks himself. But why does it seem to him that the key to the solution is a tapestry depicting a garden with beautiful flowers, among which stand out lilies, only one of which is black?
