A bowl of poison for the king

The audiobook A Goblet for the King, by author Jan Bauer, read by Petr Štěpán, directed by Ondřej Černý. Magistrate Jakub Protiva and Friar Blasius #3 At a supper hosted by King Wenceslas IV, Duke Frederick of Bavaria is poisoned. The king's chamberlain, Jindřich Škopek of Dubá, has no doubt that the goblet of poisoned wine was originally intended for the monarch himself. But who wanted to poison him and why? These are the questions that New Town magistrate Jakub Protiva of Protivec and the Franciscan friar Blasius must answer. Their successful resolutions of the cases of the Prague Ripper and the Horse Market Vampire make them the perfect choice for this task. But will they succeed this time? The threads of the conspiracy against the king are very tangled indeed, but both honourable men are determined to track down the poisoner at any cost.
