"The Laughing Cavalier" revolves around Percy Blake, a foreign adventurer and ancestor of the famous Scarlet Pimpernel. In March 1623, the Dutch nobleman Willem, Lord of Stoutenburg, is on the run. His father, the statesman Johan was falsely accused of treason and sent to the gallows by the Stadtholder, Prince of Orange. Willem's brother Reinier has since been arrested and executed for plotting to kill the Prince. Stoutenburg is now a fugitive and determined to get his revenge.
