The first of two prequels to The Scarlet Pimpernel, The Laughing Cavalier is set in Holland in 1623. It tells the story of Percy Blake, a foreign adventurer and ancestor of the Scarlet Pimpernel who goes by the name Diogenes. Unlike The Scarlet Pimpernel, Diogenes has not yet established himself as a man of sterling character or irreproachable moral integrity. Some of the fun of The Laughing Cavalier is that one is uncertain whether he will wind up in jail or on the scaffold, and whether he just might deserve such a fate.
