Final answer:
The current king of England is not mentioned in The Scarlet Pimpernel, as the story takes place during the French Revolution. The main character, Sir Percy Blakeney, is a heroic character known as the Scarlet Pimpernel.
Step-by-step explanation:
The current king of England during the time period depicted in The Scarlet Pimpernel is not explicitly mentioned in the book. The story takes place during the French Revolution, specifically between 1792 and 1794, and focuses on the activities of a secret society that rescues French aristocrats from the guillotine. The main character, Sir Percy Blakeney, is a wealthy Englishman who disguises himself as a foppish dandy to conceal his true identity as the heroic Scarlet Pimpernel.
