Overview
He is a wealthy gentleman who spends time in both France and England during the time of the story. However, he resents how the lower classes are extorted and kept in extreme poverty by the upper class. Darnay specifically goes against his uncle, Marquis St. Evrèmonde, who has no respect for the people in poverty.
When the revolutionaries are trying to find and kill the Marquis, Darnay realizes that his uncle has been murdered, making him the new Marquis. He is put on trial for treason against the Kingdom of Great Britain, but he is acquitted on a point noticed by Sydney Carton. Carton also falls in love with Darnay's future wife Lucie during the trial. At the end of the final book, Darnay is supposed to be executed, but Carton nobly chooses to take Darnay's place.
