Dickens's only serious, uncomic novel, A TALE OF TWO CITIES, is set during the French Revolution and tells a story of unselfish devotion. The beautiful Lucy Manette marries Charles Darnay, the descendant of an aristocratic French family denounced by the revolutionaries, among whom are the memorably evil fanatic Mme. Defarge. When Darnay is arrested and condemned to death, his place is taken at the guillotine by Sidney Carton, who loves Lucy himself and is willing to die to secure her happiness (and who happens to resemble Darnay). His last words--'Tis a far, far better thing that I do than I have ever done...--have become nearly as famous as the novel itself, one of Dickens's most popular works despite its sober subject matter. It is also, with BARNABY RUDGE, one of his only two historical novels.
