The trial turns out well and Darnay is declared free to leave. Everyone prepares to celebrate, but later that night Darnay is retaken by the revolutionaries. Darnay is to have another trial the next day. The next day, the court states that Darnay had been arrested because of evidence written by Dr. Manette. This evidence was Dr. Manette's journal from his imprisonment. In this letter, Dr. Manette told of how he had angered a powerful noble family by telling someone of their secret. In attempts to keep their secret, the family had killed an entire family of peasants except one daughter at the time the journal was written. In the end, Manette curses this noble family by name, Evrémonde; Charles Darnay's family.
This was the only evidence needed for the jury to condemn Darnay to death. The entire family was devastated. They were going to stay in France until Darnay had died, but Carton (who had arrived a few days earlier) told them to prepare to leave because they were in danger of being arrested as well. He also told them to wait to leave until he had arrived. The day of Darnay's execution, Sydney switches places with Darnay. Darnay escapes while Sydney is killed by the guillotine.
This book has an extremely complex element of foreshadowing that the reader cannot discern until finishing the book. There were numerous sections in which Carton prepares for his death that many would not pick up on. When Mr. Lorry and Carton were speaking in this example, Mr. Lorry was talking about Darnay's death, while Carton was talking about his own. "'I heard the fall of the axe in that sound...' (Mr Lorry) '...don't grieve. I encouraged Doctor Manette in this idea because I felt that it might one day be consolatory to her. Otherwise, she might think 'his life was wantonly thrown away or wasted,' and that might trouble her,'(Carton)" (Dickens 234). In that quote, you can see that Carton is talking about his own death while hiding it from the others so that they will not stop him.
This sacrifice for Lucie brings up one question, who loves Lucie more, Darnay or Carton? Darnay was willing to let Lucie stay with her father and has married her and had two children with her. On the other hand, Carton was willing to die for Lucie and her family and gave her up to Darnay so that Lucie could have a happy life.
Carton's sacrifice rises him up to a Christ like figure at the end of the book and shows that redemption is possible from one's past. Like Christ, Carton died so that others could live.
