If found guilty of treason, Darnay will suffer a gruesome death, and the testimony of an acquaintance, John Barsad, and a former servant, Roger Cly, seems sure to result in a guilty verdict. Questions from Darnay's attorney, Mr. Stryver, indicate that Cly and Barsad are the real spies, but the turning point in the trial occurs when Sydney Carton, Stryver's assistant, points out that Carton and Darnay look alike enough to be doubles. This revelation throws into doubt a positive identification of Darnay as the person seen passing secrets, and the court acquits Darnay.
After the trial, Darnay, Carton, and Stryver begin spending time at the Manette home, obviously attracted to Lucie's beauty and kind nature. Stryver decides to propose to her, but is dissuaded by Mr. Lorry. Carton confesses his love to Lucie, but does not propose, knowing that his drunken and apathetic way of life is not worthy of her. However, he vows that he would gladly give his life to save a life she loved, and Lucie is moved by his sincerity and devotion. Eventually, it is Darnay whose love Lucie returns, and the two marry with Doctor Manette's uneasy blessing. While the couple is on their honeymoon, the Doctor suffers a nine-day relapse of his mental incapacity and believes he is making shoes in prison again.
Meanwhile, the situation in France grows worse. Signs of unrest become evident when Darnay's cruel and unfeeling uncle, the Marquis St. Evrémonde, is murdered in his bed after running down a child with his carriage in the Paris streets. Although Darnay inherits the title and the estate, he has renounced all ties to his brutal family and works instead in England as a tutor of French language and literature.
