There are only a few characters who are fully developed in A Tale of Two Cities.
1. Therese Defarge who is in the annuals of classic villains. Her irrational hatred and Poe-like obsession with revenge is best exemplified in Book the Third Chapter 12. In this chapter, Jacques Three converses with Madame about the Republic and asks where they will stop. She replies, "At extermination." When her husband makes an appeal for Dr. Manette who has suffered much, suggesting that she goes too far, Mme. Defarge retorts,
Tell the wind and fire where to stop; not me.
2. Mr. Lorry, dressed in brown with a quaint wig upon his head, who represents Tellson's Bank, describes himself as a "businessman." He tells Lucie Manette,
And you will see how truly I spoke of myself just now, in saying I had no feelings, and that relation I hold with my fellow creatures are mere business relations....Feelings! I have no time for them, no chance of them, I pas my whole life, miss, in turning an immense pecuniary Mangle. [Book the First, Chapter 4]
3. C. J. Stryver is the barrister who exploits the talents of the dissipated Sydney Carton. Dickens describes him as "shouldering his way to a large and lucrative practice."
Towards Soho, therefore, Mr. stryver shouldered his way from the Temple, while the bloom of the Long Vaction's infancy was still upon it. Anybody sho had seen him projecting himself into Soho while he was yet on Saint Dunstan's side of Temple Bar, bursting in his full-blown way along the pavement, to the jostlement of all weaker people, might have seen how safe and strong he was. [Book the Second, Chapter 12]
4. Dr. Manette, the doctor who was summoned by the Evremondes and imprisoned for fourteen years, has lost much of himself. When he is introduced to the reader, he is described in this manner,
The faintness of the voice was pitiable and dreadful....It was like the faintness of solitude and disuse. It was like the last feeble echo of a sound made long and long ago. So entirely had it lost the life and resonance of the human voice, that it affected the senses like a once beautiful colour, faded away into a poor weak stain....So expressive it was, of a hopeless and lost creature, that a famished traveller, wearied out by lonely wandering in a wilderness, would have remembered home and friends in such a tone before lying down to die. [Book the First, Chapter 6]
