Contrast between the old character of dr manette and the New one

Wrongfully imprisoned in France for 18 years, Dr. Manette is brought back from the brink of madness by his adoring daughter, whom he treasures above all else. Though he is eventually freed and makes his home in England with his daughter, where he resumes his medical practice, he is still prone to occasional relapses of a trance-like state, in which he does not remember who he is and can only make shoes. It is the condition in which Lucie found him after his years of imprisonment, and the relapses occur when he is in a state of distress. His unjust imprisonment eventually works in his favor when he is held up as a hero by the revolutionaries, a status that enables him to get his son-in-law, Charles Darnay, freed from prison--but only once. When Darnay is re-imprisoned and the doctor's status cannot help him, Dr. Manette reverts back to his trance-like state.
