After receiving a letter from his steward Gabelle, Charles Darnay is drawn to the "loadstone rock," a metaphor for the magnetic pull of fate. Returning to France, Darnay comes to the defense of Gabelle, asserting that the man has drawn no taxes from the peasants who reside on his property. Nonetheless, Darnay is greeted with animosity when he arrives in the town of Beauvais, as "Down with the emigrant!" and "He is a traitor!" is shouted at him. As Darnay continues with an escort, he is stopped at the barrier and sent to prison, LaForce. Then, in Chapter 7 of Book the Third, Darnay goes on trial; he tells the tribunal that he has returned to France of his own volition to save a citizen. Dr. Manette, who has come to France on behalf of his son-in-law has testified for him as has Gabelle and Darnay is acquitted of the charges against him.
However, as fate would have it, Darnay is no more set free than he is rearrested as a prisoner of the Republic. When Doctor Manette demands to know who has denounced Charles Darnay, he receives the reply that he has been accused by Saint Antoine. Finally, one of the men tell the doctor that it was Defarge and Dr. Manette:
"Well! Truly it is against rule. But he is denounced--and gravely--by the Citizen and Citizeness Defarge. And by one other."
Ironically, the "one other" is Dr. Manette, who wrote a letter while incarcerated, deouncing the Evremonde brothers, the father and the uncle of Charles Darnay. the man who raped the sister of Therese Defarge.
