Quote context

[...]

- I have been seized and brought to Paris. The crime for which I am to lose my life is, they tell me, treason against the majesty of the people, in that I have acted against them for an emigrant. You are that emigrant.

- It is in vain that I tell them that even before the confiscation of emigrant property, according to your commands, I had collected no rent and forced no taxes.

- Their only answer is that I have acted for an emigrant. Where is that emigrant?

- I beg you, Monsieur, heretofore the Marquis, to come to my rescue and release me. I pray you, be true to me, your poor servant.

- Yes, Darnay.

- I have the answer to that letter.

- So soon?

- It is to a prisoner in the La Force Prison in Paris.

- And what is the message?

- Simply that he has received the letter and will come.

- Three days later, a few leagues out of Calais, on the Paris road, Charles Darnay was arrested.

- Citizen, I beg you to observe that I came here of my own free will, in answer to that written appeal that lies before you. Is that not my right?

- Right? Emigrants have no rights.

- You're consigned, Evrémonde, to the Prison of La Conciergerie.
