What has arrived at Tellson’s just today? How does Mr. Lorry describe the people who brought this thing/person? What does this mean? (Book 2 Chapters 21-24)

A letter arrives. Darnay overhears another Tellson's clerk asking Mr. Lorry if he has found the man to whom to give a letter addressed to the Marquis St. Evermonde. The address is shown around, and the other French noblemen admit that they don't know him personally but do know that he supported the revolution and parceled out his land among his peasants. Darnay claims to know the man and promises to deliver the letter to him. I don't recall Mr. Lorry comenting about who delivered it but it might be in the text.
