1. How was Charles Darney acquitted in his first trial in London?
The sixth witness gave evidence against Darnay when he said that he saw Darnay in a hotel in a town where there were soldiers.
However Darnay was saved by the help of Sydney Carton. Carton drew the attention of Stryver to the similarity between him and Darnay. Then Stryver disproved the evidence of the sixth witness who could not identify the man he saw.
