She thought Sir Percy to be a vain,pompous dandy and could not conceive how she ever married him. Inspite of this she still had feelings of love for him. Sir Percy loved her deeply, though he also hated and detested her for what she did. He was emotionally torn between love and hate though he would have given or done anything for her, save revealing his true identity as The Scarlet Pimpernel. The French authorities sent the accredited agent, Monsieur Chauvlin with the fox-like expression to England to capture the League of The Scarlet Pimpernel and their leader. He approached Marguerite for help because of her past cooperation and friendship. She denied his request with disgust. Through a turn of events he acquired damaging information concerning her brotherArmond, who was involved with the League. She was forced to assist the clever Chauvlin in his evil task with the promise thather brother would be set free from prosecution. At Lord Greenville's Ball she took a scrap of paper from Sir Andrew, a League member of The Scarlet Pimpernel. This paper revealed the meeting time of the League leader in the supper room. She gave the paper to Chauvlin who hid himself in the room and cleverly deduced that Sir Percy was the leader of the League. He formed a plan to capture the Scarlet Pimpernel. After Marguerite realized what a terrible thing she did, she told Sir Percy everything about Chauvlin and her brother. SirPercy assured her he would save Armond and the Comte de Tournay and sailed for France the next day. Next, Marguerite investigated his room and found maps of Paris, a large painting of his mother, a large desk with many papers scattered on it and a ring with the engraving of a scarlet pimpernel on it. Knowing then that the Scarlet Pimpernel was Sir Percy she enlisted the help of Sir Andrew Ffoulkes. Quickly they sailed to Calais to tryto warn Sir Percy that Chauvlin knew his true identity and had laid a trap for him.
