In this short scene, we learn that the master of the castle is looking for someone to act as a double agent for him and his wife. The double agent is none other than Dr. Manette, who has just returned from a trip to Europe. He has come back to the castle because the master is worried that the two of them are not very familiar with the place, and that Doctor Manette has asked him to help them. Dr Manette asks the double agent if he would like to talk to his friend about the matter, and the double-agent says that he would rather do it himself.
