“And what does this profession bring you, monsieur?”

“Knowledge.”

“It is curious.”

“Very curious.”

“No irony, monseigneur, towards an old and faithful servant, who comes at this hour and in this state to do you a service. If I sat down, on my honor, it was because I could not stand.”

“A service! to do me a service?”

“Yes.”
