"I mean to unmask the gay lover at my own time and in my own way; never fear, I shall deal gently with her. You will now take this letter of his and put it in your bag, leaving hers in that curious post-office of yours."
"Yes, Rupert."
"And you will give his letter to her at once when you go in without one word of having met me."
"Y ... yes, Rupert."
"As you are too great a fool to be trusted if you once begin to talk, you will have a headache for the rest of the day and go to bed in a dark room."
"Y ... yes, Rupert."
"You will moreover swear to me, now, that you will not speak of our interview here till I give you leave; say I swear I will not."
"I swear I will not."
"So help me God!"
"Oh, Rupert."
