"If I could do that, simpleton, where would the danger be? Annihilated in a moment. Ever since I have known Mason, I have only had to say to him 'Do that,' and the thing has been done. But I cannot give him orders in this case: I cannot say 'Beware of harming me, Richard;' for it is imperative that I should keep him ignorant that harm to me is possible. Now you look puzzled; and I will puzzle you further. You are my little friend, are you not?"

     "I like to serve you, sir, and to obey you in all that is right."

     "Precisely: I see you do. I see genuine contentment in your gait and mien, your eye and face, when you are helping me and pleasing me--working for me, and with me, in, as you characteristically say, 'all that is right:' for if I bid you do what you thought wrong, there would be no light-footed running, no neat-handed alacrity, no lively glance and animated complexion. My friend would then turn to me, quiet and pale, and would say, 'No, sir; that is impossible: I cannot do it, because it is wrong;' and would become immutable as a fixed star. Well, you too have power over me, and may injure me: yet I dare not show you where I am vulnerable, lest, faithful and friendly as you are, you should transfix me at once."
