"Later on I apologized to Mark for the reckless things I had said to him, and he played the part of a magnanimous gentleman with his accustomed skill, but, though outwardly we were as before to each other, from that day forward, though his vanity would never let him see it, I was his bitterest enemy. If that had been all, I wonder if I should have killed him? To live on terms of intimate friendship with a man whom you hate is dangerous work for your friend. Because of his belief in me as his admiring and grateful protege and his belief in himself as my benefactor, he was now utterly in my power. I could take my time and choose my opportunity. Perhaps I should not have killed him, but I had sworn to have my revenge--and there he was, poor vain fool, at my mercy. I was in no hurry.

"Two years later I had to reconsider my position, for my revenge was being taken out of my hands. Mark began to drink. Could I have stopped him? I don't think so, but to my immense surprise I found myself trying to. Instinct, perhaps, getting the better of reason; or did I reason it out and tell myself that, if he drank himself to death, I should lose my revenge? Upon my word, I cannot tell you; but, for whatever motive, I did genuinely want to stop it. Drinking is such a beastly thing, anyhow.
