There was a moment of intense stillness. He before whom these two stood knew human nature well. He knew every way in which to work upon a solitary being, a soul alone, in his power; but he knew that before two, awake, alive, on the watch one for the other, these methods were without power, and though his experiences were so great the situation was new. They were in the first absolute devotion of their union, invulnerable, no germ of distrust, no crevice of possible separation. He might kill, but he could not move them. This mysterious agent was not above the artifices of defeat. To separate them was the only device that remained to him. "You are aware," he said, "that here if nowhere else you are absolutely in my power. You have come to me. I have not gone to you. If you wish to sacrifice her life you can do so, but what right have you to do it? How dare you take her from those who love her, and make her your victim? She will be your victim, not mine. There is time yet for her to escape. It is for her to go--Die? why should she die? Are you worth such a sacrifice? Let her go----" "Hold me fast--do not loose me, Walter," cried Oona wildly in his ear. And here his last temptation took him, in the guise of love, and rent him in two. To let _her_ perish, was that possible? Could he hold her though she was his life, and sacrifice hers? Walter could not pause to think; he tore his hand out of hers, which would not be loosed, and thrust her from him. "Oona," he cried, his voice sinking to a whisper, "go! Oona, go! Not to sacrifice you--no, no, I will not. Anything but that. While there is time, go!"
