With a grim and rigid face he strode out of the room. Not one of the three hundred students who listened to his lecture saw any change in his manner and appearance, or could have guessed that the austere gentleman in front of them had found out at last how hard it is to rise above one's humanity. The lecture over, he performed his routine duties in the laboratory, and then drove back to his own house. He did not enter by the front door, but passed through the garden to the folding glass casement which led out of the morning-room. As he approached he heard his wife's voice and O'Brien's in loud and animated talk. He paused among the rose-bushes, uncertain whether to interrupt them or no. Nothing was further from his nature than to play the eavesdropper; but as he stood, still hesitating, words fell upon his ear which struck him rigid and motionless. "You are still my wife, Jinny," said O'Brien; "I forgive you from the bottom of my heart. I love you, and I have never ceased to love you, though you had forgotten me." "No, James, my heart was always in Melbourne. I have always been yours. I thought that it was better for you that I should seem to be dead." "You must choose between us now, Jinny. If you determine to remain here, I shall not open my lips. There shall be no scandal. If, on the other hand, you come with me, it's little I care about the world's opinion. Perhaps I am as much to blame as you are. I thought too much of my work and too little of my wife." The Professor heard the cooing, caressing laugh which he knew so well. "I shall go with you, James," she said. "And the Professor----?" "The poor Professor! But he will not mind much, James; he has no heart." "We must tell him our resolution." "There is no need," said Professor Ainslie Grey, stepping in through the open casement. "I have overheard the latter part of your conversation. I hesitated to interrupt you before you came to a conclusion." O'Brien stretched out his hand and took that of the woman. They stood together with the sunshine on their faces. The Professor paused at the casement with his hands behind his back and his long black shadow fell between them. "You have come to a wise decision," said he. "Go back to Australia together, and let what has passed be blotted out of your lives." "But you--you----" stammered O'Brien. The Professor waved his hand. "Never trouble about me," he said. The woman gave a gasping cry. "What can I do or say?" she wailed. "How could I have foreseen this? I thought my old life was dead. But it has come back again, with all its hopes and its desires. What can I say to you, Ainslie? I have brought shame and disgrace upon a worthy man. I have blasted your life. How you must hate and loathe me! I wish to God that I had never been born!"
