A savage desire to grasp her by the throat and hurl her into the waters beyond the break came over him with irresistible power. Then came the pitiable collapse which conquered the murderous impulses and left him weak and broken for the moment. With a sob he turned and leaned upon the wall, his back to her, his face buried in his tense arms--crushed, despised, dishonoured! Kill her? The horror of it swept his brain clear for an instant. Kill his pretty Frances? Kill Jane's mother? How could he think of it? It was a long time before the wretched man knew that she was standing close behind him and was speaking to him. The sound of her voice came through the noise of his pounding heart as if it were far away and gentle. But what was it that she was saying? Her voice was angry, suppressed, condemning. "You may take it or refuse it, just as you please," were the first words his turbulent senses distinguished. "I can pay no more than that for your silence. The other is impossible. I will not discuss it again with you." She paused as if waiting for him to respond. "To-night I shall tell my husband everything--the whole story. I cannot endure the suspense any longer. I will not live in fear of you another hour. My only reason for coming out here to-night is to plead with you to spare your son and Jane. I am not asking anything for myself. It would break Jane's heart if Graydon should refuse to marry her. You must have a heart somewhere in that--" But the words became jumbled in the ears of her listener. From time to time his mind grasped such sentences as these, paralysing in their bitterness: "I have the letters of adoption.... David will not believe what you say.... He loves me and he loves Jane.... I am willing to pay all that I have to keep it from Graydon and Jane.... But I intend to tell my husband. I will not deceive him any longer.... He will understand even though he should hate me for it. He will love Jane although she is not his own child." David Cable seemed frozen to the spot. His brain was clearing; he was grasping the full importance of every sentence that rushed from her impassioned lips. The last appalling words fell like the blow of a club in the hands of a powerful man. He was dazed, stunned, senseless. It seemed to him that his breath had ceased to come and that his whole body had turned to stone. His wide staring eyes saw nothing ahead of him. "Well, what have you to say?" she was demanding. "Why have you asked me to come out here? You have my final answer. What have you to say? Are you going to tell Graydon that Jane is not our child? I must know." "Not our child?" came from the palsied lips of David Cable, so low and lifeless that the sound was lost in the swish of the water below. The intermittent red signal in the lighthouse far out in the lake blinked back at him, but to him it was a steady, vivid glare.
