She had pointed northward, and Gwynne saw a phantom mountain moving along the level surface of the marsh with the quiet plodding motion of a ship under full sail in a light breeze. The curious combination of images fascinated him, and he watched the stealthy silent progress of this night visitor from the tule lands of the north, that looked as if it might have obliterated the world. As he jumped down into the boat he saw before him, on three sides of him, the sparkling night. Then as Isabel laid her hands on his shoulders and he lifted her down, the fog swept over them, and there was nothing to do but sit and watch the glow of pipe and cigarette; even their own outlines were barely visible. "I fancy it will go home when the moon rises," said Isabel, with a little shiver. "Are you cold?" she asked, solicitously. "No," replied a tart voice. "Why didn't you let me ask that? You are not my mother. We can make tea at intervals. How long do you suppose the tide has been out?" "About two hours." "I am quite comfortable and have never resented any adventure. And this is the appropriate time and place for a certain story. As I remarked before I shall not know you until I have heard it. Pasts are dead walls." "It is not necessary that you should know me." "I think otherwise. You are my one friend among eighty millions of aliens, or ought to be. I shall continue to feel a superior sort of acquaintance until you have taken me into your confidence." There was a movement of the fog that he inferred was a shrug. "Very well," she replied, without a break in her cool even voice. "I suppose I shall enjoy talking about myself. It is not often I have had the opportunity to indulge in a monologue in my family, and you certainly are at my mercy. If you attempt to flee you will be mired like the boat, and I could not pull you out." He had never felt the least curiosity about the past history or the inner life of a mortal before, and in normal circumstances Isabel's would not have appealed to him. But her instrumentality in changing the whole current of his life had alarmed his masculinity into a resolve to demonstrate his superiority if it came to a contest of wills; given birth to a subtle assumption of proprietorship, indifferent in material things, but pressing towards the guarded chambers of the spirit. Isabel, vaguely uneasy earlier in the day, began to appreciate the advance of an outer and powerful force upon her precious freedom, and resented it. And while she made up her mind that if it came to a silent contest of wills, hers at least should not be conquered, she reflected that the deeper intimacy, certain to ensue if she gave him her confidence, would insure her a firmer and subtler hold upon his destinies.
