But through or below the grimness was a terrible pity. Philip's heart was very tender for the man whose inexplicable conduct was yet filling him with indignation past words. Arthur was so changed--the last week or two had done the work of years--all the youthfulness, the almost boyish brightness, which had been one of his charms, was gone, dead. He was pale with a strange indescribable pallor, that told of days, and worse still, of nights of agony; the lines of his face were hardened; the lips spoke of unalterable determination. Only once had Philip seen him look thus, and then it was but in expression--the likeness and the contrast struck him curiously. The other time it had been resolution temporarily hardening a youthful face; now--what did it remind him of? A monk who had gone through a life-time of spiritual struggle alone, unaided by human sympathy? A martyr--no, there was no enthusiasm. It was all dull, dead anguish of unalterable resolve. There was silence for a moment. Keir was choking down an uncomfortable something in his throat, and bracing himself to the inquisitorial torture before him to perform. "Well," said Arthur, at last. And Philip looked up at him again. How queer his eyes were--they used to be so deeply blue. Daisy had often laughed at his changeable eyes, as she called them--blue in the daytime, almost black at night, but always lustrous and liquid. Now, they were glassy, almost filmy. What was it? A sudden thought struck Philip. "Arthur!" he exclaimed, "Arthur, old fellow, are you going blind? Is that the mystery? If it is that, good Lord, how little you know her, if you think that----" Arthur's pale lips grew visibly paler. He had been unprepared for attack in this direction, and for the moment he quailed before it. "No," he whispered hoarsely, "it is not that. Would to God it were!" But almost instantly he had mastered himself, and from that moment throughout the interview not even the mention of Daisy's name had power to stir him. And Philip, annoyed with his own impulsiveness, stiffened again. "You are determined not to reveal your secret," he began, "but I want to come to an understanding with you on one point. If I guess it, if I put my finger on it, will you give me the satisfaction of owning that I have done so." Lingard hesitated. "Yes," he said, "I will do so on one condition--your word of honour, your oath, never to tell it to any human being." "Not to--her--Daisy?" "Least of all." Philip groaned. This did not look very promising for the meeting with Daisy, which at the bottom of his heart he believed in as his last--his trump card. Still, he had gained something.
