He painted on for some little time in silence, and Philip, complying with his request that nothing more should be said about it, answered his next question, some common topic, and himself introduced another. But all the time his thoughts were busy enough on the tabooed subject. For a second time, as at the opera a few nights ago, the vague suspicion crossed his mind that Evelyn was in love with Madge, and had somehow betrayed this to her; but now, as then, he formulated this thought only to give it instant dismissal. That being so, he was morally bound to do Evelyn justice, to accept without either comment or reservation the fact that he really required another sitting from Madge, and to do his utmost, whatever her unwillingness and whatever the cause of it, to make her sit to him again. Both the Philip known to the few intimates and the Philip so much respected by the world at large had a very strong sense of fairness, and the fair thing quite certainly was this. It was impossible to deny an artist another sitting if he felt like this about it; it was doubly impossible to deny it to a friend. Even if the picture had been an order, a commission, it would have been but shabby treatment, now that he knew how Evelyn felt about it, not to do his very utmost to get Madge to give him another sitting; but the picture was not that, it was a present, given too, as he had said, "with his love." He could not really doubt that when it was put to Madge like this, she would see it as he himself did. The task itself of talking to her on the subject, it was distasteful to him, for she had been mysteriously indeed, but unmistakably in earnest, about it a few nights ago at the opera. Whatever the cause (and he consciously turned back from even conjecturing at the cause), she had, so she thought, at any rate, an adequate reason for not wishing to continue the sittings, even when the artist's point of view was presented to her, and he foresaw that he might find himself in an opposition to her that would be painful to both of them. Nor had the change in her, which the world compared to the action of a snail retiring into its shell, escaped him. She had been for the last ten days or so reserved, silent, and apt to be startled. More than once he had asked her if anything was wrong, and the vehemence of her assertion that nothing was wrong had rather surprised him. But here, again, he had to pull himself up, and studiously refrain from conjecturing that Evelyn was in any way connected with any private worry of hers. Besides she had said that nothing was wrong; he was bound to accept that. For this reason he rejected the notion of consulting Lady Ellington about it; that would imply a distrust of the girl herself.
