A minute or two passed, but no more allusion was made to the news which had so disturbed their hostess's equilibrium. And before there was opportunity for the discussion of any other subject, the sisters, moved by a common instinct, discovered that it was getting late, and that they had already outstayed their time. Mrs Dalrymple could not resist kissing them both affectionately as they said good-bye, but this was the only expression of sympathy on which she ventured. It was already twilight out of doors. Still not so dusk but that Sydney stole timid glances at her sister's face in wistful anxiety as to what there might be there to read. But it seemed all blank: she might have stared at her with open inquiry, Eugenia would have been unconscious of it. She walked along quite quietly, replying mechanically to the little commonplace observations Sydney hazarded from time to time; but for the curious expression, or rather curious absence of expression in her usually changeful, speaking face, her sister would have suspected nothing but that Eugenia was in a more than usually silent mood this evening. As it was, Sydney felt bewildered and uncertain, vaguely apprehensive, yet not satisfied that there was new cause for any increase of her anxiety. "Possibly," thought Sydney, "this definite news may do her good. It may show her what a poor creature he is after all, and may rouse her to shake herself free of the remembrance of him altogether." She hardly understood that to Eugenia such a reaction, healthy and "sensible" though it might be, was impossible. Through all her despair and misery Eugenia clung with instinctive self-regard to her delusion; over and over again she repeated to herself in almost the same words, the poor little formula of faith in her lover which she told herself and really imagined she believed. It was her safeguard at this time, and well for her that she could hold to it; for what to some girls would have been merely a passing though sharp mortification, would to her have been a loss of self-respect extensive enough to have shaken the whole foundations of her character. Very near their own house the sisters were overtaken by Frank Thurston. He walked beside them to the door, but seemed to hesitate about entering. "Aren't you coming in, Frank?" asked Sydney. "It is hardly worth while," he replied, eyeing regretfully his but half consumed cigar. "I have only five minutes to spare. Suppose you walk up and down with me, Sydney, instead of my coming in. It's going to be a beautiful evening." Sydney glanced at Eugenia. "Yes, do, Sydney," said Eugenia. Sydney fancied she could discern in this a longing on her sister's part to be alone, if but for a quarter of an hour. "Very well, then, I will stay out with you for a little, Frank," she agreed, and Eugenia entered the house by herself.
