She wanted no quarrel and was confident of her ability to prevent one. If one came, she would have to be arbiter; she would have to take sides, and that must almost certainly mean the loss of one of her friends—either Sidney Barslow or Arthur Lisle. She did not want to lose either, for each had an attraction for her—an attraction not of mere solid friendship such as bound her to Joe Halliday, but an appeal of man to woman. Barslow's boldness, his challenge, his powerful virility drew one side of her nature with a strong magnet; to what was 'second-class' and tawdry in him she was not, by birth or breeding, very sensitive herself. On the other hand she knew that Arthur Lisle was, and admired him because he was. Nay, in a sense she was afraid of him because he was; if she did or said anything in his eyes amiss—if she shewed too much favour to Sidney Barslow, for instance—he might feel about her much as he did about the man himself. She knew all about Barslow, and all about what Barslow felt for and about herself; it was very familiar, one might say inherited, ground. With regard to Arthur Lisle all this was different; he was still, in spite of their apparent intimacy, terra incognita. Though he constantly frequented the house, though from a chance acquaintance of her brother's he had grown into a familiar friend, though they were fast comrades, even though she knew that he admired her, there was so much about him which she vaguely divined to be there, but could not value or analyse—notions, instincts, spots of sensitiveness, to which she remained really a stranger. How strong were they, what was their verdict on her, what their influence on him? Would a tide of admiration or passion sweep them all away? Or would they make such a tide impossible, or, even if it came, dam its course with impalpable insurmountable obstacles? In fine, would he, in spite of any feeling for her that he might have, hold her "out of the question"?
He was the last to leave that night—as he often was, for the solitude of his lodgings had no attraction for him—and she went with him to the door. The stars shone now over Regent's Park, and they lingered a moment in astronomical conversation. Then she gave him her hand, saying:
"I'm so sorry about Monday. But you must tell me all about your party afterwards!"
"I don't suppose there'll be anything to tell. Well, Mildred Quain may be interested, because of her uncle!"
"I shall be interested too—though not because of my uncle," she said with a laugh and a fleet upward glance at him. "I consider I've introduced you to London society, and I take a maternal interest in you, Mr. Lisle."
"Why do you say 'Mr. Lisle' to me? You always say 'Joe' and 'Sidney' to the others."
"So I do. I don't know!"
"Well, then, don't do it," laughed Arthur. "It makes me jealous, you know."
She looked at him for a moment, not now in provocation, rather in thought, perhaps in puzzle. "It needn't do that, anyhow," at last she said.
"Is it then a mark of respect?" he asked banteringly, finding pleasure in the perplexed little frown which persisted on her pretty face.
