It was in this mind that he had been making his way back to the station when Miss Bart crossed his path; but though, after his brief word with her, he kept mechanically on his course, he was conscious of a gradual change in his purpose. The change had been produced by the look in her eyes; and in his eagerness to define the nature of that look, he dropped into a seat in the gardens, and sat brooding upon the question. It was natural enough, in all conscience, that she should appear anxious: a young woman placed, in the close intimacy of a yachting-cruise, between a couple on the verge of disaster, could hardly, aside from her concern for her friends, be insensible to the awkwardness of her own position. The worst of it was that, in interpreting Miss Bart’s state of mind, so many alternative readings were possible; and one of these, in Selden’s troubled mind, took the ugly form suggested by Mrs. Fisher. If the girl was afraid, was she afraid for herself or for her friends? And to what degree was her dread of a catastrophe intensified by the sense of being fatally involved in it? The burden of offence lying manifestly with Mrs. Dorset, this conjecture seemed on the face of it gratuitously unkind; but Selden knew that in the most one-sided matrimonial quarrel there are generally counter-charges to be brought, and that they are brought with the greater audacity where the original grievance is so emphatic. Mrs. Fisher had not hesitated to suggest the likelihood of Dorset’s marrying Miss Bart if “anything happened”; and though Mrs. Fisher’s conclusions were notoriously rash, she was shrewd enough in reading the signs from which they were drawn. Dorset had apparently shown marked interest in the girl, and this interest might be used to cruel advantage in his wife’s struggle for rehabilitation. Selden knew that Bertha would fight to the last round of powder: the rashness of her conduct was illogically combined with a cold determination to escape its consequences. She could be as unscrupulous in fighting for herself as she was reckless in courting danger, and whatever came to her hand at such moments was likely to be used as a defensive missile. He did not, as yet, see clearly just what course she was likely to take, but his perplexity increased his apprehension, and with it the sense that, before leaving, he must speak again with Miss Bart. Whatever her share in the situation—and he had always honestly tried to resist judging her by her surroundings—however free she might be from any personal connection with it, she would be better out of the way of a possible crash; and since she had appealed to him for help, it was clearly his business to tell her so.
