But Isabel had also vague impressions of herself crossing the sea;--_re_crossing, emphatically thought Pierre, as he pondered on the unbidden conceit, that she had probably first unconsciously and smuggledly crossed it hidden beneath her sorrowing mother's heart. But in attempting to draw any inferences, from what he himself had ever heard, for a coinciding proof or elucidation of this assumption of Isabel's actual crossing the sea at so tender an age; here Pierre felt all the inadequateness of both his own and Isabel's united knowledge, to clear up the profound mysteriousness of her early life. To the certainty of this irremovable obscurity he bowed himself, and strove to dismiss it from his mind, as worse than hopeless. So, also, in a good degree, did he endeavor to drive out of him, Isabel's reminiscence of the, to her, unnameable large house, from which she had been finally removed by the pleasant woman in the coach. This episode in her life, above all other things, was most cruelly suggestive to him, as possibly involving his father in the privity to a thing, at which Pierre's inmost soul fainted with amazement and abhorrence. Here the helplessness of all further light, and the eternal impossibility of logically exonerating his dead father, in his own mind, from the liability to this, and many other of the blackest self-insinuated suppositions; all this came over Pierre with a power so infernal and intense, that it could only have proceeded from the unretarded malice of the Evil One himself. But subtilly and wantonly as these conceits stole into him, Pierre as subtilly opposed them; and with the hue-and-cry of his whole indignant soul, pursued them forth again into the wide Tartarean realm from which they had emerged. The more and the more that Pierre now revolved the story of Isabel in his mind, so much the more he amended his original idea, that much of its obscurity would depart upon a second interview. He saw, or seemed to see, that it was not so much Isabel who had by her wild idiosyncrasies mystified the narration of her history, as it was the essential and unavoidable mystery of her history itself, which had invested Isabel with such wonderful enigmas to him.
