But Rachel herself did not dislike these little graces, partly because they were not put on to impress an audience, but were an incident of their private life as well; and partly because they stimulated a study to which she had only given herself since their return to England and their establishment at Normanthorpe House. This was her study of the man who was still calmly studying her; she was returning the compliment at last. And of his character she formed by degrees some remote conception; he was Steel by name and steel by nature, as the least observant might discern, and the least witty remark; a grim inscrutability was his dominant note; he was darkly alert, mysteriously vigilant, a measurer of words, a governor of glances; and yet, with all his self-mastery and mastery of others, there were human traits that showed themselves from time to time as the months wore on. Rachel did not recognize among these that studious consideration which she could still appreciate; it seemed rather part of a preconceived method of treating his wife, and the wary eye gleamed through it all. But it has been mentioned that Rachel at one time had a voice, of which high hopes had been formed by inexperienced judges. It was only at Normanthorpe that her second husband became aware of her possession, one afternoon when she fancied that she had the house to herself. So two could play at the game of consistent concealment! He could not complain; it was in the bond, and he never said a word. But he stood outside the window till she was done, for Rachel saw him in a mirror, and for many an afternoon to come he would hover outside the same window at the same time. Why had he married her? Did he care for her, or did he not? What could be the object of that extraordinary step? Rachel was as far from hitting upon a feasible solution of these mysteries as she was from penetrating the deeper one of his own past life. Sometimes she put the like questions to herself; but they were more easily answered. She had been in desperate straits, in reckless despair; even if her second marriage had turned out no better than her first, she could not have been worse off than she was on the night of her acquittal; but she had been very well off ever since. Then there had been the incentive of adventure, the fascination of that very mystery which was a mystery still. And then--yes!--there had been the compelling will of a nature infinitely stronger than her own or any other that she had ever known.
