Milly meantime guessed nothing of his dissatisfaction. She adored her husband more every day, and her happiness would have been perfect had it not been for the haunting horror of the possible "change" which might be lurking for her round the corner of any night--that "change," which other people might call what they liked, but which meant for her the robbery of her life, her young happy life with Ian. He had taken her twice to Norton-Smith before the great man went for his holiday. Norton-Smith had pronounced it a peculiar but not unprecedented case of collapse of memory, caused by overwork; and had spent most of the consultation time in condemning the higher education of women. Time, rest, and the fulfilment of woman's proper function of maternity would, he affirmed, bring all right, since there was no sign of disease in Mrs. Stewart, who appeared to him, on the contrary, a perfectly healthy young woman. When Ian, alone with him, began tentatively to bring to the doctor's notice the changes in character and intelligence that had accompanied the losses of memory, he found his remarks set aside like the chatter of a foolish child. If maternity would indeed exorcise the Invader, Milly had lost no time in beginning the exorcism. And she did believe that somehow it would; not because the doctor said so, but because she could not believe God would let a child's mother be changed in that way, at any rate while she was bearing it. To do so would be to make it more motherless than any little living thing on earth. Milly had always been quietly but deeply religious, and she struggled hard against the feeling of peculiar injustice in this strange affliction that had been sent to her. She prayed earnestly to God every night to help and protect her and her child, and the period of six or seven months, at which the "change" had come before, passed without a sign of it. In April a little boy was born. They called him Antonio, after a learned Italian, a friend and teacher of Ian's. The advent of the child did something to explain the comparative seclusion into which Mrs. Stewart had retired, and the curious dulling of that brilliant personality of hers. The Master of Durham was among the few of Mrs. Stewart's admirers who declined to recognize the change in her. He had been attracted by the girl Milly Flaxman, by her gentle, shy manners and pretty face, combined with her reputation for scholarship; the brilliant Invader had continued to attract him in another way. The difference between the two, if faced, would have been disagreeably mysterious. He preferred to say and think that there was none; Mrs. Stewart was probably not very well.
