She had conquered.

Thenceforward Mr.
Blake was careful not to maltreat his wife in Isobel's presence.

He complained to her, however, of the child's conduct, which, he said, was due to her bringing up and encouragement, and Lady Jane in turn, scolded her in her gentle fashion for her "wicked words." Isobel listened, then asked, without attempting to defend herself, "Were not father's words to you wicked also, Mummy?
It was not your fault if James forgot to bring round the dog-cart and made him miss the train to London.

Ought you to be sworn at for that ?" "No, dear, but you see, he is my husband, and husbands can say what they wish to their wives." "Then I will never have a husband; at least, not one like father," Isobel announced with decision.
There the matter ended.

Or rather it did not end, since from that moment Isobel began to reflect much on matrimony and other civilized institutions, as to which at last she formed views that were not common among girls of her generation.
