Under the Red Robe by Stanley J. Weyman

Through all, it will have been noticed, Mademoiselle had not spoken to me, nor said one word, good or bad. She had played her part grimly, had taken defeat in silence if with tears, had tried neither prayer nor defence nor apology. And the fact that the fight was now over, and the scene left behind, made no difference in her conduct. She kept her face studiously turned from me, and affected to ignore my presence. I caught my horse feeding by the roadside, a furlong forward, and mounted and fell into place behind the two, as in the morning. And just as we had plodded on then in silence we plodded on now; almost as if nothing had happened; while I wondered at the unfathomable ways of women, and marvelled that she could take part in such an incident and remain unchanged.

Yet, though she strove to hide it, it had made a change in her. Though her mask served her well it could not entirely hide her emotions; and by-and-by I marked that her head drooped, that she rode listlessly, that the lines of her figure were altered. I noticed that she had flung away, or furtively dropped, her riding-whip; and I began to understand that, far from the fight having set me in my former place, to the old hatred of me were now added shame and vexation on her own account; shame that she had so lowered herself, even to save her brother, vexation that defeat had been her only reward.
