Hawtrey's Deputy by Harold Bindloss

Next morning, the mail-carrier, who drove up to the homestead half-frozen and white all over out of a haze of falling snow, brought Agatha a note from Gregory. It was brief, and she read it with a smile of half-amused contempt, though she admitted that, considering everything, he had handled the somewhat embarrassing situation gracefully. This, however, was only what she had expected of him, and she recognised that it was equally characteristic of the man that he had written releasing her from her engagement instead of coming himself. Gregory, as she realised now, had always taken the easiest way, and it was evident that he had not even the courage to face her. She quietly dropped his note -- it did not seem worth while to fling it -- into the stove.

She could forgive him for choosing Sally. Though she was very human in most respects, that scarcely troubled her, but she could not forgive him for persisting in his claim to her while he was philandering -- and this seemed the most fitting term -- with her rival. Had he only been honest, she would not have let Wyllard go away without some assurance of her regard which would have cheered him on his perilous journey, and it was clear to her that he might never come back again. Her face grew hard when she thought of it, and she had thought of it of late very frequently. For that, at least, she felt she almost hated Gregory.
