For some reason she found that Allan Harrington's attitude of absolute detachment made the whole affair seem much easier for her. And when Mrs. Harrington slipped a solitaire diamond into her hand as she went, instead of disliking it she enjoyed its feel on her finger, and the flash of it in the light. She thanked Mrs. Harrington for it with real gratitude. But it made her feel more than ever engaged to marry her mother-in-law.
