Fortunately no one outside the house had known of Genevieve's nonappearance that Christmas Eve, so she was spared any curious questions and interested comments from others of the Happy Hexagons.

The short Christmas vacation sped rapidly. The young people spent much of it on the river, skating, when the ice was good. Genevieve, it is true, was not often seen there. Genevieve was playing nurse these days, and so devotedly attentive to Miss Jane Chick was she, that both the ladies had almost to scold her, in order to make her take needed exercise. Even Harold Day reproached her one morning, when he met her coming from the post-office.

"You don't let any of us see anything of you—not anything," he complained. "And you look as if you were doing penance, or something—you've got such a superior expression!"

Genevieve dimpled into a sudden laugh.

"Maybe I am," she retorted. "Maybe I did something bad so I could do something good; and now I'm trying to do enough good to take out all the taste of the bad."

"Well, what do you mean by that, Miss Mystery?"

She would not tell him. She only shook her head saucily, and ran into the house.

By New Year's Day Miss Jane seemed almost like her old self, and Genevieve was specially happy, for on that night Harold Day gave the first dance of the season; and, with Miss Jane better, and her own heart lighter once more, she could give herself up to full enjoyment of the music, fun, and laughter.

All the Happy Hexagons were there, together with O. B. J. Holmes, Charlie Brown, and many other of the young people, including even Tilly Mack's big brother, Howard, who—though quite twenty-one—was a prime favorite with the Happy Hexagons.

Genevieve was wonderfully happy that evening. Never had the music sounded so entrancing; never had her own feet felt so light. With Harold she "opened the ball," as Tilly airily termed it; then Charlie and O. B. J. had their turn.
