Mary Lee was so used to leaving such matters to her elder sister that she didn't at once think of protesting. Moreover she was not quite so unselfish as Nan; she did love her morning nap and was not ready to give up an evening's fun with the Hoyts. But at last she said, a little reluctantly: "Couldn't I write the letter, Nan?"

"No, thanks, I reckon I'd better do it," said Nan lightly, and Mary Lee felt relieved not only that she had made the offer but that it had not been accepted.

But after all, Nan did not have to write the letter that evening, for Dr. Paul came in early. He generally stopped for a few minutes every day to see that all was right with his wards, as he called the girls. Jo had come home late, when the others were already seated at the supper table. She gave Mary Lee a top-loftical glance but carried on a conversation principally with Juliet and Maurice.

"She doesn't like it because I wouldn't stay with her and meet that creature," Mary Lee whispered to Nan as they left the dining-room.

"I'm glad you had the good sense not to," said Nan. "Did he come home with her?"

"I suppose so, though I don't know any more about it than you do."

Jo had not tarried with the girls, but had gone directly to the Hoyts' room, to which Mary Lee declared her intention of going also.

"That letter has got to be written, I plainly see," said Nan.

She was about to settle herself to her task, the others having congregated around Mrs. Hoyt, when Dr. Paul came in. Nan greeted him in a preoccupied way.
