It certainly was a remarkable evening. But the thing which astonished Peggy even more than the dramatic appearance of Elaine's mysterious sister, was the fact that Mrs. Marshall kissed her good night.

CHAPTER XIX

AMY IS DISILLUSIONED

"Elaine's sister here! Why, I didn't even know she had a sister. Is she nice, Peggy? Has she come here to live? It'll be lovely for Elaine, won't it?"

That was the way Friendly Terrace received the announcement of the third member of the Marshall household. It was surprisingly easy, Peggy found, to evade answering questions as to the date of Grace's arrival, and the reason she had not joined the family earlier. Peggy said with perfect truth that Grace was not very strong and that even now it might be some time before she was able to see Elaine's friends.

But by the end of a fortnight Grace was so far restored to the normal attitude of girlhood toward the world outside that she no longer shrank back from the window if a passer-by chanced to look up, nor gave evidences of collapse when Peggy suggested that one of the girls might come in with her after school.

As a matter of fact Grace made a much more favorable impression on the girls of the Terrace than Elaine had done. There was something in her look of fragile delicacy that was distinctly appealing. Ruth lost her heart to her at once, after the impulsive fashion of school girls. Priscilla, who, ever since her misunderstanding with Peggy, had been on her good behavior, took especial pains to be cordial to the new-comer. It occurred to Peggy one afternoon to wonder how it happened that Amy had not as yet accepted any of their invitations to call and meet Elaine's sister.

"I'm sure you'd like her, Amy. And you're just the one to do her good. Suppose we run in for a few minutes."

"I guess not." Amy's tone was hollow. "I don't feel like meeting strangers."

Peggy cast a sidelong glance in her direction, and made a discovery which temporarily banished from her mind the topic under discussion.
