It was late when they neared Clara Morton’s home. As they approached quietly, a figure ran from the porch to meet them. It was Mabel.

“Shirley,” she cried, “I was so afraid that something had happened to you. I have been waiting here for more than an hour.”

“Well, something did happen,” said Shirley. “I’ll tell you about it when we get upstairs.”

“Come on, then,” said Mabel, “but be careful. I told Clara you probably wouldn’t be home until in the morning, and no one here must see you in that costume.”

“I would like to have said good-bye to him,” she told herself.
