Then Betty began making tea on her alcohol lamp and talking of other things; only Polly could see that her mind was not in the least upon what she was saying, but that she was thinking of something else every possible second.

Whether to go or to stay with her friend was Polly's present indecision. However, she and Molly remained until Mrs. Ashton had returned from her drive and Betty went into her mother's room to assist in taking off her wraps.

CHAPTER XXI

BETTY FINDS OUT

It was Monday afternoon and the March weather held an alluring suggestion of spring.

Running along the street with her red coat scarcely fastened and her hat at a totally wrong angle upon her head, Polly O'Neill showed no concern for exterior conditions.

Finding the Ashton front door unlocked she entered without stopping to ring the bell, and made straight, not for Betty's, but for Mrs. Ashton's bedroom. She found her lying upon the bed, though at her visitor's entrance she sat up, appearing quite ill.

"O Mrs. Ashton, why didn't Betty come to school today? Where is she? Has anything happened? I was dreadfully worried when I found she was not at any of her classes, and then when I asked Miss McMurtry whether anything was the matter, she was so queer and mysterious. And when I said I was going to leave school and come here at once, she said that I had better not, that Betty had specially asked to be alone and that even you had not seen her this morning. Donna behaved just as though she knew something about my beloved Betty that I don't. And it is not fair. I am sure Betty would wish me to know. Where is she?"

"Sit down, Polly," Mrs. Ashton returned, getting up from the bed and taking a seat opposite. "I don't know where Betty is just now and I am very uneasy and very unhappy about her. The poor child has had so many things happen in the past year, after being spoiled in every possible way up till then. She was in her own room most of the morning, but about two hours ago sent word to me that she was going out and that I was not to be alarmed if she did not return for some little time. I might as well tell you our secret, dear. I suppose there is no way now to keep people from knowing it eventually and perhaps we have been unkind and unwise in concealing it from Betty so long. I wonder if you have ever dreamed that Betty is Esther Crippen's sister?"
