The result of this revelation of Vi’s was to make the girls watch Amanda and the “Shadow” more carefully than ever before. And if it had not been for just this watchfulness there is no telling what might have happened to Billie Bradley, and through her, to her classmates.
And this was the way it happened.
Luckily for the three North Bend chums, Amanda and her “Shadow” shared the dormitory with them and Rose Belser. And so it was that Billie, coming in unexpectedly one day heard the very end of a sentence spoken in a loud whisper by Amanda. And though it was only the end of the sentence, it told a great deal to Billie, whose suspicions had already been aroused.
“—at ten to-night, in Miss Race’s room,” were the words she caught. The fact that Amanda stopped speaking at sight of her and grew an unsightly brick red, gave Billie further proof that the girl was plotting mischief. Very probably the scapegoat was to be—herself.
She gave no sign that she had heard anything out of the ordinary, but when she had found the book she had come for and was out in the hall once more, her heart was pounding heavily and her face was hot.
Ever since they had come to Three Towers Amanda had done her best to discredit Billie. She had not succeeded so far, but some time she might. Was this the time? thought Billie, a dull rage taking possession of her.
No! She would not let Amanda get the better of her. She would outwit her, now that she had been warned. Then a dreadful thought came to her.
Suppose Amanda, thinking she had given her secret away, postponed her miserable plot, whatever it was, until another time? No wonder Billie answered questions queerly that afternoon, so queerly, in fact, that one teacher asked her if she were ill and would like to be excused!
But Billie did not want to be excused—that would mean more time to herself to think. And so she blundered through the miserable afternoon and her heart jumped with relief when the last gong sounded that meant liberty.
Connie and Laura overtook her in the hall on the way to the dormitory and Laura looked actually anxious.
