Not quite herself, for she was beautified and transfigured with happiness into a very different Polly Haddon from the one the girls had known.

Miss Walters was summoned and made her come into her own private rooms. Of course the girls went also, and while Mrs. Haddon was stretched luxuriously on a couch in Miss Walters’ sitting-room, Billie told how she had frightened the simpleton into confessing his guilt and restoring the stolen goods.

Billie was so modest about her leading part in the affair that Laura was forced to interrupt occasionally, and, disregarding Billie’s frowns, add a bit of explanation here and there that enabled her audience to visualize the thing just as it had happened.

“We can keep it here for you, in the big school safe,” she suggested, “or we can have it carried over to your house, just as you wish.”

“Oh no, leave it here,” said Polly Haddon quickly. “I will notify that Philadelphia knitting company that the invention has been recovered, and if they still wish to buy it, it probably will not remain here long. Oh, how can I thank you all——” her voice broke, and for a little while all of them felt a bit uncomfortable while Polly Haddon sobbed out her happiness and gratitude.

Here, perched on the bed with Connie and Vi, Laura gave a graphic account of everything just as it had happened to a sympathetic audience of some twenty girls.

She rang Billie’s praises to such an extent that the poor girl tried to hide herself in an inconspicuous corner, only to be dragged forth into the limelight again by a couple of laughing and heartless maidens.

“You get up there where you belong,” cried one of them, shoving Billie up into the center of the bed which was already over-crowded with giggling girls. “Don’t you know that you’re a real, honest-to-goodness heroine?”
