“I’ll play a Christmas carol, just to celebrate!” she decided, and struck the opening chords of “O come all ye faithful.”

She stopped abruptly. “What a terrible rattle!” she exclaimed. “These people must throw their tin cans into the piano when they finish with them!”

She stood up and examined the top with her candle. Lifting up the hinged half, she peered down into the space beneath. Instantly she perceived a gray flannel bag hanging on the end of one of the keys as if someone had deliberately hidden it there.

She snatched it off excitedly, delighted to find that it was heavy. No doubt it contained something metallic, which had been the cause of the jangling of the piano keys. With trembling fingers she pulled open the string and dumped the contents of the bag upon a chair.

Diamond rings, bracelets, earrings, watches, and gold necklaces dropped out before her astonished eyes. A fabulous treasure, such as one reads about in fairy tales or sometimes dreams of finding! Color came to Mary Louise’s cheeks, and her heart raced wildly as she examined the articles one by one to make sure that they were genuine.

Mrs. Weinberger’s old-fashioned timepiece ornamented with diamonds was there—and Mary Louise’s own dainty little wrist watch, engraved with her name in the back of it. Oh, what a joy it was to have it again! She clasped it affectionately about her wrist.

Leaving the jewelry on the chair, she peered into the piano again to see what else she could find. She was rewarded with another discovery. Down in a corner, in a remote spot, she saw a small package wrapped in brown paper. She encountered some difficulty in prying it loose, but at last she had it free. Stripped of its brown-paper wrapping, she found that she held a fat wad of bills in her hand!

“Mrs. Macgregor’s money!” she thought immediately. “And Miss Granger’s—and my own five dollars!”

How wonderful it all was! To be able to return the possessions to the rightful owners at Stoddard House! To have proof enough now to convict Mrs. Ferguson and her band of thieves! To collect her salary from Mrs. Hilliard and go home—in time for Max’s senior dance!

If—only—she could get out of this house!
