CHAPTER XXI

A PLAN TO CATCH THE THIEF

"That settles it!"

Fred was saying these three words over several times to himself as he stood and stared at the seven little opals. They had appeared rather pretty when he looked at them in Miss Muster's best room, on the occasion of his visit there in company with Bristles. They gave him a shiver now; just because he knew that they had tempted weak Gabe Larkins to commit a terrible wrong.

What had he better do about it?

Fred had, in fact, about made up his mind that there was only one course open to him in case he found the opals. This was to go to Miss Muster at once, and let her know what had come to pass.

She would be glad, for the sake of Bristles and his parents—yes, Fred began to believe the old maid really had a heart of her own, and would herself rejoice over the vindication of her nephew.

But should he take the opals along with him? He decided against this as unwise. To fully prove his case, he should be able to catch Gabe in the act of handling the precious stones, and with a witness present.

So he put the small cardboard box back into the cavity of the hollow oak, just as near where he had found it as he could. Then, with a cautious look along the trail, to make sure Gabe was not already returning, Fred hurried away.

He was unusually quiet at lunch time, his mother and sister noticed. They even asked him if he felt unwell; but Fred laughingly replied that he never was better in all his life.
