Why, it really looked as though the luck that had come to the Fentons only the day before might still be following him, even in his desire to do his chum a good turn.

Perhaps the golden opportunity to find out something about Black Joe's tricks might be close at hand. How little he had dreamed of this when leaving his home only a few minutes before.

"Once in a great while," the lady went on to explain, "Joe gets a stubborn fit, and refuses to mind when I tell him to come to me. It always exasperates me; and twice before I've sent for the gardener to come and get the step-ladder, so that he can chase the rascal from pillar to post until finally he would fall into my grasp. I punish him by chaining him fast to that perch for a week; and as a rule he seems to amend his ways for a long time. But the last occasion failed most miserably, I must confess. Do you think you are strong enough to carry the step-ladder up from the basement, Fred?"

Fred had some difficulty in keeping his face free from a smile. The idea of her doubting his muscular ability, after all the athletic exercises he practiced; but then of course Miss Muster would not know that; so he only replied that he believed he would have no difficulty in doing all she required.

CHAPTER XIV

THE MISSING OPALS AGAIN

Following out the injunctions of Miss Muster, Fred easily found where the step-ladder was kept in the basement. Nor did he have the slightest difficulty in carrying it up the stairs after he had discovered it.

He noticed that the lady was very particular to keep the door of the living room closed; and remembered that it had been in that condition at the time of their first arrival.

"The artful rogue," Miss Muster explained; "would be only too glad to fly out, and scour the entire house, laughing at me, and mocking me as though possessed of the spirit of evil our great poet Edgar Allan Poe gave to the raven. But now that you have succeeded in getting the ladder, we shall soon corner him."
