Apparently Algernon was “some talker,” as Josh put it. Once he got started, and he was like a seven-day clock in action. And Jack chuckled to think that they had been looking upon all this as assumed, and that the millionaire’s pampered boy had been a desperate thief, playing a little game. It was one of the most ridiculous happenings that had ever come to the motor boat chums.
And as Algernon was talking a sudden idea had leaped into Jack’s active mind. This time it was founded on facts that were absolutely true, and could be relied upon.
It all hinged on that wonderful sweater belonging to Buster, and which was so queerly marked with a blue moon.
Now Jack knew positively that the same garment had been in the shed where the trio of motor boats were lying, awaiting the beginning of the cruise, on the previous evening, for he had handled it himself. Buster could not find it when he wanted to wear it later on, and the rest believed that it had been carelessly left somewhere in the shop or shed, though as we have seen, the fat boy suspected Josh of playing a sly trick on him.
Now the fact that this strange man was actually wearing the novel sweater was positive evidence that he must have been in the shop of the boat builder on the previous night, for some purpose or other, and had taken the garment then, perhaps because it looked warm, and he anticipated a chilly ride down the river.
Yes, Jack had jumped to a conclusion in the matter. Although his first guess with regard to the identity of Algernon and Jenks had been a bad one, he believed he could do much better with this other fellow; and whom he now believed to be one of the desperate scoundrels who had broken into the bank at Lawrence.
A lot of things went to point that way; and Buster’s sweater was the only connecting clue, as it were. How the men happened to be on the island, and why one of them was ready to take chances in stealing some of their food, of course Jack was hardly in a condition to say just then. They must have been pretty hungry, which would indicate that they could not have had any food aboard their boat at the time they fled from pursuit. Perhaps some accident had happened to the craft in which they had come down the river. That would account for the fellow stealing the fine new motor boat belonging to the tenderfoot cruiser, Algernon. It may have taken his fancy for some reason or other; perhaps because it happened to resemble their own craft, now disabled.
