"He might have injured you, though," said Mr. Jackson. "We'll go outside now, and look--"

"Is any one killed? Are you both murdered?" cried Mrs. Baggert at the dining-room door. "If any one is killed I'm not coming in there. I can't bear the sight of blood."

"No one is hurt," declared Tom with a laugh. "Come on in, Mrs. Baggert," and the housekeeper entered, her hair all done up in curl papers.

"Oh, my goodness me!" she exclaimed. "When I heard that cannon go off I was sure the house was coming down. How is it some one wasn't killed?"

"That wasn't a cannon; it was only my little rifle," said Tom, and then he told again, for the benefit of the housekeeper, the story of what had happened.

"We'd better hurry and look around the premises," suggested Mr. Jackson. "Maybe he is hiding, and will come back, or perhaps he has some confederates on the watch."

"Not much danger of that," declared Tom. "Happy Harry is far enough away from here now, and so are his confederates, if he had any, which I doubt. Still, it will do no harm to take a look around."

A search resulted in nothing, however, and the Swift household had soon settled down again, though no one slept soundly during the remainder of the night.

In the morning Tom sent word of what had happened to the police of Shopton. Some officers came out to the house, but, beyond looking wisely at the window by which the burglar had entered and at some footprints in the garden, they could do nothing. Tom wanted to go off on his motor-cycle on a tour of the surrounding neighborhood to see if he could get any clews, but he did not think it would be wise in the absence of his father. He thought it would be better to remain at home, in case any further efforts were made to get possession of valuable models or papers.

"There's not much likelihood of that, though," said Tom to the old engineer. "Those fellows have what they want, and are not going to bother us again. I would like to get that model back for dad, though. If they file it and take out a patent, even if he can prove that it is his, it will mean a long lawsuit and he may be defrauded of his rights, after all. Possession is nine points of the law, and part of the tenth, too, I guess."
