"What is it then?"

"Those scoundrels are around again, Tom!" and Mr. Swift looked apprehensively about him.

"You mean the men who stole the turbine model?"

"Yes. I was walking in the woods near the hotel yesterday and I saw Anson Morse. He did not see me, for I turned aside as quickly as I had a glimpse of him. He was talking to another man."

"What sort of a man?"

"Well, an ordinary enough individual, but I noticed that he had tattooed on the little finger of his left hand a blue ring."

"Happy Harry, the tramp!" exclaimed Tom. "What can he and Morse be doing here?"

"I don't know, Tom, but I'm worried. I wish I was back home. I'm afraid something may happen to some of my inventions. I want to go back to Shopton, Tom."

"Nonsense, dad. Don't worry just because you saw some of your former enemies. Everything is all right at home. Mrs. Baggert and Garret Jackson will look after things. But, if you like, I, can find out for you how matters are."

"How, Tom?"
