“Bless my soul—what’s this?—circus—bing-bang—through a hoop—whoop-la!” he exclaimed.

“Not exactly,” said Mr. Jesson, with a smile at the inventor’s rapid-fire speech; “but I’ll explain later on. First tell us about the strange men. Possibly we can throw some light on the matter. The boys told me about encountering two men on the road last night, who asked about you, and whom we saw again just now.”

“One of them with a red beard—long one—other chap had black moustache—eh?”

“Yes, that describes the fellows as accurately as we could size them up for their goggles,” struck in Jack, who meanwhile had started the machine again. He drove it up to the front door of Mr. Peregrine’s home, and when they had all alighted a man was detailed to take it to the barn. Within they found a good lunch awaiting them, and Mrs. Peregrine came to meet them with a smile of ready welcome.

As all the passengers were rather grimy, they first had a good wash, and Ralph was provided with a suit which had belonged to Mr. Peregrine’s son, now a lad of nineteen and away at college. During the meal Mr. Peregrine described how, on visiting the shed which housed his invention that morning, he had surprised a strange man with a red beard peeping through a window at it.

“I must tell you,” he continued, “that a powerful syndicate has tried to purchase my invention; but I have refused to sell. Since that time I have been harassed in many ways, and I am afraid that this is their latest move against me.”

When Mr. Peregrine was very much in earnest he dropped his odd way of talking, and there was no doubt but that he was very serious now. His wife, too, looked troubled. Clearly his enemies were powerful, and determined enough to cause the inventor considerable alarm.

“But surely your invention is patented, and you have nothing to fear on the score of their stealing your ideas?” asked Mr. Jesson.

“That’s just it,” said the inventor, with a troubled look; “I have taken no steps in the matter of a patent yet, as I feared a leak somewhere. These people who are after my vanishing gun are aware of this, too, as they have spies in Washington.”

“Well, that does make the matter serious,” agreed Mr. Jesson, and then, as Mrs. Peregrine looked rather alarmed, the subject was changed.
