When he had read over the notes he had made Tom O.K.'d them. "That is about as I had the items set down myself on the sheet that fellow stole from me."

"Wait!" exclaimed Ned, as Tom arose from his chair. "Do you know what strikes me after your telling me about your second hold-up?"

"What's that?" asked his chum.

"Are you sure that was the same fellow who stole your wallet?"

"Quite sure."

"Then his second attack on you proves that he got wise to the fact that your notes were in shorthand. He had a chance to study them while you visited with Mary Nestor."

"Like enough."

"I wonder if it doesn't prove that the fellow has somebody in cahoots with him right here in Shopton?" ruminated Ned.

"Bless my spare tire!" ejaculated Mr. Damon, who had already started for the door but now turned back.

"That's an idea, Ned," agreed Tom Swift. "It would seem that he had consulted with some superior," said the young manager of the Swift Construction Company. "This hold-up man may be from the West; but perhaps he did not follow Bartholomew alone."
