“Father, do you suppose some one is trying to get us into trouble?”
“Who, for instance?”
“Well, Mr. Saxton.”
“Why should he? No, he will not disturb me as long as I keep quiet about that suit on the patents.”
“I don’t like these mysterious night callers,” said Ben.
“They haven’t done us any harm yet.”
“But they may. Some one did visit the work shed last night.”
“How do you know that?”
Ben showed the strange pin he had found, and told his suspicions.
“You mustn’t let these things bother you, Ben,” advised his father sensibly. “No harm has been done to our machine as yet. I intend to lay a wire around the yard connected with a bell in the house, that will alarm us if anybody comes near the work shed.”
