Quickly Tom told of what had happened at his place.
"I begin to see through it," he said. "There is some plot here, and we've got to get to the bottom of it. Mr. Damon either went with these men in the airship willingly, or he was taken away by force. I'm inclined to think he went of his own accord, or you would have heard some outcry, Mrs. Damon."
"Well, perhaps so," she admitted. "But would he go away in that manner without telling me?"
"He might," said Tom, willing to test his theory on all sides. "He might not have wanted you to worry, for you know you dislike him to go up in airships."
"Yes, I do. Oh, if I only thought he did go away of his own accord, I could understand it. He went, if he did, to try and save his fortune."
"It does look as though he had an appointment with someone, Tom," suggested Ned. "His looking at the clock, and then going out, and all that."
"Yes, admitted the young inventor, "and now I'm inclined to change my theory a bit. It may have been some other airship than mine that was used."
"How so?" asked Ned.
