“But there was no need. The men were quiet enough. They ordered hamburger steak and onions—a vile combination, I’ll say—and coffee. While they were eating the third man came in—now I have it right—and as soon as the two who had previously entered saw him one of them asked:
“What about our quick friend?”
“ ‘The speedy one is chained up where he can’t do any harm,’ is what the third man said. Then they laughed and the third man also ordered hamburger steak and onions and they began to eat as if they were half-starved.
“I didn’t pay much attention to them at the time, for I was in a hurry to get home—I had told my wife I would arrive at midnight, but the train was late and I knew I’d have to explain why I was out at that hour. So I hurried up with my meal and was coming out when one of the men happened to say:
“ ‘Well, this will put the airline express matter right in our hands!’ It wasn’t until then, as I was coming out and heard this remark, that I began to suspect something.”
“The airline express!” exclaimed Mr. Swift. “Why, that’s Tom’s latest idea!”
“I know it is,” said Mr. Damon. “That’s what made me suspicious. Then I put two and two together—they had spoken about ‘our quick friend,’ and the ‘speedy one,’ and now I know by those words that they meant Tom.”
“It begins to look like that!” cried Ned. “But what was it they said about him—that he was tied up?”
“ ‘Chained up,’ was the expression they used,” Mr. Damon said. “I at once made up my mind that some of Tom’s enemies were plotting against him and I decided to come right over and let him know. I waited a moment after coming out of the lunch wagon, and saw the three plotters disappear down a street that led to a wharf on Lake Carlopa. Then I caught a night-cruising taxi and made for my hangar. I decided to try to call you first by telephone, and, if I couldn’t raise you to warn you to look out, I would aeroplane over and give the alarm.
“Well, I couldn’t get you on the wire, so I roused my mechanic and we wheeled the plane out to my landing field. I didn’t even bother to call up my wife, for I knew she wouldn’t let me go, and I started off and—here I am.”
