"I'll call for that money in about two hours," he said. "I ain't saying good-by, Captain. I'll see yuh later."

Captain Riley stood smiling to himself while he watched the Thunder Bird take the air. That it took the air smoothly, spiraling upward as gracefully as any of his young flyers could do, did not escape him. Nor did the steadiness with which it finally swung away to the southeast.

"That boy's a born flyer," he observed to his favorite first lieutenant, who just happened to be standing near. "They say he never has had any training under an instructor. He just flew. He'll make good—a kid like that is bound to."

Up in the Thunder Bird Johnny was thinking quite different thoughts. "He thinks I won't be able to deliver the goods. He was nice and friendly, all right—good golly, he'd oughta be! He admitted right out plain that they wanted Cliff bad. But he's hanging on to my money so he'll have some hold over me if I don't bring in Schwab for him. And if I don't, and go back for my money, he'll—well, firing squad won't be any kidding, is what I mean.

"O-h-h, no! Captain Riley can't fool me! Wouldn't tell me to get Schwab over here—didn't dare tell me. But he makes it worth a whole lot to me to get him, just the same. He knows darn well if I don't I'll never dare to go back, and he'll be over seven thousand dollars better off." Johnny, you will observe, had quite forgotten that receipt in his pocket, which Captain Riley might find it hard to explain if he attempted to withhold the money.

His doubt of the Captain increased when, looking back, he spied two swift scouting planes scudding along a mile or two behind him. That they might be considered a guard of honor rather than spies sent out to see that he did not play false never occurred to him.

"Aw, you think maybe I won't do it!" he snorted angrily, his young vanity hurt. "All right, tag along and be darned. I'll have Schwab and be flying back again before you can bank around to fly hack and tattle where I went. That's what I mean. I ain't going to be done outa no seven thousand dollars; I'll tell the world I ain't."

Getting Schwab was absurdly simple, just as Johnny had felt sure it would be. He flew to where he would be expected to cross the line had he come from Los Angeles. Schwab would be impatient, anxious to get in his fingers the money Cliff was supposed to bring. He did not wait at the house, but came out to meet the Thunder Bird. Johnny had been sure that he would do that very thing.

To keep the nose of the Thunder Bird toward Schwab so that he could not see that only one man returned with her was simple. Until he was close Schwab did not suspect that Cliff was not along. Even then he was not suspicious, but came hurrying up to know why Johnny came alone. Schwab wanted that money—they always do.

"Where's my man?" he demanded of Johnny, who had brought the landing gear against an old fence post used to block the wheels, and shut the motor off as much as he could and keep it running.
