A half hour later the four men returned to their plane but four armed doughboys went there with them. The Captain and a co-pilot took charge of the plane.

“Mary, you’re a wonder!” Sparky exclaimed as that plane climbed the sky.

“Who are they?” she asked in a whisper.

“That,” said Sparky, “is a military secret.”

“Where are they going?” she asked.

“I don’t exactly know.” Sparky smiled. “One thing I’m sure of, and that is they won’t come back.”

“One thing still puzzles me,” said Mary.

“What’s that,” Sparky asked.

“Why did the Captain order me to open the plane’s cabin door for those men?”

“Perhaps he knew you didn’t have the key. Then again he may have known you wouldn’t use it if you did have it. Either way he was right. What he wanted was to avoid any shooting, and he got that. I wouldn’t trade you and Hop Sing for four Lieutenant Colonels and a General,” Sparky laughed. “And you’re both going with us to China.”
