"So shall I after I have found out about Santiago's connection with that ten thousand pounds."

"That's right," was the laughing rejoinder. "Stick to it, Billie, and who knows what may happen?"

"Do you know," remarked Adrian slowly, "I'm beginning to be considerably worried for the Americans scattered throughout Mexico."

"Why should you be?" from Donald.

"I remember Pedro's words that, if the United States did anything, Carranza would unite with Huerta."

"I don't believe he would."

"Maybe not. But the Zapata brothers will think this a good time to make the Americans trouble. I was thinking of Mr. Black and Josie."

"I'll bet you were," laughed Billie. "I wouldn't be surprised if they were thinking about you. Hey, Don?"

"Well, they might do worse," said Donald. "There are worse fellows than Adrian."

"That's right," retorted Adrian good-humoredly. "I can stand it. But, just the same, I wish I knew they were safe."
