The girl's eyes flashed angrily.

"Castillo is a fool! He pulls down what others have carefully built up."

"That is what nearly happened this afternoon. I believe you are to be trusted, señores?"

Grahame bowed.

"I am an adventurer, not a patriot, and my partner is out for money, but we made a bargain with Don Martin and we keep our word."

"Then," said the girl quietly, "Castillo is hiding here."

"In the casa Sarmiento! Isn't that dangerous? Won't the President's friends suspect?"
