As it happened, the senior Mr. North had been just behind her when she greeted his son and the latter's opening remarks had given him food for lively conjecture. Dexterously, considering his bulk, he had insinuated himself into and through a screening group of people and rejoined his hostess near the door. Where and when could that boy of his have encountered Willa Murdaugh?

The man with the scarred forehead took her in to dinner and Willa listened politely to his rather heavy pleasantries, studying him the while through narrowed eyes. Of a type foreign to the frequenters of the Blue Chip, he had not crossed her path in Limasito, but his previous activities there were an open book to her. She knew that his methods in acquiring more than one lease had been unscrupulous and his reputation none too good, yet the man interested her.

"Your cousin tells me that you've been in Mexico yourself." He turned his small eyes, sleepily bright, upon her. "Says you've picked up an uncommon lot of knowledge about the petroleum industries."

"I've heard them discussed, that is all," Willa deprecated. "Naturally, they're the main subject down there, after government upheavals, of course. It would be a good thing if the States took the oil lands under protection, wouldn't it?"

He laughed shortly.

"Good for us. It will come in time, too. A few more outrages——"

"Yes." Willa interposed softly. "Even the less important disturbers, like El Negrito for instance, have their uses."

"El Negrito?" He laid down his knife and fork. "That's what they call Alvarez, isn't it? I didn't know his fame had spread all over Mexico. You were at school there, I understand."

Willa shook her head.

"Not lately. I happened to be among those present when El Negrito made his last sortie from the hills."
