"Rags and tatters. No one came. Nobody outside knows there is such a place as Dead Hole, except by vague report. Dad and I just happened to stumble into it. About advertising Elsie, we tried that some. There was no answer. We think she belonged to a stray family, out prospecting. The others must have died of thirst."

"Or were murdered by Cochise," put in Lennon.

Carmena's eyes narrowed.

"Maybe—maybe not. It was just after he jumped the Reservation. But he was only a sulky schoolboy then, playing hookey. Besides, he had not harmed the child. He worked for Dad and was right decent, till he got in with Slade and the—business started."

Lennon was not to be diverted to another subject. The mystery of Elsie's parentage intrigued him. With the realization that the two girls were not of blood kin, Lennon found himself dwelling upon the differences between them. Elsie, cleared of any kinship to Farley, at once became in his thoughts a being of finer nature than her foster-sister.

In contrast, Carmena now seemed to show distinctly the taint of Farley's blood. Her frank manner took on the tinge of boldness. Her vigour and strength now seemed mannish, if not coarse.

Might not what he had taken for high spirit and courage be no more than callous hardihood? Was there not a certain garishness about her rich colouring? And was all the brown of her skin on the outside? Both her hair and eyes were dark, and there was her Spanish name—Carmena. Was she not, in part, of Mexican blood?

Some hint of Lennon's thoughts may have shown in his expression. Otherwise the girl's next remark was pure coincidence:

"Ever since Slade added tizwin to the business, I've had to be pretty much the man of the family. He persuaded us that Dad would die without a lot of stimulant. That's how he got hold of Dad. Once the habit was fixed, I couldn't break Dad of it. With you here, I'm hoping he may remember his old grit and pride, and brace up."

"But about your—foster-sister," said Lennon.
