"Good!" breathed Hooker, as he rose in his stirrups and looked.

"Why good?" she demanded curiously.

"The's only three of 'em," answered Bud. "I was afraid they might be in front," he explained, as she gazed at him with a puzzled smile.

"Yes," she said; "but what will you do if they catch us?"

"They won't catch us," replied Hooker confidently. "Not while I've got my rifle. Aha!" he exclaimed, still looking back, "now we know all about it—that sorrel is Manuel del Rey's!"

"And will you kill him?" challenged Gracia, rousing suddenly at the name. Hooker pretended not to hear. Instead, he cocked his eye up at the eastern mountain, whence from time to time came muffled rifle-shots, and turned his horse to go. There was trouble over there to the east somewhere—Alvarez and his Yaquis, still harrying the retreating rebels—and some of it might come their way.

"Ah, how I hate that man!" raged Gracia, spurring her horse as she scowled back at the galloping Del Rey and his men who were riding onward rapidly.

"All right," observed Bud with a quizzical smile, "I'll have to kill him for you then!"

She gazed at him a moment with eyes that were big with questioning, but the expression on his rugged face baffled her.

"I would not forget it," she cried impulsively. "No, after all I have suffered, I think I could love the man who would meet him face to face! But why do you—ah!" she cried, with a sudden tragic bitterness. "You smile! You have no thought for me—you care nothing that I am afraid of him! Ah, Dios, for a man who is brave—to rid me of this devil!"
