"This ees the man!" he panted triumphantly, as he sprang at Greg.
Carker flung up his arm, and Murillo's knife slashed his sleeve from shoulder to elbow.
In a twinkling Greg had closed with the Mexican, grasping the man's wrist and holding him in an effort to keep him from using the knife.
Juanita sought to interfere, but the cool, determined young American warned her back.
"Leave this man to me," he said.
"He has the knife!"
"But I don't think he'll use it," said Carker, as he backheeled Murillo.
In a moment they were down, twisting and squirming and writhing on the ground.
With her hands clasped, and her lips parted, Juanita looked on, standing ready to do her best should she see Murillo free his knife hand.
Carker had once been an athlete. He was not now in the best condition, but, nevertheless, he was stronger than his foe, and he finally pinned Murillo to the ground.
