The noise that he heard was little more than an imperceptible rustling, but presently it assumed a new volume and a new significance, so that now he was sure that it was someone running rapidly along the trail, and not one but two—he distinctly heard the footfalls of the heavier creature mingling with those he had first heard.

And then he heard a man's voice cry "Stop!" and now the sounds were very close to him, just around the first bend ahead. The sound of running feet stopped, to be followed by that of a scuffle and strange oaths in a man's voice.

And then a woman's voice spoke, "Let me go! You will never get me where you are taking me alive."

"Then I'll take you for myself now," said the man.

Colt had heard enough. There had been something familiar in the tones of the woman's voice. Silently he dropped to the trail, drawing his dagger, and stepped quickly toward the sounds of the altercation. As he rounded the bend in the trail, he saw just before him only a man's back—by thôb and thorrîb an Aarab—but beyond the man and in his clutches Colt knew the woman was hidden by the flowing robes of her assailant.

Leaping forward, he seized the fellow by the shoulder and jerked him suddenly about; and as the man faced him Colt saw that it was Abu Batn, and now, too, he saw why the voice of the woman had seemed familiar—she was Zora Drinov.

Abu Batn purpled with rage at the interruption, but great as was his anger so, too, was his surprise as he recognized the American. Just for an instant he thought that possibly this was the advance guard of a party of searchers and avengers from Zveri's camp, but when he had time to observe the unkempt, disheveled, unarmed condition of Colt he realized that the man was alone and doubtless lost.

"Dog of a Nasrâny!" he cried, jerking away from Colt's grasp. "Lay not your filthy hand upon a true believer." At the same time he moved to draw his pistol, but in that instant Colt was upon him again, and the two men went down in the narrow trail, the American on top.

What happened then, happened very quickly. As Abu Batn drew his pistol, he caught the hammer in the folds of his thôb, so that the weapon was discharged. The bullet went harmlessly into the ground, but the report warned Colt of his imminent danger, and in self defense he ran his blade through the sheykh's throat.

As he rose slowly from the body of the sheykh, Zora Drinov grasped him by the arm. "Quick!" she said. "That shot will bring the others. They must not find us."
