"Don't do that! We don't know what boat holds Peggy," commanded Brewster. "Keep cool, boys, and be ready to scrap if we have to." He was half mad with fear and anxiety, and he was determined to exterminate the bands of robbers if harm came to the girl in their power. "She's in the second boat," came the cry from the yacht, and the searchlight was kept on that particular object almost to the exclusion of the others. But Captain Perry saw the wisdom of keeping all of them clearly located in order to prevent trickery. Brewster's brawny sailor boys came up like greyhounds, cheering as they dashed among the boats of the fugitives. Three or four shots were fired into the air by the zealous American lads, and there were loud cries from the Arabs as they veered off panic-stricken. Monty's boat was now in the path of light and not far behind the one which held Peggy. He was standing in the bow. "Take care of the others!" he called back to his followers. "We'll go after the leaders." The response from behind was a cheer, a half dozen shots and some of the most joyous profanity that ever fell from the lips of American sailors, mingled with shrieks from the boats they were to "take care of." "Stop!" Brewster shouted to the Arabs. "Stop, or we'll kill every one of you!" His boat was not more than fifty feet from the other. Suddenly a tall, white-robed figure arose in the middle of the Egyptian craft, and a moment later the pursuers saw Peggy's form passed up to him. She was instantly clasped by one of his long arms, and the other was lifted high above her. A gleaming knife was held in the upraised hand. "Fire on us if you dare!" came in French from the tall Arab. "Dog of an American, she shall die if you come near her!" CHAPTER XXV THE RESCUE OF PEGGY Brewster's heart almost ceased beating, and every vestige of color left his face. Clear and distinct in the light from the yacht the Arab and his burden were outlined against the black screen beyond. There was no mistaking the earnestness of the threat, nor could the witnesses doubt the ghastly intention of the long, cruel knife that gleamed on high. Peggy's body served as a shield for that of her captor. Brewster and Bragdon recognized the man as one of Mohammed's principal retainers, a fierce-looking fellow who had attracted more than usual attention on the day of the sheik's visit. "For God's sake, don't kill her!" cried Brewster in agonized tones. There was a diabolical grin on the face of the Arab, who was about to shout back some defiant taunt when the unexpected happened.
