Usually he saw things long before others were aware that there was anything to see—a trait that had won for him the sobriquet of Hawk. Now he saw, just beyond the long shadows, a dozen specks rising and falling among the sands. They disappeared and reappeared, but always they grew larger. Jacot recognized them immediately. They were horsemen—horsemen of the desert. Already a sergeant was running toward him. The entire camp was straining its eyes into the distance. Jacot gave a few terse orders to the sergeant who saluted, turned upon his heel and returned to the men. Here he gathered a dozen who saddled their horses, mounted and rode out to meet the strangers. The remaining men disposed themselves in readiness for instant action. It was not entirely beyond the range of possibilities that the horsemen riding thus swiftly toward the camp might be friends of the prisoners bent upon the release of their kinsmen by a sudden attack. Jacot doubted this, however, since the strangers were evidently making no attempt to conceal their presence. They were galloping rapidly toward the camp in plain view of all. There might be treachery lurking beneath their fair appearance; but none who knew The Hawk would be so gullible as to hope to trap him thus.

The sergeant with his detail met the Arabs two hundred yards from the camp. Jacot could see him in conversation with a tall, white-robed figure—evidently the leader of the band. Presently the sergeant and this Arab rode side by side toward camp. Jacot awaited them. The two reined in and dismounted before him.

"Sheik Amor ben Khatour," announced the sergeant by way of introduction.

Captain Jacot eyed the newcomer. He was acquainted with nearly every principal Arab within a radius of several hundred miles. This man he never had seen. He was a tall, weather beaten, sour looking man of sixty or more. His eyes were narrow and evil. Captain Jacot did not relish his appearance.

"Well?" he asked, tentatively.

The Arab came directly to the point.

"Achmet ben Houdin is my sister's son," he said. "If you will give him into my keeping I will see that he sins no more against the laws of the French."

Jacot shook his head. "That cannot be," he replied. "I must take him back with me. He will be properly and fairly tried by a civil court. If he is innocent he will be released."

"And if he is not innocent?" asked the Arab.

"He is charged with many murders. For any one of these, if he is proved guilty, he will have to die."

The Arab's left hand was hidden beneath his burnous. Now he withdrew it disclosing a large goatskin purse, bulging and heavy with coins.
