“There is much treasure at my command. Not a mere handful of gems shall be yours, but enough to make your tribe wealthy for all time to come.”

“I believe that my brother speaks truth.”

“Then,” said Kāra, relieved, “I ask you to kill Winston Bey as a proof of your confidence in me. The others may live until we get to Fedah.”

“Tah! What is the use of dividing the ceremony?” returned the sheik, with a gesture of indifference. “I like not this pig-sticking in sections. It means cleaning one’s knife several times instead of once. Be patient, my brother. When we have arrived at Fedah and our friendship is further cemented by your royal generosity, then will I accomplish all the killing in a brief space and have done with it. Is it not so?”

Kāra hesitated, but saw clearly that the wily sheik would not trust him. Moreover, he feared that Winston’s eager offers to outbid him, if persistently repeated, might prove effectual unless he carried out his own promises to the greedy Arab. He had not expected to pay Antar any great price for his services, and in the beginning intended that the “handful” of gems would be a very small one; but Antar had entrapped him cleverly, and he now realized he must expend an exorbitant sum to induce the old sheik to obey his orders.

After all, that did not matter. The entire treasure had been Hatatcha’s before it descended to him, and a portion of it would be well expended in securing her vengeance. He alone knew that the hoard was practically inexhaustible, and he might even bury the big Arab in jewels and golden ornaments and still have left more than he could use in his own lifetime.

So he agreed, with assumed content, to Antar’s proposition, and Abdallah, the engineer, was released from his bonds and instructed to start the dahabeah upon its voyage up the river. It would be thirty hours before they could hope to reach Fedah.

Roane and Winston were permitted to remain upon deck, but were tied to their chairs and carefully guarded. Breakfast was served, and Kāra accompanied the Arab who carried the tray to the cabin of the women. The Egyptian had not disturbed them since the night before, well knowing they had made themselves as secure as he could have done.

He rapped boldly upon the door and said:

“Let me in.”
