finish, for the thought that had come to his mind, while it seemed the only reasonable solution of the mystery, appeared at the same time quite improbable. Presently the men in the street went away. The courtyard and the cafe were deserted. Cautiously Tarzan lowered himself to the sill of the girl’s window. The room was empty. He returned to the roof and let Abdul down, then he lowered the girl to the arms of the waiting Arab.
From the window Abdul dropped the short distance to the street below, while Tarzan took the girl in his arms and leaped down as he had done on so many other occasions in his own forest with a burden in his arms. A little cry of alarm was startled from the girl’s lips, but Tarzan landed in the street with but an imperceptible jar, and lowered her in safety to her feet.
She clung to him for a moment.
“How strong m’sieur is, and how active,” she cried. “El Adrea, the black lion, himself is not more so.”
“I should like to meet this El Adrea of yours,” he said. “I have heard much about him.”
“And you come to the douar of my father you shall see him,” said the girl. “He lives in a spur of the mountains north of us, and comes down from his lair at night to rob my father’s douar. With a single blow of his mighty paw he crushes the skull of a bull, and woe betide the belated wayfarer who meets El Adrea abroad at night.”
Without further mishap they reached the hotel. The sleepy landlord objected strenuously to instituting a search for Kadour ben Saden until the following morning, but a piece of gold put a different aspect on the matter, so that a few moments later a servant had started to make the rounds of the lesser native hostelries where it might be expected that a desert sheik would find congenial associations. Tarzan had felt it necessary to find the girl’s father that night, for fear he might start on his homeward journey too early in the morning to be intercepted.
They had waited perhaps half an hour when the messenger returned with Kadour ben Saden. The old sheik entered the room with a questioning expression upon his proud face.
“Monsieur has done me the honor to—” he commenced, and then his eyes fell upon the girl. With outstretched arms he crossed the room to meet her. “My daughter!” he cried. “Allah is merciful!” and tears dimmed the martial eyes of the old warrior.
When the story of her abduction and her final rescue had been told to Kadour ben Saden he extended his hand to Tarzan.
“All that is Kadour ben Saden’s is thine, my friend, even to his life,” he said very simply, but Tarzan knew that those were no idle words.
It was decided that although three of them would have to ride after practically no sleep, it would be best to make an early start in the morning, and attempt to ride all the way to Bou Saada in one day. It would have been comparatively easy for the men, but for the girl it was sure to be a fatiguing journey.
She, however, was the most anxious to undertake it, for it seemed to her that she could not quickly enough reach the family and friends from whom she had been separated for two years.
It seemed to Tarzan that he had not closed his eyes before he was awakened, and in another hour the party was on its way south toward Bou Saada. For a few miles the road was good, and they made rapid progress, but suddenly it became only a waste of sand, into which the horses sank fetlock deep at nearly every step. In addition to Tarzan, Abdul, the sheik, and his daughter were four of the wild plainsmen of the sheik’s tribe who had accompanied him upon the trip to Sidi Aissa. Thus, seven guns strong, they entertained little fear of attack by day, and if all went well they should reach Bou Saada before nightfall.
A brisk wind enveloped them in the blowing sand of the desert, until Tarzan’s lips were parched and cracked. What little he could see of the surrounding country was far from alluring—a vast expanse of rough country, rolling in little, barren hillocks, and tufted here and there with clumps of dreary shrub. Far to the south rose the dim lines of the Saharan Atlas range. How different, thought Tarzan, from the gorgeous Africa of his boyhood!
Abdul, always on the alert, looked backward quite as often as he did ahead. At the top of each hillock that they mounted he would draw in his horse and, turning, scan the country to the rear with utmost care. At last his scrutiny was rewarded.
“Look!” he cried. “There are six horsemen behind us.”
“Your friends of last evening, no doubt, monsieur,” remarked Kadour ben Saden dryly to Tarzan.
“No doubt,” replied the ape-man. “I am sorry that my society should endanger the safety of your journey. At the next village I shall remain and question these gentlemen, while you ride on. There is no necessity for my being at Bou Saada tonight, and less still why you should not ride in peace.”
“If you stop we shall stop,” said Kadour ben Saden. “Until you are safe with your friends, or the enemy has left your trail, we shall remain with you. There is nothing more to say.”
Tarzan nodded his head. He was a man of few words, and possibly it was for this reason as much as any that Kadour ben Saden had taken to him, for if there be one thing that an Arab despises it is a talkative man.
All the balance of the day Abdul caught glimpses of the horsemen in their rear. They remained always at about the same distance. During the occasional halts for rest, and at the longer halt at noon, they approached no closer.
“They are waiting for darkness,” said Kadour ben Saden.
And darkness came before they reached Bou Saada. The last glimpse that Abdul had of the grim, white-robed figures that trailed them, just before dusk made it impossible to distinguish them, had made it apparent that they were rapidly closing up the distance that intervened between them and their intended quarry. He whispered this fact to Tarzan, for he did not wish to alarm the girl. The ape-man drew back beside him.
“You will ride ahead with the others, Abdul,” said Tarzan. “This is my quarrel. I shall wait at the next convenient spot, and interview these fellows.”
“Then Abdul shall wait at thy side,” replied the young Arab, nor would any threats or commands move him from his decision.
“Very well, then,” replied Tarzan. “Here is as good a place as we could wish. Here are rocks at the top of this hillock. We shall remain hidden here and give an account of ourselves to these gentlemen when they appear.”
They drew in their horses and dismounted. The others riding ahead were already out of sight in the darkness. Beyond them shone the lights of Bou Saada. Tarzan removed his rifle from its boot and loosened his revolver in its holster. He ordered Abdul to withdraw behind the rocks with the horses, so that they should be shielded from the enemies’ bullets should they fire. The young Arab pretended to do as he was bid, but when he had fastened the two animals securely to a low shrub he crept back to lie on his belly a few paces behind Tarzan.
The ape-man stood erect in the middle of the road, waiting. Nor did he have long to wait. The sound of galloping horses came suddenly out of the darkness below him, and a moment later he discerned the moving blotches of lighter color against the solid background of the night.
“Halt,” he cried, “or we fire!”
The white figures came to a sudden stop, and for a moment there was silence. Then came the sound of a whispered council, and like ghosts the phantom riders dispersed in all directions. Again the desert lay still about him, yet it was an ominous stillness that foreboded evil.
