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!”
