Afterward he placed the pelt upon his shoulder and set forth upon his return to his people. He returned directly to the cliffs by the Restless Sea, for he did not know whether the tribe had yet left in search of the new camping ground or not. It was night by the time he emerged from the jungle at the foot of the cliff. A cursory exploration showed him that the tribe had gone, and so he crawled into his own cave for the night. In the morning he easily could overtake them.
When Hud crossed the cave toward Nat-ul he had expected to encounter physical resistance, and so he came half crouched and with hands outstretched to seize and subdue her.
"Hud," said the girl, "if I come to you willingly will you treat me kindly always?"
The man came to a stop a few feet from his victim. Evidently it was going to be more easy than he had anticipated. He did not relish the idea of taking a she-tiger for mate, and so he was glad to make whatever promises the girl required. Afterward he could keep such as were easiest to keep.
"Hud will be a kind mate," he answered.
The girl stepped toward him, and Hud met her with encircling arms; but as hers went around him he failed to see the sharp stone knife in Nat-ul's right hand. The first he knew of it was when it was plunged remorselessly into his back beneath his left shoulder blade. Then Hud tried to disengage himself from the girl's embrace, but struggle as he would, she clung to him tenaciously, plunging the weapon time and time again into his back.
He tried to reach her throat with his fingers, but her sharp teeth fastened upon his hand, and then, with his free hand, he beat upon her face, but only for an instant, as the knife found his heart, and with a groan he sank to the rocky floor of the cave.
Without waiting to know that he was dead Nat-ul rushed from the dark interior. Swiftly she scaled the Barren Cliffs and dropped once more into her own valley upon the other side. Along the beach she raced back toward the dwellings of her people, not knowing that at that very moment they were setting out in search of a new home. At mid-afternoon she passed them scarce half a mile away, for they had taken the way that led upon the far side of the jungle that they might meet the returning mammoth hunters, and so Nat-ul came to the deserted caves of her tribe at nightfall only to find that her people had departed.
Supperless, she crawled into one of the smaller and higher caves, for it would be futile to attempt to discover the trail of the departed tribe while night with its darkness and its innumerable horrors enveloped the earth. She had dozed once when she was awakened by the sound of movement upon the face of the cliff. Scarce breathing, she lay listening. Was it man or beast that roamed through the deserted haunts of her tribe? Higher and higher up the face of the cliff came the sound of the midnight prowler. That the creature, whatever it was, was making a systematic search of the caves seemed all too apparent. It would be but a question of minutes before it would reach her hiding place.
