Tarzan stepped toward the doorway of the cave and looked out. Night had just fallen. He could hear voices from the nearer caves and there floated to his nostrils the odor of cooking food. He looked down and experienced a sensation of relief. The cave in which he had been held was in the lowest tier--scarce thirty feet from the base of the cliff. He was about to chance an immediate descent when there occurred to him a thought that brought a grin to his savage lips--a thought that was born of the name the Waz-don had given him--Tarzan-jad-guru--Tarzan the Terrible--and a recollection of the days when he had delighted in baiting the blacks of the distant jungle of his birth. He turned back into the cave where lay the dead body of In-tan. With his knife he severed the warrior's head and carrying it to the outer edge of the recess tossed it to the ground below, then he dropped swiftly and silently down the ladder of pegs in a way that would have surprised the Kor-ul-lul who had been so sure that he could not climb. At the bottom he picked up the head of In-tan and disappeared among the shadows of the trees carrying the grisly trophy by its shock of shaggy hair. Horrible? But you are judging a wild beast by the standards of civilization. You may teach a lion tricks, but he is still a lion. Tarzan looked well in a Tuxedo, but he was still a Tarmangani and beneath his pleated shirt beat a wild and savage heart. Nor was his madness lacking in method. He knew that the hearts of the Kor-ul-lul would be filled with rage when they discovered the thing that he had done and he knew too, that mixed with the rage would be a leaven of fear and it was fear of him that had made Tarzan master of many jungles--one does not win the respect of the killers with bonbons. Below the village Tarzan returned to the foot of the cliff searching for a point where he could make the ascent to the ridge and thus back to the village of Om-at, the Kor-ul-JA. He came at last to a place where the river ran so close to the rocky wall that he was forced to swim it in search of a trail upon the opposite side and here it was that his keen nostrils detected a familiar spoor. It was the scent of Pan-at-lee at the spot where she had emerged from the pool and taken to the safety of the jungle.
