"I wish he hadn't been so bashful," Harkness added. "If he had come out and showed himself he would have saved us a lot of trouble." But Harkness stepped forward and patted the black shoulder that quivered with joy beneath his touch. "Good boy, Towahg!" he told the grinning ape-man. Monkey-like, Towahg had to imitate, and this time he gave a reproduction of his own acts. He wriggled toward the entrance of the passage, peered around the edge, and seemed to see something that made him draw back. Then he fitted an arrow to his bow and springing upright, let it fly. So realistic was the performance that Chet actually expected to see another enemy transfixed, but the squat figure of Towahg was doing a dance of victory beside the prostrate figure of the first and only victim. Chet reached out with one long arm and swung the exulting savage about. He heard Herr Kreiss expressing his opinion in accents of disgust. "Ugly little beast!" Kreiss was saying. "And murderous!" There was no time to lose: the sound of scrambling bodies was coming nearer from the dark pit beyond. Yet, even then, Chet found an instant to defend the black. "Damned lucky for us that he is a murderer!" he told Kreiss. Then to Towahg: "Listen, you little imp of hell! You don't know more than ten words, but get this!" Chet was standing where the Earth-light struck upon him; he pointed into the dark where the sounds of pursuit grew loud, and he shook his head and screwed his features into an expression that was supposed to depict fear. "No! No!" he said. He dragged the savage forward and pointed cautiously to the milling horde below, and repeated, "No! No!" Then he included them all in a wave of his hand and pointed back and out into the night. And Towahg's unlovely features were again twisted into what was for him a smile, as he grunted some unintelligible syllables and motioned them to follow. * * * * * It had taken but an instant. Towahg was scurrying in advance; he sped like a shadow of a passing cloud, and behind him the others followed, crouching low in the shelter of the deep-cut step. No figures were below them at the rear of the pyramid, and Chet reached for one of Diane's arms, while Harkness took the other. Between them they held her from falling while they followed the dark blur that was Towahg leaping noiselessly down the long slope. No time for caution now. The savage ahead of them leaped silently; his flying feet hardly disturbed a stone. But beneath them, Chet felt a small landslide of rubble that came with them in their flight. And above the noise of their going came a sound that sped them on--the rising shout of wonder from the unseen multitude in front, and a chorus of animal cries from the pyramid's top.
