"Pay no attention to the dogs," he commanded sharply. "Give these three a taste of the whip before the flayers rip the skins from their bodies. Begin with the girl." A heavy-featured man in a black tunic stepped up to Diana, pulling the lash of a heavy whip through his hands to test its suppleness. Before he could strike there came a sudden interruption. A small car had been speeding down the incline from the tunnel entrance and now a gilded officer of the invaders leaped out and came running across the Plaza. "Great news, oh Xylon and nobles of Gral-Thala!" he shouted. "One of our patrols has captured a great force of outlaw warriors and their insect allies, who were moving in to raid our nearer caves. Some more Earthlings are with them!" "Good, by Gorton!" exulted Xylon. "We will delay the execution of these three till the others are here to see it." Larry's last hope was gone. He had remembered Ripon's promise to come after them if they had not returned quickly, and in the back of his mind had been the thought that the doughty scientist might yet accomplish a rescue in some way. Now that hope had vanished. He sighed, and beside him Diana sagged visibly in her bonds. "Guess it's the end," she said. "Good bye, Larry!" XVI From where he stood on the scaffold, Larry could see a number of the big transport cars coming down the incline. They were crowded with prisoners and guards, and he caught the gleam of the hard brown shells of Insect-men. Once unloaded from the cars, they all formed up in columns and came quickly across the Plaza. Behind the front rank of guards Larry saw Ripon, and some of the men from the _Sky Maid_, and many whom he recognized as leaders among the Lunarians of the Lost Caverns. It was all over now. The prisoners trudged along like beaten men, utterly disheartened although they were but thinly guarded. The nobles grouped on the temple steps were laughing loudly, all their nervousness of a moment ago gone before the reassurance of this victory. Then, as the prisoners were halted in the Plaza directly before the double line of soldiers that guarded the temple, an officer beside Xylon leaned forward to point down at the commander of the patrol that was bringing in the prisoners. "That man wears the insignia of an Ensign of the first rank," he shouted, "but there is no such man in the ranks of our officers! There is treachery here!" Before the man's words had died away, Crispin Gillingwater Ripon had whipped a ray-gun out from under his cloak and smashed the officer's chest into a charred pulp with the deadly blast of the rays.
