A scream, high and wild, from Naida released Kirby from his trance of horror. He leaped off the corpse, and smashed a suddenly presented skull like an egg shell. Momentarily he saw Naida, too terrified to fire, staring at the open trapdoor. Kirby felled two apes and felt their blood on his arms. "Ivana!" he yelled. "Help Naida, for God's sake!" An answering shout, not from Ivana alone but from many girls, encouraged him, and he swung his club with a speed and force which would let nothing stand before him. But then another scream from Naida rang in his ears. "Naida!" he shouted. "It's all right! We're coming!" He knew, though, that it _wasn't_ all right. Fighting like a maniac, he opened another lane down which he glimpsed her. Fighting still, in a last terrific effort to force his way down the lane to her side, he saw the black opening gape at her feet; and, as Naida screamed again, a dozen hairy arms reached it at once, twisted the empty rifle out of her hands, and lifted her shining body as if it had been a feather. Shouts and murderous fire were coming from the other girls, and Kirby swung his club as never before. But even as he fell upon the last two or three apes which kept him away from Naida, those who had snatched her, bolted down the steps. Kirby was left with the memory of Naida's great eyes fixed upon his, fear-filled, beseeching his protection. In a second, the ponderous trapdoor crashed into place, and she was gone. CHAPTER XI Dazed and grief-stricken, Kirby stood in the bloody, corpse-filled nave of the temple, surrounded by thirty-two girls whose faces were blanched and most of whose eyes were tear-bright. The fight was over, and they were assembled to decide what must be done, but for a time no one spoke. Gaining the trapdoor just as it was pinioned from beneath, Kirby had torn at it with bare hands. But that had been hopeless. Then he had begun to fight again. But that had been hopeless also. With howls and screams they started to retreat, and it had not taken Kirby long to find out that every part of their raid had been carefully planned, even to this retreat under fire. Straight into the damp black tunnel which led away from the corridor behind the altar, the ape-men had leaped. And Kirby, in hot pursuit, had heard the Duca's voice driving them on. Too much the soldier to follow in that darkness where the Duca knew every foot of the way, and he knew nothing, Kirby had seen that he must go back to the girls and take stock. Now he looked at the strewn ape corpses, smelled the corrosive reek of burned powder, and tried to put aside his grief. "The Duca," he said at last, "must have been planning this with the apes ever since the first morning in the castle." Ivana, Naida's sister, nodded. "The Duca brought the ape-people here, kept them in the tunnel, and then herded them back when their work was done. I suppose it was one of the caciques who opened the door when the time was right."
