Amusement was in Tollgamo's eyes and twitching at his thin grey lips. "So? You would join me, and still try to lie to me?" His gesture dismissed it. "We will talk of that some other time." For a moment he stood pondering. "That girl--that Peters' daughter," he added. "Rhool tells me she is very beautiful. Is that so?" There seemed a twinkle in his inscrutable eyes. "Yes," Allen agreed. "That is interesting. I must see for myself. I think perhaps I must protect her from the things that will happen tonight." Allen tensed inside. Did he mean that his attack upon the Arones would take place tonight? "The woman Garga will give you supper," Tollgamo added abruptly. From a ring on his finger a silent light-signal sprang across the room and through a small arcade doorway; and at once Garga appeared there. "Take him to my rest-room," Tollgamo said. "He is hungry. Give him food. I will send for him later." "Yes, Master." Then as Tollgamo moved away, lithe and silent as a great panther, with his padded soles soundless on the metal floor, he said quietly. "Your thoughts are very transparent, Earthman. But I think you can be of use to me." * * * * * In the small adjoining room, Garga brought Allen food. They ate it together. "What did he mean by things that will happen tonight?" Allen suddenly murmured. Garga had been sitting, staring at him with her slumbrous dark gaze. "The attack," she said. "And Peters doesn't know that?" "No." Her hand touched him. "I am trusting you." "Of course," Allen agreed. He recalled how Nereid's brother, Leh, as the spaceship landed, had gazed down at the inlet, across which workers were bringing things from a tunnel to the edge of the water. Leh had sucked in his breath as though with startled surprise. "The attack," Allen murmured. "Will it be upon the city of Arron?" "Yes--naturally. And the imbecile slaves there--they think they are going to help." Her grim grey face lighted with a smile. "That will be amusing; those imbecile workers causing bloodshed, making it so easy for us, when we get there." "Get there--how, Garga? By air?" Allen felt that Leh now was trying to get just such information as this; and he and Allen would escape--get to Arron and warn Peters. But evidently haste was necessary. By what Tollgamo said, he would be attacking perhaps within a few hours. "By air?" Garga echoed. "Oh no. By water." She leaned closer to Allen. A woman warrior. But the womanhood in her now was making her bosom rise and fall with her emotion at Allen's nearness. "Under the water," she murmured. "You see how clever we are? That is the last method of attack that the Arones think we will try. There are grottos beneath the city of Arron. Grottos with the sea in them. So that we shall come up that way, appearing all over the city at once." She chuckled. "They will not know there is to be any attack at all. Just trouble with the imbeciles. And suddenly we will be there among them!"
