The intruder grinned wolfishly at him. "Pay no attention to Little Miss Sacktime over there, Forrester. You go right ahead and try it! All I need is an excuse to vaporize you. Just one tiny little excuse--and I'll do the job so damn quick, your head won't even have time to start swimming." He set himself. "Go on. Let's see your stuff, Forrester." Forrester's arm came down, without his being aware of it. There was only room in his mind for one thought. The intruder had called him Forrester. Where had he gotten the name? And, for that matter, how had he seen the two of them in the darkness? While the questions were still spinning in Forrester's mind, Kathy threw herself forward between him and the stranger. "Ares!" she screamed. "You stupid, jealous idiot! Get some sense into that battle-scarred brain of yours! Are you completely crazy?" "Now you listen to me--" the stranger began. "Listen, nothing! If you want to pick a fight, do it with me--I can fight back! But if you lay a hand on Forrester, we'll never find another--" The stranger reached out casually and clamped one huge paw over her mouth. "Shut up," he said, almost quietly. He glanced at Forrester and went on, in the same tone: "Don't give away everything you've got, chum." A second passed and then he took the hand away. Kathy said nothing at all for a moment, and then she nodded. "All right," she said. "You're right. We shouldn't be losing our tempers just now. But I didn't start--" "Didn't you?" the stranger said. Kathy shrugged. "Well, never mind it now." She turned to Forrester. "You know who we are now, don't you?" Forrester nodded very slowly. How else could the man have come through the cordon of Myrmidons and seen them in the darkness? How else would he have dared to face up to Dionysus--confident that he could beat him? And how else could all this argument have gone on without anyone hearing it? For that matter, why else would the argument have begun--unless the stranger and Kathy were-- "Sure," he said, as if he had known it all along. "You're Mars and Venus." He could feel cold death approaching. CHAPTER TEN William Forrester sat, quite alone, in the room which had been given him on Mount Olympus. He stared out of the window, a little smaller than the window in Venus' rooms, at the Grecian plain far below, without actually seeing. There was no vertigo this time; small matters like that couldn't bother him. The whole room was rather a small one, as Gods' rooms went, but it had the same varicolored shifting walls, the same furniture that appeared when you approached it. Forrester was beginning to get used to it now, and he didn't know if it was going to do him any good.
