He slumped weakly against the bulkhead, wiping at his forehead with the back of a shaking hand. "There were enough clues," he said hoarsely. And there had been, at that. _Tertium Organum_, A Key To The Enigmas Of The World, _was_ a key. Its author, Ouspensky, looked at the universe from a _different_ viewpoint. The small _u_ in unterzuyder meant that it was to be taken as a common noun. And certainly the conclusion that the map was made 50,000 years ago was itself an obvious clue! "We made our calculations on the assumption that the map had been made looking at the Solar System from the north--from the star Polaris, that is. It hadn't been. My ancestors drew the map from the unorthodox reference point of the Southern Cross. "From the underside. I turned the negative upside down and made a new map. Then I got right answers." "Very good," said Fayette. "The tricky Unterzuyders did live up to their name. _Didn't_ they, Ralph?" "Yes," he said shakily. The gun wavered. Fayette was blinking. "Ralph, do you love me?" "Yes...." "Are you being truthful? Will you always tell me the truth, the whole truth?" "Yes...." "That's a good boy. Please keep on giving my pet the right answers. Ralph, don't you know that if you freed the Unterzuyders I couldn't ever look at you again?" There were angry tears in her eyes. Unterzuyder suddenly remembered the time at the dance, when he had wiped away her tears. He should wipe them away now. He was weakening. He was an Unterzuyder. He should be strong. There was his duty.... "Fayette," he said hoarsely. "Stand back." Her chin came up. "Answer the question! Yes or no." "Yes." "Do you want to marry me?" "Yes, Fayette." Her mouth opened and closed. Suddenly her shoulders heaved and she shook her head blindly. The gun dropped to her side. "Oh, Ralph. I can't do it. I was going to ask you if you still wanted to go ahead with it. But I can't. I can't force you. You'll have to make up your own mind!" She turned away, hiding her face with one arm. Instantly, he leaped for her, tearing the gun from her hand. He looked at it where it lay black and ugly in his hands. He was seeing it very well, with his excellent Unterzuyder eyes. It slipped from his hand and fell to the floor. He let it lie, and took Fayette into his arms.
