"Please, madam, permit me to explain. A crumb is all I need. I can analyze the contents of the cake sufficiently well from that. Let me take for instance Cake Number 4, made from an excellent recipe, well baked. Martian granis flour, goover eggs, tingan-flavored salt, a trace of Venusian orange spice, synthetic shortening of the best quality. The icing is excellent, made with rare dipentose sugars which give it a delightful flavor. Unfortunately, however, the cake will not win first prize." An anguished cry rose from the audience. "Why?" "Through no fault of your own, dear lady. The purberries used in making the filling were not freshly picked. They have the characteristic flavor of refrigeration." "The manager of the store swore to me that they were fresh! Oh, I'll kill him, I'll murder him--" She broke down in a flood of tears. * * * * * Ronar said to the lady who had protested, "I trust, madam, that you will now have slightly greater confidence in my judgment." She blushed and subsided. Ronar went on with the testing. Ninety per cent of the cakes he was able to discard at once, from some fault in the raw materials used or in the method of baking. Eleven cakes survived the first elimination contest. He went over them again, more slowly this time. When he had completed the second round of tests, only three were left. Number 17 belonged to Mrs. Cabanis. Number 43 had been made by the man who argued with his wife. Number 64 was the product of the young bride, whom he had still not seen. Ronar paused. "My sense of taste is somewhat fatigued. I shall have to ask for a short recess before proceeding further." There was a sigh from the audience. The tension was not released, it was merely relaxed for a short interval. Ronar said to the chairman, "I should like a few moments of fresh air. That will restore me. Do you mind?" "Of course not, Mr. Ronar." He went outside. Seen through the thin layer of air which surrounded the group of buildings, and the plastic bubble which kept the air from escaping into space, the stars were brilliant and peaceful. The Sun, far away, was like a father star who was too kind to obliterate his children. Strange, he thought, to recall that this was his native satellite. A few years ago it had been a different world. As for himself, he could live just as well outside the bubble as in it, as well in rarefied air as in dense. Suppose he were to tear a hole in the plastic-- Forbidden thoughts. He checked himself, and concentrated on the three cakes and the three contestants. "You aren't supposed to let personal feelings interfere. You aren't even supposed to know who baked those cakes. But you know, all right. And you can't keep personal feelings from influencing your judgment. "Any one of the cakes is good enough to win. Choose whichever you please, and no one will have a right to criticize. To which are you going to award the prize?
