What she said to van Manderpootz was in tones too low for me to hear, and apparently too low for Carter's ears as well, else I should have heard her words through the attitudinizor. But both of us heard van Manderpootz's bellow in answer. "I don't care how the dictionary pronounces the word!" he roared. "The way van Manderpootz pronounces a word is right!" The glorious Lisa turned silently and vanished. For a few moments I watched her through Carter's eyes, but as she neared the laboratory door, he turned his attention again to van Manderpootz, and she was lost to my view. And as I saw the professor close his dissertation and approach me, I slipped the attitudinizor from my head and forced myself to a measure of calm. "Who is she?" I demanded. "I've got to meet her!" He looked blankly at me. "Who's who?" "Lisa! Who's Lisa?" There was not a flicker in the cool blue eyes of van Manderpootz. "I don't know any Lisa," he said indifferently. "But you were just talking to her! Right out there!" Van Manderpootz stared curiously at me; then little by little a shrewd suspicion seemed to dawn in his broad, intelligent features. "Hah!" he said. "Have you, by any chance, been using the attitudinizor?" I nodded, chill apprehension gripping me. "And is it also true that you chose to investigate the viewpoint of Carter out there?" At my nod, he stepped to the door that joined the two rooms, and closed it. When he faced me again, it was with features working into lines of amusement that suddenly found utterance in booming laughter. "Haw!" he roared. "Do you know who beautiful Lisa is? She's Fitch!" "Fitch? You're mad! She's glorious, and Fitch is plain and scrawny and ugly. Do you think I'm a fool?" "You ask an embarrassing question," chuckled the professor. "Listen to me, Dixon. The woman you saw was my secretary, Miss Fitch, seen through the eyes of Carter. Don't you understand? The idiot Carter's in love with her!" * * * * * I suppose I walked the upper levels half the night, oblivious alike of the narrow strip of stars that showed between the towering walls of twenty-first century New York, and the intermittent roar of traffic from the freight levels. Certainly this was the worst predicament of all those into which the fiendish contraptions of the great van Manderpootz had thrust me. In love with a point of view! In love with a woman who had no existence apart from the beglamoured eyes of Carter. It wasn't Lisa Fitch I loved; indeed, I rather hated her angular ugliness. What I had fallen in love with was the way she looked to Carter, for there is nothing in the world quite as beautiful as a lover's conception of his sweetheart.
