"Yes!" Once more, Colonel Lubintsev smiled like a little boy with great fun in store. "The possibilities of your device are as infinite as the universe! Think of the enormous help to the people of your nation, for example, if they could draw on machine tools and equipment from such alternate places as the one you have just left." Colonel Lubintsev waved his cigarette. "Or if, when the Americans attack us, we can transport bombs from a world where the revolution is an accomplished fact, and have them appear in North America in this." Professor Kempfer sat up in bed. "Marthe! Marthe, why have you done this to me?" "Hush, Jochim," she said. "Please. Don't tire yourself. I have done nothing to you. You will have care, now. We will be able to live together in a nice villa, and you will be able to work, and we will be together." "Marthe--" She shook her head, her lips pursed primly. "Please, Jochim. Times have changed a great deal, here. I explained to the Colonel that your head was probably still full of the old Nazi propaganda. He understands. You will learn to see it for what it was. And you will help put the Americans back in their place." Her eyes filled suddenly with tears. "All the years I went to visit your grave as often as I could. All the years I paid for flowers, and all the nights I cried for you." "But I am _here_, Marthe! I am here! I am not dead." "Jochim, Jochim," she said gently. "Am I to have had all my grief for nothing?" "I have brought a technical expert with me," Colonel Lubintsev went on as though nothing had happened. "If you will tell him what facilities you will need, we can begin preliminary work immediately." He rose to his feet. "I will send him in. I myself must be going." He put out his cigarette, and extended his hand. "I have been honored, Doctor Professor Kempfer." "Yes," Professor Kempfer whispered. "Yes. Honored." He raised his hand, pushed it toward the colonel's, but could not hold it up long enough to reach. It fell back to the coverlet, woodenly, and Professor Kempfer could not find the strength to move it. "Goodbye." He heard the colonel walk out with a few murmured words for Marthe. He was quite tired, and he heard only a sort of hum. He turned his head when the technical expert came in. The man was all eagerness, all enthusiasm: "Jochim! This is amazing! Perhaps I should introduce myself--I worked with your counterpart during the war--we were quite good friends--I am Georg Tanzler. Jochim! How _are_ you!" Professor Kempfer looked up. His lips twisted. "I think I am going away again, Georg," he whispered.
