"She wasn't feeling well," Michelson said. "I left her out at Lake House." He stood up. Quietly, he said. "Good-bye, gentleman. I'm going home, to Lake House. I'm tired." "Aren't you going to watch the rocket blast?" Michelson shook his head. "I think not." They all shook hands with Michelson. "Write us, will you, Mike," Engstrand said. "Let us hear from you often." "Of course," Michelson said. At the door he turned, an old man, stooped by years of devotion to more and more deadly chemicals. "If you need me, I'll still be at Lake House." He went out of the observation room and stood for a moment looking at the elevator that waited with an open mouth. He had always been with G-2. Back when they had started over again in the ruins of World War III he had been in charge of various space-going projects aimed at a quick defeat of the Eurasians, and this always included the latest complex developments in bacteriological warfare, and the use of liquid and atmospheric gases. He had sent the first New Era test rocket into space, the first one to the moon, the first ones to Mars. Instruments far in advance of the original telemetering and servomotor devices, had measured temperature, radiation, chemical makeup of atmosphere, minerals, various field effects, measured and catalogued all life, even to its cultural development, then sent back their measurements and evaluations on ultra-high-frequency to ground observers on Earth. He had sent out the first rockets with monkeys, rats, guinea pigs and birds to test the effects of alien conditions on living organisms. No human being had ever survived. They stopped trying. But the Martians had been carrying on a program much the same. They had been frightened. They had sent deadly rockets. The war had begun, a fantastic push-button operation between worlds millions of miles apart. This Earth rocket loaded with three tons of G-agent was what the UN hoped would be the last retaliatory gesture in a number of years of interspatial bickering. For it was also evident now that no Martian could get across space to Earth. Michelson sighed, stepped into the elevator and started home. Home to rest, fish, lie in the sun. Home to Mary who kept him occupied and entertained in his loneliness. But Mary had not been ill. She had not stayed at Lake House
