Alan fired his last volley, stood there in despair. He had run out of ammunition. The cobalt outer skin of the bomb shook, spread apart, fell away in two equal hemispheres. The technicians were plunging down the scaffold, Alan right behind them. They tumbled inside the moon tank. Laura didn't have to be told. The tank bounced away at full speed. Behind them, a brilliant flash lit the lunar sky. For a moment, Alan could see the hydrogen bomb streaking Earthward, a silver speck against the blackness. Then it was gone. It was a vast trigger now, and nothing more. Harmlessly, it would explode in the Pacific Ocean, like dozens of tests which had been conducted there. The Outworlds would agree to Equal Union now. Alan knew that. The technician had told him. They had never liked the war. They were ready to rally behind his name. There would be some ugliness between Earth and the Outworlds for a time, because of what had almost happened. But it would pass. The Lunar Mines dome loomed ahead of them. The domelock opened to admit them. "I wish we were inside already," Laura said, "where there's some air." "What for?" Alan asked her. "So I can take off this helmet and kiss you." Nothing would suit Alan better. Now, at last, they were inside. He took off his helmet.
