For a moment Ed was tense with the thought of precious time possibly wasted, chasing off to the Red Planet, when perhaps he should be trying to hunt down the perpetrators of offenses to a new biology--in vitaplasm. He knew that time remained still desperately short, with nuclear hell building up. But a choice had been made, and he sensed that it was the best one. Ed and Barbara went to see Les Payten that morning. He lay in a bed, his body encased in an armor of plastic, under which fluids circulated. He had mended enough to listen and speak. Ed partly explained his intentions. About them, Les showed a mixture of a sick man's insight and weariness: "I hope we'll see each other again, Ed. And that the world will still be around. And that you won't be changed too much--strong, weak, big or little. Because I've got things figured out _for me_ at last, Ed. Granger is right, as far as I am concerned. I was a romantic kid, but now I've had enough! The stars are still farther out of reach than we realize. Got to fight the murdering Phonies and all of the vitaplasm menace, no matter what. Because there never was a menace like it--not to me." Les grinned wanly. "So long, pals." In a park, some hours later, Barbara and Ed walked in the beautiful dusk, while the arch of silvery murk that had been Luna masked a few of the first stars. Something with long webbed wings was visible in silhouette against it for an instant--another creature that never existed before. It added a chill to their low mood. Ed was thinking that he must say goodbye to Barbara, too, very soon, and to all the chaotic wonder and charm that was Earth. Earth maybe in its last days. Barbara said, "I wish I were going along, Eddie." "So do I. Babs, go out to the asteroids. Like my mother. It's safer there." "I _meant_ my wish, Ed," Barbara protested earnestly. "Of course, a girl is still sometimes rated as a nuisance that a man has to take extra pains to look after--no companion for one to concentrate on the dangers ahead. Maybe it's true." He looked at her sharply and gulped hard. But gay little bells seemed to tinkle in his head. "Maybe a lot of things," he commented. "But I think you, as much as anybody, know what we're up against. Possible death, of course, which could be permanent. Or some fantastic loss or change of identity. How can we guess just what? If you can take all that mystery and hardship, too--well, I won't say no. Maybe if you were Mrs. Ed Dukas we could have Bronson provide your tickets to Mars." Her smile came out, like the sun. "You're heartlessly matter-of-fact and unromantic, Ed," she told him. He drew her into the shadow of a tree. A couple of minutes later, when he released her, they both looked dazed--as though, crazy as life was, it still could be heaven. She was beautiful. He'd never seen anyone so beautiful. Fifteen hours later they were aboard the _Moon Dust_. V
