Countless other rockets would fly out of it, each directed, each exploding and casting out its deadly sprays and gases of the G-agent. "Within an hour," Morgenson said, "after the rocket hits, there won't be a bug, a germ, a piece of lichen left alive. Unless somebody sends it there, there won't be anything alive on Mars again for a long time." "I'd still like to know what kind of life it is," Schauffer said. Michelson looked at the floor. "Now we'll never know." "But we'll stay alive to speculate about it, and some day maybe they'll figure how to get a man across space. And then we'll know what died up there." There was a chance, Michelson knew, but a very slim one, that something might go wrong. The rocket might crash on the Earth somewhere. But no one else probably even dared to think about it. None of them were as old nor as tired as Michelson. A lot of people would die. Just in case the Martians might have something in the way of gases as deadly as the G-agent, the population had been supplied with hypos of antidote, gas masks, and suiting. But still, so many people would die. However such a thing was very highly improbable. They drank again. Engstrand put his hand on Michelson's bowed shoulders. "Again you've done a magnificent job, old friend." His voice was low. "Three weeks ahead of schedule. That time advantage may have saved us all. God knows what the Martians are getting ready to send now!" "One thing we can be thankful for," Schauffer said. "No spies. No worry about security, no saboteurs. Of course the Martians are lucky too—or were—in that respect." He looked thoughtfully into his glass. "The Martians did us a favor really. They created world unity. A psychologist couldn't have predicted it. But think of that—since the war with Mars, no human being has ever tried to sabotage anything directed at defeating the Martians!" "It's natural enough. This time it's humans against—well—God knows what! But nothing human." Engstrand poured himself another drink. "No human being has had anything to identify with in the enemy's camp. You're right, Major. In a way, the Martians did us a favor. And now we'll do them one—one last favor. They're too damn evil to live, and they'll sure be glad, somewhere in their guts, to be finished off!" Schauffer turned to Michelson, and grinned. "Where's Mary?"
