"Make it snappy," Walton said. His watch read 1429. Only twenty minutes had passed since he had gone down there. A grimy sheet of paper was thrust under his nose. He read it: _Hello Walton, this is McLeod. Happy to report that experimental ship X-72 is returning home with all hands in good shape, after a remarkable one-year cruise of the galaxy. I feel like Ulysses returning to Ithaca, except we didn't have such a hard time of it._ _I imagine you'll be interested in this: we found a perfectly lovely and livable world in the Procyon system. No intelligent life at all, and incredibly fine climate. Pity old FitzMaugham couldn't have lived to hear about it. Be seeing you soon. McLeod._ Walton's hands were still shaking as he pressed the actuator that would let him back into his office. He would have to call another meeting of the section chiefs again, to discuss the best method of presenting this exciting news to the world. For one thing, they would have to explain away FitzMaugham's failure to reveal that the X-72 had been sent out over a year ago. That could be easily handled. Then, there would have to be a careful build-up: descriptions of the new world, profiles of the heroes who had found it, etcetera. Someone was going to have to work out a plan for emigration ... unless the resourceful FitzMaugham had already drawn up such a plan and stowed it in Files for just this anticipated day. And then, perhaps Lamarre could be called back now, and allowed to release his discovery. Plans buzzed in Walton's mind: in the event that people proved reluctant to leave Earth and conquer an unknown world, no matter how tempting the climate, it might be feasible to dangle immortality before them--to restrict Lamarre's treatment to volunteer colonists, or something along that line. There was plenty of time to figure that out, Walton thought. He stepped into his office and locked the door behind him. A glow of pleasure surrounded him; for once it seemed that things were heading in the right direction. He was happy, in a way, that FitzMaugham was no longer in charge. Now, with mankind on the threshold of-- Walton blinked. _Did I leave that file drawer open when I left the office?_ he wondered. He was usually more cautious than that. The file was definitely open now, as were the two cabinets adjoining it. Numbly he swung the cabinet doors wider, peered into the shadows, groped inside. The drawers containing the documents pertaining to terraforming and to McLeod's space drive seemed intact. But the cabinet in which Walton had placed Lamarre's portfolio--that cabinet was totally empty! _Someone's been in here_, he thought angrily. And then the anger changed to agony as he remembered what had been in Lamarre's portfolio, and what would happen if that formula were loosed indiscriminately in the world. IX The odd part of it, Walton thought, was that there was absolutely nothing he could do.
