"He was transferred to XXX Base three days ago, right after he left your ship. Couldn't let him run around here for a while. Not after the trouble with your crew--somebody might recognize him. Besides, he already has another assignment there." "I think it was a pretty stupid thing," Maise grumbled. "He was so obvious. And suppose I hadn't warned him about it that night, or that I hadn't been there when the spore-poisoning idea came to a head among the crew? They might really have tried to get him outside the dome, or to get a spore culture inside. And then we'd all be sick or dead." "Not likely, sir," the SR Officer said with a polite, knowing smile. "You see, the aliens are presumably susceptible to their own bacteriological weapons. At least we think so from the way they went about it. They want our planets, and they didn't want to have to decontaminate them when they took them over. Besides, it's practically impossible to decontaminate an entire planet, anyway." "But we did it with Earth." "For morale purposes, Central Authority let it be known that they were able to decontaminate it, but what actually happened was that the spores lost their effectiveness within a few years of their original seeding. I'm surprised they didn't tell you that in the beginning--" He caught himself suddenly, then shrugged and smiled again. "Maybe you aren't supposed to be told," he continued without embarrassment. "It's sometimes hard for me to know about such things. You have no idea how confused the directives can get in an organization this large. Anyway, as you can see, your men couldn't have poisoned Frendon or themselves or anybody else with those spores. That's why we have been using that particular form of suggested violence in this unpleasant business. If, as you pointed out, something unexpected did happen, it would be absolutely harmless. Naturally," he added, "we wouldn't like to risk unnecessarily a professional actor with such a remarkably suitable physical appearance as Commander Frendon--even if the poor fellow doesn't have the slightest trace of psi ability." Maise gaped at him for a moment as he comprehended the careful, knowledgeable planning behind the ruse, much of which had not been explained to him before in his briefings. He said, "And I guess there is still a lot more about it that I don't know." The SR Officer nodded agreement. "Neither you nor I," he replied in bald understatement. "After all, there are some pretty intelligent men in charge of this last-ditch defense of our species, and they do keep a few of the more important things to themselves. For your own safety among your crew, I suggest that you keep this spore business equally secret." "I don't need your advice for that," Maise said with a low voice and a wry grin on his face. But the grin vanished as he stood up to go. He hesitated and shook his head uncertainly. "So that takes care of that," the SR concluded. "Now you're all set, aren't you?"
