"Then why take even that risk?" Arlene asked. "Wouldn't it be better to destroy the projector now--to leave things as they are--rather than offer him a weapon which would reduce us all to helpless chattels again?" Weldon shook his head. "Arlene, we can't leave things as they are! Neither can the rogue. You know that really--even though you refuse to admit it to yourself at the moment." "I ... what do you mean?" * * * * * "This year," Weldon said patiently, "we have the diex projector. What will we have five years from now when diex energy has been more fully explored? When the other fields of knowledge that have been opened in recent years begin to expand? We could, perhaps, slow down those processes. We can't stop them. And, at any point, other unpredictable weapons may emerge ... weapons we might use against the rogue, or that he might use against us. "No, for both sides the time to act is now, unless we're willing to leave the future to chance. We aren't; and the rogue isn't. We've challenged him to determine whether he or mankind will control this planet, and he's accepted the challenge. It amounts to that. And it's very likely that the outcome will have become apparent not many hours from now." Arlene shook her head but said nothing. Dr. Lowry asked, "Ferris, exactly what is _our_ role in this situation supposed to be?" "For the next few hours," Weldon said, "you'll be instructing me in the practical details of operating the projector. I've studied your reports very carefully, of course, and I could handle it after a fashion without such help. But that isn't good enough. Because--as the rogue knows very well--we aren't bluffing in the least in this. We're forcing him to take action. If he doesn't"--Weldon nodded at the polished hardwood box on the table before Dr. Lowry--"one of our telepaths presently _will_ be placed before that instrument of yours, and the rogue will face the possibility of being flushed into view. And there is no point on the globe at this moment which is more than a few minutes' flight away from one of our strike groups. "So he'll take action ... at the latest as soon as the order is given to move our telepath to the Cleaver Project. But you two won't be here when it happens. You're not needed for that part, and while we've been talking, the main project conduit has been shunted from our university exit here to a security island outside the area. You'll move there directly from the project as soon as you finish checking me out, and you will remain there until Operation Rogue is concluded. "And now let's get busy! I think it would be best, Ben, if I assumed Arlene's usual role for a start ... secondary operator ... and let you go through the regular pattern of contacts while I look on. What do you say?" * * * * *
