Narina smiled, "But in the right direction?"
"Okay, lady, you win."
"Also," she pointed out, "it gives me something to do."
"Why not take some time to think of what we do next?"
"Not a chance," she replied.
He looked at her quizzically. "Supposing we do think of some answer," she said slowly. "Remember that we are still surrounded by the enemy; I'd rather have nothing to tell when, as, or if we are captured."
He nodded. "Against a coldly rational and logical machine, that would automatically eliminate one of the all too few possible answers, wouldn't it?"
"Sure would. About the only thing that the machine will ever try twice are those things that work very well and which it has reason to believe will continue to do so. But give it one idea that might work against it and you can wager that a foolproof defence will be set up instantly."
"So we keep our minds blank—what is it, Narina?"
"Just on the horizon—might be either a migratory flight of birds or a fleet of aircraft."
