"Yes, of course—but we have to find a reason why they were in that part of Space and it has to be a nice one, I mean so that the Incognitans when they finally read the log won't hate them any more—"
"Maybe they were bravely defending their own planet by hunting down an interplanetary raider," I suggest.
Cray says it will take only the briefest contact with other planets to convince the Incognitans that interplanetary raiders can't and don't exist, modern planetary alarm and defense systems put them out of the question.
"That's all he knows," says B, "some interplanetary pirates raided Lizzie's father's farm once. Didn't they, Liz?"
"Yes in a manner of speaking, but they were bums who pinched a spaceship from a planet not many parsecs away, a sparsely inhabited mining world like my own which had no real call for an alarm system, so that hardly alters the argument."
"Well," says B, "the alarm system on Incognita can't be so hot or the observation ships could not have got in, or out, for that matter, unless of course they have some other gadget we don't know about."
"On the other hand," she considers, "to mention Interplanetary raiders raises the idea of Menace in an Unfriendly Universe again, and this is what we want to cancel out.
"These people," she says at last with a visionary look in her eye, "come from a planet which went isolationist and abandoned space travel; now they have built up their civilization to a point where they can build ships of their own again, and the ones on Gilgamesh have cut loose from the ideas of their ancestors that led to their going so far afield—"
"How far afield?" says Cray.
"No one will ever know," I point out to him. "Don't interrupt."
