"Unfortunately, Professor Farkas has just perfected the time transmitter. Those government scientists are so infernally officious--always inventing such senseless things. It's supposed to be hush-hush, but you know how news will leak out when one is always desperate for a fresh topic of conversation." Anyhow, Raymond went on to explain, Conrad had bribed one of Farkas' assistants for a set of the plans. Conrad's idea had been to go back in time and "eliminate!" their common great-grandfather. In that way, there would be no space-drive, and, hence, the Terrestrials would never get to the other planets and oppress the local aborigines. "Sounds like a good way of dealing with the problem," Martin observed. Raymond looked annoyed. "It's the _adolescent_ way," he said, "to do away with it, rather than find a solution. Would you destroy a whole society in order to root out a single injustice?" "Not if it were a good one otherwise." "Well, there's your answer. Conrad got the apparatus built, or perhaps he built it himself. One doesn't inquire too closely into such matters. But when it came to the point, Conrad couldn't bear the idea of eliminating our great-grandfather--because our great-grandfather was such a _good_ man, you know." Raymond's expressive upper lip curled. "So Conrad decided to go further back still and get rid of his great-grandfather's father--who'd been, by all accounts, a pretty worthless character." "That would be me, I suppose," Martin said quietly. Raymond turned a deep rose. "Well, doesn't that just go to prove you mustn't believe everything you hear?" The next sentence tumbled out in a rush. "I wormed the whole thing out of him and all of us--the other cousins and me--held a council of war, as it were, and we decided it was our moral duty to go back in time ourselves and protect you." He beamed at Martin. The boy smiled slowly. "Of course. You had to. If Conrad succeeded in _eliminating_ me, then none of you would exist, would you?" Raymond frowned. Then he shrugged cheerfully. "Well, you didn't really suppose we were going to all this trouble and expense out of sheer altruism, did you?" he asked, turning on the charm which all the cousins possessed to a consternating degree. * * * * * Martin had, of course, no illusions on that score; he had learned long ago that nobody did anything for nothing. But saying so was unwise. "We bribed another set of plans out of another of the professor's assistants," Raymond continued, as if Martin had answered, "and--ah--induced a handicraft enthusiast to build the gadget for us." _Induced_, Martin knew, could have meant anything from blackmail to the use of the iron maiden. "Then we were all ready to forestall Conrad. If one of us guarded you night and day, he would never be able to carry out his plot. So we made our counter-plan, set the machine as far back as it would go--and here we are!" "I see," Martin said.
