"One of Getty's men."

"Doc Pomposity?"

"That's right. Getty's not fully under control. His unconscious and natural wish not to kill Alan made him send a man out with an automatic, rather than a grenade pistol. But he was conditioned enough to feel that Alan was dangerous to us and he at least made a stab at assassination. Then before he could do it again, we got to him and told him we were going to 'convert' you."

All this while he had been twisting and turning the disk, making practice runs and dives; the control rooms, floated within the hull and leveling off no matter what direction the great saucer took, vibrated slightly and continuously. It was almost like being in the hold of a sailing ship.

Rob said, "I suppose the curious construction of your skeletons and muscular development helps you stand the motion and the acceleration of the disks?"

"That's right. Alan and Win can stand it too, especially since they feel no pain of any sort. But we haven't started going fast yet—I haven't put it above five hundred. When we hit four thousand—that's m.p.h.—I'm afraid you'll die, you three." Mac scowled unhappily. "I hope you realize I don't want to kill you? In the first place, I'd like to have you on my side, because we both have a score to settle with the hounds who bombed your cities. I would have slain Mariner out of hand, slain him as he slew poor Grady when he had him helpless in that chair, but luckily he got his in the fight. I haven't any wish to kill off my potential army, but the speed of an air battle will do it. And I'm going to be in some fights before long."

Alan, strapped to his chair, was leaning over toward Mac as far as he could. Now he said, "By heaven, you haven't any pores in your skin!"

"I was afraid you'd notice that before. I had a fantastic yarn cooked up to explain it. That's right, pal; Grady and me, and all the rest of us, haven't any sweat glands or pores or tear ducts. There are other little differences too, but they don't cut any ice. The differences notwithstanding, we are human. Not strictly Earthtype human, I suppose, but human nonetheless." He brooded over his controls, as the disk roared silently through the sky. "I like you all, too, dammit. I don't want to kill you. I think I'll chance another ten minutes and set you down.

"I must be getting soft in my middle age," he added with a wry smile. "Chancing the loss of a world for three idiot kids. Oh, well. What the hell. A gallant gesture will maybe pay off in the long run."
