"Bind him? Isn't he going to run this thing?"

"No."

"You're going to, Carse?"

"Yes. I don't quite trust Dr. Ku. The asteroid's controlled on the same principles as a space-ship: I'll manage. Please hurry, Ban."

"M. S.?" he asked into the microphone. "You're there?"

"Yes. Carse? What's happened?"

"All's well, but I'm in a tremendous hurry: I've only got time, now, to tell you we're on the asteroid with Dr. Ku prisoner, and that I'm undertaking to transplant the coordinated brains into living human bodies.... What? Yes transplant them! Please, M. S.—not now: questions later. I'm calling primarily to learn whether you have any V-27 on hand?"

Eliot Leithgow, in his distant laboratory, paused before replying. When his voice sounded in the receivers again, it was excited.
