"It won't mean much of a delay," I went on. "Ravenhurst can still have his big splash on Earth."

We herded Brentwood into the lounge and bound him to a chair. Then I said: "McGuire?"

"Yes, sir?"

"We're changing course. Return to Ceres."

And McGuire said: "I'm sorry, sir; I cannot obey any orders except those of Mr. Daniel Oak."

I just stood there for a long minute. "I am Daniel Oak," I whispered. But I was fairly certain that the declaration would do me no good whatever.

I was right. "No, sir. You are not Mr. Oak." McGuire is always polite to anyone who speaks to him, even if he doesn't regard that person as human.

"McGuire," I said patiently, "can you see Mr. Oak? Is he on board?"

"Yes, sir. I perceive him seated on the starboard couch in the main lounge."
