And then McGuire's voice—human, masculine, and not distorted at all by the reproduction system, but sounding rather stilted and terribly logical: "I remember, Jack. The memory banks of my previous activations are available."

"All of them? Can you remember everything?"

"I can remember everything that is in my memory banks."

The girl's voice rose to a wail. "But you don't remember! You always forgot things! They took things out each time you were reactivated, don't you remember?"

"I cannot remember that which is not contained in my memory banks, Jack. That is a contradiction in terms."

"But I was always able to fix it before!" The tears in her eyes were audible in her voice. "I'd tell you to remember, and I'd tell you what to remember, and you'd remember it! Tell me what's happened to you this time!"

"I cannot tell you. The information is not in my data banks."

Slowly, I got to my feet. Two gees isn't much, once you get used to it. The headache had subsided to a dull, bearable throb.

I was on a couch in a room just below the control chamber, and Jack Ravenhurst's voice was coming down from above. McGuire's voice was all around me, coming from the hidden speakers that were everywhere in the ship.

"But why won't you obey me any more, McGuire?" she asked.
