“Make up your mind.”

“How can I?” He gestured. “I have both memory-tracks grafted inside my head; one is real and one isn’t but I can’t tell which is which. Why can’t I rely on you? They haven’t tinkered with you.” She could do this much for him at least even if she never did anything else.

Kirsten said in a level, controlled voice, “Doug, if you don’t pull yourself together, we’re through. I’m going to leave you.”

“I’m in trouble.” His voice came out husky and coarse. And shaking. “Probably I’m heading into a psychotic episode; I hope not, but—maybe that’s it. It would explain everything, anyhow.”

Setting down the bag of groceries, Kirsten stalked to the closet. “I was not kidding,” she said to him quietly. She brought out a coat, got it on, walked back to the door of the conapt. “I’ll phone you one of these days soon,” she said tonelessly. “This is goodbye, Doug. I hope you pull out of this eventually; I really pray you do. For your sake.”

“Wait,” he said desperately. “Just tell me and make it absolute; I did go or I didn’t—tell me which one.” But they may have altered your memory-track also, he realized.

The door closed. His wife had left. Finally!

A voice behind him said, “Well, that’s that. Now put up your hands, Quail. And also please turn around and face this way.”

He turned, instinctively, without raising his hands.

The man who faced him wore the plum uniform of the Interplan Police Agency, and his gun appeared to be UN issue. And, for some odd reason, he seemed familiar to Quail; familiar in a blurred, distorted fashion which he could not pin down. So, jerkily, he raised his hands.

“You remember,” the policeman said, “your trip to Mars. We know all your actions today and all your thoughts—in particular your very important thoughts on the trip home from Rekal, Incorporated.” He explained, “We have a telep-transmitter wired within your skull; it keeps us constantly informed.”
