Sax considered this. The mechanisms of memory were still very poorly understood, but no doubt something crude could be applied to the areas they knew were involved. Fast MRI, point-specific ultrasound, who knew what. It would surely be dangerous, however. . . .

“Well?” Phyllis said.

He stared at her smile, so angry and triumphant. A sneer. Random thoughts flickered through his mind, images without words: Desmond, Hiroko, the kids in Zygote shouting Why, Sax, why? He had to hold his face steady to keep it from revealing his dislike for her, suddenly pouring through him in a wave. Perhaps this sort of distaste was what people called hatred.

After a time he cleared his throat. “I suppose I’d rather just tell you.”

She nodded firmly, as if this was the decision she would have made herself. She looked around: the whole restaurant was empty now, the waiters sitting at one table, nursing glasses of grappa. “Come on,” she said, “let’s go to my offices.”

Sax nodded and rose stiffly. His right leg had gone asleep. He limped after her. They said good-night to the mobilizing waiters and left.

They got into the elevator, and Phyllis punched the button for the subway level. The door closed and they dropped. In an elevator again; Sax took a deep breath, then jerked his head down as if to look at something unusual on the control panel. Phyllis followed his gaze and with a jerky motion he slugged her on the side of the jaw. She crashed into the side of the elevator and collapsed in a heap, dazed and breathing in gasps. The two middle knuckles of his right hand hurt horribly. He hit the button for the floor two above the subway, which had a long passageway through Hunt Mesa, lined with shops that would be closed at this hour. He grabbed Phyllis by the armpits and hauled her up; she was taller than him, loose and heavy, and when the elevator door opened, he prepared himself to shout for help. But no one stood outside the door, and he pulled one of her arms over his neck and dragged her over to one of the little carts that sat by the elevator for the convenience of people who wanted to cross the mesa quickly, or with a load. He dumped her onto the backseat and she groaned, sounding as if she was coming to. He sat down ahead of her in the driver’s seat and stomped the accelerator pedal to the floor, and the little vehicle hummed down the hallway. He found he was breathing hard, and sweating.
