"You look a bit dull," she said. She dug a box out of a travel-bag placed in a corner of the room. "Here," she said. "Put this on—left side."

"This" proved to be a magnificent sunburst decoration, a glittering diamond-encrusted star. He said, "What is it?"

"Grand Order of the United Worlds—a fine diplomat you are! I picked it up for you this afternoon before flying here. Just stick it on...." She came over, took it from him, pressed it firmly against his bolo till the suction grips caught hold.

He put his arms around her. She let him hold her a moment, then pushed clear in the immemorial gesture of women dressed for a party who do not want to have their grooming mussed. "Not now," she said. "We'll have plenty of time."

"Not for what's worrying me," he said. "Nina, I've got to put Giac through its paces in front of the whole world tomorrow. And I don't know what to ask it. I've got a blind spot where symbolic logic is concerned."

"Don't fret yourself," said the girl calmly. "I'm not worried about you. Not after what you've managed to do to all the other computers you've faced. Come on—we're having dinner with the president."

"Who the hell are you anyway?" he asked her bluntly. "You don't even look the same."

She laughed. "I should hope not," she told him. "After all, I could hardly grace the president's table as a mere UW secretary—or as a New Orleans top model. Come on!"

He went—and got his second shock when President Giovannini greeted Nina with a manner as close to obsequiousness as that professionally free-and-easy politician could muster. He said, "My dear Miss Norstadt-Ramirez. I do hope you'll forgive me for ordering such summary action this morning. If I'd had the slightest idea...."

"I was boiling," Nina told him. "I was just about ready to order Aetnapolitan to pull the props out from under you when the riots started. Then I blessed your shiny little head and came up here."
