A woman's voice rang out. "Watch out, Professor!"

Seldon sighed and regarded the large young men he faced. He didn't know if he could do it, if his reflexes were quick enough, his muscles sturdy enough, even given his prowess at Twisting.

One goon was approaching him, overconfidently of course. Not quickly, which gave Seldon a little of the time his aging body would need. The goon held out his arm confrontationally, which made it easier.

Seldon seized the arm, whirled, and bent, arm up, and then down (with a grunt-why did he have to grunt?), and the goon went flying through the air, propelled partly by his own momentum. He landed with a thump on the outer edge of the platform, his right shoulder dislocated.

There was a wild cry from the audience at this totally unexpected development. Instantly an institutional pride erupted.

"Take them, Prof!" a lone voice shouted. Others took up the cry.

Seldon smoothed back his hair, trying not to puff. With his foot he shoved the groaning fallen goon off the platform.

"Anyone else?" he asked pleasantly. "Or will you leave quietly?"

He faced Namarti and his five henchmen and as they paused irresolutely, Seldon said, "I warn you. The crowd is on my side now. If you try to rush me, they'll take you apart. Okay, who's next? Let's go. One at a time."

He had raised his voice with the last sentence and made small come-hither motions with his fingers. The crowd yelled its pleasure.

Namarti stood there stolidly. Seldon leaped past him and caught his neck in the crook of his arm. Students were climbing onto the platform now, shouting "One at a time! One at a time!" and getting between the bodyguards and Seldon.
