She waggled the extremities and waited as if for the signal to travel through the nerves. "Nope," she said finally. "Can't feel anything broken. Would have been if I'd tried to stand." She moved back to get a better view of the robot. "That's throwing my weight around," she said with satisfaction. "At the right time in the right way. The secret's timing. And I must say you took the cue well." Her laughter rolled through the ship.

"I didn't have anything to do with the gravity," said Docchi.

"Who? Jordan—no, he's just getting up."

"Nona," said Docchi. "She was the only one who wasn't doing anything else. She saw what had to be done and got to it before I did. But I can't figure out how she got so much gravity."

"Ask her," said Anti.

Docchi grimaced, limping into the control room, followed by Anti and Jordan. Nona was at the gravity panel, her face pleasant and unconcerned.

The unprecedented power of the gravity field could be accounted for, of course. The ship was old and had seen much use. Connections were loose or broken and had somehow crossed, circuiting more power into the gravity generator than it was designed for. Miraculously it had held up for a brief time—and that was all there was to it. And yet the explanation failed to be completely satisfactory. "I wonder if you had anything to do with it," he said to her. Nona smiled questioningly.

"Had to, didn't she?" said Jordan. "She was the only one who could have turned it on."

"Started it, yes. Increased the power of the field, I don't know," said Docchi. He outlined what he thought had taken place.

"That sounds logical," agreed Jordan. "But it doesn't matter how it was done. Gravity engineers would find it interesting. If we had time I'd like to see how the circuits are crossed. We might discover something new."
