“A hospital is not the same as a prison,” Schroeder said. “They let you go if you sign a paper. Do you think I could stay in bed knowing you were doing this?” He gazed with wonderment at the plane under its bright lights. “Ingenious. Do you really think you can neutralize the reversal from the air?”

“We're going to try,” Karla said.

“We? You're not going on this mission? It might be dangerous.”

“You sound like Kurt. I'll tell you the same thing I told him. My family is responsible for this mess. It's my responsibility to help clean it up.”

Schroeder laughed. “You're Lazlo's granddaughter, without doubt. Stubborn, just like him.” He turned to Austin. “Take good care of her.”

“I promise,” Austin said.

Schroeder glanced at the bustling activity in and around the plane. “When do you expect to leave?”

“Tomorrow morning,” Austin said.

“This is one old dinosaur who knows when he's extinct,” Schroeder said. “I'll be at the hospital waiting for your call. Good luck.” He embraced Karla, shook hands with Austin and hobbled back to his car. They watched the car's taillights until they were out of sight, then Austin turned to Karla.

“We've got lots of work to do.”

She nodded. Walking arm in arm, they made their way toward the huge aircraft.

WHILE AUSTIN'S NUMA crew was in a frantic race to achieve the impossible, Tris Margrave was having no doubts about the imminent success of his project. Doubt was something foreign to him, and would never have entered his mind.

As the Polar Adventure plowed through the South Atlantic, he sat in his comfortable ergonomic chair behind a control panel built into the forward observation platform. His long fingers played over the controls like an organist in a great cathedral. He had started the dynamos as soon as the ship left port. Each generator was represented on the large computer monitor by a red symbol and number, which meant that it was active at a low level.

Red lines ran from the dynamos to the image of a cone. The cone was green except for its red point, indicating that a minimum amount of power was flowing into the huge coil lodged deep in the ship's hold. Margrave thought of it as the equivalent of idling a car motor.

On another screen, the console displayed a cutaway diagram of the earth that showed its layers. Special sensors in the ship's hull would be able to detect the electromagnetic penetration and the extent of ripple effect.

Gant had been on a tour of the ship talking with his security people. Ever the perfectionist, Gant wanted to be sure that when Margrave had outlived his usefulness he would be quickly disposed of. As he entered the observation platform, Gant smiled and said, “Not much longer?”
