Farradyne gave her hand a squeeze. "Done!" he glowed. Silently he wondered whether she were really cured. He looked at her, at the glow in her eyes and at the blush on her face, and he hoped so.

He slipped over the back of the pilot's seat and pushed down hard on the toggle bar. The weightlessness came, and the compressed springs of their seats tossed them up against the restraining straps. From below there came a moan, but beside him, Norma relaxed in full confidence and watched him work the controls with interest.

Two light years an hour ... Farradyne ran the Lancaster for exactly three hours and then cut the super-drive. Together they inspected the heavens and found a brilliant yellow star on their quarter. Farradyne turned the ship to face it and pushed the toggle up and down. The star reappeared without change. He kept his eye to the point-of-flight telescope and raised the toggle slowly. Sol changed color, racing toward the blue and the violet first and then turning a dull red and rising through the spectrum again until it became violet once more. It went through another spectrum change and started to increase in size.

Whatever caused this phenomeonon could not be explained by Farradyne; perhaps by no living Solan physicist until many years of research brought forth a theory.

But regardless of the theories-to-come, Sol grew in size like a toy balloon hitched to a high-pressure air line until its flare frightened the pilot. He shoved the toggle down and Sol winked back into the familiar disc of blinding sun, about the size as seen from Mars.

Farradyne oriented himself with his knowledge of common celestial navigation, consulted the spaceman's ephemeris and pointed at a large unwinking spot. "Home," he said.

Two light years an hour ... Farradyne went to the computer and made some calculations. He returned, pointed the Lancaster at Terra and flicked the toggle up and down, counting off a few seconds for drive. Sol whiffled past, changing in color as its position changed in the astrodome, and when Farradyne drove the toggle down, Terra was a distant disc in the sky above them.

Farradyne turned the outgoing gain on the intercom. "Terra dead ahead," he called to the prisoners below. "Still want to bet?"

Brenner growled. "You've got your bet. It's our lives against yours."

"Done!"
