But Trent was no longer aware of the soldier. And he saw that Mathieson was no longer looking at the guard. For a brief instant their eyes met, and Trent saw a stunned look in the scientist's, then Fred's gaze swept up into the night. Up into the darkened sky where, miles above them, the hurtling rocket was even now reaching the apex of its flight.

Up where a man rode on a perilous trip into the unknown.


Gaddon hunched in the darkness of the rocket, waiting. He had counted the remaining minutes off, one by one. And he knew that finally the moment was at hand.

It would be too late now to stop him. They had not noticed his absence, and if they had, they would not delay the launching for him. He had taken that fact into consideration.

And now that the moment was close to completion, he felt a glowing sense of triumph within him. He would now show those fools, and especially Mathieson. He would prove conclusively that cosmic rays were what he had said they were—a source of the energy of life, a fountain from which youth and vitality would pour, making his body immortal. He would go down in history as one of the greats of science. A man who had risked his life to prove his theory. A man who would be the first to achieve the goal of the ages, the dream of the philosophers, eternal life.

The triumph would be his. All his!

And the rocket tubes exploded into sound.

Gaddon tensed in the darkness, gripping the safety straps he had attached to himself. Beside him he felt the cat let out a frightened mewing sound as the roar of the exploding rocket power grew. He felt the furry body rubbing against his side, seeking sanctuary against this dread sound.

And then the rocket trembled with sudden movement.
