"If you're alive," Bob snarled wrathfully. "And you won't be unless you release the asteroid."

"I'll see you in Hades first!"

"Hades," remarked Bob coldly, "here you come!"

He snapped the hauler into its mile-a-second speed again, stopped it at zero. And the "yo-yo" went on its lone, destructive sortie.

For a fraction of a second Wally Saylor exhibited the countenance of a doomed man. In the telaudio plate, he whirled, and diminished in size with a strangled yell.

The "yo-yo" struck again, but Bob Parker maneuvered its speed in such a manner that it struck in the same place as before, but not as heavily, then rebounded and came spinning back with perfect, sparkling precision. And even before it snugged itself into its berth, it was apparent that the Saylor brothers had given up. Like a wounded terrier, their ship shook itself free of the asteroid, hung in black space for a second, then vanished with a flaming puff of released gravitons from its still-intact jets.

The battle was won!


As soon as the hauler had grappled itself onto the prized asteroid, Bob Parker jumped to his feet with a grin on his face as wide as the void. Queazy grabbed his arm and pounded his shoulder. Bob shook him off, losing his elation.

"Cut it," he snapped. "It's too early for the glad-hand business. We've solved one problem, but we've run into another, as we knew we would."
