"Good. Come on, Jane," said Strong. "This is the finish of a would-be tyrant!"

Jeff turned and dashed back into the building, while Strong and Jane climbed into the jet car and roared off toward the spaceport.

"If we only had a paralo-ray gun," muttered Roger as he and Tom sped after Vidac's powerful jet car.

"Yes," agreed Tom. "This could be a trap, but what can we do?"

Roger was silent. They had moved out of the cave as soon as Astro had been taken down the hill and they knew exactly what Vidac had in mind. But their need for information about Professor Sykes and their concern for Astro forced them to follow the powerful jet car into what they were certain was a trap.

"We'll ditch the jet car after we find out where they're going," said Tom, "and figure out something afterward."

"You think they'll go to Sykes?" asked Roger.

"It's a pretty safe bet, Roger. The professor's been well hidden, so why not hide Astro in the same place, hoping in the meantime to get us also."

"But I can't see walking into a trap, simply because we know it's there!"
