"How about releasing the prisoners, taking over a ship, and blasting off?"

"And have the Solar Guard fleet blast us out of the skies? No, sir! Come on, we've got to get moving!"

"We could still try to release Carson and the others," said Astro stoutly.

"We can try all right, but I don't think we'll be very successful."

The two spacemen returned to the first floor of the building and headed for the rear door without so much as a look at the line of frozen guards along the wall. Once outside, they skirted the edge of the building, staying close to the hedge, and then struck out boldly across the canyon floor toward the prison building. They were surprised to see that their smashing attack had gone unnoticed, and Connel reasoned that the constant roar of activity in the canyon had covered the sounds of their raid.

"We'll have to hurry, sir," said Astro as they turned into the lane leading to the prison. "Ten minutes to twelve."

"It's no good, Astro," said Connel, suddenly pulling the cadet back and pointing to the building. "Look at all the guards—at least a dozen of them."

Astro waited a second before saying grimly, "We could try, sir."
