The short hairs on the back of Rip's neck prickled. Far above, blackness in the shape of a spaceship blotted out stars. The Connie had arrived!

Rip ordered urgently, "Kemp! Stop cutting! The rest of you get the stuff under cover. Ram it!" He hurried to lend a hand himself, hustling crates into the cave.

Kemp had made astonishing progress. There was room for the crates, if stacked properly, and for the men, besides. Rip supervised the stacking and then the placement of the rocket launcher at the entrance.

"All hands inside the boat," he ordered. "Dowst, be ready to take off at a moment's notice. You'll have to buck this box around as never before." He explained to the pilot his plan to dodge, keeping the asteroid between the boat and the cruiser.

"We'll make it, sir," Dowst said.

"I'm not worried," Rip replied—and wished it were true. He looked up at the Connie again. It was getting larger. The cruiser was within a few miles of the asteroid.

As Rip watched, fire spurted from the cruiser, and it moved with gathering speed toward the asteroid's horizon. He watched the exhaust trail, wondering why the Connie had blasted off.

"He has something up his sleeve," Koa muttered. "Wish we knew what."

"Let's take no chances," Rip stated. "Come on."

The men were already in the boat. He and Koa joined them. They stood at a window, watching the Connie's trail.
