The cave was a quarter of the asteroid away. Rip stayed in the rear, watching for stragglers, but even Bradshaw was moving rapidly. Koa reached the cave well ahead of the rest, reached for a rack of rockets, and slapped it into the launcher.

Rip urged the men on. The Connie was squared off for another run.

They catapulted to safety as the cruiser flamed past, the exhaust splashing over the metal and sending sparks into the cave.

Rip looked out. That, if he had guessed right, was the last run. He watched the Connie's stern jet cut off, saw the nose exhaust as the cruiser decelerated to a fast stop.

"Check your weapons," he ordered.

He pulled his pistol from his knee pocket and checked it carefully. There was a clip in the magazine. Other clips were in his pocket. The clips were loaded with high velocity shells that exploded on contact. One slug could stop a Venusian krel, a mammoth beast that had been described as a cross between a sea lion and a cactus plant.

His knife was in place in the other knee pocket.

The Connie cruiser decelerated, went into reverse, and came to a full stop about a mile from the asteroid. The Planeteers saw fire in two places along the hull, marking the exhausts of two small craft.

"Snapper-boats," Koa said tonelessly. "Five men in each, if those are the regular Connie kind."

Rip made a quick decision. With only one launcher they couldn't guard the whole asteroid. "We'll stay under cover, except for Santos and Pederson. You two sneak out. Take advantage of every bit of cover you can find. I don't want you spotted. When a boat lands, report its position. The Connies operate on different communicator frequencies, so they won't overhear. We'll let them think they've burned the asteroid clean."
