"What?"

"Larkwell's an enemy agent...." He hesitated.

"And...?"

"Why didn't he attempt to solicit your aid?" Crag finished bluntly.

"You're a spaceman, Commander, not an intelligence agent."

"I don't get the connection."

"An agent trusts no one. And a saboteur is the lone wolf of the agents. Trust me? Ha! He'd just as soon trust your good Colonel Gotch. No, Larkwell wouldn't have trusted me. Never."

Crag was silent. An agent who couldn't trust a soldier of his own country, even when the chips were down? It was a philosophy he couldn't understand. As for Larkwell! He vowed he'd live long enough to see him dead. More, he'd kill him himself. He was planning how he'd accomplish it when they reached the rill where Red Dog was buried. He switched his torch on and ran it along the edge of the chasm until he located the rope ladder leading down to the airlock.

"You lower 'em and I'll pack 'em." Crag ordered. He descended into the rill and began moving the cylinders Richter lowered to him. Finished, he examined the cylinders they had brought earlier. Empty! His lips set in a thin line as he examined the cylinders which the rocket had brought from earth. Empty ... all empty. Larkwell had done a thorough job.

He gritted his teeth. Before he was through he'd ram the empty cylinders down Larkwell's throat. Yeah, and that wasn't all. He contemplated the step-by-step procedure. Larkwell would die. Die horribly. He looked toward the hatch wondering what was detaining Richter. He waited a moment, then climbed back to the plain. The German was nowhere in sight.
