Neilson was just finishing hacking at his hair with the short-bladed safety razor. He scowled at Treb, his eyes on the carbine that the man from Baryt yet carried. "Not taking any chances, eh, Treb?" "Just in case you change your mind, Harl." "My friend--my very dear friend--Gram Treb!" Neilson laughed. "What trust--what a faith in human nature!" "Yes, Harl. Your friend." They left the lake behind, Neilson in advance. Directly ahead, beyond the outer ring of trees, the locks to the upper levels waited. They had less than a third of a mile to traverse. The rusting shattered debris of a machine gun, with a spilled clutter of empty shell cases, lay just off the trail. "Harok Dann died here," said Treb. Neilson did not turn. "The big man, Manross, was killed by Dann's fire even as he threw the grenade," he added. Treb was watching the broad-shouldered figure ahead. "Shut it off, Treb, will you?" Neilson shouted, turning. "Isn't it tough enough without you yap-yapping all the way?" Treb's lips thinned. The knife chafed his leg. Already he was limping slightly. But they had covered more than half the distance. Once they contacted the UN guards and were through the locks he could relax.... * * * * * The circular outer face of the lock was before them. And the button that summoned the guards jutted redly from a shoulder-high recess. Neilson leaned against the lock, his narrowed eyes on Treb as he reached for the button. Treb jabbed. And he relaxed inwardly. Too late now for Neilson to attempt overpowering him and claiming the victory. He had feared such an attempt--with the lust for the woman, Jane Vanne, driving him, Neilson might have gone back on his word. It was tough going for the kid. But he wasn't losing anything worth keeping. And hundreds of fine young lads like him might be spared going through this ordeal in space. They'd.... Neilson's fist caught him behind the ear. That split-second of inattention was proving costly. Neilson clamped the carbine barrel, wrested it away from Treb. He raised it. Treb lifted his hands. "So now it's me at the controls," Neilson said, grinning. "Any reason why I should go through with your Hubble Award idea?" "The guards will be here in no more than a minute, Harl. Throw the gun away and we'll go through together." Neilson's eyes were shining. He was seeing the crowds waving crazy welcome as his space ship grounded. He was seeing the adulation of the boys, and the adoring glance of the dark-eyed girl named Jane. He was seeing the medals and the banquets and the bundles of money. "You were crazy, Treb," he said, "to ever trust me. In war promises mean nothing. Study your history." Treb squared his shoulders, his hands came down. "If that's the way it is," he said, and then, "coming at you, Neilson."
