"Either I knock off and eat," said Astro confidently, "or I call the foreman and you talk to Lactu."
"Feeling pretty big, aren't you?" growled the guard. "I haven't forgotten that punch in the stomach."
"Why, I hardly touched you," said Astro in mock surprise.
The guard glared at him, muttered an oath, and turned away. Astro could see that he was boiling, almost out of his mind with helpless, frustrated anger, and suddenly the young cadet realized how he would be able to move about the base freely. Grinning, he walked arrogantly in front of the guard and out of the shop into the dark Venusian night. It was very warm and many of the workers had stripped down to their trousers. He passed the open doorway of a large tool shop and glanced inside. It was empty. The men had apparently gone to eat. He suddenly stopped, turned to the guard, and growled, "If you want to settle our differences now, we can step inside."
The guard hesitated and glared at Astro. "When I settle with you, big boy, you'll know about it."
"What's the matter with right now?" asked Astro. "Yellow?" He turned and walked into the tool shop without looking back. The guard rushed after him. But the big cadet had carefully gauged the distance between them, and when he heard the rushing steps of the guard immediately behind him, he suddenly spun around, swinging a roundhouse right, catching the guard in the pit of the stomach again. The man stopped dead in his tracks. His eyes bulged and glazed, and he dropped to the floor like a stone. Astro pulled the man to the corner of the empty shop, removed the plastic helmet, and then tied and gagged him. He pulled the helmet over his own head, nearly tearing one ear off, grabbed the gun and stepped back outside. He stood in front of the door and glanced up and down the area between the buildings. Fifty feet away a group of men were working over a tube casing, but they didn't even look up.
Staying in the shadows, he walked down the lane, moving carefully. The plastic helmet would keep him from being recognized right away, but to complete his plan, he needed one of the green uniforms of the guards.
Deciding it would be too risky to walk around the base, he crouched behind a huge crate of machinery at the head of the lane. Sentries were constantly patrolling the area and he was certain that one would pass by soon. He only hoped the man would be big enough. Fifteen minutes later the cadet heard footsteps in a slow measured tread. He peered around the edge of the crate and silently breathed a thankful prayer. It was a green-clad guard, and luckily, almost as big as he was.
Crouching in the shadow of the crate, Astro tensed for the attack. It had to be quick and it had to be silent. He couldn't club the guard because of his helmet. He would have to get him around the throat to choke off any outcry.
