The black uniform was dirty and greasy which surprised Comstock. He'd never before seen an R.A. who was not spotless. However, when he saw what the man had been working on he was no longer surprised. The man waved a filthy hand at an object on four wheels and said, "Try this one. I'm having a lot of trouble with these blasted things." He shook his head. "If we only had some new parts. I don't know how much longer I can keep stealing parts from one car and putting them in another." Comstock had to make a decision. His hand still on his stun-gun, he said to Grundy, "Get behind that wheel, and let's get started." Slightly taken aback, Grundy gulped and then said, "Yes sir. Right away, sir." There was no other way that Comstock could see that it could be done. An R.A. would not have driven the car and allowed the two prisoners to sit idly in the back of the conveyance. The dirty uniformed man, mumbling under his breath, got down on all fours and began to tinker with the underneath part of the "car" he had been working on when they entered the "garage". That was a bit of luck for it allowed Grundy to enter the "car," get behind the wheel and examine the various controls. Comstock and Helen sat grandly in the back seat and waited. Finally, after a long wait, Comstock leaned forward and whispered to Grundy, "Better get started before he gets suspicious." He was a little shocked at the curses that Grundy directed at him. They ended by the man saying, "All right, genius, you tell me what to do!" The dirty man's legs were all that showed from the place where he was working. Comstock leaned over Grundy's shoulders and said, "What about that key? It seems to be part of the works." Shrugging, Grundy turned the key. There were a lot of things sticking up out of the floor and Comstock said, "They look like feet would fit on them, don't they?" Sticking out one foot experimentally, Grundy said, "Hmmm ... yes, they do." Then there was a series of explosions, and a sudden jolting start that threw Comstock into Helen's lap. * * * * * Later, when they had learned a bit about driving, they were all very grateful that the "car" had been pointed at the opening in the door when it started, for they knew that they would never have been able to figure out how to reverse it. Their vehicle bucked and bounced as it roared out through the doorway. It was only after the first thirty seconds of movement that Grundy remembered that the other driver had held his hands on the wheel. Trying this, he found that the car responded to his touch. Rather delighted, he turned the wheel sharply. Instantly Comstock was thrown off Helen's lap onto the floor of the "car". She landed on top of him driving the breath out of his lungs in a gasp that he momentarily feared was so noisy that The Grandfather, perched high in his tower, would hear. But the sound of the explosions in the front of the car drowned out all other noises.
