The Ethical Engineer(37)

They slipped the chain and laid it silently on the ground, then drifted noiselessly to the door.

"Is there a guard outside?" Jason asked.

"Not that I know. I don't think they have enough men here to guard all the slaves."

The door would not budge when they pushed against it, and there was just light enough to make out the large keyhole of a massive inset lock. Jason probed lightly with the pick and curled his lip in contempt.

"These idiots have left the key in the lock." He pulled off the stiffest of his leather wrappings and after flattening it out pushed it under the badly fitting bottom edge of the door, leaving just a bit to hold onto. Then he poked lightly at the key through the keyhole and heard it thud to the ground outside. When he pulled the leather back in the key was lying in the center of it. The door unlocked silently and a moment later they were outside, staring tensely into the darkness.

"Let's go! Run, get away from here," Snarbi said and Jason grabbed him by the throat and pulled him back.

"Isn't there one drop of constructive intelligence on this planet? How are you going to get to Appsala without food or water, and if you find some—how can you carry enough? You want to stay alive follow my instructions. I'm going to lock this door first so that no one stumbles onto our escape by accident. Then we are going to get some transport and leave here in style. Agreed?"

The answer was only a choked rattle until Jason opened his fingers a bit and let some air into the man's lungs. A labored groan must have meant assent because Snarbi tottered after him when he made his way through the dark alleys between the buildings.

Getting clear of the walled refinery town presented no problem since the few sentries were only looking for trouble from the outside. It was equally easy to approach Jason's leather-walled worksite from the rear and slip through it at the spot where Jason had cut the leather and sewn up the opening with thin twine.

"Sit here and touch nothing or you will be cursed for life," he commanded the shivering Snarbi, then slipped towards the front entrance with a small sledge hammer clutched in his fist. He was pleased to see one of Edipon's other sons on guard duty, leaning against a pole and dozing. Jason gently lifted his leather helm with his free hand and tapped once with the hammer: the guard slept even more soundly.

"Now we can get to work," Jason said when he had returned inside, and clicked a firelighter to the wick of a lantern.

"What are you doing? They'll see us, kill us—escaped slaves."

"Stick with me Snarbi and you'll be wearing shoes. Lights here can't be seen by the sentries, I made sure of that when I sited the place. And we have a piece of work to do before we leave—we have to build a caroj."

They did not have to build it from scratch, but there was enough truth in the statement to justify it. His most recently rebuilt and most powerful engine was still bolted to the test stand, a fact that justified all the night's risks. Three caroj wheels lay among the other debris of the camp and two of them were to be bolted to the engine while it was still on the stand. The ends of the driving axle cleared the edges of the stand, Jason threaded the securing wheel bolts into place and utilized Snarbi to tighten them.

At the other end of the stand was a strong, swiveling post that had been a support for his test instruments, and seemed strangely large for this small task. It was. When the instruments were stripped away a single bar remained projecting backwards like a tiller handle. When a third wheel was fitted with a stub axle and slid into place in the forked lower end of the post the test stand looked remarkably like a three-wheeled, steerable, steam engine powered platform that was mounted on legs. This is exactly what it was, what Jason had designed it to be from the first, and the supporting legs came away with the same ease that the other parts had been attached. Escape had always taken first priority in his plans.

Snarbi dragged over the crockery jars of oil, water and fuel while Jason filled the tanks. He started the fire under the boiler and loaded aboard tools and the small supply of krenoj he had managed to set aside from their rations. All of this took time, but not time enough. It would soon be dawn and they would have to leave before then, and he could no longer avoid making up his mind. He could not leave Ijale here, and if he went to get her he could not refuse to take Mikah as well. The man had saved his life, no matter what murderous idiocies he had managed to pull since that time. Jason believed that you owed something to a man who prolonged your existence, but he also wondered just how much he still owed. In Mikah's case he felt the balance of the debt to be mighty small, if not overdrawn. Perhaps this one last time.
