them," Ristal told him.

I didn't like the way Ristal said that. There was a tinge of cruelty in his tone and in the sudden tightening of his lips. I hadn't ever worked with him before, or with Kresh, who was Ristal's second in command, but I didn't like the methods their manner implied. Copperd looked worried.

"I told you we were a peaceful people," I put in.

"Let me handle this," Ristal said. He pointed to a machine which stood in a corner.

"That," he explained to Copperd, "is a device which we ordinarily use in surgery and diagnosis. It has the faculty of making the nerves infinitely more sensitive to stimuli. Also to pain. Do you understand?"

"You can't use that on him!" I said. Ristal looked at me strangely.

"Of course not. But on his daughter, yes. No father likes to see his daughter suffer."

"That's out," I said flatly. "You know what our orders are."

"I know what they were. This is my own idea, Marko. Please remember that I am commander here."

I was duty bound to obey him, and I thought that I was going to obey. But as Kresh stepped toward Beth I found myself between them.

"I think that those higher up may have something to say about this," I told Ristal.

"With the information this man can give me I shall be in a position to ignore those higher up," Ristal grinned.

Kresh reached for Beth and I hit him. I knew now what Ristal had in mind. With atomic weapons he could make himself master of Venus, and of Earth. But even more important than that was the thought that he must not harm Beth.

Kresh was coming back at me. I hit him again and he went down. Then the others came piling in. There were four of them, too many for me. I fought like a madman but they overwhelmed me and held me helpless.

"Give him a shot of bental," Ristal ordered. "That ought to quiet him. Then dump him in a cabin. We'll dispose of him later."

Then Kresh was coming at me with the hypodermic needle. I felt it stab into my arm. He gave me a dose that might have killed an ordinary man.

I knew how bental worked. It was a drug that would throw me into a stupor, that would render my mind blank. Already it was taking effect. I pretended to be unconscious. Two men lifted me and carried me to a cabin, dropped me on the bunk and went out. The last thing I saw from beneath my lids was Beth being dragged toward that diabolical machine.

My senses were leaving me. I knew that I had to overcome the effects of the drug. I knew that I had to get out of that cabin. Somehow I dragged myself out of the bunk and got a porthole open. I crawled through it and dropped to the floor of the barn.

There were some loose boards and I pried them further apart and crawled out into the open. I no longer knew what I was doing; I no longer remembered Beth. I only knew that I had to run and keep on running.

My broken rib was stabbing into me like a knife. Across my chest the limb of the tree was a dead weight that crushed me. But now I knew who I was and what I was doing.

Despite the agony I managed to get my hands under the limb. I pushed up and felt it move. The pressure on my chest was gone. Inch by inch I slid out from beneath the huge branch. I staggered to my feet.

How much time had elapsed I didn't know. I was running again, but now I was running toward the dark barn. It wouldn't have taken Ristal long to get started. Maybe by now Beth was.... I shut the thought from my mind.

I was a few hundred yards away when the first scream came. Through the wind and the pelting rain it came, and it chilled me more than they had done.

My chest was aflame with every panting breath I took. But I ran as I had never run before. I had to get there before she screamed again. I had to stop them from doing this to her.

The barn door was locked. I got my fingers under the edge and ripped the wood away from the lock and went on through and into the ship.

None of them saw
