"Naturally," I said. It didn't matter now. It was dark enough.

"Why naturally?"

"Because," I told him, "I am a Venusian."

My tone was matter of fact. Yet they knew that I was not joking. Beth was staring at me, a growing fear and horror in her eyes. Her father seemed dazed by the revelation. I took the _del_ gun from my pocket and showed it to them.

"This is a weapon strange to you. But it is effective at this range.

Please don't make me use it."

"But what do you want?" Copperd asked.

"I want you to take a ride with me. In your car."

I let them put on their coats and then we walked out onto the porch and down the stairs. Across the street the security agent barely glanced at us. Then we got into Copperd's car, Beth and he in the front seat and I in the back. I told him in which direction to go.

At the outskirts of town we lost the car that was following us. I had planned this part of it perfectly. We pulled into a side road and turned off our lights. The agent went right past us.

"What is it you want of me?" Copperd said as we started up again.

"We want to have a long discussion with you about some matters on which you are an authority."

"And that's what this whole affair with me was for? So that you could get to my father!" Beth said accusingly. I saw her shoulders shake.

"Yes. Now turn off here."

We turned off the main road and followed a rutted trail onto an old farm.

The farmhouse was a wreck, but the barn still good. Our ship was in there.

The door opened as we walked toward the barn. Ristal's tall figure was framed in the doorway, and behind him stood Kresh, broad and ungainly.

The others crowded up behind them.

"Good work, Marko," Ristal said. We went into the ship, which filled the whole interior of the barn.

"This is Commander Ristal, of the Venusian Intelligence," I told Copperd and Beth.

"What's _your_ official t.i.tle?" Beth asked bitterly.

"I am a special agent and language expert," I told her. Then I explained why I had brought them here.

"Our civilization is in some way far in advance of yours. As you see, we have mastered interplanetary travel. But it is essentially a peaceful civilization. Our weapons, such as we have, are of limited range and power.

"When it became known that Earth was developing monstrous weapons of aggression we realized that we must be prepared for the worst. There was only one way to discover what you already had and what you were working on. Once we arrived here we found that a man named Copperd was the prime figure in his country's atomic weapons research. It became our duty to seek him out."

"I see," Copperd grunted. "And now you expect me to reveal secrets which I am bound by oath to protect with my very life?"

"You will reveal 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.
