"Yes," I stammered. In truth I was swept now with a shuddering revulsion for this leering cripple.

"Because," he said, "Mary Atwood loves you. When I have conquered New York with my Robots, I shall search further into Time and find an era where scientific skill will give me--shall I say, your body? That is what I mean. My soul, my ident.i.ty, in your body--there is nothing too strange about that. In some era, no doubt, it has been accomplished.

When that has been done, Mary Atwood, you will love me. You, George Rankin, can have this poor miserable body of mine, and welcome."

For all my repugnance to him, I could not miss his earnest sincerity.

There was a pathos to it, perhaps, but I was in no mood to feel that.

He seemed to read my thoughts. He added, "You think I am irrational. I am not at all. I scheme very carefully. I killed Harl for a reason you need not know. But the Princess Tina I did not kill. Not yet. Because here in New York now there is a very vital fortified place. It is operated by humans; not many; only three or four, I think. But my Robots cannot attack it successfully, and the City Council does not trust me enough to let me go there by the surface route. There is a route underground, which even I do not know; but Princess Tina knows it, and presently I will cajole her--trick her if you like--into leading me there. And, armed with the white-ray, once I get into the place--You see that I am clever, don't you?"

I could fancy that he considered he was impressing Mary with all this talk.

"Very clever," I said. "And what are you going to do with us in the meantime? Let us go with you."

"Not at all," he smiled. "You will stay here, safe with Migul. The Princess Tina and your friend Larry are much concerned over you."

Larry! It was the first I knew of Larry's whereabouts. Larry here?

Tugh saw the surprise upon my face; and Mary had clutched me with a startled exclamation.

"Yes," said Tugh. "This Larry says he is your friend; he came with Tina from 1935. I brought him with Tina from when they were marooned in 1777. I have not killed this man yet. He is harmless; and as I told you I do not want Tina suspicious of me until she has led me to the Power House.... You see, Mistress Mary, how cleverly I plan?"

What strange, childlike, naive simplicity! He added calmly, unemotionally, "I want to make you love me, Mary Atwood. Then we will be Tugh, the great man, and Mary Atwood, the beautiful woman. Perhaps we may rule this world together, some time soon."

The door slid open. Migul appeared.

"Master, the Robot leaders wish to consult with you."

"Now, Migul?"

"Master, yes."

"They are ready for the demonstration at the palace?"

"Yes, Master."

"And ready--for everything else?"

"They are ready."

"Very well, I will come. You, Migul, stay here and guard these captives. Treat them kindly so long as they are docile; but be watchful."

"I am always watchful, Master."

"It will not take long. This night which is coming should see me in control of the city."

"Time is nothing to me," said the Robot. "I will stand here until you return."

"That is right."

Without another word or look at Mary and me, Tugh swung around, gathered his cloak and went through the doorway. The door slid closed upon him. We were again alone with the mechanism, which backed into the corner and stood with long dangling arms and expressionless metal face. This inert thing of metal, we had come to regard as almost human! It stood motionless, with the chilling red gleam from its eye sockets upon us.

Mary had not once spoken since Tugh entered the room. She was huddled beside me, a strange, beautiful figure in her long white silk dress.

In the glow of light within this bare metal apartment I could see how pale and drawn was her beautiful face. But her eyes were gleaming. She drew me closer to her; whispered into my ear:

"George, I think perhaps I can control this mechanism, Migul."

"How, Mary?"

"I--well, just let me talk to him. George, we've got to get out of here and warn Larry and that Princess Tina against Tugh. And join them. It's our only chance; we've got to get out of here now!"

"But Mary--"

"Let me try. I won't startle or anger Migul. Let me."

I nodded. "But be careful."

"Yes."

She sat away from me. "Migul!" she said. "Migul, look here."

The Robot moved its huge square head and raised an arm with a vague gesture.

"What do you want?"

It advanced, and stood before us, its dangling arms clanking against its metal sides. In one of its hands the ray-cylinder was clutched, the wire from which ran loosely up the arm, over the huge shoulder and into an aperture of the chest plate where the battery was located.

"Closer, Migul."

"I am close enough."

The cylinder was pointed directly at us.

"What do you want?" the Robot repeated.

Mary smiled. "Just to talk to you," she said gently. "To tell you how foolish you are--a big strong thing like you!--to let Tugh control you."

CHAPTER XIX

_The Pit in the Dam_

Larry, with Tina and Tugh, stood in the tunnel-corridor beneath the palace listening to the commotion overhead. Then they rushed up, and found the palace in a commotion. People were hurrying through the rooms; gathering with frightened questions. There were men in short trousers buckled at the knee, silken hose and black silk jackets, edged with white; others in gaudy colors; older men in sober brown.

There were a few women. Larry noticed that most of them were beautiful.
