"Yes. I can follow him by his vibration-scent. I am sensitive to it, I have been with him so much. But he can never again control me!"
"When we have killed him, Migul, that will be ended forever."
"Killed him?" It seemed to frighten the Robot. "I do not know that I would dare!"
"You lead me to him," I said, "and I"ll kill him. Have no fear of that, Migul. We will work together--human friends."
"Yes. Human friends. What do you want me to do?"
Asking for orders! So nearly human, yet always something was lacking!
"Lead us to Tugh," I said promptly. "And give me that weapon."
I made a tentative reach for it, and the Robot pushed it toward me. I connected it and made sure I could fire it: its operation was obvious.
Then I stuffed the whole thing in my jacket pocket; and always afterward my hand at intervals went to that cool, sweating little cylinder. What a comfort that weapon was!
I stood up. "Shall we go now? Migul, we will have to plan what to do according to where we find Tugh. Do not go too fast; let us keep close behind you."
"Us?" The Robot was on its feet. "Do you mean this girl?"
What was this? My heart sank. I noticed, too, that Migul was planted firmly between us and the door.
"Why, of course, Migul. We can"t leave her here."
"She is not going."
"Why not?" I demanded. "Of course she"s going." I tried an experiment.
"Migul, I order you to let us out of here."
The Robot stood inert.
"Do you understand me?"
"Yes, I understand you."
"It is an order. Think about it. I control you now. Isn"t that so?"
My heart sank. Whatever the mysterious science involved in my dealing with this mechanism, I was not operating it correctly. The Robot did not move. Finally it said:
"No one--nothing--controls me. I have an independent impulse of my own. The girl must stay here until we return."
Mary gave a faint cry and sank back to the couch, a huddled white heap in her satin dress. I thought she had fainted, but she raised her face to me and tried to smile.
"But I won"t leave her, Migul."
"She must stay."
"But why? If you are human now, you must act with a reason."
"Then because, if we fail to kill Tugh, I would not have him confront me with the knowledge I have released this girl. He would derange me; end me."
"I will stay," said Mary faintly. "You go, George. But come back to me."
I bent over her; suggested, "If we locked this door so Tugh could not get in--"
Migul said, "I can do that. She will be safer here than with us. I have other reasons. She is dressed in white--a mark to betray us if we go in darkness. And she is that kind of a human you call a girl--and that style human cannot travel fast, nor fight."
It occurred to me that Mary might very well be safer here.
Again I leaned over her. "It seems horrible to leave you alone."
"I"ll stay. It may be best." Her smile was pathetically tremulous.
"Lock me in so Tugh--so nothing outside--can reach me. But, oh, George, come back quickly!"
"Yes." I bent lower, and whispered, "It"s Larry, not Tugh I really want to find--he and that Princess Tina. We"ll come back and get you, and then all of us will get away in one of the Time-cages. That"s all I want, Mary--to get us safely out of this accursed Time-world."
Migul said, "I am ready to start."
I pressed Mary"s hand. "Good-by. I will come back soon, G.o.d willing."
"Yes. G.o.d willing."
I left her sitting there and turned away. Migul slid the door open, letting in the hum and buzz of the machinery outside. But I saw that the attending Robots had all vanished. There was no mechanism of independent locomotion left.
Mary repeated, "Lock the door carefully upon me. Oh, George, come back to me!"
I essayed a smile and a nod as the door slid closed upon her.
"Is it locked, Migul?"
"Yes. Sealed."
"You are sure Tugh cannot open it? He did before."
"I have set my own lock-series. He will find it does not open."
"Show me how to open it."
The Robot indicated the combination. I verified it by trying it. I said once more, "You are sure Tugh cannot do this?"
"Yes. I am sure."
Was the Robot lying to me? Could a Robot lie? I had to chance it.
