I had been on my bunk. I sank back at the gesture of his huge hairy arm.

His forearm was bare now; the sear of a burn on it was plain to be seen.

He remarked my gaze.

"True. You did that, Haljan, in Great-New York. But I bear you no malice. I want to talk to you now."

He cast about for a seat, and took the little stool which stood by my desk. His hand held a small cylinder of the Martian paralyzing ray; he rested it beside him on the desk.

"Now we can talk."

I remained silent. Alert. Yet my thoughts were whirling. Anita was alive. Masquerading now as her brother. And, with the joy of it, came a shudder. Above everything, Miko must not know.

"A great adventure we are upon, Haljan."

My thoughts came back. Miko was talking with an a.s.sumption of friendly comradeship. "All is well--and we need you, as I have said before. I am no fool. I have been aware of everything that went on aboard this ship.

You, of all the officers, are most clever at the routine mathematics. Is that so?"

"Perhaps," I said.

"You are modest." He fumbled at a pocket of his jacket, produced a scroll-sheaf. I recognized it: Blackstone's figures; the calculation Blackstone roughly made of the elements of the asteroid we had pa.s.sed.

"I am interested in these," Miko went on. "I want you to verify them.

And this." He held up another scroll. "This is the calculation of our present position. And our course. Hahn claims he is a navigator. We have set the ship's gravity plates--see, like this--"

He handed me the scrolls; he watched me keenly as I glanced over them.

"Well?" I said.

"You are sparing of words, Haljan. By the devils of the airways, I could make you talk! But I want to be friendly."

I handed him back the scrolls. I stood up; I was almost within reach of his weapon, but with a sweep of his great arm he abruptly knocked me back to my bunk.

"You dare?" Then he smiled. "Let us not come to blows!"

"No," I said. I returned his smile. In truth, physical violence could get me nothing in dealing with this fellow. I would have to try guile.

And I saw now that his face was flushed and his eyes unnaturally bright.

He had been drinking alcolite; not enough to befuddle him--but enough to make him triumphantly talkative.

"Hahn may not be much of a mathematician," I suggested. "But there is your Sir Arthur Coniston." I managed a sarcastic grin. "Is that his name?"

"Almost. Haljan, will you verify these figures?"

"Yes. But why? Where are we going?"

He laughed. "You are afraid I will not tell you! Why should I not? This great adventure of mine is progressing perfectly. A tremendous stake, Haljan. A hundred millions of dollars in gold-leaf; there will be fabulous riches for us all, when that radium ore is sold for a hundred million in gold-leaf."

"But where are we going?"

"To that asteroid," he said abruptly. "I must get rid of these pa.s.sengers. I am no murderer."

With half a dozen killings in the recent fight this was hardly convincing. But he was obviously wholly serious. He seemed to read my thoughts.

"I kill only when necessary. We will land upon the asteroid. A perfect place to maroon the pa.s.sengers. Is it not so? I will give them the necessities of life. They will be able to signal. And in a month or so, when we are safely finished with our adventure, a police ship no doubt will rescue them."

"And then, from the asteroid," I suggested, "we are going--"

"To the Moon, Haljan. What a clever guesser you are! Coniston and Hahn are calculating our course. But I have no great confidence in them. And so I want you."

"You have me."

"Yes. I have you. I would have killed you long ago--I am an impulsive fellow--but my sister restrained me."

He gazed at me slyly. "Moa seems strangely to like you, Haljan."

"Thanks," I said. "I'm flattered."

"She still hopes I may really win you to join us," he went on.

"Gold-leaf is a wonderful thing; there would be plenty for you in this affair. And to be rich, and have the love of a woman like Moa...."

He paused. I was trying cautiously to gauge him, to get from him all the information I could. I said, with another smile, "That is premature, to talk of Moa. I will help you chart your course. But this venture, as you call it, is dangerous. A police-ship--"

"There are not many," he declared. "The chances of us encountering one is very slim." He grinned at me. "You know that as well as I do. And we now have those code pa.s.s-words--I forced Dean to tell me where he had hidden them. If we should be challenged, our pa.s.s-word answer will relieve suspicion."

"The _Planetara_," I objected, "being overdue at Ferrok-Shahn, will cause alarm. You'll have a covey of patrol-ships after you."

"That will be two weeks from now," he smiled. "I have a ship of my own in Ferrok-Shahn. It lies there waiting now, manned and armed. I am hoping that, with Dean's help, we may be able to flash it a signal. It will join us on the Moon. Fear not for the danger, Haljan. I have great interests allied with me in this thing. Plenty of money. We have planned carefully."

He was idly fingering his cylinder; his gaze roved me as I sat docile on my bunk. "Did you think George Prince was a leader of this? A mere boy.

I engaged him a year ago--his knowledge of ores is valuable."

My heart was pounding, but I strove not to show it. He went on calmly.

"I told you I am impulsive. Half a dozen times I have nearly killed George Prince, and he knows it." He frowned. "I wish I had killed him, instead of his sister. That was an error."

There was a note of real concern in his voice. Did he love Anita Prince?

It seemed so.

He added, "That is done--nothing can change it. George Prince is helpful to me. Your friend Dean is another. I had trouble with him, but he is docile now."

I said abruptly, "I don't know whether your promise means anything or not, Miko. But George Prince said you would use no more torture."

"I won't. Not if you and Dean obey me."
