"Yes."

He shifted himself to a more comfortable position. "They are playing for time--so that when I fail to produce the model as I agreed, then the public will realize I am not to be trusted."

"Exactly," I said.

"Well, I am playing for time, also."

He seemed so willing to discuss the thing that I grew bolder.

"What have you to gain by playing for time?" I demanded.

He stared. "You would question me, Jac Hallen? How absurd!" He looked at Elza, as though to share with her his amazement at my temerity.

Wolfgar said suddenly to Tarrano: "You will gain nothing."

Tarrano's face went impa.s.sive. I understood him better now; that cold, inscrutable look often concealed his strongest emotions. He said evenly:

"I should prefer you not to address me, Wolfgar. A traitor such as you--the sound of your voice offends me."

It struck me then as very strange--as it had for days before--that Tarrano should have failed to punish Wolfgar. I would have expected death; least of all, that Tarrano would have allowed Wolfgar to live here in the tower, in comparative ease and comfort. Tarrano's words now answered my unspoken questions. He was not looking at Wolfgar, but at Elza.

"You, Wolfgar--deserve death. You know why I cannot kill you? Why I let you stay here in the tower?" A faint, almost wistful smile parted his thin lips; he did not take his eyes from Elza.

"I am greatly handicapped, Wolfgar. The Lady Elza here would not like to have me put you to death. She would not even care to have me mistreat you. She is very tender hearted." He raised a deprecating hand. "Ah, Lady Elza, does that surprise you? You never told me I must be lenient with this traitor? Of course not."

"I----" Elza began, but he stopped her.

"You see, Lady Elza, I have already learned to obey you." He was smiling very gently. "Learned to obey even your unspoken commands."

I wondered how much of this att.i.tude might be sincere, and how much calculated trickery. Could Elza, indeed, control him?

She must have had much the same thought, for she said with a forced smile: "You give me a great deal of power. If you--wish to obey me, you'll set us free--send us all to Washington."

That amused him. "Ah, but I cannot do that."

She gained confidence. "You are willing to be very gracious in things which do not inconvenience you, Tarrano. It is not very impressive."

He looked hurt. "You misinterpret. I will do for you anything I can. But you must remember, Lady Elza, that my judgment is better than yours. I would not let you lead us into disaster. You are a gentle little woman.

Your instincts are toward humane treatment of everyone--toward mercy rather than justice. In all such things, I shall be guided by you.

Justice--tempered with mercy. A union very, very beautiful, Lady Elza ... But, you see, beyond that--you are wrong. I am a man, and in the big things I must dominate. It is I who guide, and you who follow.

You see that, don't you?"

The sincerity in his voice was unmistakable. And my heart sank as I watched Elza. Her gaze fell, and a flush mantled her cheeks. Tarrano added quietly: "We shall have no difficulty, you and I, Lady Elza. Each of us a place, and a duty. A destiny together...."

He broke off and rose quickly to his feet. "Enough. I have been weak to say so much as this."

He turned to leave us, and I became aware of a woman's figure standing in the shadows of the archway across the room. She started forward as Tarrano glanced her way. A Venus woman of the Cold Country. Yet, obviously, one of good birth and breeding. A woman of perhaps 30 years, beautiful in the Venus cast; dressed in the conventional bodice breast-plates and short skirt, with grey stockings and sandals.

Within the room, she regarded Tarrano silently. There was about her a quiet dignity; she stood with her tall, slim figure drawn to its full height. Her pure white hair was coiled upon her head, with a rich metal ornament to fasten it. And from it, a mantle of shimmering blue fabric hung down her back.

Tarrano said: "What are you doing up here? I told you to wait below."

Her face showed no emotion. But there was a glitter to her eyes, a glow in their grey depths like _alumite_ in the hydro-flame of a torch.

She said slowly: "Master, I think it would be very correct if you would let me stay here and serve the Lady Elza. I told you that before, but you would not listen."

Tarrano, with sudden decision, swung toward Elza. "This is the Elta[14]

Tara. She was concerned that I should allow you to dwell here alone with this Jac Hallen, and this traitor from Mars." His tone conveyed infinite contempt for us.

[Footnote 14: Elta--a term or t.i.tle denoting rank by birth.]

The woman said quickly: "The Lady Elza would be glad of my companionship." She shot a swift glance to Elza. What it was meant to convey, I could not have said. Perhaps Elza understood it, or thought she did. She spoke up.

"I would like to have you very much, indeed." She added to Tarrano, and there was on her face a look of feminine guile:

"You, of course, could not refuse me so small a favor? After all your protestations----"

He gestured impatiently. "Very well." And he added to Tara: "You will serve the Lady Elza as she directs."

He stalked away into the darkened pa.s.sage. In the gloom there, he stopped and again faced us; the light from a small blue tube in there illumined him dimly. He was smiling ironically.

"I shall maintain the instruments for you. The mirrors will show you Georg and Maida. They are just about arriving at the Mountain Station.

Watch them! You will see how far they progress with their wonderful speeches."

He left us. We heard his measured tread as he stalked down the tower incline. The barrage about the tower was lifted momentarily as he went out. Then it came on again, with its glow beyond our cas.e.m.e.nts, and its low electrical whine.

I was just turning back to the room when a sound behind me made me face sharply about. My heart leaped into my throat. The woman Tara had produced from about her person a weapon of some kind. She thought she was un.o.bserved, but from the angle at which I stood, I saw her. A gleaming metal object was in her hand. And then she launched it--a small flat disc of metal, thin, and with its circular edge keen as a knife-blade.

Whirling with a very soft hum hardly audible, it left her hand and floated upward across the room. Circling the cas.e.m.e.nts up near the ceiling, and then heading downward straight for Elza! And I saw, too, that the woman was guiding it by a tiny radio-control.

The thing was so unexpected that I stood gaping. But only for an instant. I saw the deadly whirling knife-disc sailing for Elza.... It would strike her ... shear her white throat....

With a shout of horror and anger, I leaped for the woman. But Wolfgar, too, had seen the disc and he went into action quicker than I. The divan was beside him. He s.n.a.t.c.hed up a pillow; flung it upward at the disc.

The soft pillow struck the disc; together, entangled, they fell harmlessly to the floor.

I was upon the woman, s.n.a.t.c.hing the handle of the control-wire from her hand, wrenching its connection loose from her robe. Under my onslaught, she fell; and I kneeled beside her, gripping her while she tore at me and screamed with hysterical, murderous frenzy.

CHAPTER XIII

_Love--and Hate_

I did not harm this Tara, though I was sorely tempted to; and after a moment we quieted her. She was crying and laughing by turns; but when we seated her on the divan she controlled herself and fell into a sullen silence. Elza, pale and frightened at her escape, faced the woman, and waved Wolfgar and me aside. Strange little Elza! Resolute, she stood there, and would brook no interference with her purpose. Wolfgar and I withdrew a pace or two and stood watching them.

Tara's breast was heaving with her pent emotion. She sat drooping on the divan, her face buried in her hands.
