All this occurred during the first few hours of our imprisonment in the tower. And during the day previous, at 7 P.M. this night—70° West Meridian Time—the governments of our Earth met in Triple Conference in Great London. Three rulers pro tem—White, Yellow and Black—to replace the three who had been assassinated. The responsibility for the assassinations was placed by the Council upon Tarrano. But this—from his headquarters here in Venia—he blandly refused to accept, denying all knowledge of the murders. Venia was the principal Venus immigrant colony of Earth's Western Hemisphere. It had already been closed by our Earth Council; its inhabitants interned as possible alien enemies, pending diplomatic developments. This was the meaning of that line of official vessels lying there to the north on guard. No one could leave Venia, and for a day Venus refugees had been ordered into it from everywhere.
At 8:40 this evening came from Great London our ultimatum to Tarrano. A duplicate of it went to the Great City of Venus via the Hawaiian Station. The Earth would not recognize the Tarrano government of Venus. We would hold to our treaty of friendship with the Central State. We would remain neutral for a time. But Tarrano himself we declared an outlaw. His presence was required in Washington to stand trial for the assassinations, and the delivery in Washington of Dr. Brende's notes and model was demanded.
The ultimatum carried a day of grace; the alternate was a declaration of war by the Earth, and our immediate attack upon Venia. It was the same proposition which our War Director had previously made unofficially to Tarrano while he was there in the garden with Elza and which Tarrano so summarily had rejected.
The ultimatum came to us in the tower as we sat listening to the announcer's measured tones. Elza exclaimed:
"But why do they wait? Father's model must be here. Tarrano, the leader of all this—is here. Within the hour those vessels of war could sweep in here—capture Tarrano—recover father's model——"
Georg interrupted quietly: "No one knows if the model is here. That other car from the laboratory—we don't know where it went. The plundered laboratory has been found, of course. No station up there is near enough to have eavesdropped upon our capture, but the whole thing must have come out by now. But that aero with the model may have met an inter-planetary vessel—the model may be on the way to Venus by now."
"Georg," I exclaimed, "do you know the workings of that model? Could you build another without the notes?"
He nodded solemnly. "Yes. And they know that, in Washington. I could build another. But they know by now, that I, too, am in Tarrano's hands——"
"And he will kill you, of course, to destroy that knowledge and keep the secret for himself——" I did not say it aloud, for Elza's sake; but I thought it, and I realized that Georg was thinking it also.
Dr. Brende's secret of longevity was the crux of all this turmoil—the lever by which Tarrano was raising himself. Scores of facts amid the tumultuous news of these hours showed us that. For months, throughout Venus, Tarrano had spread the insidious propaganda that he alone had the secret of immortality—that when he was made ruler, he would use it for the benefit of his followers.
