That Tarrano should thus defy the Earth, when by every law of rational circumstance the move seemed to spell only his own disaster, was characteristic of the man. He stood there in the instrument room at the peak of the skeleton tower in Venia and rasped out to the Earth Council his defiance. Silence followed—silence unbroken save by the hiss and click of the instruments as the message was sent.

And then Tarrano ordered thrown upon himself the lights and sending mirrors so that his own image might be available to all of the public and Earth officials who cared to look upon it. Within the circle of mirrors he stood drawn to his full height; his eyes flashing, heavy brows lowered, and a sardonic smile—almost a leer—pulling at his thin lips. The embodiment of defiance. Yet to those who knew him well—as I was beginning to know him—there was in his eyes a gleam of irony, as though even in this situation he saw humor. A game, with worlds and nations as his pawns—a game wherein, though he had apparently lost, with the confidence of his genius he knew that the hidden move he was about to make would extricate him.

"Enough," he rasped.

The mirrors went dark. He turned away; and still without appearance of haste he drew Wolfgar, Elza and me to the balcony. Together we stood gazing over the lights of the city below us.

A cloudless, starry sky. Empty of air-craft; but to the north just below the horizon, we knew that the line of war vessels was hovering. Even now, doubtless, they had their orders to descend upon us. Tarrano seemed waiting, and I suppose we stood there half an hour. Occasionally he would sight an instrument toward the north; and by the orders he gave at intervals I knew that preparations for action on his part were under way.

Half an hour. Then abruptly from below the northern horizon lights came up—spreading colored beams. The Earth war vessels! A line of them as far as we could see from left to right, mounting up into the sky as they winged their way toward us—a line spreading out in a broad arc. And then, behind us, I saw others appear. We were surrounded.

It was a magnificent, awe-inspiring sight, that vast ring of approaching colored lights. Red, green and purple—slowly moving eyes. Light-rockets sometimes mounting above them, to burst with a soundless glare of white light in the sky; and underneath, the spreading white search-beams, sweeping down to the dark forest that lay all about us.

Soon, in the white glare of the bombs, we could distinguish the actual shapes of the vessels. Still Tarrano did not move from his place by the balcony rail. He stood there, with a hand contemplatively under his chin, as though absorbed by an interest in the scene purely impersonal. Was he going to give himself up? Stand there inactive while these armed forces of the most powerful world in the Solar System swept down upon him?

Abruptly he snapped his instrument back to his belt. He had not used it since the hostile lights had appeared. Previously, I knew, he had been watching those lights, with the curved ray of the instrument when the lights themselves had been below the horizon.

He turned now to me. "They are here, Jac Hallen. Almost here. And I am at their mercy." His tone was ironic; then it hardened into grimness. He was addressing me, but I knew it was for Elza's benefit he spoke.

"I came here to Earth, Jac Hallen, for certain things. I find them now accomplished. I belong here no longer." He laughed. "I would not force myself into a war prematurely. That would be very unwise. I think—we shall have to avoid this—engagement. I am—slightly outnumbered."

He called an order, quite calmly over his shoulder. I suppose, at that moment, the Earth war vessels were no more than five miles away. The whole sky was a kaleidoscope of darting lights. In answer to his order, from the peak of our tower a light bomb mounted—a vertical ray of green light. The bomb of surrender!

Tarrano chuckled. "That should halt them. Come! We must start."

He held a brief colloquy with a Venus man who appeared beside him. The man nodded and hastened back into the instrument room. The green light of our bomb had died away. The lights in the sky began fading—the whole sky fading, turning to blackness! I became aware that Tarrano had thrown around our tower a temporary isolation barrage. For a few moments—while the current he had at his command could hold it—we could not be seen on the image finders of the advancing vessels.

Tarrano repeated: "That should hold them—I have surrendered! They should be triumphant. And outside our barrage, our men will bargain with them. Ten minutes! We should be able to hold them off that long at least. Come, Lady Elza. We must start now."

With a scant ceremony in sharp contrast to his courteous words to Elza, he hurried us off. Three of us—Elza, Wolfgar and myself, with one attendant who still carried Elza's personal belongings. Hurried us into the vertical car which had brought us up into the tower. It descended now, down the iron skeleton shaft. Outside the girders I could see only the blackness of the barrage, with faint snapping sparks.

Silently we descended. It seemed very far down. And suddenly I realized that we were going lower than the ground level. The barrage sparks had vanished. The blackness now was a normal darkness; and in it I could see slipping upward the smooth black sides of the vertical shaft into which we were dropping. And the sulphuric smell of the barrage was gone. The air now smelt of earth—the heavy, close air of underground.

I do not know how far down we went. A thousand feet perhaps. The thing surprised me. Yet in those moments my mind encompassed it; and many of Tarrano's motives which I had not reasoned out before now seemed plain. He had come from Venus to the Earth, possibly several months ago. Had come directly here to Venia and set up his headquarters. His purpose on Earth—as he had just told me—did not lie with warfare. While he was here his forces had conquered the Great City of Venus, and just now, the Hill City of Mars. He controlled Venus and Mars—but he was still far from ready to attack the Earth.

He had come to the Earth in person for several important purposes. For one—he desired the Brende model and Dr. Brende's notes. He had them now; they were, in reality, at this present moment in the Great City of Venus. Also, with the Brende secret—to control it absolutely—he had to have Georg Brende. Well, as I was soon to realize, Georg was now his captive. And the Princess Maida? His purpose in holding her was two-fold. She had, now as always in the Venus Central State, a tremendous sentimental sway upon her people. Tarrano had abducted her, forcibly to remove her from the scene of action, so that during her unexplained absence his propaganda would have more influence. He had brought her here to Earth; and now his plan was to have Georg Brende and her fall in love with each other. He still hoped to win Georg to his cause, by giving him the Princess Maida, if for no other reason. And with Maida married to Georg—and Georg in Tarrano's service—Maida herself would turn her influence in Venus to consolidate her people to Tarrano.

These, in part, were Tarrano's present plans and motives. They were working out well. And—as he had said—the Earth did not concern him now as a battle-ground. Later ... But even with this sudden insight which seemed to come to me, I was inadequate to grasp what later he was to attempt.

While thus occupied with my thoughts, we were steadily descending into the ground under Venia—dropping out of sight while above us, perhaps by now, the eager warcraft of Earth were overwhelming the city. Tarrano had not spoken; but when at last our little car bumped gently at the bottom, he said smilingly: "We are here, Lady Elza."

We left the car, and passed into a dim-lighted cavern. I saw a lateral black tunnel-mouth yawning nearby, with a shining rail at its top and bottom, one above the other. And between the rails was a metal vehicle. A long, narrow car; yet with its turtle-back and its propelling gas-tube at the rear, with a rudder on each side of the tube, I realized that it was designed also for sub-sea travel. A small affair. Ten feet at its greatest width, and fifty or sixty feet long.

There was nothing startling in this evidence of underground and sub-sea transportation. But that it should be here in primitive Venia surprised me. Then I realized that Tarrano had been here perhaps many months. Quietly, secretly he had constructed this underground road. For his escape, I could not doubt it. Indeed, I did not doubt but that the man had anticipated practically every event which had occurred.

We found in the car, or boat if you will, a variety of attendants and personal belongings. Tara was there; I saw her sitting alone on one of the distant rings of seats. And Argo was among us—and others whom I had learned to know by sight and name. It was the party and equipment which Tarrano had probably originally brought with him from Venus. We, the last arrivals in the car, took our places. The doors slid closed. The car vibrated slightly; purred with its forward motors. We were started.

It was not a long trip. How far we went I have no means of knowing. But after a time, by the changed motion and sounds, I realized that we were traversing water. Then above us after another interval, they opened a hatchway. The pure fresh air of night streamed in upon us. Every light in the boat had been extinguished. At Tarrano's command I followed him up the small spider incline and through the hatchway. We stood on a little circular space of the turtle-deck, well aft—an observation space enclosed by a low metal rail. A few feet below us dark glossy water was slipping past.

At a lazy hasteless pace, we were passing along what I saw to be a broad river. The Riola Amazonia[16] I afterward learned it to be. Heavy banks of luxurious foliage, dark and silent. Inundated in places. And after a few moments we slackened, turned sharply into one of the inundated coves and nosed slowly amid a tangle of the jungle bank.

And then I saw, hidden here in the recesses of this pathless forest, a small inter-planetary flyer, painted a hazy grey-blue. Around and over it the vegetation had been carefully, cunningly trained. A few cautious lights illumined it now; but without them, and even in daylight, I knew that from above it could never be seen.

Our party entered it—a small but surprisingly luxurious vessel. The foliage from above it was cut away by ready workmen; and in half an hour more we were rising from the forest. Straight up, into that cloudless sky. The land dropped away beneath us; visually concave at first as the circular horizon seemed to rise with us. The sky overhead fortunately was empty—nothing in sight to bar our outward flight. And we carried no lights.

In a moment or two, so swiftly did we gather velocity, the lights of Venia—a distant patch of them—were visible. Then, further away, I presently saw the grey expanse of open sea. And as we mounted, the simulated concavity of the Earth turned convex. I had never seen it thus—had never been so far above its surface before. A huge grey ball down there which was our Earth. Outlines of sea and land. Then continents and oceans, enveloped by patches of cloud area. A grey ball, changing to a glowing, vaguely dull red; then silver. Dwindling—gleaming brighter silver on one side where the sunlight struck it.

We were in the realms of outer, inter-planetary space!
