Astounding Stories of Super-Science, October, 1930 Part 23

Then suddenly the awful truth dawned upon d.i.c.k. The occupants of s.h.i.+ps and dirigible alike had been overcome by the deadly gas.

d.i.c.k banked, turned, leaned forward and shouted to Luke Evans, and, when the old man turned his head, indicated to him to sweep the tarmac with his ray.

The thread of black, broadening into a truncated cone, revealed nothing save the luminous outlines of the buildings. Apparently the tarmac was deserted. It was queer, too, that the silence of the night before was gone. d.i.c.k shouted again, to a.s.sure himself of what he knew already, and heard his own voice again.

Something had happened, something unexpected----or perhaps the crew of the Invisible Emperor, satisfied with the effects of the deadly gas, had not thought it necessary to go to any further trouble.

Suddenly d.i.c.k discovered that he was almost within the circle of the line of magnetic force. Hurriedly he threw over the stick and kicked rudder. It was not till he was again approaching the seash.o.r.e that it occurred to him that the force, too, was not in operation.

He opened throttle wide and shot seaward. He must ascertain what had happened, and, if not too late, give warning without delay.

Then suddenly the vicious rattle of gunfire sounded in d.i.c.k's ears, and, materializing out of the sky, came Von Kettler's face. Startled for an instant, d.i.c.k quickly realized that it was Von Kettler in his plane, with his hood thrown back.

And d.i.c.k realized that his own hood was thrown back. Two faces and nothing else, were the whole visible setting for battle.

But that look upon Von Kettler's face was even more demoniacal than before. Mad with rage at the prospective escape of his prey, and infuriated by his half-sister's appearance in the plane, Von Kettler had thrown all caution to the winds. In his insane hatred he was prepared to shoot down d.i.c.k's plane and send Fredegonde to destruction with it.

If d.i.c.k chose to replace his hood he would have the madman at his mercy. And, if he had thought about it, he would have done so, with Fredegonde sitting behind him. But the idea did not enter his mind.

Consumed with rage almost equal to Von Kettler's, he only saw there the face of one of those who had inflicted an unspeakable outrage upon the President of his country.

The memory of old Hargreaves, chained before the mock-Emperor's throne, enraged d.i.c.k more than the holocaust of lives taken by the a.s.sa.s.sins.

He shouted a wild answer to Von Kettler's challenge as his plane sped by, and banked. At that moment there came a roaring concussion that shook the plane from prop to tail.

d.i.c.k turned his head. Somehow, President Hargreaves had contrived to get the rear gun into action, and now he was staring at it as if he could not believe that he had fired it.

And that action heartened d.i.c.k wonderfully. As Von Kettler's face appeared again, he loosed his turret gun in a sweeping blast, and heard Von Kettler's gun roar futilely.

Again they crossed each other's path, and again and again, two faces, only able to gauge roughly the position of their planes. Neither man had succeeded in injuring the other.

Once old Lake turned his black ray upon Von Kettler, and for, a moment the plane stood out luminously in the blackness, but d.i.c.k leaned forward and yelled to the old man to desist.

And once d.i.c.k looked back and saw Fredegonde crouched in her c.o.c.kpit with eyes wide with terror. And yet he read in her eyes the same determination she had expressed in the laboratory. She was through with her half-brother.

All this while the wind had been increasing, making it difficult to maneuver the heavy plane; but now, of a sudden there came a dead lull, and then, with a whining sound, the wind rushed in again.

But this was a wind still more unlike any that d.i.c.k had ever known. A mighty gale that revolved circularly, but downward too, like a vortex, catching the plane and sweeping it into an ever tightening circle.

A man-made gale, upon whose wings the poison gas would spread northward again, carrying unlimited destruction with it. d.i.c.k fought in vain to free himself.

He was revolving as in a whirlpool, and it required the utmost presence of mind and watchfulness to hold the plane steady. Round and round he spun--and then, suddenly, out of the void materialized Von Kettler's face.

Von Kettler, helpless too, was spinning round upon the opposite side of the vortex. Thus each airs.h.i.+p was upon the tail of the other, and it was a matter of chance which would get the other within the ringsights of the turret gun.

Von Kettler was so near that his shouts of fury came fitfully to d.i.c.k's ears as the wind carried them. d.i.c.k, working the controls, knew that not for an instant could he direct his attention from them in order to fire his gun, and the moment Von Kettler attempted to do so, he was doomed.

Round and round, struggling, battling in vain--and once more the concussion of the rear gun shook the plane. And a shout from the President reached d.i.c.k's ears.

d.i.c.k turned his head for an instant, long enough to see Von Kettler spinning down through the vortex. And he was going down afire.

President Hargreaves, "no military man," had got him, the second time he had ever aligned a gun-barrel upon a target.

"Bravo, sir, bravo!" d.i.c.k shouted.

And desperately he flung the stick forward and nosed down.

No gale, man-made or heaven-made, could carry on its wings three-quarters of a ton of armored, turreted airs.h.i.+p. Swirling like a leaf, the plane broke through the clutch of the blast. Instantly it grew calm. Outside that vortex, hardly a breath of air was stirring.

It was as if the whole fury of the air was concentrated within that circle.

The ground came rus.h.i.+ng up. Once more d.i.c.k tried to head seaward. With flying speed lost, he was calculating the exact moment in his downward rush when he could hope to resume control. Would that moment come before he crashed?

At less than a hundred feet he partly regained control. For a moment the plane seemed to fly on an even keel. Then her nose went down as her speed slackened. And this time there was no salvation.

Working desperately to save her, d.i.c.k saw the ground loom up before him. He heard the crash as the plane broke into splintering ruin ...

he had a last vision of old Luke clutching his precious watch: then everything was dissolved in darkness....

CHAPTER XIII

_You Can't Down the Marines_

"He's pulling out of it! Keep it up, Gotch!"

d.i.c.k heard the words and opened his eyes. He stared in amazement at the faces about him. Honest American faces under tropical helmets and above a uniform that he had never expected to see again. It couldn't be real. And yet it was. One word broke from his lips:

"Marines!"

"He's got it. Don't let him slip, Gotch.", grinned one of the friendly faces, and the man named Gotch, who presumably had some qualifications for his job, continued what was meant to be a gentle ma.s.sage of the nerve centers along d.i.c.k's spine.

"I'm all right." d.i.c.k muttered, beginning to realize his surroundings. He was lying on a strip of prairie near the beach, on which the waves were breaking in low ripples about a motorboat that was drawn up.

He sat up. The world was swimming about him, but he seemed to have no broken bones. Not far away was the wrecked plane, an incongruous ma.s.s of streaks where the fabric had ripped through the gas-paint. "Where are the others?" d.i.c.k muttered.

Then he was aware of Fredegonde Valmy lying with a white face under a shrub. Her eyes were open, and turned toward him.

He heard Luke Evans's voice. The old man hobbled round from d.i.c.k's back, one arm in a bandage.

"She's hurt rather bad, Rennell, but we won't know how bad till we can get her away," he said. "You've been lying here about an hour, since we crashed. President Hargreaves made them take him to the fleet in the other motorboat to see what he could do. He's a.s.sumed command.

"You see, Rennell, that d.a.m.n gas caught the fleet and put pretty near every man out of commission for good. But these fellows wasn't going to give up. So, since all their officers were gone, they took two of the boats and their arms and equipment, and came ash.o.r.e to settle accounts. And they won't believe there's anybody on the island or any buildings. And I can't make 'em believe it. G.o.d, Rennell, those invisible devils may attack us at any moment. I don't understand what they're waiting for."

Gotch spoke: "We know you're Captain Rennell, sir. And this gentleman, we know him too, but he seems a bit queer in his head. Talking of the Invisible Emperor's headquarters on this island, a mile or so inland.
