Astounding Stories of Super-Science, October, 1930

I came from my reverie to find De Boer before me. He was standing with legs planted wide, arms folded across his deep chest, and on his face an ironic smile.

Dick 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 expec...

"I've been at work all the time," said the old man, "not far from here. I knew the day would come when you'd need me. I put my pride aside for the sake of my country."

He barked a command, and instantly Dick was seized by two of the guards, one of whom--the one Dick had knocked down--took the occasion to administer a buffeting in the process o...

Fredegonde Valmy implicated in the conspiracy! That was the first thought that flashed into Dick's mind as he recovered consciousness. He might have suspected it! But the idea t...

Save for the workman, he was alone in a rotunda, open to the sky, and, as he had supposed, the whole upper portion of the dome had been flung back, leaving an immense aperture i...

Captain Richard Rennell, of the U. S. Air Service, but temporarily detached to Intelligence, thought that Fredegonde Valmy had never looked so lovely as when he helped her out o...

It was the sound of his name, spoken repeatedly, that brought Dick back to consciousness. He opened his eyes, blinking in broad daylight. He stared about him, and the first thin...

As Dick's airship veered and side-slipped, he kicked hard on the left rudder and brought the nose around. Furiously he sprayed the air with a leaden hail from his quick-firer. H...

Upon those squares and oblongs of bare earth, incredible as it seemed, rose the structures of the Invisible Empire, themselves both invisible and transparent, so that one looked...

Colonel Stopford's car had been parked around the corner of the building, and within a minute the four men were inside it, Stopford at the wheel, and racing in the direction of...

I must go back now to picture what befell Jetta that afternoon while I was at Spawn's mine. It is not my purpose to becloud this narrative with mystery. There was very little my...

There was an instant when it seemed that Spawn would strike the girl. The blood drained from his face, leaving his dark eyes blazing like torches. His hamlike fist went back, bu...

There was a moment when I had an opportunity to speak with Jetta. Gutierrez sat watchfully by the archway corridor entrance with a needle projector across his knees. The fellow...

The Superintendent of the penitentiary frowned, yet there was something of perplexity in the look he gave the prisoner. "Von Kettler, I think it is time that you dropped this ab...

Fredegonde took command, repressing her agitation with a visible effort. "They cannot break down that door," she said, "and they dare not ask for another key. It will take them...

Three hours later, about the time when the war council rose after completing its plans, a sudden shift of the wind blew the poison gas out to sea, just when it appeared certain...

During this flight of some six hours--north, and then, I think, northeast--to the remote Lowland fastness where De Boer's base was located, I had no opportunity to learn much of...

My blade was in my hand. If he showed himself I could slash his throat, doubtless. But what about Jetta? My thoughts flashed upon the heels of my defiant invitation. Suppose, as...

I was dimly conscious of being inside the cubby of the car, with bandits sitting over me. The car was rolling through the village streets. Ascending. We must be heading for Spaw...

In the year 2020 the oceans have long since drained from the surface of the earth, leaving bared to sun and wind the one-time sea floor. Much of it is flat, caked ooze, cracked...
