Astounding Stories of Super-Science, August 1930 Part 43

Once on the disc, it had swept off into s.p.a.ce at incredible speed, pausing only when some hundreds of miles above the earth and invisible from below without mechanical aid. When its vibration finally ceased that amazing city had leapt before her eyes.

Then, her own visibility restored, she had been led into the presence of that mighty little monarch, Cor, who explained that she had been seized as a hostage and would be held as an ace in the hole, pending conquest of her country. Since when she had been a prisoner aboard the disc.

Learning of Kendrick's capture, from gossip among the women, she had taken the first opportunity of coming to him, in the hope that between them they might devise some means of escape.

Indeed, that was his own fondest hope--their imperative need, if the people of America and of the earth were to be saved from this appalling menace. But what basis was there for such a fantastic hope?

Just one, that he could see.

"That thing on your wrist," he said, voicing it. "I'm surprised they let you wear one of those."

"They don't," she smiled. "I stole it!--from one of the maids in my apartment. It was the only way I could get here without being seen. I felt I must see you at once. We've got to do something, soon, or it'll be too late. I felt that, as a scientist, you might have some idea how we could get off."

"How do the people themselves get off?" he asked. "That escalator ray--do you know how they use it?"

"No, I've never been able to find out. They don't let me go near that part of the city."

Kendrick reflected a moment.

"Let's have a look at that invisibility affair," he said.

She removed it from her wrist, handed it to him. Somewhat in awe, he examined it.

The mechanism portion, which was linked in a strap of elastic metal, resembled only superficially a watch, he now saw. Rather it had the appearance of some delicate electric switch. Rectangular in shape, it was divided into two halves by a band of white crystal. In each of these halves were two little b.u.t.tons of the same material, those on one side round, on the other square.

"Which b.u.t.tons control the invisibility?" he asked.

"The square ones," she replied. "One's pushed in now, you see. If you should push the other, the first would come out--and you'd pa.s.s out of the picture, so to speak."

Kendrick was half tempted to try the thing then and there, but deferred the impulse.

"What are the round b.u.t.tons for?" he inquired instead.

Marjorie didn't know, but thought they were probably an emergency pair, in case something went wrong with the square ones. In any event, nothing happened when you pushed them.

Kendrick pushed one, just to see. It was true. Nothing happened--but he seemed to sense a faint, peculiar vibration and a wave of giddiness swept over him. On pus.h.i.+ng the other, which released the first, it stopped.

He handed the device back to Marjorie.

"There's your bracelet. Now, if I can just get one like it, I think we'll get down to earth all right."

"Oh, Mr. Kendrick!" Her eyes lit up eagerly. "Then you've thought of a way?"

"Not exactly. I think I've discovered their own way. I can't be certain, but I'm willing to gamble on it, if you are."

"Then you--you think those round b.u.t.tons are connected with the escalator rays?"

"Exactly! I think they control individual descent and ascent, just as the square ones control individual visibility and invisibility. At any rate, it's the hunch I'm going to act on right now, if you're with me."

"Oh, I'm with, you!" she breathed. "Anything, death almost, would be preferable to this."

"Then stand by, invisible. I'm going to get one of my jailors in here and relieve him of his wrist-watch."

Marjorie touched that little square b.u.t.ton on her own. She instantly became invisible.

Kendrick touched a b.u.t.ton too, a b.u.t.ton he had noticed beside the door. As he had supposed, it brought one of the Vadans.

Shutting the door quietly, he seized the fellow before he could move his hand to his wrist. Thwarted in his attempt to vanish from sight, the diminutive guard attempted an outcry. But Kendrick promptly throttled him.

Marjorie had reappeared by now and together they bound him to a chair with a gilded cord torn from the drapery.

Removing the precious mechanism from his wrist, Kendrick slipped it on his own.

"Now let's go!" he said, pressing the protruding square b.u.t.ton of the device. "We haven't a minute to--my golly, what a peculiar sensation!"

"It is rather odd, isn't it?" she laughed, pressing her own and joining him in that invisible realm.

"Feels like a combination electric ma.s.sage and cold shower! Where are you, anyway? I can't see you."

"Of course you can't!" came an unseen tinkle. "Here!"

He felt her brush him.

"Better hold hands," he suggested, then gave an invisible flush he was glad she couldn't see.

"All right. A good idea."

Her delicate hand came into his, soft, warm. Heart vibrating even faster than his body, his whole being a-quiver with a strange exaltation, Kendrick opened the door, and they left the apartment.

The next half-hour was the tensest either of then had ever experienced. Every foot of the way was fraught with peril.

Not only did they have to carefully avoid the visible swarms of little people who hurried everywhere, but had to be on their guard as well against any who might be moving about like themselves under cover of invisibility.

Nor could they use any elevator or public conveyances, but were obliged to make their way down to the concourse by heaven knew how many flights of stairs, and cross heaven knew how many teeming streets on foot, before they reached the amber court, below which the trap-door and their hope of freedom.

They got there at last, however, descended, and peered down from that yawning brink upon the desert floor--to draw back with gasps of dismay. For the area still gleamed semi-molten from the stupendous blast that had wiped out Kendrick's camp.

"W-what is it?" she gasped.

Swiftly he told her.
