A hundred yards they had made, up a slight rise, when there spread before them a rutted mountain road, and on it, in full view, was a laboring Ford of ancient vintage.
Over the wheel hovered a lanky, leathery native, and beside him sat a small, plump woman who looked as though she might be his wife.
They were almost to the top of the hill when Stoddard hailed them.
"Say!" he said. "Give us a ride, will you? We"re lost."
"Keep on, Henry!" he heard the woman urge. "I don"t like the looks of "em."
Americans! Well, thought Stoddard, they were in the United States, anyway. That was something. And he didn"t exactly blame the good woman for her suspicions. They must look pretty wild, at that, with their two-day beards and tattered clothes.
"Sorry," spoke up Henry. "Missus says no. She knows best. "Sides, it ain"t fur to Martin"s Bluff. You kin make it in an hour."
"But say, wait a minute!" They were running along beside the wheezing car now. "We"ve got to get there in a hurry. We"ll pay you."
Henry p.r.i.c.ked up his ears at this, but his wife shook her head.
"Keep on!" she urged. "They may be bandits!"
Whereupon Stoddard drew his automatic, for there was no more time to argue.
"Stop!" he commanded. "You"ll take us, understand? I"ll pay you well!"
"See, I was right!" screamed the woman. "Bandits! Bandits! Oh, Henry--save me!"
Wildly she clung to him, as Stoddard mounted the running-board, but before he could make another move, Professor Prescott gasped out:
"The Cossacks! Quick!"
And jumping down, he wheeled to face the two leering Russians, not forty feet down the road. Pistols levelled, they were advancing stolidly.
Stoddard half-raised his own weapon, then turned to see if the car was within range of the return fire it would bring. It was--but not for long.
With a furious chattering of bands, as Henry gave it the gas, the decrepit vehicle gained the top of the hill and disappeared from view down the far slope, and the last thing he saw of it was a dusty plate flapping under its tail-light.
It was a Texas license!
Then, turning back, he lifted his automatic; but it was too late. The Cossacks were on them.
In answer to a guttural command, he dropped the weapon and raised his hands, as the professor had already done.
Two hours later, they were back at the rocket.
Led into the shack--which was furnished inside like an Oriental hunting-lodge--they were confronted at once by Prince Kra.s.snov.
Though his aristocratic features were immobile, it was obvious that he was in no amiable frame of mind.
"So, my friends!" he exclaimed. "I leave you in India, and meet you again in America, all within a matter of hours. It is but an example of our modern progress, is it not?"
They made no reply.
"Ha! You are not sociable, after enjoying my hospitality, my transportation? Then suppose we--as you Americans so quaintly say--call a spade a spade! I gave you your chance. You declined it.
And what is the result? My beautiful Diamond Thunderbolt, my immeasurable treasure, is buried forever."
"Through no fault of ours!" put in Stoddard.
"But buried nevertheless, and my adopted kingdom in revolt. Yet do not think I mourn too much, my friends. Though the game is what you call up, my plans shall go on. Here and elsewhere in the world, where we have sub-headquarters, are billions of dollars" worth of diamonds--supplies for years ahead. We shall not suffer. But you--Professor Prescott and Doctor Stoddard--I have a very interesting fate in store for you. How would you care to make a little scientific expedition to Mars, say?"
"Mars?" gasped the professor.
"Yes, or Venus, or even Jupiter, not to mention the moon! Or how about the sun? That would be an interesting sphere for exploration."
"We don"t know what you"re talking about," said Stoddard growing nettled. "Why mince matters? Call a spade a spade, if you"re going to!
What do you propose to do with us, now that you have us in your power?"
The prince paused, drew forth a long Russian cigarette from an exquisite platinum case.
"I propose," he smiled, when he had lit it, "to turn over my rocket to you, my fellow scientists, since I shall have no further use for it and it might be embarra.s.sing to be found with it in my possession."
And the way he proposed to turn it over to them, as they had already suspected, was to lock them in it and fire it off into s.p.a.ce.
Within the hour, the man"s diabolical plan had been put into operation.
Led to the rocket, the luckless pair were locked within a small metal room somewhere within its recesses. There sounded again the peculiar rasping that told them its doors were being sealed. And then came the roar of that mighty exhaust beating down.
There followed the lifting, rushing sensation they had experienced before, and again they were flung violently to the flooring by the force of the upward impulse.
When the pressure slacked, they staggered to their feet and groped around the dark, stuffy little room.
"Well, this is the end, I guess," sighed Professor Prescott. "I had never thought," with a grim attempt at humor, "that I would meet quite such a scientific fate as this!"
"Nor had I!" Stoddard agreed. "But I"m not quite ready to cash in my checks yet. The game isn"t over!" He was pacing around the room, knocking on the metal walls with something that gave back a strident ring. "Have you any idea what composition this stuff is?"
The professor rapped on one of the panels; felt of it.
"Aluminum, I would say."
"Nothing so lucky! If it were, I could cut it like cheese. But duralumin, probably, a very light, strong alloy; and what I have here is a hunting knife with a can-opener on one end! If I"m not mistaken, we"ll be out of this sardine box before long."
Whereupon he applied himself to the thin metal wall of their cell, working determinedly, while Professor Prescott held his cigarette lighter for a torch.
