Astounding Stories, July, 1931 Part 15

"Sorry!" he said. "I see I've got to tell you something, Professor.

You think I'm merely the geologist of this expedition, but in fact I'm a secret service man from Washington, on the trail of the biggest diamond-smuggling plot in history--and here is where the trail ends!"

Professor Prescott's astonishment at these words was profound. He stood there blinking up at Stoddard, scarcely believing he had heard aright.

"You--you say you are--?"

"A detective, if you want. Anyway, if you've read the papers, you must know that for the past year or more the diamond markets of the world have been flooded with singularly perfect stones."

"Yes, I recall reading about that. They were thought to be synthetic, were they not?"

"By certain imaginative newspaper reporters, not by the experts, for under the microscope they revealed the invariable characteristics of diamonds formed by nature--the tiny flaws and imperfections no artificial means could duplicate."

"But didn't I read something, too, about some anonymous Indian rajah who was thought to be raising money by disposing of his jewels?"

"More newspaper rubbish! For one thing, British secret service men traced the rumor down and satisfied themselves there wasn't a rajah in India unloading any diamonds. For another; no rajah could possibly have the wealth involved. Why, do you know that since this plot unfolded, over five million carats' worth have made their appearance--and that means something like a billion dollars."

"Whew!" whistled the professor.

"Whew is right!" his companion agreed. "And not only have the diamond markets of the world been disorganized by this mysterious influx, but the countries involved have lost millions of dollars in revenue, due to the fact that the gems have been smuggled in without payment of duty."

"But surely, my dear fellow, you don't connect this gigantic plot with your discovery of--whatever it is you have discovered?"

"A diamond as big as a house! That's what I've discovered! And I most surely _do_ connect the plot with it. Did you ever have a hunch, Professor? Well, I had one--and it's worked out!"

"You leave me more in the dark momentarily!" declared the older man, glancing around as though to give his words a double meaning. "What was your hunch, and how did it come to lead you here?"

Whereupon Stoddard told him, swiftly, for there was no time to lose.

When first a.s.signed to the case, he said, he had been as baffled as anyone. But as he had studied the problem, one outstanding fact had given him the clue. All the gem experts agreed that the mysterious flood of smuggled stones was of Indian origin, being of the first water and of remarkable fire--in other words, of the finest transparency and brilliance.

Therefore, since they were genuine and were seemingly coming from India, Stoddard had concentrated his attention on this country, seeking their exact source. Investigation showed that there were no mines within its borders capable of producing anything like the quant.i.ty that was inundating the market.

But--and here was where the hunch came in--there was a district in the Sikkim Himalayas of Bengal whose capital was Darjeeling--Land of the Diamond Thunderbolt. Why had it been called that? Was there some legend back of it?

There was, he had learned. For though in modern times the phrase had come to apply merely to the Lama's scepter, as Professor Prescott had pointed out, originally it had carried another meaning--for legend said that once a diamond meteor had fallen on the mighty slopes of Kinchinjunga.

That had been enough for Stoddard. He had followed his hunch, had got himself attached to the American Kinchinjunga expedition--

"And that's why I'm here, and all about it," he finished. "Now, then, are you coming back with me and have a look at my Diamond Thunderbolt, or am I going back alone?"

A long moment the professor debated, before replying.

"Yes, I'll come with you," he said at length, extending his hand.

"Forgive me, Jack. I didn't know, or--"

"Forget it," said Stoddard shaking. "How the devil could you, till I told you? But just one thing. Mum's the word--right?"

"Right!"

"And one thing more. It may be--well, a one-way trip."

"Forget it."

"O. K., Professor."

With a last warm handclasp, leaving them joined in a new bond of friendship, the two men moved on over that narrow, moonlit ridge across the top of the world.

It was a desperate trail, Professor Prescott realized after scarcely a dozen steps. The ridge grew narrower, sheerer, and in places they had to straddle it, legs dangling precariously to left and right.

Admiration for his gallant companion mounted in the professor's pounding heart, as they struggled on. Only to picture anyone eager to return such a perilous way, after once getting safely back!

Other thoughts occupied his mind, too, during the next half-hour. More than once he could have sworn he saw small, ghostly figures on the ridge ahead. But he made no mention of it, for Stoddard didn't seem to see them.

Now they gained the far end of that hazardous ridge, where a sloping shelf of jagged rock offered a somewhat more secure footing. Along this they proceeded laterally for some distance.

Suddenly Stoddard paused and called out:

"Ah--there we are!" He indicated a steep pocket to the left. "Have a look down there, Professor, and tell me what you see."

Prescott lowered his eyes to the depths below, to draw back with a gasp--for what he saw was a vast phosph.o.r.escent glow, like a fallen star.

"What--what is it?" he cried, in an awed voice.

And back came the ringing reply:

"The Diamond Thunderbolt!"

"But the radiance of the thing! It couldn't reflect that much light from the moon!"

"No, and it doesn't. But there's nothing uncanny about it. Just what I expected the thing would look like at night. But come on, Professor.

You haven't seen the half of it!"

The way led down the jagged, shelving slope, now, and the descent was too precarious for further comment.

Ten minutes pa.s.sed--fifteen, possibly--when they reached a sheltered, snowless arena where t.i.tanic forces had clashed at some remote age.

Fragments of splintered rock lay strewn in wild confusion--and among them, glinting in the moonlight, were bright crystals.

Picking up one, Stoddard said laughingly:

"One of Mother Nature's trinkets worth half a million or so!"
