“It was some sort of metal container, and he put the stones inside. It was something that ’ud look like part of the fittings of the foundry, and something that nobody would trouble to take away. He soldered it in, too, I gathered, so that nobody could shift it without breaking the plant. You should have heard that wicked old devil chuckle when he thought how clever he’d been!”

“I can hardly imagine that it can still be there,” said De Richleau, thoughtfully; “the place must have been ransacked a dozen times. They would not have overlooked the plant in the foundry, especially a portion which had been newly forged!”

“Old Shulimoff was an artist. I’ll bet it’s there to this day among a mass of rusty machinery. He realized they’d spot the new bit, so he had to make it all look alike. What d’you think he did?”

“Don’t know,” said Simon.

“Set fire to the house, and then legged it through the snow. That foundry can’t have been much to look at, even if there were any Reds left to look at it next day. He reckoned that he’d get back there when things were quieter, but he never did. He was lucky in falling in with a party of ‘White’ officers, and later they all got over the Persian frontier together. I’ll bet — ”

But they were never to know what Van Ryn meant to bet. The crack of a whip brought them scrambling to their feet. Twenty yards away the sleigh had leapt into motion. They had all been so interested in listening to Rex that they had forgotten to keep an eye on their prisoner. He had stealthily harnessed the horses while their backs were turned. The Duke drew his automatic and fired over Simon’s shoulder; the bullet hit an intervening tree and ricochetted with a loud whine. He ran forward, firing again and again, but the sleigh was rounding the bend of the track at full gallop on the road to Tobolsk. Rex snatched up the prisoner’s rifle, but he threw it down again in disgust. Nobody could hit a moving target through those trees.

They looked at each other in real dismay. They were now utterly helpless in the depths of the Siberian forests, an easy prey to the hunters who would soon be on their tracks. It could only be a matter of hours until they were captured, or dead of cold and exhaustion in the wastes of these eternal snows.

XIV — The Secret of the Forbidden Territory

It was Rex who broke the unhappy silence. “If we’re not the world’s prize suckers,” he declared bitterly, “I’d like to know who are!” And he began to roar with such hearty laughter that the Duke and Simon could not forbear joining in.

“This is no laughing matter.” De Richleau shook his head. “What the devil are we to do now?”
