“It’s true,” said Bob. “At least that’s what this fellow, Long Tom, declares. Long Tom—that’s his name.”

“How does he know?”

It was MacDonald who asked the question, and Bob turned to him.

“That’s what I asked him. He said Thorwaldsson had been attacked before he reached the oil country, and Thorwaldsson, Farrell and four of his men cut off from their camp. Those in the camp were killed, and Thorwaldsson’s supplies looted. He says a big band of Indians committed the outrage.”

“At whose orders?” asked Mr. Hampton.

“Merely operating on their own, says Long Tom. He was with them. They wanted the loot. What they didn’t understand, they destroyed.”

“That’s why nothing has been heard of Thorwaldsson,” said Mr. Hampton, “for his radio equipment must have been among ‘the things they didn’t understand.’ Go on, Bob.”

“Long Tom thinks Thorwaldsson spent the Winter with the Eskimos up on the rim of the Arctic Ocean.”

“Where has he been? What became of the Indians?”

“They were a hunting party, as far as I could gather, who, after chasing Thorwaldsson up to the Eskimos, left the country. But Long Tom wintered with some Eskimos near Union Straits himself, and this Spring started out. Then he fell in with Lupo, who he knew, and joined him.”
