"Then you came up after me, Tom?" said Blake, who knew the man. "You wouldn't have got much further with that team; but who sent you?"

"I don't quite know. It seems Gardner got orders from somebody that you were to be found, and he hired me and the boys. We'd trouble in getting here, but we allowed we could bring up more grub and blankets on the sled and we'd send Jake back with the team when we struck the thick bush. Then we were going to make a depot and pack along the stuff we didn't cache. But I've a letter which may tell you something."

Blake opened it and Harding noticed that his face grew intent, but he put the letter into his pocket and turned to the man.

"It's from a friend in England," he said. "You were lucky in finding me and we'll go back together in the morning."

After attending to their horses, the new arrivals joined the others at the fire and explained that at the hotelkeeper's suggestion they had meant to head for the Indian village and make inquiries on their way up at the logging camp. Though Blake talked to them, he had a preoccupied look, and Harding knew he was thinking of the letter. He had, however, no opportunity of questioning him and waited until next day, when Emile, whom they were helping, chose a shorter way across a ravine than that taken by the police and the men with the bob-sled. When they reached the bottom of the hollow, Blake told the half-breed to stop, and took his comrades aside.

"There's something I must tell you," he said. "It was Colonel Challoner who sent the boys up from the settlement with food for us and he begs me to come home at once. That's a point on which I'd like your opinion, but you shall hear what he has to say." Then, sitting down upon a log, he began to read from his letter:—

"'A man called Clarke, whom you have evidently met, lately called on me and suggested an explanation of the Indian affair. As the price of his keeping silence on the subject, he demanded that I should take a number of shares in a syndicate he is forming for the exploitation of some petroleum wells.'"

"I think it was a good offer," Harding interposed. "Clarke must have had reason for believing he was about to make a big strike; he'd have kept quiet until he was sure of the thing."

"'The fellow's story was plausible,' Blake continued reading. 'It seems possible that you have been badly wronged, and I have been troubled——' He omitted the next few lines and went on: 'As it happens, another account of the frontier action had been given me some time earlier by a lady who has been in India. It differed from Clarke's in one or two details, but agreed in exonerating you; and she also asked a price which I declined to pay. After giving the matter careful thought, I feel that these people may have hit upon the truth. It would, of course, afford me the keenest satisfaction to see you cleared, but the thing must be thoroughly sifted because——'"

Blake stopped and added quietly: "He insists upon my going home."
