"It's all quite easy," Gardiner continued. "And if it should fail there are a dozen other ways just as easy. But we won't let it fail. We mustn't let it fail, on your account."

"On my account? What more account mine than yours?"

"Well, you see, Harris, no doubt, has your letter stowed away somewhere, and it would make bad evidence for you. I don't think it mentions me at all. Besides, I know a way through a pass in these mountains, and if it doesn't turn out right—why, I'm glad I know the way. You see, I've nothing to lose, and, nobody to worry over me. But it's different with you, Hiram. You have a wife and a fine farm down in Manitoba, and it would be inconvenient for you to slip away without notice. So I say that on your account we mustn't let it fail."

"You didn't say nothin' about that before, I notice," said Riles.

"You mustn't expect me to do your private thinking as well as that of the firm," Gardiner retorted. "You had the facts—why didn't you patch them together for yourself? You're in a mess now if things don't go right. But, as I said, I'm going to stick with you and see that they do go right."

They rode along in silence in the gathering darkness. Had they been able to read each other's minds they would have been astonished at the coincidence of thought. Gardiner was planning to make away with the money when he got out of the building. Why should he divide with Riles—Riles, who would only hoard it up, and who had plenty of money already? Not at all. Riles might sue him for his share, if he wanted to—and could find him, to serve notice! On the other hand, Riles' slow wits had quickened to the point of perceiving that there lay before him a chance of making twenty thousand dollars instead of ten thousand, if he only had the nerve to strike at the strategic moment. When he got the Harrises out of the shack, by hook or crook he would leave them and follow Gardiner. He was much more than Gardiner's match in strength and he had little fear of the revolver, provided he could take his adversary unawares. If the worst came to the worst, and he could not give the Harrises the slip, he would take them with him, and they would all come upon Gardiner red-handed with the loot. Then he would explain to Harris how he had discovered Gardiner's plot and frustrated it…The idea grew upon Riles, and he rode along in a frame of mind bordering upon cheerfulness.

It was now quite dark, and the horses picked their steps carefully along the hillside trails. At last Gardiner drew up and pointed to a heavy clump of trees. A faint glimmer of light shone through it.

"That's the shack," he whispered. "They have a lantern there. We better get off the road and tether our horses in this coulee. Don't go too close; their horses may call to ours, and they will come out to meet us."

They turned down a narrow ravine with scarce room to walk single file between the branching trees. The stream was almost dry, and the horses' hoofs clanked alarmingly along the bed of the creek. They tied them where the woods closed all about them, and there seemed no chance of discovery.

"Quietly, now," said Gardiner, as they stole toward the old building. "Things seem to be working out as we planned, but we must make sure of every detail, so that we can change the attack if necessary."
