He raised his head and glanced from the empty sled, empty of all but the store of dog food, to the tent, and a wild passionate light shone in his eyes. His whole expression had changed, merged into one of desperate desire. The dead man was instantly forgotten. All speculations were forgotten for the moment, absorbed in the thought of the possibility of the return of the living Tug. His busy brain was full of excitement which set his pulses hammering, and the blood rushing through his veins. But he had not stirred from his place beside the dead.
He turned his head much in the manner of a man hunted, and dreading his own shadow. His eyes peered out into the gray twilight of the forest. He was listening, too. Listening for that sound which was to tell him of the return of the owner of the camp. But no sound reached him. He saw that the dogs had crawled back to the fire, and their attitude further told him that they were still unaware of any approach.
His eyes came back to the tent and a torrent of thought poured its flood through channels which seemed bursting under the sudden pressure; and through it all passed a vague wonder as to what God or devil had inspired him to seek out the mystery of this camp.
But he sought no answer. He desired no answer. He knew that an irresistible passion was driving him, a passion he had no desire to thwart, a passion he hugged to himself and whose influence warmed him to an almost insane joy. And under its strange driving he became active. A hundred thoughts swept through his brain, each finding expression in his swiftly moving eyes.
Again he surveyed the camp. The dogs still hugged the now low-burning fire. From the fire he turned to the spot where the fuel store had evidently been kept. There was no more wood, and the axe was gone, and thus he accounted for Tug's absence. Furthermore he understood that he might return at any moment. Therefore if he were to act at all it must be at once.
He rose to his feet and moved swiftly across to the tent, and as he went the memory of all he had lost upon the trail swept over him. He told himself he had been robbed, robbed just as surely as if human hands had wrested from him the prize he had toiled so desperately to win. This came in answer to the voice of conscience; but conscience had no power against the driving force which was the whole substance of his life. Some strange fate had driven him toward an opportunity that he was not the man to miss. Charlie, that mild, harmless partner of Tug was dead; and Tug—well, Tug was probably living, but he had never been a friend of his. He had always felt subtly antagonistic toward him. What mattered if—if he robbed him? Yes, that was what he intended. He would rob him, and——
He raised the flap of the tent and passed within, letting the curtain fall behind him.
Not a sound broke the stillness outside. The dogs stirred without sound. Their ease was passing. It was almost as if they knew that the law of club and trace was soon to claim them again.
In a few moments Leo reappeared. A fresh change had come over him. His work was in full progress, and now the light in his eyes was less straining, less passionate. Now he was once more the man of purpose, keen, swift-thinking, ready. The passionate obsession that was his was once more under control, its desire having been satisfied in the acquisition of the bag of gold he now hugged in his arms. The keenest essence of his thought was at work. Possibility after possibility opened out in a series of pictures before his mind's eye, and, with swift slashes, like the progress of the surgeon's knife, his brain cut them about, extracting every detail of importance, assimilating the living, the vital points.
Though powerless to resist the temptation held out to him, he knew full well its meaning. He knew what possible consequences hovered on the horizon of his future. The morality of his act concerned him not at all, but those other considerations demanded his closest attention. All his plans must be reorganized. Now there was no need to return for laborious years on Sixty-mile Creek, and a great joy flooded his heart at the thought. He could take up his plans where they had been broken by the disaster in the storm. But there must be a difference. There must be considerable modification. He thought of Audie, and at once the necessary modifications unrolled before the keen pressure of thought he was laboring under.
