The wolf had leaped for her throat; but he fell short. She staggered from a blow, and she heard a curious sound in the region of her hip. But she didn't know that the fangs had gone home in her soft flesh. The wolf rolled on the ground; and if her pistol had possessed the shocking power of a rifle, he would have never got up again. As it was, he shrieked once, then sped off in the darkness to die. Five or six of the nearest wolves, catching the smell of his blood, bayed and sped after him. But the remainder of the great pack--fully fifteen of the gray, gaunt creatures--came stealing across the snow toward her. White fangs had gone home; and a new madness was in the air. * * * * * Straining into the silence, a perfectly straight line between Cranston's camp and Snowbird's, Dan Failing came mushing across the snow. His sense of direction had never been obliged to stand such a test as this before. Snowbird's fire was a single dot on a vast plateau; yet he had gone straight toward it. He was risking everything for the sake of speed. He gave no heed to the fallen timber that might have torn the web of his snowshoes to shreds. Because he shut out all thought of it, he had no feeling of fatigue. The fight with Cranston had been a frightful strain on muscle and nerve; but he scarcely remembered it now. His whole purpose was to return to Snowbird before the wolves lost the last of their cowardice. The jerked venison that he had munched had brought him back much of his strength. He was wholly unconscious of his heavy pack. Never did he glide so swiftly, so softly, with such unerring step; and it was nothing more or less than a perfect expression of the ironclad control that his steel nerves had over his muscles. Then, through the silence, he heard the shout of the pack as the wolf had leaped at Snowbird. He knew what it meant. The wolves were attacking then, and a great flood of black, hating bitterness poured over him at the thought he had been too late. It had all been in vain, and before the thought could fully go home, he heard the dim, far-off crack of a pistol. Was that the first of the three shots, the one she might expend on the wolves, or had the first two already been spent and was she taking the last gateway of escape? Perhaps even now Lennox was lying still on the sled, and she was standing before the ruin of her fire, praying that her soul might have wings. He shouted with all the power of his lungs across the snow.
