"I hadn't thought before—but it's strange," he said. "Didn't McCready say something about knowing the dog? It's possible. Perhaps he's had Kazan before and abused him in a way that the dog has not forgotten. To-morrow I'll find out. But until I know—will you promise to keep away from Kazan?"
Isobel gave the promise. When they came out from the tent Kazan lifted his great head. The stinging lash had closed one of his eyes and his mouth was dripping blood. Isobel gave a low sob, but did not go near him. Half blinded, he knew that his mistress had stopped his punishment, and he whined softly, and wagged his thick tail in the snow.
Never had he felt so miserable as through the long hard hours of the day that followed, when he broke the trail for his team-mates into the North. One of his eyes was closed and filled with stinging fire, and his body was sore from the blows of the caribou lash. But it was not physical pain that gave the sullen droop to his head and robbed his body of that keen quick alertness of the lead-dog—the commander of his mates. It was his spirit. For the first time in his life, it was broken. McCready had beaten him—long ago; his master had beaten him; and during all this day their voices were fierce and vengeful in his ears. But it was his mistress who hurt him most. She held aloof from him, always beyond they reach of his leash; and when they stopped to rest, and again in camp, she looked at him with strange and wondering eyes, and did not speak. She, too, was ready to beat him. He believed that, and so slunk away from her and crouched on his belly in the snow. With him, a broken spirit meant a broken heart, and that night he lurked in one of the deepest shadows about the camp-fire and grieved alone. None knew that it was grief—unless it was the girl. She did not move toward him. She did not speak to him. But she watched him closely—and studied him hardest when he was looking at McCready.
Later, after Thorpe and his wife had gone into their tent, it began to snow, and the effect of the snow upon McCready puzzled Kazan. The man was restless, and he drank frequently from the flask that he had used the night before. In the firelight his face grew redder and redder, and Kazan could see the strange gleam of his teeth as he gazed at the tent in which his mistress was sleeping. Again and again he went close to that tent, and listened. Twice he heard movement. The last time, it was the sound of Thorpe's deep breathing. McCready hurried back to the fire and turned his face straight up to the sky. The snow was falling so thickly that when he lowered his face he blinked and wiped his eyes. Then he went out into the gloom and bent low over the trail they had made a few hours before. It was almost obliterated by the falling snow. Another hour and there would be no trail—nothing the next day to tell whoever might pass that they had come this way. By morning it would cover everything, even the fire, if he allowed it to die down. McCready drank again, out in the darkness. Low words of an insane joy burst from his lips. His head was hot with a drunken fire. His heart beat madly, but scarcely more furiously than did Kazan's when the dog saw that McCready was returning with a club! The club he placed on end against a tree. Then he took a lantern from the sledge and lighted it. He approached Thorpe's tent-flap, the lantern in his hand.
"Ho, Thorpe—Thorpe!" he called.
There was no answer. He could hear Thorpe breathing. He drew the flap aside a little, and raised his voice.
"Thorpe!"
Still there was no movement inside, and he untied the flap strings and thrust in his lantern. The light flashed on Isobel's golden head, and McCready stared at it, his eyes burning like red coals, until he saw that Thorpe was awakening. Quickly he dropped the flap and rustled it from the outside.
"Ho, Thorpe!—Thorpe!" he called again.
This time Thorpe replied.
