"He's yours, Issy," he added quickly, "but you must let me care for him until—we know. Give me the chain. I won't trust him even now. He's a wolf. I've seen him take an Indian's hand off at a single snap. I've seen him tear out another dog's jugular in one leap. He's an outlaw—a bad dog—in spite of the fact that he hung to me like a hero and brought me out alive. I can't trust him. Give me the chain—"
He did not finish. With the snarl of a wild beast Kazan had leaped to his feet. His lips drew up and bared his long fangs. His spine stiffened, and with a sudden cry of warning, Thorpe dropped a hand to the revolver at his belt.
Kazan paid no attention to him. Another form had approached out of the night, and stood now in the circle of illumination made by the lanterns. It was McCready, who was to accompany Thorpe and his young wife back to the Red River camp, where Thorpe was in charge of the building of the new Trans-continental. The man was straight, powerfully built and clean shaven. His jaw was so square that it was brutal, and there was a glow in his eyes that was almost like the passion in Kazan's as he looked at Isobel.
Her red and white stocking-cap had slipped free of her head and was hanging over her shoulder. The dull blaze of the lanterns shone in the warm glow of her hair. Her cheeks were flushed, and her eyes, suddenly turned to him, were as blue as the bluest bakneesh flower and glowed like diamonds. McCready shifted his gaze, and instantly her hand fell on Kazan's head. For the first time the dog did not seem to feel her touch. He still snarled at McCready, the rumbling menace in his throat growing deeper. Thorpe's wife tugged at the chain.
"Down, Kazan—down!" she commanded.
At the sound of her voice he relaxed.
"Down!" she repeated, and her free hand fell on his head again. He slunk to her feet. But his lips were still drawn back. Thorpe was watching him. He wondered at the deadly venom that shot from the wolfish eyes, and looked at McCready. The big guide had uncoiled his long dog-whip. A strange look had come into his face. He was staring hard at Kazan. Suddenly he leaned forward, with both hands on his knees, and for a tense moment or two he seemed to forget that Isobel Thorpe's wonderful blue eyes were looking at him.
"Hoo-koosh, Pedro—charge!"
That one word—charge—was taught only to the dogs in the service of the Northwest Mounted Police. Kazan did not move. McCready straightened, and quick as a shot sent the long lash of his whip curling out into the night with a crack like a pistol report.
"Charge, Pedro—charge!"
The rumble in Kazan's throat deepened to a snarling growl, but not a muscle of his body moved. McCready turned to Thorpe.
"I could have sworn that I knew that dog," he said. "If it's Pedro, he's bad!"
Thorpe was taking the chain. Only the girl saw the look that came for an instant into McCready's face. It made her shiver. A few minutes before, when the train had first stopped at Les Pas, she had offered her hand to this man and she had seen the same thing then. But even as she shuddered she recalled the many things her husband had told her of the forest people. She had grown to love them, to admire their big rough manhood and loyal hearts, before he had brought her among them; and suddenly she smiled at McCready, struggling to overcome that thrill of fear and dislike.
"He doesn't like you," she laughed at him softly. "Won't you make friends with him?"
She drew Kazan toward him, with Thorpe holding the end of the chain. McCready came to her side as she bent over the dog. His back was to Thorpe as he hunched down. Isobel's bowed head was within a foot of his face. He could see the glow in her cheek and the pouting curve of her mouth as she quieted the low rumbling in Kazan's throat. Thorpe stood ready to pull back on the chain, but for a moment McCready was between him and his wife, and he could not see McCready's face. The man's eyes were not on Kazan. He was staring at the girl.
"You're brave," he said. "I don't dare do that. He would take off my hand!"
He took the lantern from Thorpe and led the way to a narrow snow-path branching off, from the track. Hidden back in the thick spruce was the camp that Thorpe had left a fortnight before. There were two tents there now in place of the one that he and his guide had used. A big fire was burning in front of them. Close to the fire was a long sledge, and fastened to trees just within the outer circle of firelight Kazan saw the shadowy forms and gleaming eyes of his team-mates. He stood stiff and motionless while Thorpe fastened him to a sledge. Once more he was back in his forests—and in command. His mistress was laughing and clapping her hands delightedly in the excitement of the strange and wonderful life of which she had now become a part. Thorpe had thrown back the flap of their tent, and she was entering ahead of him. She did not look back. She spoke no word to him. He whined, and turned his red eyes on McCready.
In the tent Thorpe was saying:
"I'm sorry old Jackpine wouldn't go back with us, Issy. He drove me down, but for love or money I couldn't get him to return. He's a Mission Indian, and I'd give a month's salary to have you see him handle the dogs. I'm not sure about this man McCready. He's a queer chap, the Company's agent here tells me, and knows the woods like a book. But dogs don't like a stranger. Kazan isn't going to take to him worth a cent!"
Kazan heard the girl's voice, and stood rigid and motionless listening to it. He did not hear or see McCready when he came up stealthily behind him. The man's voice came as suddenly as a shot at his heels.
"Pedro!"
In an instant Kazan cringed as if touched by a lash.
"Got you that time—didn't I, you old devil!" whispered McCready, his face strangely pale in the firelight. "Changed your name, eh? But I got you—didn't I?"
Chapter III.
McCready Pays The Debt
For a long time after he had uttered those words McCready sat in silence beside the fire. Only for a moment or two at a time did his eyes leave Kazan. After a little, when he was sure that Thorpe and Isobel had retired for the night, he went into his own tent and returned with a flask of whisky. During the next half-hour he drank frequently. Then he went over and sat on the end of the sledge, just beyond the reach of Kazan's chain.
"Got you, didn't I?" he repeated, the effect of the liquor beginning to show in the glitter of his eyes. "Wonder who changed your name, Pedro. And how the devil did he come by you? Ho, ho, if you could only talk—"
They heard Thorpe's voice inside the tent. It was followed by a low girlish peal of laughter, and McCready jerked himself erect. His face blazed suddenly red, and he rose to his feet, dropping the flask in his coat pocket. Walking around the fire, he tiptoed cautiously to the shadow of a tree close to the tent and stood there for many minutes listening. His eyes burned with a fiery madness when he returned to the sledge and Kazan. It was midnight before he went into his own tent.
In the warmth of the fire, Kazan's eyes slowly closed. He slumbered uneasily, and his brain was filled with troubled pictures. At times he was fighting, and his jaws snapped. At others he was straining at the end of his chain, with McCready or his mistress just out of reach. He felt the gentle touch of the girl's hand again and heard the wonderful sweetness of her voice as she sang to him and his master, and his body trembled and twitched with the thrills that had filled him that night. And then the picture changed. He was running at the head of a splendid team—six dogs of the Royal Northwest Mounted Police—and his master was calling him Pedro! The scene shifted. They were in camp. His master was young and smooth-faced and he helped from the sledge another man whose hands were fastened in front of him by curious black rings. Again it was later—and he was lying before a great fire. His master was sitting opposite him, with his back to a tent, and as he looked, there came out of the tent the man with the black rings—only now the rings were gone and his hands were free, and in one of them he carried a heavy club. He heard the terrible blow of the club as it
