Mrs. Carlson rose between them, tall, disheveled, dress torn open at her bosom. She seemed dazed and oblivious to what was passing, stood a moment, hands pressed to her face as one racked by an agony of pain, went to the door, and out. Carlson stood staring after her a breath, his bold chin lifted high, a look of surprise passing like a light over his eyes. "What I find will be mine," Carlson said, almost happily. "Come on--we'll fight like a couple of men!" Carlson thrust his hand into the bosom of his shirt as he spoke, and drew out a revolver with a long sweep of his mighty arm, throwing his body with the movement as if he rocked with a wild, mad joy. Mackenzie fired as Carlson lifted the weapon to throw it down for a shot. Carlson's pistol fell from his shattered hand. Swan stood a moment, that flickering light of surprise flashing in his eyes again. Then he threw back his head and shouted in the mad joy of his wild heart, his great mouth stretched wide, his great mustaches moving in his breath. Shouting still, as his Viking forebears shouted in the joy of battle, the roar of his great voice going far into the night, Swan rushed upon Mackenzie like a wounded bear. Mackenzie gave back before him, leaping aside, firing. Checked a moment, more by the flash of the discharge in his eyes than by the bullet, it seemed, Swan roared a wilder note and pressed the charge. His immense, lunging body was dim before Mackenzie through the smoke, his uninjured hand groping like a man feeling for a door in a burning house. Swan fell with the mad challenge on his tongue, and cried his defiance still as he writhed a moment on his back, turning his face to the open door and the peace of the night at last, to die. To die in greater heroism than he had lived, and to lie there in his might and wasted magnificence of body, one hand over the threshold dabbling in the dark. Mackenzie took the lantern from the corner where Reid had set it in his studious play for the advantage that did not come to his hand, and turned back to the closed door. Reid lay as he had fallen, Carlson's revolver by his side. Mackenzie stepped over him and tried the door. It was unlocked, fastened only by the iron thumb-latch. A moment Mackenzie stood, lifting the lantern to light the small room to its corners, then went in, peering and exploring into every shadow. "Great God! She wasn't here at all! And I've killed a man for that!" he said. He turned to the open door, stifled by remorse for what he had done, although he had done it in a fight that had been pushed upon him, as all his fights in the sheeplands had been pushed. He might have taken Swan at his manly offer to fight hand-to-hand to see who should open the door; or he might have allowed him to open it, and saved all violence between them.
