Such villainy set heart and brain on fire with rage and indignation: such villainy in his own brother, till lately love-worthy, praiseworthy, though a fool for meekness. He would kill Christian; had he lives many as the footprints he had trodden, vengeance should demand them all. In a tempest of murderous hate he followed on in haste, for the track was plain enough, starting with such a burst of speed as could not be maintained, but brought him back soon to a plod for the spent, sobbing breath to be regulated. He cursed Christian aloud and called White Fell's name on high in a frenzied expense of passion. His grief itself was a rage, being such an intolerable anguish of pity and shame at the thought of his love, White Fell, who had parted from his kiss free and radiant, to be hounded straightway by his brother mad with jealousy, fleeing for more than life while her lover was housed at his ease. If he had but known, he raved, in impotent rebellion at the cruelty of events, if he had but known that his strength and love might have availed in her defence; now the only service to her that he could render was to kill Christian. As a woman he knew she was matchless in speed, matchless in strength; but Christian was matchless in speed among men, nor easily to be matched in strength. Brave and swift and strong though she were, what chance had she against a man of his strength and inches, frantic, too, and intent on horrid revenge against his brother, his successful rival? Mile after mile he followed with a bursting heart; more piteous, more tragic, seemed the case at this evidence of White Fell's splendid supremacy, holding her own so long against Christian's famous speed. So long, so long that his love and admiration grew more and more boundless, and his grief and indignation therewith also. Whenever the track lay clear he ran, with such reckless prodigality of strength, that it soon was spent, and he dragged on heavily, till, sometimes on the ice of a mere, sometimes on a wind-swept place, all signs were lost; but, so undeviating had been their line that a course straight on, and then short questing to either hand, recovered them again. Hour after hour had gone by through more than half that winter day, before ever he came to the place where the trampled snow showed that a scurry of feet had come--and gone! Wolves' feet--and gone most amazingly! Only a little beyond he came to the lopped point of Christian's bear-spear; farther on he would see where the remnant of the useless shaft had been dropped. The snow here was dashed with blood, and the footsteps of the two had fallen closer together. Some hoarse sound of exultation came from him that might have been a laugh had breath sufficed. "O White Fell, my poor, brave love! Well struck!" he groaned, torn by his pity and great admiration, as he guessed surely how she had turned and dealt a blow.
