Never before had Christian so rejoiced in his powers. The gift of speed, and the training of use and endurance were priceless to him now. Though midnight was hours away, he was confident that, go where that Fell Thing would, hasten as she would, she could not outstrip him nor escape from him. Then, when came the time for transformation, when the woman's form made no longer a shield against a man's hand, he could slay or be slain to save Sweyn. He had struck his dear brother in dire extremity, but he could not, though reason urged, strike a woman. For one mile, for two miles they ran: White Fell ever foremost, Christian ever at equal distance from her side, so near that, now and again, her out-flying furs touched him. She spoke no word; nor he. She never turned her head to look at him, nor swerved to evade him; but, with set face looking forward, sped straight on, over rough, over smooth, aware of his nearness by the regular beat of his feet, and the sound of his breath behind. In a while she quickened her pace. From the first, Christian had judged of her speed as admirable, yet with exulting security in his own excelling and enduring whatever her efforts. But, when the pace increased, he found himself put to the test as never had he been before in any race. Her feet, indeed, flew faster than his; it was only by his length of stride that he kept his place at her side. But his heart was high and resolute, and he did not fear failure yet. So the desperate race flew on. Their feet struck up the powdery snow, their breath smoked into the sharp clear air, and they were gone before the air was cleared of snow and vapour. Now and then Christian glanced up to judge, by the rising of the stars, of the coming of midnight. So long--so long! White Fell held on without slack. She, it was evident, with confidence in her speed proving matchless, as resolute to outrun her pursuer as he to endure till midnight and fulfil his purpose. And Christian held on, still self-assured. He could not fail; he would not fail. To avenge Rol and Trella was motive enough for him to do what man could do; but for Sweyn more. She had kissed Sweyn, but he should not die too: with Sweyn to save he could not fail. Never before was such a race as this; no, not when in old Greece man and maid raced together with two fates at stake; for the hard running was sustained unabated, while star after star rose and went wheeling up towards midnight, for one hour, for two hours. Then Christian saw and heard what shot him through with fear. Where a fringe of trees hung round a slope he saw something dark moving, and heard a yelp, followed by a full horrid cry, and the dark spread out upon the snow, a pack of wolves in pursuit.
