He travels the fastest who travels alone. Out of his chivalry he would never leave her so long as a spark of life remained in her body: her course was simply to stand the pace until the last spark went out. She could fight away unconsciousness. She knew she could; as her physical strength ebbed, she felt this new, wondrous power sweeping through her.

He travels the fastest who travels alone. Without her, his mighty strength of body and spirit might carry him to safety. It was a long chance at best, over the ice mountains; but this man who mushed before her was not of ordinary mold. The terrible training camp through which he had passed had made of him a man of steel, giving him the lungs of a wolf and a lion’s heart, and it was conceivable that, after unimagined hardship, he might make Tzar Island. There he could get together a party to rescue Lenore, and though his love for the ignoble girl was dead, his destiny would come out right after all. It was all she dared pray for now,—that he might find life and safety. But he was beaten at the start if he had to wait for her.

On and on through the night they sped, over that wonderfully smooth ice, never daring to halt: strange, wandering figures in the moonlit snow. But Bess was not to carry her brave intent through to the end. She had not counted on Ned’s power of observation. He suddenly halted, turned and looked into her face.

It was wan and dim in the pale light; and yet something about its deepening lines quickened his interest. She saw him start; and with a single syllable of an oath, reached his hand under her hood to the track of the artery at her throat. He needed to listen but an instant to the fevered pulse to know the truth.

“We’re going too fast,” he told her shortly.

“No—no!” Her tone was desperate, and his eyes narrowed with suspicion. Wrenching back her self-control she tried to speak casually. “I can keep up easily,” she told him. “I don’t feel it yet—I’ll tell you when I do. We can’t ever make it if we slow up.”

He shook his head, wholly unconvinced. “I don’t know what’s got into you, Bess. You can’t fool me. I know I feel it, good and plenty, and you’re just running yourself to death. Doomsdorf himself can’t do any more than kill us——”

“But he can——”

“We’re going to hit an easier pace. Believe me, he’s not running his heart out. He’s planning on endurance, rather than speed. I was a fool not to think about you until it began to get me.”

It was true that the killing pace had been using up the vital nervous forces of both their bodies. Ned was suffering scarcely not at all as yet, but he had caught the first danger signals. Bess was already approaching the danger point of fatigue. When Ned started on again he took a quick but fairly easy walking pace.
