He rode straight south, seeking no trail, but guiding their course by the stars, his right hand firmly grasping the pony's bit, and continually urging his own mount to faster pace. The one thought dominating his mind was the urgent necessity for haste--a savage determination to intercept that early train eastward. Beyond this single idea his brain seemed in hopeless turmoil, seemed failing him. Any delay meant danger, discovery, the placing of her very life in peril. He could grasp that; he could plan, guide, act in every way the part of a man under its inspiration, but all else appeared chaos. The future?--there was no future; there never again could be. The chasm of a thousand years had suddenly yawned between him and this woman. It made his head reel merely to gaze down into those awful depths. It could not be bridged; no sacrifice, no compensation might ever undo that fatal death-shot. He did not blame her, he did not question her justification, but he understood--together they faced the inevitable. There was no escape, no clearing of the record. There was nothing left him to do except this, this riding through the night--absolutely nothing. Once he had guided her into safety all was done,--done forever; there remained to him no other hope, ambition, purpose, in all this world. The desert about them typified that forthcoming existence--barren, devoid of life, dull, and dead. He set his teeth savagely to keep back the moan of despair that rose to his lips, half lifting himself in the stirrups to glance back toward her. If she perceived anything there was not the slightest reflection of it within her eyes. Lustreless, undeviating, they were staring directly ahead into the gloom, her face white and almost devoid of expression. The sight of it turned him cold and sick, his unoccupied hand gripping the saddle-pommel as though he would crush the leather. Yet he did not speak, for there was nothing to say. Between these two was a fact, grim, awful, unchangeable. Fronting it, words were meaningless, pitiable.
