Gunman's Reckoning by Max Brand

Fifty miles over any sort of going is a stiff march. Fifty miles uphill and down and mostly over districts where there was only a rough cow path in lieu of a road made a prodigious day's work; and certainly it was an almost incredible feat for one who professed to hate work with a consuming passion and who had looked upon an eight-mile jaunt the night before as an insuperable burden. Yet such was the distance which Donnegan had covered, and now he drove the pack mule out on the shoulder of the hill in full view of The Corner with the triangle of the Young Muddy and Christobel Rivers embracing the little town. Even the gaunt, leggy mule was tired to the dropping point, and the tough buckskin which trailed up behind went with downward head. When Louise Macon turned to him, he had reached the point where he swung his head around first and then grudgingly followed the movement with his body. The girl was tired, also, in spite of the fact that she had covered every inch of the distance in the saddle. There was that violet shade of weariness under her eyes and her shoulders slumped forward. Only Donnegan, the hater of labor, was fresh.

They had started in the first dusk of the coming day; it was now the yellow time of the slant afternoon sunlight; between these two points there had been a body of steady plodding. The girl had looked askance at that gaunt form of Donnegan's when they began; but before three hours, seeing that the spring never left his step nor the swinging rhythm his stride, she began to wonder. This afternoon, nothing he did could have surprised her. From the moment he entered the house the night before he had been a mystery. Till her death day she would not forget the fire with which he had stared up at her from the foot of the stairs. But when he came out of her father's room -- not cowed and whipped as most men left it -- he had looked at her with a veiled glance, and since that moment there had always been a mist of indifference over his eyes when he looked at her.
