The rider in the lead had driven his or her horse too hard in the beginning, leaving no recovery of wind. Lambert remarked its weariness as it took the next hill, laboring on in short, stiff jumps. At the top the rider held in, as if to let the animal blow. It stood with nose close to the ground, weariness in every line. The sky was bright beyond horse and rider, cut sharply by the line of the hill. Against it the picture stood, black as a shadow, but with an unmistakable pose in the rider that made Lambert's heart jump and grow glad. It was Grace; chance had been kind to him again, leading him in the way his heart would have gone if it had been given the choice. She looked back, turning with a hand on the cantle of her saddle. He waved his hand, to assure her, but she did not seem to read the friendly signal, for she rode on again, disappearing over the hill before he reached the crest. He plunged down after her, not sparing his horse where he should have spared him, urging him on when they struck the level again. There was no thought in him of Whetstone now--only of Grace. He must overtake her in the quickest possible time, and convince her of his friendly sympathy; he must console and comfort her in this hour of her need. Brave little thing, to draw him off that way, to keep on running into the very edge of night, that wild country ahead of her, for fear he would come close enough to recognize her and turn back to help the sheriff on the true trail. That's what was in her mind; she thought he hadn't recognized her, and was still fleeing to draw him as far away as possible by dark. When he could come within shouting distance of her, he could make his intention plain. To that end he pushed on. Her horse had shown a fresh impulse of speed, carrying her a little farther ahead. They were drawing close to the hills now, with a growth of harsh and thorny brushwood in the low places along the runlets of dry streams. Poor little bird, fleeing from him, luring him on like a trembling quail that flutters before one's feet in the wheat to draw him away from her nest. She didn't know the compassion of his heart, the tenderness in which it strained to her over the intervening space. He forgot all, he forgave all, in the soft pleading of romance which came back to him like a well-loved melody. He fretted that dusk was falling so fast. In the little strips of valley, growing narrower as he proceeded between the abrupt hills, it was so nearly dark already that she appeared only dimly ahead of him, urging her horse on with unsparing hand. It seemed that she must have some objective ahead of her, some refuge which she strained to make, some help that she hoped to summon.
