Equally silent, the girl sat looking after him. She did not move. She did not make a sound. Not until the horse turned in at the C-C ranch house, until the buildings hid the owner from view, did her eyes leave him. Then, as if compelled by an instinct, she looked away over the prairie, away where the last time she had glanced a tiny black dot stood out against the intense blue sky. But look as she might she could not find it. It was there no more. It had been for long; but now was not. Clean as though drawn by a crayon on a freshly washed blackboard, the unbroken horizon line stretched out in a great circle before her eyes. With no watcher save the grey wolf staring forth from the stable doorway, she was alone with her thoughts. CHAPTER XVI THE RECKONING It was later than usual when How Landor returned that evening, and as he came up the path that led from the stable, he shuffled his feet as one unconsciously will when very weary. He was wearing his ready-made clothes and starched collar; but the trousers were deplorably baggy at the knees from much riding, and his linen and polished shoes were soiled with the dust of the prairie. Supper was waiting for him, a supper hot and carefully prepared. Serving it was a young woman he had not seen for long, a young woman minus the slightest trace of listlessness, with a dash of red ribbon at belt and throat, and a reflection of the same colour burning on either cheek. A young woman, moreover, who anticipated his slightest wish, who took his hat and fetched his moccasins, and when the meal was over brought the buffalo robes and stretched them carefully on the gently sloping terrace just outside the ranch house door. Meanwhile she chatted bubblingly, continuously; with a suggestion of the light-hearted gaiety of a year before. To one less intimately acquainted with her than the man, her companion, she would have seemed again her old girlish self, returned, unchanged; but to him who knew her as himself there was now and then a note that rang false, a hint of suppressed excitement in the unwonted colour, an abnormal energy bordering on the feverish in her every motion. Not in the least deceived was this impassive, all-observing human, not in the least in doubt as to the cause of the transformation: yet through it all he gave no intimation of consciousness of the unusual, through it all he smiled, and smiled and smiled again. Never was there a more appreciative diner than he, never a more attentive, sympathetic listener. He said but little; but that was not remarkable. He had never done so except when she had not. When he looked at her there was an intensity that was almost uncanny in his gaze; but that also was not unusual. There was ever a mystery in the depths of his steady black eyes. Never more himself, never outwardly more unsuspicious was the man than on this occasion; even when, the meal complete, the girl had led him hand in hand out of doors, out into the soft spring
