An accidental circumstance was the cause of his irresolution. He used to walk frequently on the moss where the Laird Fisher sunk his shaft. In the beck that ran close to the disused headgear he would wade for an hour early in the summer morning. One day he saw the old laird's daughter washing linen at the beck-side. He remembered her as a pretty, prattling thing of ten or eleven. She was now a girl of eighteen, with a pure face, a timid manner, and an air that was neither that of a woman nor of a child. Her mother was lately dead, her father spent most of his days on the fell (some of his nights also when the charcoal was burning), and she was much alone. Hugh Ritson liked her gentle replies and her few simple questions. So it came about that he would look for her in the mornings, and be disappointed if he did not catch sight of her good young face. Himself a silent man, he liked to listen to the girl's modest, unconnected talk. His stern eyes would soften at such times to a sort of caressing expression. This went on for months, and in that solitude no idle tongue was set to wag. At length Hugh Ritson perceived that the girl's heart was touched. If he came late he found her leaning over the gate, her eyes bent down among the mountain grasses at her feet, and her cheeks colored by a red glow. It is unnecessary to go further. The girl gave herself up to him with her whole heart and soul, and he--well, he found the bulwarks with which he had surrounded himself were ruined and down. Then the awakening came, and Hugh learned too late that he had not loved the simple child, by realizing that with all the ardor of his restrained but passionate nature he loved another woman. So much for the first complication in the tragedy of this man's life. The second complication was new to his consciousness, and it was at this moment conspiring with the first to lure him to consequences that are now to be related. The story which Mr. Bonnithorne had told of the legacy left by Greta's father to a son by one Grace Ormerod had come to him at a time when, owing to disappointment and chagrin, he was peculiarly liable to the temptation of any "honest trifle" that pointed the way he wished to go. If the Grace Ormerod who married Lowther had indeed been his own mother, then--a thousand to one--Paul was Lowther's son. If Paul was Lowther's son he was also half brother of Greta. If Paul was not the son of Allan Ritson, then he himself, Hugh Ritson, was his father's heir. In the present whirlwind of feeling he did not inquire too closely into the pros and cons of probability. Enough that evidence seemed to be with him, and that it transformed the world in his view.
