Thomas shuddered; he had forgotten Felix, but as he heard these words he could no longer delay looking at the man who had offered to stand his surety for the performance of the unholy deed his father exacted from him. Turning, he saw a man who in any place and under any roof would attract attention, awake admiration and--yes, fear. He was not a large man, not so large as himself, but the will that expressed itself in frenzy on his father's lips showed quiet and inflexible in the gray eye resting upon his own with a power he could never hope to evade. As he looked and comprehended, a steel band seemed to compress his heart; yet he was conscious at the same time that the personality before which he thus succumbed was as elegant as his own and as perfectly trained in all the ways of men and of life. Even the air of poverty which had shocked him in his father's person and surroundings was not visible here. Felix was both well and handsomely clad, and could hold his own as the elder brother in every respect most insisted upon by the Parisian gentleman. The long and, to Thomas, mysterious curtain of dark-green serge which stretched behind him from floor to ceiling threw out his pale features with a remarkable distinctness, and for an instant Thomas wondered if it had been hung there for the purpose of producing this effect. But the demand in his brother's face drew his attention, and, bowing his head, he stammered: "I am at your command, Felix. I am at your command, father. I cannot say more. Only remember that I never saw Evelyn, that she died before I was born, and that I----" But here Felix's voice broke in, kind, but measured: "Perhaps there is some obstacle we have not reckoned upon. You may already love some woman and desire to marry her. If so, it need be no impediment----" But here Thomas's indignation found voice. "No," said he; "I am heart-whole save for a few lingering fancies which are fast becoming vanishing dreams." He seemed to have lived years since entering this room. "Your heart will not be disturbed now," commented Felix. "I have seen the girl. I went there on purpose a year ago. She's as pale as a snow-drop and as listless. You will not be obliged to recall to mind the gay smiles of Parisian ladies to be proof against her charms." Thomas shrugged his shoulders. "She must be made to know the full intoxication of hope," Felix proceeded in his clear and cutting voice. "To realize despair she must first experience every delight that comes with satisfied love. Have you the skill as well as heart to play to the end a role which will take patience as well as dissimulation, courage as well as subtlety, and that union of will and implacability which finds its food in tears and is strengthened, rather than lessened, by the suffering of its victim?" "I have the skill," murmured Thomas, "but----"
