But "the cat i' the adage" succeeded so far on the Tuesday in getting the better of his scruples, that he absolutely did form a plot. He did not as yet quite see his way to that security which would be indispensable;--but he did form a plot. Then came the bitter reflection that what he would do would be done for the benefit of others rather than his own. What would Lord Frederic know of his benefactor when he should come to the throne--as in such case he would do--as Marquis of Kingsbury? Lord Frederic would give him no thanks, even were he to know it,--which of course could never be the case. And why had not that woman assisted him,--she who had instigated him to the doing of the deed? "For Banquo's issue have I filed my mind," he said to himself over and over again, not, however, in truth thinking of the deed with any of the true remorse to which Macbeth was a prey. The "filing of his mind" only occurred to him because the words were otherwise apt. Would she even be grateful when she should tell herself,--as she surely would do,--that the deed had been done by the partner of her confidences? When he thought of the reward which was to come to him in payment of the intended deed something like a feeling of true conscience did arise within him. Might it not be the case that even he, callous as he was to most things, should find himself unable to go down to Appleslocombe and read himself in, as the phrase goes, as rector and pastor of the parish? He thought of this as he lay in his bed, and acknowledged to himself that his own audacity would probably be insufficient to carry him through such a struggle. But still on the morning when he rose he had not altogether rejected the idea. The young man had scorned him and had insulted him, and was hateful to him. But still why should he be the Macbeth, seeing that the Lady Macbeth of the occasion was untrue to him? In all this he was unaware how very little his Lady Macbeth had really meant when she had allowed herself in his presence to express wishes as to her stepson's death.
