The main question is, did Macbeth murder Duncan? It was an older story in Shakspeare's time than the murder of Darnley is now, and he may have taken a false view of it. We shall approach the question by an inquiry who Duncan and Macbeth were, and in what relation they stood to each other. About the end of the eleventh century, there reigned in Scotland a king called Kenneth III. Like all the other Scottish monarchs of the period, the chroniclers have given him his own peculiar tragic history, in this wise: he was induced to poison the young prince Malcolm Duff, who might possibly show a title to the throne enabling him to compete with Kenneth's own offspring. This troubled his conscience. He "ever dreaded in his mind," in the expressive words of old Bellenden, that it "should come some time to light: and was so full of suspicion, that he believed when any man rounded to his fellow, that they spake evil of him; for it is given by nature to ilk creature, when he is guilty of any horrible crime, by impulsion of his conscience, to interpret every thing that he sees to some terror of himself." He was one night appalled by a terrific vision, and next morning making his confession, he was sentenced to a pilgrimage to the tomb of St Palladius at Fordun. When the pilgrimage was over, he was invited to partake of the hospitalities of a lady named Fenella--a very neat name for a romance--at her fortalice of Fettercairn. In the civil conflicts or the administration of justice during his reign, some of the relations of this lady had been slain; among the rest her son. Having got the king into her toils, she resolved to put him to death; and the method which the chroniclers make her adopt, shows a superfluous ingenuity ridiculous enough to strip a murder of all its horrors. Kenneth was taken to see a tower of the castle "quhilk was theeket with copper, and hewn with maist subtle mouldry of sundry flowers and imageries, the werk so curious, that it exceeded all the stuff thereof." In the middle of this tower stood an image of Kenneth himself, in brass, holding in his hand a golden apple studded with costly gems. "That image," said the lady, "is set up in honour of thee, to show the world how much I honour my king; the precious apple is intended for a gift for the king, who will honour his poor subject by taking it from the hand of the image." Now matters were so arranged, that the removal of the apple caused certain springs to touch the triggers of a series of bent cross-bows pointed to the spot, and so, when the unsuspecting monarch went to take the gift, a whole sheaf of arrows penetrated to his heart. On the death of this king, though he left a son called Malcolm, the succession went to a rival line. His immediate successor was Constantine, who was killed by another Kenneth, called IV., who in his turn was killed by Malcolm, who thus regained the throne his father had filled. "The gracious Duncan" was the son of a daughter of this Malcolm. His father,
