But the crowning act of guilt was the murder of the unfortunate Archbishop. On the 3d of May 1679, a party of the Fife non-conformists were prowling near the village of Ceres, on the outlook, it is said, for Carmichael the Sheriff-substitute of the county, against whom they had sworn vengeance if he should ever fall into their hands. This party consisted of twelve persons, at the head of whom were John Balfour of Kinloch, better known by his _soubriquet_ of Burley, and his brother-in-law, David Hackstoun of Rathillet. Balfour, whose moral character had never stood high, though his religious fanaticism was undoubted, had been at one time chamberlain to the Archbishop, and had failed to account for a considerable portion of the rents, which it was his official duty to levy. Hackstoun, whose earlier life had been in little accordance with the ostensible tenets of his party, was also in debt to the Archbishop, and had been arrested by the new chamberlain. "These two persons," says Mr Lawson, "had most substantial reasons for their rancour and hatred towards the Archbishop, apart from their religious animosities." It does not seem to be clearly ascertained, whether Carmichael was the real object of their search, or whether their design from the first had been directed against the person of the Primate. It would appear, however, from the depositions taken shortly after the murder, that the deed had been long premeditated, and that three days previously some of the assassins had met at a house in Ceres and concerted their plans. The incumbent of Ceres, the Rev. Alexander Leslie, was also to have been made a victim if found in company with the Prelate. Fortunately for himself, Carmichael eluded their search, but towards evening the carriage of the Archbishop was seen approaching the waste ground near St Andrews, which is still known by the name of Magus Muir. A hurried council was then held. Hackstoun, probably from some remnant of compunction, declined to take the lead; but Balfour, whose bloodthirsty disposition was noted even in those unhappy times, assumed the command, and called upon the others to follow him. The consummation of the tragedy can best be told in the words of the historian already quoted. "When the Primate's servants saw their master followed by a band of men on horseback, they drove rapidly, but they were overtaken on the muir about three miles west of St Andrews; the murderers having previously satisfied themselves, by asking a female domestic of the neighbouring farmer, who refused to inform them himself, that it was really the Archbishop's coach.
