On the 11th of the following month Grange and Lethington had already ground for complaint that, contrary to promise, ‘the town was still guarded and garrisoned as a town of war.’ A few days later they drew up a formal protest in which they stated that the Capital was occupied by companies of soldiers and townsmen, who kept watch and ward day and night, and continually used the Kirk and Tolbooth as guard-houses. Leith also, they said, was guarded as in time of war, in contravention of the abstinence. Men-at-arms were lodged upon the poor, to be fed at their expense; and in many cases the inhabitants were forbidden to enter their own houses, which had been taken possession of by the soldiery. In the beginning of September, a new agent, Killegrew, was dispatched to Scotland for the ostensible purpose of effecting a compromise between the two parties, but in reality with a view to arranging with Morton for the secret execution of Queen Mary. All that his intervention achieved was the prolongation of the truce till the 1st of January. The result of his secret mission, however, was to secure the complicity of Mar and Morton in Elizabeth’s scheme for the destruction of her rival, on condition that they should receive help from England for the subjugation of the Castilians, at the expiration of the truce. When Killegrew arrived in Scotland, the Earl of Mar was lying ill at Tantallon Castle, and it was there the English ambassador had his first interview with him. He recovered sufficiently to be removed to Stirling. On the 27th of October, it was reported to Burghley that he had been bled, and was ‘somewhat amended.’ The very next day, however, he died, with a suddenness that gave rise to a suspicion of poison. Rather less than a month later, Morton was chosen to succeed him.
