Sir William refused to be satisfied with the obvious evasion, and he met it with a bold and vigorous measure. Seeing that it was really intended to bring Maitland and Balfour to trial for their lives he demanded that Morton and Archibald Douglas should be dealt with in the same manner. He charged them with being ‘upon the council, and consequently art and part of the King’s murder.’ In support of the accusation he offered to meet them in single combat with Lord Herries as his fellow-champion. This stayed the proceedings against the two prisoners for a while. Still protesting that he was a helpless and unwilling agent in the matter of their impeachment Murray informed Kirkcaldy that he intended to send Balfour to St Andrews, and to bring Lethington to Edinburgh for the purpose of entrusting him to the safe-keeping of the Governor of the Castle. At the same time, however, Grange received information that this apparent concession hid a treacherous plot against himself. It was intended to make the Secretary an instrument to draw his friend, the Governor, from the Castle into the town, under pretence of handing the prisoner over to him; and then to retain him until the fortress had been given over to Drumwhazel. Kirkcaldy was subsequently to be sent home, and to be appeased with a gift of the Priory of Pittenweem.
According to Melville, Morton had devised a more unscrupulous plot, with a view to revenging himself upon Kirkcaldy. ‘He had appointed four men to slay Grange at the entry of the Regent’s lodging, without the Regent’s knowledge.’ But the Governor had a scheme of his own, which effectually thwarted those of his two adversaries. Arguing that if, as he declared, the Regent had really been coerced into sanctioning the arrest of Lethington, he would be glad of his escape; but that if, on the contrary, he were playing a double game, his disappointment at losing his prisoner would expose his treachery, the Laird of Grange resolved to rescue Maitland from the hands of his enemies.
On his arrival in Edinburgh the Secretary was committed to the custody of Alexander Hume of North Berwick. That same evening, about ten o’clock, Kirkcaldy went to Hume with an order bearing what purported to be the Regent’s signature. Hume knew that Murray and the Laird had but lately been on terms of the closest friendship; but he does not appear to have been aware of their more recent estrangement and antagonism. Suspecting no deception, and very possibly unacquainted with the Regent’s handwriting, he assumed the genuineness of the document presented to him, and allowed Maitland to be quietly conveyed to the Castle.
When Murray and his friends learnt that the Secretary was no longer in their power they were in great perplexity, ‘supposing all their counsels to be disclosed.’ It was thought best, however, that the Regent should cover his anger for the time, and that he should take the earliest opportunity of calling upon Grange at the Castle as though nothing had happened. This he did the very next day. But in his anxiety to deceive the Governor he protested too much, and gave him more fair words than he was wont to do, ‘which Grange took in evil part.’
The Castle was becoming the headquarters of Murray’s opponents. He had, prior to Maitland’s arrest, induced the Duke of Chastelherault and Lord Herries to come to Edinburgh with a view to discussing the position of affairs, and had then handed them as prisoners to the custody of the Governor. Grange had duly received them, but he treated them as friends and as guests, and protested against the treachery of which they had been the victims. John Wood, an ardent partisan of the Regent’s, was sent to the Castle for the purpose of appeasing and conciliating the Governor. The substance of their conversation, as reported by Melville, goes far to explain Kirkcaldy’s attitude towards the party of which he had once been a zealous supporter. ‘I marvel at you,’ said Wood, ‘that you will be offended at this; for how shall we, who are my Lord’s dependers, get rewards, but by the wreck of such men?’—‘Yea,’ replied Grange, ‘is that your holiness? I see nothing among you but envy, greediness, and ambition; whereby you will wreck a good Regent, and ruin the country.’
In spite of Murray’s assumed indifference, Lethington’s escape caused him the most grievous disappointment and annoyance; and it was evident that he and Grange were gradually being carried further apart. With a view to preventing an open rupture between them, Melville devised a plan, which he took it on himself to lay before the Regent. He suggested that Lethington should retire to France, and that after his friend’s departure, Kirkcaldy should, of his own accord, resign his command of Edinburgh Castle. The Regent, however, still protested that he bore Maitland no ill-will, and had no wish to drive him into exile. As to Grange, he said he had too many obligations to him, and too great proofs of his fidelity to mistrust him. It had never been his intention, he again declared, to take the Castle from him; and if it were not in his keeping already, he would entrust it to him rather than to any other. He even went further than that, and denied that he entertained any suspicion of either Grange or the Secretary. In proof of the sincerity of his words, he went up to the Castle and ‘conferred friendly with them of all his affairs, with a merry countenance, and casting in many purposes, minding them of many straits and dangers they had formerly been together engaged in.’ But both Kirkcaldy and Maitland were too well acquainted with him, and had too long ‘been his chief advisers under God,’ not to detect the violent effort which this show of friendship cost him. No good to either party resulted from the interview. Indeed, it is scarcely possible to doubt that an irremediable breach was only prevented by Murray’s tragic and untimely end. He was shot by Bothwellhaugh on the 23rd of January 1569. Political differences were forgotten in the presence of death; and Kirkcaldy’s grief at his former friend and comrade’s untimely fate was heartfelt and sincere. When Murray’s body was solemnly carried to its resting-place in the Cathedral of St Giles, he was amongst those who came to pay him the last tribute of respect. It was he who, bearing the banner of the murdered Earl, headed the mournful procession from Holyrood to the church.
