... Yet I do not doubt but that you shall see the day and time that you shall pray for my soul, for the great good that I have done to you, and to all in this realm of Scotland, that I have thus slain and delivered you of so cruel a tyrant...
The retreat from Roxburgh exposed the king to questions regarding his control over his subjects, his military competence and his diplomatic abilities yet he remained determined to continue with the war against England. Just two months after the Roxburgh debacle, James called a general council in October 1436 to finance further hostilities through more taxation. The estates firmly resisted this and their opposition was articulated by their speaker Sir Robert Graham, a former Albany attendant and a servant of the king's uncle, Walter Stewart, Earl of Atholl. The council then witnessed an unsuccessful attempt by Graham to arrest the king resulting in the knight's imprisonment followed by banishment but James did not see Graham's actions as part of an extended threat. In February 1437 James lodged at the Blackfriars monastery on the outskirts of Perth accompanied by the queen but separated from most of their servants. The king's cousin Sir Robert Stewart, heir to his grandfather Walter, Earl of Atholl, was chamberlain of the royal household and used his privileged position to allow a small band of former Albany adherents led by Robert Graham to enter the building. James was alerted to the men's presence after servants discovered their approach giving the king time to hide in a sewer tunnel but with its exit recently blocked off to prevent tennis balls getting lost, James was trapped and killed. Although wounded, the queen managed to escape and sent a directive ahead to Edinburgh for the now James II to be shielded from any widening of the conspiracy and had the boy king's custodian, the pro-Atholl John Spens, removed from his post and replaced by the trusted John Balfour. The regicide of James I came so unexpectedly that a period of disorder took hold before James II was crowned at Holyrood Abbey on 25 March 1437 but it was not until early May that the main conspirators, Walter of Atholl, his grandson Robert Stewart and Robert Graham were gruesomely executed.
King James' embalmed heart was likely taken on pilgrimage to the Holy Land following his interment at Perth Charterhouse, as the Exchequer Rolls of Scotland for 1443 note the payment of £90 to cover the costs of a knight of the Order of St John who had returned it to the Charterhouse from the Island of Rhodes.
