'You had better not let him go without a search; I don't like the look of him.' Accordingly Metcalfe was removed to the guard-room and his clothes examined all over to see if they concealed any letters. The guard even split in two a pack of cards which Metcalfe had in his pocket, imagining that he might have contrived to slip a piece of thin paper between the thick edges of the cardboard then used. The cards, however, had not been employed for this purpose, and after three days' confinement in a loft Metcalfe was tried by court-martial and acquitted, and given besides permission to go to the Prince. By this time, however, he had somehow discovered that Thornton had escaped from Falkirk, so he was only anxious to return to the British army as fast as he could. The Irish spy was equally desirous of taking letters to Edinburgh to some of the friends of Prince Charlie, who were to be found there, but did not know how to pass the English sentries, a difficulty easily solved by Blind Jack, who assured him that he would tell them he was going to Captain Thornton. Not far from the English outposts the two travellers met with an officer who knew Metcalfe, and informed him to his great delight that the captain was in Edinburgh, so when the sentries were passed he bade farewell to the Irishman after promising to meet him the next night, and went straight to the captain. 'You have given me a great deal of trouble,' was Metcalfe's greeting. 'Really, people might manage to come home from market without being fetched.' 'Well, so I did,' answered Thornton with a laugh. 'But what is to be done now, as I have neither clothes nor cash?' 'Oh, I can get you both!' replied Metcalfe; 'some friends I have here have often heard me speak of you, and they will trust you for payment.' And he was as good as his word, and quickly borrowed thirty pounds, which provided the captain with all the clothes he wanted. In January 1746 the Duke of Cumberland, Commander-in-Chief of the English army, arrived in Edinburgh, and as Thornton was a great friend of his, the Duke heard all his adventures and the share Blind Jack had taken in them. He then sent for Metcalfe, and being much interested in his story often watched him on the march, and noticed, to his surprise, that, by listening to the drum, Jack was able to keep step with the rest. The British forces proceeded northwards as far as Aberdeen, where the Duke suddenly determined to give a ball to the ladies and begged that Thornton would allow Metcalfe to play the country dances, as the wind instruments of the German musicians were unsuitable. It must have been rather a strange ball, as up to the last moment it was quite uncertain whether they might not have to fight instead of dance, and the invitations were only sent out at five o'clock for the company to assemble at six. Twenty-five couples were present and kept Metcalfe hard at work till two the next morning; the Duke, then about twenty-five, dancing away with the rest.
