The letter proved to be from Campbell, and informed Frank that as there were night hawks abroad, he must hold no communication with any one lest it should lead to future trouble. The person who gave him the letter might be trusted, but that in the meantime it would be well to avoid a meeting with "R. M. C." Frank was much disappointed at this deferring of the hope of aiding his father, by recovering the papers and titles which Rashleigh had stolen. But still there was no help for it. And so, after dragging Andrew out of the corner of the shed, where he was hidden behind a barrel of feathers, he returned to the inn. Here he found the Bailie high in dispute with his quondam friend, the Lowlander Galbraith. The quarrel concerned the Duke of Argyle and the Clan Campbell, but most of all a certain freebooter of the name of Rob Roy, who, as it now appeared, they were all assembled to pursue and make an end of. North and east the passes were being held. The westland clans were out. Southward Major Galbraith was in command of a body of Lennox horse, and to a certainty Rob Roy would swing in a rope by the morrow's morn. Scarcely were the words spoken when the ordered tramp of infantry on the march was heard, and an officer, followed by two or three files of soldiers, entered the apartment. It gave Frank a thrill of pleasure to remark his English accent, after the Scotch which he had been listening to ever since he left Osbaldistone Hall. But he liked somewhat less what he was next to hear. The English officer had received instructions to place under arrest two persons, one young and the other elderly, travelling together. It seemed to him that Frank and the Bailie answered fairly well to this description. In spite of the protests and threats of the honourable magistrate, he ordered them both to follow him in his advance into the Highland country, upon which he was immediately to set out. The letter which Frank had received from the landlady of the inn, being found upon him, was held to be evidence that he had been in treasonable correspondence with Rob Roy, whose usual initials, indeed, were at the bottom of the note. Next the shock-headed Highlander who had taken the Bailie's quarrel upon him, having been captured, was brought before the officer, and commanded, on pain of being instantly hanged, to lead them to the place where he had left the Mac-Gregor. After long persuasion, some of it of the roughest sort, poor Dougal consented for five guineas to act as guide to the party of soldiers under Captain Thornton--for such was the name of the English officer. This sinful compliance of Dougal's angered the Bailie so much that he cried to the soldiers to take Dougal away, because now he deserved hanging for his treachery more than ever. This drew the retort from the Corporal who was acting as hangman, that if it were the Bailie who was going to be hanged, he would be in no such desperate hurry!
