Ignorant of what had passed—that the fire on his hearth was extinguished—and that his household had been driven forth like beasts of prey—Rob Roy, after failing to procure in Glasgow a sum requisite to gratify the avarice of Montrose, appeared one afternoon at the residence of the latter, the castle of Mugdock, which is nine miles distant from Glasgow, and is situated in Strathblane.

The valets muttered among themselves of what their titled master had done, and marvelled what might be the object of this visit from MacGregor; the latter, especially since his inroad into Kippen, had been somewhat used to be treated with a respect that was not unmingled with fear, so the sudden interest his appearance excited was unnoticed by him, as he was ushered into the library.

The castle of Mugdock, now a ruin, was then a regularly fortified tower. It is of great antiquity, and was protected on the east and north by the water of a lake, which was drawn round it in the manner of a fosse.

The central keep or donjon was surrounded by a barbican, built so as to form an obtuse angle with the latter, so that a cross shower of missiles would protect the arched gateway from any besiegers who might assail it, for defence was the first principle of Scottish architecture in the olden time.

Through the grated windows of the library poor Rob gazed wistfully down Strathblane, "the vale of the warm river," as it is named in the figurative language of his native country. He could see the wooded landscape stretching to the westward far away, the gentle uplands, the pine thickets, the shining lochlets and the winding stream; the insulated cone of Dumgoaic, covered to its summit with waving foliage, and in the distance, closing the familiar view, the vast outline of Ben Lomond, that overshadowed its lake of the Twenty-four Isles, and looked down on Inversnaid, where, as he fondly believed, Helen, their little ones, MacAleister, and the household awaited his return!

Alas! how little he knew of all that had happened there within the last few weeks; and as little dared his titled host to tell him.

A step fell on his ear, as a person in high-heeled riding-boots, with gilt maroquin gambadoes and gold spurs, trod on the polished oak floor. Rob turned, and found himself face to face with the chief of "the gallant Grahams," the Duke of Montrose.

The latter was not a little startled on finding himself, during such a crisis in their affairs, confronted by a man of such known resolution as the Red MacGregor, so he blushed redly to the roots of his ample periwig.

He wore the square-cut coat with buckram skirts and the long-flapped waistcoat of Queen Anne's reign. These were of dark blue silk, covered with gold embroidery, and he looked every way the great-grandson of the High Cavalier Marquis, whose portrait, by Anthony Vandycke, in wig and armour, with sword and scarlet baton, hung upon the wall—the same great Montrose who had been so cruelly butchered by the Covenanters in 1650.

As the duke entered, he had in his hand a newspaper, which he hastily crushed and concealed in his pocket, changing colour as he did so, for that identical paper was the Edinburgh Evening Courant, containing the advertisement offering a reward for Rob's seizure, dead or alive, a copy of which Grahame of Killearn had just sent to Mugdock by a special messenger.
