The capture of his sister by Redhall, and the certainty that she too was confined in the same mansion among the trained minions and obsequious vassals of this arch conspirator, sufficiently informed him that his ancient enemy had some ulterior motive, which he could not at that time fathom. Daring as he was, and courageous to a fault, the first thoughts of the young earl were those of terror for his sister, and some little concern for himself. He now saw and regretted, unavailingly regretted, his rashness and folly, in venturing within the walls of Edinburgh at such a time, when the tidings of his recent raid on the borders were fresh in the minds of the people; and still more did he deplore his second folly, in continuing to abide there, as if in defiance of suspicion and of fate: thus selfishly compromising the safety of his dearest friends as well as his own. "I must have been mad, and Vipont was worse than mad to permit me! Let me sleep if I can," thought he, "fresh energies will come with slumber; and I, who have escaped from English Norham, and from the castle of Stirling, too, where once old Barncleugh had me fast in the Douglas chamber, will surely find a passage from this house--or the devil's in it!--and adieu my plans of vengeance for a time." And thus, acting upon principle, the light-hearted young noble, whose bold heart had never known either fear or despair, lay down on the stone floor of his prison, closed his eyes, and courted sleep as if nothing had happened; and sleep came; but his slumbers were a mere nightmare, so full were they of hideous dreams, buffets, and combats; and, more than once, he started with the certainty that he had heard his sister's cry. "Bah!" said he, "let me sleep. She is her mother's daughter, and hath too much of Black Douglas and the devil in her, to endure insult from such a poor hang-dog as Redhall! Besides, if he dared to----" and he felt a gleam pass over his eyes in the dark, at the idea that occurred to him. At an early hour Lord Ashkirk awoke, and proceeded at once to the examination of his prison. The walls and arched roof were of massive and unplastered stone; the floor was paved; the window and the chimney were grated; while the door, which he sounded with his hand, seemed a mass as solid as could be formed of oak planks and iron bolts. "Ten devils!" thought he; "at Norham I had the tongue of a waist buckle, and at Stirling a spur of steel; but here are neither buckle nor spur, knife nor nail, to loosen a stone or saw a stanchel." Between the trees he could see the rising sun gilding the top of Arthur's Seat. The solitary window, which was little more than ten inches square, was crossed by three bars built into the stone; he saw with satisfaction that it was only about fifteen feet from the ground, for his chamber was on the second vaulted story. "Good!" said he; "this wall is not like the rock of Stirling; but there I stole the cord of the flagstaff."
