"Old Jenk is worrying me, sir. He's been wandering about the ramparts to-night in a curious, crazy way, speaking to nobody, and acting silly-like. I'm pretty sure it was him as cut that line and let down the flag." "I'll talk to him to-morrow. Good-night till twelve, Ben. I'm tired, and shall be glad of my rest." "Good-night till twelve, captain," said the old soldier; and Roy went to his room, took off helmet and sword-belt, and threw himself upon a couch, to forget all his low spirits and troubles in less than a minute, falling at once into a deep sleep, from which he started at the first chime of the tower clock. The little lamp was burning dimly now on the mantelpiece, but it gave him light enough to buckle on his sword; and as he did so, the chiming and striking of the midnight hour went on in the midst of what seemed an unnatural silence, which impressed him. The next moment his helmet was on, and he stepped quickly out into the corridor, to find it full of armed men, four of whom dashed at him as his hand flew to his side, and he drew his sword. It was a vain effort; his arms were roughly grasped, and the cry he tried to raise was smothered by a hand pressed upon his mouth; while, by the light of a lantern raised on high, he saw the figure of the secretary, who stepped forward and took the sword wrenched from his hand. "Thanks, my brave young castellan," he said, mockingly. "We will take off your steel toys and gewgaws by-and-by. One word, though," he said, in a fierce whisper: "make the slightest sound, and you will be thrown into the moat. Be silent, and we will recollect that you are only a boy, and treat you as one." For answer, Roy threw all his strength into one desperate effort, wrenched his head round so that it was clear of the hand pressed upon it, and shrieked out the one word-- "Judas!" The word seemed to cut into the wretched traitor's brain; and, raising the boy's sword, he struck at him; but the blade glanced from the perfectly tempered helmet, and the next moment one who seemed to be an officer interposed. "Prisoners are not treated like that, sir," he said, sternly. "Which way now?" "This," said the secretary; and he led the way along the corridor, towards the door opening upon the court-yard.
