CHAPTER XXIX.
THE MYSTERIOUS CHAMBER.

Opening a movable shelf in the bookcase, he disclosed a narrow passage, along which they proceeded till they came to a small back staircase, evidently communicating by a small outlet with the moat.

Mounting this staircase, Sir Richard unfastened a door, which admitted them to a dark corridor. From its appearance it was evident that this part of the mansion was shut up.

A stifling sensation, caused by the close, oppressive atmosphere, affected Atherton, and vague terrors assailed him. Two doors faced them. Sir Richard opened one of the doors, and led his companion into an antechamber, the furniture of which was mouldering and covered with dust.

A door communicating with an inner room stood ajar. After a moment's hesitation Sir Richard passed through it, and was followed by Atherton.

The chamber was buried in gloom, but on a window-shutter being opened a strange scene was disclosed. At the further end of the apartment stood an old bedstead, which seemed fully prepared for some occupant, though it could not have been slept in for many years. Quilt and pillow were mildewed and mouldering, and the sheets yellow with age. The hangings were covered with dust. Altogether, the room had a ghostly look.

For some moments Atherton could not remove his gaze from that old bed, which seemed to exercise a sort of fascination, but when he looked at Sir Richard, he was appalled by the terrible change that had come over him.

He looked the picture of horror and despair. His pallid countenance was writhen with anguish, and his limbs shook. A deep groan burst from his labouring breast.

"The hour is near at hand," he muttered, in tones scarcely human. "But I am not yet ready. Spare me till my task is finished!"

With a ghastly look he then added to Atherton: "The whole scene rises before me as it occurred on that dreadful night. The room is hushed and quiet, and within that bed a child is peacefully slumbering on his mother's breast. A masked intruder comes in—admitted by the nurse, who has betrayed her mistress. Unmoved by a picture of innocence that might have touched any heart less savage than his own, he snatches up the child, and is bearing it off when the mother awakes. Her piercing shriek still rings through my ears. I cannot describe what follows—but 'tis soon over—and when the worse than robber departs with his prize, he leaves the wretched mother lying senseless on the floor, and the nurse dead—slain by his ruthless hand!"
