"Lady St. Elan was a very young wife; a soft-eyed, timid creature; her mother had died during her daughter's infancy, and her father (an officer of high rank in the army) being abroad, a lady whom we shall call Sabina, by whom she had been educated, accompanied her beloved pupil, now Lady St. Elan, to this new home. The death of Lady St. Elan's father, and the birth of a daughter, eventually mingled rejoicing and mourning together, while great anxiety was felt for the young mother, whose recovery was extremely tedious. The visits of eminent physicians, who were sent for from great distances, evinced the fears which were still entertained, even when the invalid roamed once more in the pleasant garden and woods around.

She was suddenly awakened by a curious kind of sound in the room, accompanied by a half-stifled jeering laugh. She knew not how long sleep had lulled her in oblivion, but when Sabina turned round to see from whence the sound proceeded, imagine her horror and dismay at beholding Lady St. Elan standing near the door, sharpening a large knife on her slipper, looking wildly round now and then, muttering and jibing. "'Not sharp enough yet--not sharp enough yet,' she exclaimed, intently pursuing her occupation. "Sabina felt instinctively, that this was no practical _joke_; she knew instinctively the dread reality--by the maniac's eye--by the tone of voice--and she sprang from the bed, darting towards the door.
