At first this peculiarity gave me no little alarm, as she would often rise in the middle of the night, light a candle and wander all over the house, and I was afraid that some night she would set the house on fire.

However, no accident ever occurred, and to my surprise I found that she seemed just as cautious in her sleep as if she had been in her waking state, always shading the flame with her hand and using such extreme caution when passing near the curtains or anything else at all likely to catch fire, that I used to doubt sometimes if she really could be asleep.

Being warned by the doctor never to address her or touch her whilst in this state, lest the shock should be too great for her, I, at first, used to follow her with my eyes about the room, and if she left the chamber, I generally used to rise and follow softly after, at some distance, lest an accident should befall her. But finding soon that she was just as certain of her footing in her sleep as in her waking moments, I began to abandon my fears, and thought no more of this peculiarity.

Indeed, as she was in the habit of rising every other night, I soon felt far too sleepy to trouble myself about her. But soon this strange power in her began to develop itself, and to take a stranger and more interesting form.

She would now get up at night, sit herself down at a table, take pen, ink, and paper, and fill sheet after sheet with close writing and elegant composition. This was particularly the case if she had left a task uncompleted during the day. In the morning it was sure to be found finished, and generally better done than if it had been accomplished during her hours of waking; nor was she herself conscious of it until she examined her exercise the next morning.

If I perchance should have an uncompleted task on hand, she would invariably finish mine before her own. But this phenomenon in my young friend, however strange and unaccountable it may seem, sinks into utter insignificance before a far more terrible one which I am now about to describe.

You may think I exaggerate, gentlemen, or that it was the effect of my own over-wrought fancy, produced by sleepless nights of watching over my young friend, but there are witnesses living yet who saw what I saw, and who are ready to give their testimony. The doctor of this village, together with his assistant, the rector, and two women living close by, are among these I speak of, besides others. Let them speak for themselves if you will not believe my word.

The phenomenon to which I have above alluded was the power, if I may so call it, of dividing herself in two, or becoming two separate beings; that is to say, of making a duplicate of herself. This extraordinary and fearful gift had evidently been noticed by others before it fell under my own observation, since for a long time previous to seeing it myself it was reported throughout the village that Claribel Falkland had appeared in two places at the same time.

To this, however, as to all other village gossip, I paid no attention, knowing well how trifles get exaggerated after passing through many mouths, and how sometimes reports are circulated without an atom of truth for their foundation. I can only tell you, however, gentlemen, what I saw with my own eyes, believe it, or not, as you will. One morning, then, after returning home from school, Claribel having been unable to attend from some slight indisposition, I entered the room suddenly where my friend was seated. I remember, too, that I had never felt in better health in all my life, when there, to my utter consternation, was not only my friend, seated as was her wont, in an easy chair, with her head resting on her hand, but another figure, the exact counterpart of herself, a duplicate Claribel, leaning over the back of her arm-chair, exactly in the same position as my friend happened to be at the time.

I remained at the door, my eyes and mouth wide open, in mute horror, unable to advance a step or utter an exclamation, until my friend, looking up and inquiring the reason of my surprise, the figure behind the chair instantly vanished. I then proceeded to relate to her the vision, which she, however, smiled at and affected to treat as a temporary delusion on my part, the result of indigestion or disordered state of my nerves. I persisted that I was in the most perfect health, and that I had seen what I chose to style her "double."
