ded.

Never losing my hold for an instant, I slipped from the bed to the
floor, dragging my captive with me. I had but a few steps to make to
reach the gas-burner; these I made with the greatest caution, holding
the creature in a grip like a vice. At last I got within arm's length of
the tiny speck of blue light which told me where the gas-burner lay.
Quick as lightning I released my grasp with one hand and let on the full
flood of light. Then I turned to look at my captive.

I cannot even attempt to give any definition of my sensations the
instant after I turned on the gas. I suppose I must have shrieked with
terror, for in less than a minute afterward my room was crowded with the
inmates of the house. I shudder now as I think of that awful moment. _I
saw nothing!_ Yes; I had one arm firmly clasped round a breathing,
panting, corporeal shape, my other hand gripped with all its strength a
throat as warm, and apparently fleshly, as my own; and yet, with this

I wonder that I did not faint or go mad on the instant. Some wonderful
instinct must have sustained me; for absolutely, in place of loosening
my hold on the terrible Enigma, I seemed to gain an additional strength
in my moment of horror, and tightened my grasp with such wonderful force
that I felt the creature shivering with agony.

Just then Hammond entered my room at the head of the household. As soon
as he beheld my face--which, I suppose, must have been an awful sight to
look at--he hastened forward, crying, "Great Heaven, what has happened?"

"Hammond! Hammond!" I cried, "come here. Oh, this is awful! I have been
attacked in bed by something or other, which I have hold of; but I can't
see it--I can't see it!"

Hammond, doubtless struck by the unfeigned horror expressed in my
countenance, made one or two steps forward with an anxious yet puzzled
expression. A very audible ti
