allen him. I at least was sound in nerve and brain, and it was with
something of the pleasurable thrill of anticipation with which the
sportsman takes his position beside the haunt of his game that I shut
the laboratory door behind me, and partially undressing, lay down upon
the rug-covered settee.

It was not an ideal atmosphere for a bedroom. The air was heavy with
many chemical odours, that of methylated spirit predominating. Nor were
the decorations of my chamber very sedative. The odious line of glass
jars with their relics of disease and suffering stretched in front of my
very eyes. There was no blind to the window, and a three-quarter moon
streamed its white light into the room, tracing a silver square with
filigree lattices upon the opposite wall. When I had extinguished my
candle this one bright patch in the midst of the general gloom had
certainly an eerie and discomposing aspect. A rigid and absolute silence
reigned throughout the old house, so that the low swish of the branches
in the garden came softly and smoothly to my ears. It may have been the
hypnotic lullaby of this gentle susurrus, or it may have been the result
of my tiring day, but after many dozings and many efforts to regain my
clearness of perception, I fell at last into a deep and dreamless
sleep.

I was awakened by some sound in the room, and I instantly raised myself
upon my elbow on the couch. Some hours had passed, for the square patch
upon the wall had slid downwards and sideways until it lay obliquely at
the end of my bed. The rest of the room was in deep shadow. At first I
could see nothing, presently, as my eyes became accustomed to the faint
light, I was aware, with a thrill which all my scientific absorption
could not entirely prevent, that something was moving slowly along the
line of the wall. A gentle, shuffling sound, as of soft slippers, came
to my ears, and I dimly discerned a human figure walking stealthily from
the direction of the door. As it emerged into the patch of moonlight I
saw very clearly what it was and how it was employed. It was a man,
short and squat, dressed in some sort of dark-grey gown, which hung
straight from his shoulders to his feet. The moon shone upon the side of
his face, and I saw that it was chocolate-brown in colour, with a ball
of black hair like a woman's at the back of his head. He walked slowly,
and his eyes were cast upwards towards the line of bottles which
contained those gruesome remnants of
