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 humanity. He seemed to examine each jar with attention, and then to pass on to the next. When he had come to the end of the line, immediately opposite my bed, he stopped, faced me, threw up his hands with a gesture of despair, and vanished from my sight.

I have said that he threw up his hands, but I should have said his arms, for as he assumed that attitude of despair I observed a singular peculiarity about his appearance. He had only one hand! As the sleeves drooped down from the upflung arms I saw the left plainly, but the right ended in a knobby and unsightly stump. In every other way his appearance was so natural, and I had both seen and heard him so clearly, that I could easily have believed that he was an Indian servant of Sir Dominick's who had come into my room in search of something. It was only his sudden disappearance which suggested anything more sinister to me. As it was I sprang from my couch, lit a candle, and examined the whole room carefully. There were no signs of my visitor, and I was forced to conclude that there had really been something outside the normal laws of Nature in his appearance. I lay awake for the remainder of the night, but nothing else occurred to disturb me.

I am an early riser, but my uncle was an even earlier one, for I found him pacing up and down the lawn at the side of the house. He ran towards me in his eagerness when he saw me come out from the door.

"Well, well!" he cried. "Did you see him?"

"An Indian with one hand?"

"Precisely."

"Yes, I saw him"--and I told him all that occurred. When I had finished, he led the way into his study. "We have a little time before breakfast," said he. "It will suffice to give you an explanation of this extraordinary affair--so far as I can explain that which is essentially inexplicable. In the first place, when I tell you that for four years I have never passed one single night, either in Bombay, aboard ship, or here in England without my sleep being broken by this fellow, you will understand why it is that I am a wreck of my former self.
