“About a month later—on January 26th, to be exact, I was sitting at home reading a book, preparatory to retiring to bed. I should say that I occupy a flat, or rather maisonette, in a small house which has been divided to make two establishments. The people on the ground floor were away at that time, so that I was quite alone in the house. My housekeeper only comes in by the day. The telephone rang—I noticed the time. It was a quarter to eleven. I answered it, and a woman’s voice spoke, begging me to come instantly to a certain house on Hampstead Heath, to make a will for someone who was at the point of death.”

“Did you recognise the voice?”

“No. It sounded like a servant’s voice. At any rate, it had a strong cockney accent. I asked whether to-morrow would not be time enough, but the voice urged me to hurry or it might be too late. Rather annoyed, I put my things on and went out. It was a most unpleasant night, cold and foggy. I was lucky enough to find a taxi on the nearest rank. We drove to the address, which we had great difficulty in finding, as everything was pitch-black. It turned out to be a small house in a very isolated position on the Heath—in fact, there was no proper approach to it. I left the taxi on the road, about a couple of hundred yards off, and asked the man to wait for me, as I was very doubtful of ever finding another taxi in that spot at that time of night. He grumbled a good deal, but consented to wait if I promised not to be very long.

“I made my way to the house. At first I thought it was quite dark, but presently I saw a faint glimmer in a ground-floor room. I rang the bell. No answer, though I could hear it trilling loudly. I rang again and knocked. Still no answer. It was bitterly cold. I struck a match to be sure I had come to the right house, and then I noticed that the front door was ajar.

“I thought that perhaps the servant who had called me was so much occupied with her sick mistress as to be unable to leave her to come to the door. Thinking that in that case I might be of assistance to her, I pushed the door open and went in. The hall was perfectly dark, and I bumped against an umbrella-stand in entering. I thought I heard a faint voice calling or moaning, and when my eyes had become accustomed to the darkness, I stumbled forward, and saw a dim light coming from a door on the left.”

“Was that the room which you had seen to be illumined from outside?”

“I think so. I called out, ‘May I come in?’ and a very low, weak voice replied, ‘Yes, please.’ I pushed the door open and entered a room furnished as a sitting-room. In one corner there was a couch, on which some bed-clothes appeared to have been hurriedly thrown to enable it to be used as a bed. On the couch lay a woman, all alone.

“I could only dimly make her out. There was no light in the room except a small oil-lamp, with a green shade so tilted as to keep the light from the sick woman’s eyes. There was a fire in the grate, but it had burnt low. I could see, however, that the woman’s head and face were swathed in white bandages. I put out my hand and felt for the electric switch, but she called out:

“‘No light, please—it hurts me.’”

“How did she see you put your hand to the switch?”
