We went together straight back to Number 190, and I think he had some misgivings about entering the house with me alone, but I reassured him by reminding him that an old lady was dying within; as it was he made me go first.

"I had no idea any one lived here at all," he remarked, as I lighted him along the passage to the stairs by means of wax vestas, of which I fortunately had a supply, for there was no candle in the hall. "I always thought this house was shut up. But still I have only been here just over twelve months."

"I think you will find," I said, as we got firmly on the basement floor, and saw the reflection of my candle which I had left on the table in the sitting-room, "that there are a good many surprises in this house."

"Now," I continued as we entered the room, "the old lady is lying in there. I will take this candle and show you the way." I led the way into the room, and held the candle aloft, with a shudder at what I expected to see there.

The bed was empty.

I rubbed my eyes and looked again.

No, there was nothing there; the bed looked rather rumpled, but there was no sign whatever of the old lady.

"Well," remarked the doctor sharply—he had followed closely at my heels—"where is your murdered old lady?"

I looked round the bedroom helplessly.

"I would take the most solemn oath," I said steadfastly, "that I left the old lady lying on that bed with her throat cut, and her clothes and the bed appeared soaked in blood."
