A few minutes later, having seen Milford safely tucked up and left the nurse in attendance, I made my way back to the hall, where I fastened the front door and put out both the candles and the electric light.

My visitor had left traces of blood all across the carpet, and I found spots of the same article decorating both the staircase and the landing above. It was evident that his study of art had been as intimate as it had been brief.

Somewhat cheered by this discovery, I entered my room, and, turning up the light, shut the door. The place was in a cheerful state of confusion, for, in addition to fire-irons, broken glass, and fragments of picture-frame, the overturned table and its contents were scattered generously round the room.

I tidied up things as well as I could, and then examined with some interest the marks left by the two unavailing swipes which my opponent had dealt at me in the duel. What his weapon was I could not say for certain, but from the traces which it had left behind, it appeared to have been something in the nature of an axe. My pillow was practically cut in half, while the dent which he had made in the wall left me with a certain sense of thankfulness that my head had not been in the spot where it landed.

After removing such portions of Park Lane as still adhered to my bare feet, I got into bed, turning my mangled pillow over on its other side. I left the electric light full on, for sleeping in the dark had, somehow or other, ceased to appeal to me. Then, with the agreeable feeling of a day well spent, I curled myself up under the clothes, and in five minutes I was fast asleep.

A little brisk exercise in the small hours of the night must, I think, be an excellent thing for the health. At all events, I woke up next morning feeling splendidly fit, and came down to breakfast with an even better appetite than on the previous day. My constitution requires an occasional stimulant, and with the job which I had undertaken there appeared to be little chance of its being denied this luxury.

I regret to say that the pretty parlour-maid seemed less fortunate. I was too sleepy to pay much attention to her when I was called, but later on, when she brought me in my eggs and bacon, I noticed that she had dark shadows under her eyes, and a general air of having spent a bad night.

"I am afraid you didn't sleep very well," I said.

She shook her head. "Neither me nor Cook closed our eyes the whole night, sir," she replied reproachfully.

"Oh, I'm sorry for that," I said. "You must go to bed early this evening, to make up for it. Have you heard how Milford is this morning?"
