With my disengaged hand I picked up the weapon. It was an air pistol of a rather formidable kind, quite capable of killing a man at twenty yards. I put it in my pocket, and, releasing my grip on her wrist stepped back a couple of paces.

"Won't you sit down?" I said pleasantly.

My invitation had an unexpected result. With a low moan she put up her hands in front of her face, and then, before I could catch her, swayed forwards and sank slowly to the floor.

"This," I said to myself, "is the mischief."

However, I couldn't very well leave her lying there, so, stooping down and raising her in my arms, I carried her to the sofa.

So far, things had travelled with such cheerful rapidity that I had had no time for reflection. But at this point it suddenly struck me that it would be as well to lock the door, in case Milford, or any other member of the household, had heard the crash of the bullet. So, crossing the room, I turned the key in the lock, and then came back to where my unconventional visitor was lying.

My first impression of her in the mirror had scarcely done her justice. There is a distinct gap between prettiness and beauty, and the girl who lay on the sofa was as lovely as a Greek statue. Indeed, but for the slightly parted lips and the long dark eyelashes, she might really have been chiselled out of marble. Her face was quite white, and only the faintest stirring of her breast gave any impression of life.

My acquaintance with the world has been fairly varied, but this was a situation right out of my previous line. Indeed, the problem of how to act for the best when shut up alone at midnight with a young lady who has just attempted to assassinate you is one of sufficient delicacy to baffle the most experienced. I decided that the first step was to bring her back to consciousness.

Putting some brandy into a glass, I carefully lifted her up and poured a few drops between her tightly-shut teeth. The strong spirit had an almost immediate effect. A faint tinge of colour stole into her face, and with a deep sigh she opened her eyes.

When she saw that I was holding her, she shuddered violently, and shrank back against the arm of the couch. It was not exactly complimentary, but I decided to overlook it.
