That the Hashishin had some means of communicating with me at the Astoria was evident from the contents of the note which I had received, and as I walked in the direction of the hotel my mind was filled with all sorts of misgivings. I was playing with fire! Had I done rightly or should I have acted otherwise? I sighed wearily. The dark future would resolve all my doubts.

When I reached the Astoria, Bristol had not arrived. I lighted a cigarette and sat down in the lounge to await his coming. Presently a boy approached, handing me a message which had been taken down from the telephone by the clerk. It was as follows—

Tell Mr. Cavanagh, who is waiting in the hotel, to take what I am expecting to his chambers, and say that I will join him there in twenty minutes.
INSPECTOR BRISTOL.

Again I doubted the wisdom of Bristol’s plan. Had I not fled to the Astoria to escape from the dangerous solitude of my rooms? That he was laying some trap for the Hashishin was sufficiently evident, and whilst I could not justly suspect him of making a pawn of me I was quite unable to find any other explanation of this latest move.

I was torn between conflicting doubts. I glanced at my watch. Yes! There was just time for me to revisit the bank ere joining Bristol at my chambers! I hesitated. After all, in what possible way could it jeopardize his plans for me merely to pretend to bring the keys?

“Hang it all!” I said, and jumped to my feet. “These maddening conjectures will turn my brain! I’ll let matters stand as they are, and risk the consequences!”

I hesitated no longer, but passed out from the hotel and once more directed my steps in the direction of Fleet Street.

As I passed in under the arch through which streamed many busy workers, I told myself that to dread entering my own chambers at high noon was utterly childish. Yet I did dread doing so! And as I mounted the stair and came to the landing, which was always more or less dark, I paused for quite a long time before putting the key in the lock.

The affair of the accursed slipper was playing havoc with my nerves, and I laughed dryly to note that my hand was not quite steady as I turned the key, opened my door, and slipped into the dim hallway.

As I closed it behind me, something, probably a slight noise, but possibly something more subtle—an instinct—made me turn rapidly.
