Side by side we leaned upon the parapet looking down into the dirty courtyard which was the theatre of this weird mystery; looking down upon the stage, sordidly Western, where a mystic Eastern tragedy had been enacted.

I could see the constable standing beside the crushed thing upon the stones.

"Now," said Bristol, with a sort of awe in his voice, "where did he fall from?"

And at his words, looking down at the spot where the dwarf lay, and noting that he could not possibly have fallen there from any of the buildings surrounding the courtyard, an eerie sensation crept over me; for I was convinced that the happening was susceptible of no natural explanation.

I had heard — who has not heard? — of the Indian rope trick, where a fakir throws a rope into the air which remains magically suspended whilst a boy climbs upward and upward until he disappears into space. I had never credited accounts of the performance; but now I began seriously to wonder if the arts of Hassan of Aleppo were not as great or greater than the arts of fakir. But the crowning mystery to my mind was that of the Hashishin's death. It would seem that as he had hung suspended in space he had been shot!

"You say that someone heard the sound of the shot?" I asked suddenly.

"Several people," replied Bristol; "but no one knows, or no one will say, from what direction it came. I shall go on with the inquiry, of course, and cross-examine every soul in Wyatt's Buildings. Meanwhile, I'm open to confess that I am beaten."

In the velvet sky countless points blazed tropically. The hum of the traffic in Waterloo Road reached us only in a muffled way. Sordidness lay beneath us, but up there under the heavens we seemed removed from it as any Babylonian astronomer communing with the stars.

When, some ten minutes later, I passed out into the noise of Waterloo Road, I left behind me an unsolved mystery and took with me a great dread; for I knew that the quest of the sacred slipper was not ended, I knew that another tragedy was added to its history — and I feared to surmise what the future might hold for all of us.
