Like nothing so much as a cat, the gleaming body (the dwarf was but scantily clothed) streaked through the open window!

Certain death, I thought, must be his lot upon the stones of the court far below. I ran and looked down, shaking in every limb, my mind filled with a loathing terror unlike anything I had ever known.

Brilliant moonlight flooded the pavement beneath; for twenty yards to left and right every stone was visible.

The court was empty!

Human, homely London moved and wrought intimately about me; but there, at sight of the empty court below, a great loneliness swept down like a mantle—a clammy mantle of the fabric of dread. I stood remote from my fellows, in an evil world peopled with the creatures of Hassan of Aleppo.

Moved by some instinct, as that of a frightened child, I dropped to my knees and buried my face in trembling hands.

CHAPTER VI
THE RING OF THE PROPHET

“There is no doubt,” said Mr. Rawson, “that great personal danger attaches to any contact with this relic. It is the first time I have been concerned with anything of the kind.”

Mr. Bristol, of Scotland Yard, standing stiffly military by the window, looked across at the gray-haired solicitor. We were all silent for a few moments.

“My late client’s wishes,” continued Mr. Rawson, “are explicit. His last instructions, evidently written but a short time prior to his death, advise me that the holy slipper of the Prophet is contained in the locked safe at his house in Dulwich. He was clearly of opinion that you, Mr. Cavanagh, would incur risk—great risk—from your possession of the key. Since attempts have been made upon you, murderous attempts, the late Professor Deeping, my unfortunate client, evidently was not in error.”
