That moment was pungent with drama. In the intense hush of the next five seconds I could fancy that the world had slipped away from me and that I was become an unsubstantial thing of dreams. I was in no sense master of myself; the effect of the presence of this white-bearded fanatic was of a kind which I am entirely unable to describe. About Hassan of Aleppo was an aroma of evil, yet of majesty, which marked him strangely different from other men - from any other that I have ever known. In his venerable presence, remembering how he was Sheikh of the Assassins, and recalling his bloody history, I was always conscious of a weakness, physical and mental. He appalled me; and now, with my back to the door, I stood watching him and watching the ominous black tube which he held in his hand. It was a weapon unknown to Europe and therefore more fearful than the most up-to-date of death-dealing instruments.
Hassan of Aleppo pointed it toward me.
"The keys, effendim," he said; "hand me the keys!"
He advanced a step; his manner was imperious. The black tube was less than a foot removed from my face. That I had my revolver in my pocket could avail me nothing, for in my pocket it must remain, since I dared to make no move to reach it under cover of that unfamiliar, terrible weapon.
The black eyes of Hassan glared insanely into mine.
"You will have placed them in your pocketcase," he said. "Take it out; hand it to me!"
I obeyed, for what else could I do? Taking the case from my pocket, I placed it in his lean brown hand.
An expression of wild exultation crossed his features; the eagle eyes seemed to be burning into my brain. A puff of hot vapour struck me in the face - something which was expelled from the mysterious black tube. And with memories crowding to my mind of similar experiences at the hands of the Hashishin, I fell back, clutching at my throat, fighting for my life against the deadly, vaporous thing that like a palpable cloud surrounded me. I tried to cry out, but the words died upon my tongue. Hassan of Aleppo seemed to grow huge before my eyes like some ginn of Eastern lore. Then a curtain of darkness descended. I experienced a violent blow upon the forehead (I suppose I had pitched forward), and for the time resigned my part in the drama of the sacred slipper.
