Still the sense of unreality held me thralled and my brain refused me service. Like an hypnotic subject I walked back to my study, followed by my terrible visitor, who reclosed the door behind him.
He sat facing me across my littered table with the mysterious tube held loosely in his grasp.
How infinitely more terrifying are perils unknown than those known and appreciated! Had a European armed with a pistol attempted a similar act of coercion, I cannot doubt that I should have put up some sort of fight; had he sat before me now as Hassan of Aleppo sat, with a comprehensible weapon thus laid upon his knees, I should have taken my chance, should have attacked him with the lamp, with a chair, with anything that came to my hand.
But before this awful, mysterious being who was turning my life into channels unsuspected, before that black tube with its unknown potentialities, I sat in a kind of passive panic which I cannot attempt to describe, which I had never experienced before and have never known since.
"There is one about to visit you," he said, "whom you know, whom I think you expect. For it is written that she shall come and such events cast a shadow before them. I, too, shall be present at your meeting!"
His eagle eyes opened widely; they burned with fanaticism.
"Already she is here!" he resumed suddenly, and bent as one listening. "She comes under the archway; she crossed the courtyard — and is upon the stair! Admit her, effendim; I shall be close behind you!"
The door-bell rang.
With the consciousness that the black tube was directed toward the back of my head, I went and opened the door. My mind was at work again, and busy with plans to terminate this impossible situation.
On the landing stood a girl wearing a simple white frock which fitted her graceful figure perfectly. A white straw hat, of the New York tourist type, with a long veil draped from the back suited her delicate beauty very well. The red mouth drooped a little at the corners, but the big violet eyes, like lamps of the soul, seemed afire with mystic light.
