d now my door-bell was ringing--as intuitively I had anticipated.
So certain was I of the identity of my visitor that as I walked
along the passage I was endeavouring to make up my mind how I should
act, how I should receive her.

I opened the door; and there, wearing European garments but a green
turban ... stood Hassan of Aleppo!

When I say that amazement robbed me of the power to speak, to move,
almost to think, I doubt not you will credit me. Indeed, I felt
that modern London was crumbling about me and that I was become
involved in the fantastic mazes of one of those Oriental intrigues
such as figure in the Romance of Abu Zeyd, or with which most
European readers have been rendered familiar by the glowing pages
of "The Thousand and One Nights."

"Effendim," said my visitor, "do not hesitate to act as I direct!"

In his gloved hand he carried what appeared to be an ebony cane.
He raised and pointed it directly at me. I perceived that it was,
in fact, a hollow tube.

"Death is in my hand," he continued; "enter slowly and I will
follow you."

Still the sense of unreality held me thralled and my brain refused

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
