what millions of Europeans and Americans term 'the Yellow Peril! Very
good. Such an empire needs must have----"

"An emperor!"

Nayland Smith stopped his restless pacing immediately in front of me.

"Why not an _empress_, Petrie!" he rapped.

His words were something of a verbal thunderbolt; I found myself at
loss for any suitable reply.

"You will perhaps remind me," he continued rapidly, "of the lowly place
held by women in the East. I can cite notable exceptions, ancient and
modern. In fact, a moment's consideration by a hypothetical body of
Eastern dynast-makers not of an emperor but of an empress. Finally,
there is a persistent tradition throughout the Far East that such a
woman will one day rule over the known peoples. I was assured some
years ago, by a very learned pundit, that a princess of incalculably
ancient lineage, residing in some secret monastery in Tartary or Tibet,
was to be the future empress of the world. I believe this tradition,
or the extensive group who seek to keep it alive and potent, to be
what is called the Si-Fan!"

I was past greater amazement; but--

"This lady can be no longer young, then?" I asked.

"On the contrary, Petrie, she remains always young and beautiful by
means of a continuous series of reincarnations; also she thus
conserves the collated wisdom of many ages. In short, she is the
archetype of Lamaism. The real secret of Lama celibacy is the existence

their personal charms, and rendered dumb in order that they may never
report what they see and hear."

"Smith!" I cried, "this is utterly incredible!"

"Her body slaves are not only mute, but blind; for it is death to look
upon her beauty unveiled."

I stood up impatiently.

"You are amusing yourself," I said.

Nayland Smith clapped his hands upon my shoulders, in his own
impulsive fashion, and looked earnestly into my eyes.

"Forgive me, old man," he said, "if I have related all these fantastic
particulars as though I gave them credence. Much of this is legendary,
I know, some of it mere superstition, but--I am serious now, Petrie--
_part of it is true_."

I stared at the square-cut, sun-tanned face; and no trace of a smile
lurked about that grim mouth. "Such a woman may actually exist, Petrie,
only in legend; but, nevertheless, she forms the head center of that
giant conspira
