IT was the night following that of the double tragedy at Rowan House. Nayland Smith,
with Inspector Weymouth, was engaged in some mysterious inquiry at the docks, and I
had remained at home to resume my strange chronicle. And--why should I not confess
it?--my memories had frightened me.
I was arranging my notes respecting the case of Sir Lionel Barton. They were hopelessly
incomplete. For instance, I had jotted down the following queries:--(1) Did any true
parallel exist between the death of M. Page le Roi and the death of Kwee, the Chinaman,
and of Strozza? (2) What had become of the mummy of Mekara? (3) How had the
murderer escaped from a locked room? (4) What was the purpose of the rubber stopper?
(5) Why was Kwee hiding in the conservatory? (6) Was the green mist a mere subjective
hallucination--a figment of Croxted's imagination-- or had he actually seen it?
Until these questions were satisfactorily answered, further progress was impossible.
Nayland Smith frankly admitted that he was out of his depth. "It looks, on the face of it,
more like a case for the Psychical Research people than for a plain Civil Servant, lately of
Mandalay," he had said only that morning.
"Sir Lionel Barton really believes that supernatural agencies were brought into operation
by the opening of the high priest's coffin. For my part, even if I believed the same, I
should still maintain that Dr. Fu-Manchu controlled those manifestations. But reason it
out for yourself and see if we arrive at any common center. Don't work so much upon the
datum of the green mist, but keep to the FACTS which are established."
I commenced to knock out my pipe in the ash-tray; then paused, pipe in hand. The house
was quite still, for my landlady and all the small household were out.
Above the noise of the passing tramcar I thought I had heard the hall door open. In the
ensuing silence I sat and listened.
Not a sound. Stay! I slipped my hand into the table drawer, took out my revolver, and
stood up.
There WAS a sound. Someone or something was creeping upstairs in the dark!
Familiar with the ghastly media employed by the Chinaman, I was seized with an
impulse to leap to the door, shut and lock it. But the rustling sound proceeded, now, from
immediately outside my partially opened door. I had not the time to close it; knowing
somewhat of the horrors at the command of Fu-Manchu, I had not the courage to open it.
My heart leaping wildly, and my eyes upon that bar of darkness with its gruesome
potentialities, I waited--waited for whatever was to come. Perhaps twelve seconds passed
in silence.
