onsible, but I found myself
thinking of Poe's weird poem, "The Raven"; and like the character
therein I found myself hesitating.

I stole quietly into the passage. It was in darkness. How odd it
is that in moments of doubt instinctively one shuns the dark and
seeks the light. I pressed the switch lighting the hall lamp, and
stood looking at the closed door.

Why should this late visitor have rapped in so uncanny a fashion
in preference to ringing the bell?

I stepped back to my table and slipped a revolver into my pocket.

The muffled rapping was repeated. As I stood in the study doorway
I saw the flap of the letter-box slowly raised!

Instantly I extinguished both lights. You may brand me as
childishly timid, but incidents were fresh in my memory which
justified all my fears.

A faintly luminous slit in the door showed me that the flap was now
fully raised. It was the dim light on the stairway shining through.
Then quite silently the flap was lowered. Came the soft rapping
again.

"Who's there?" I cried.

Thereupon the flap became fully lifted, but from where I crouched
beneath it I was unable to see who or what was looking in; yet I
hesitated no longer. I suddenly raised myself and thrust the
revolver barrel through the opening!

"Who are you?" I cried. "Answer or I fire!"--and along the barrel
I peered out on to the landing.

Still no one answered. But something impalpable--a powder--a
vapour--to this hour I do not know what--enveloped me with its
nauseating fumes; was puffed fully into my face! My eyes, my
mouth, my nostrils became choked up, it seemed, with a deadly
stifling perfume.

Wildly, feeling that everything about me was slipping away, that I
was sinking into a void, for ought I knew that of dissolution, I
pulled the trigger once, twice, thrice...

"My God!"--the words choked in my throat and I reele
