heard him murmur again:

"So, so, Franz sent him here! Ach, der Franz!"

As soon as I had passed out of sight of the lighted hall I found myself
in complete darkness. On each landing a jet of gas, turned down low,
flung a dim and flickering light a few yards around. On the third floor
I was able to distinguish by the gas rays a small plaque fastened to the
wall inscribed with an arrow pointing to the right above the figures:
46-30.

I stopped to strike a match to light my candle. The whole hotel seemed
wrapped in silence, the only sound the rushing of water in the gutters
without. Then from the darkness of the narrow corridor that stretched
out in front of me, I heard the rattle of a key in a lock.

I advanced down the corridor, the pale glimmer of my candle showing me
as I passed a succession of yellow doors, each bearing a white porcelain
plate inscribed with a number in black. No. 46 was the first room on
the right counting from the landing: the even numbers were on the right,
the odd on the left: therefore I reckoned on finding my room the last on
the left at the end of the corridor.

The corridor presently took a sharp turn. As I came round the bend I
heard again the sound of a key and then the rattling of a door knob, but
the corridor bending again, I could not see the author of the noise
until I had turned the corner.

I ran right into a man fumbling at a door on the left-hand side of the
passage, the last door but one. A mirror at the end of the corridor
caught and threw back the reflection of my candle.

The man looked up as I approached. He was wearing a soft black felt hat
and a black overcoat and on his arm hung an umbrella streaming with
rain. His candlestick stood on the floor at his feet. It had apparently
just been extinguished, for my nostrils sniffed the odour of burning
tallow.

"You have a light?" the stranger said in German in a curiously
breathless voice. "I have just come upstairs and the wind blew out my
candle and I could not get the door open. Perhaps you could ..." He
broke off gasping and put his hand to his heart.

"Allow me," I said. The lock of the door was inverted and to open the
door you had to insert the key upside-down. I did so and the door
opened easily. As it swung back I noticed the number of the room was 33,
next door to mine.

"Can I be of any assistance to you? Are you unwell?" I said, at the same
time lifting my candle and scanning the stranger's features.

He wa
