n the river. Was this a
signal or a precaution? I glanced towards my two friends playing cards,
took another note of their broad shoulders and brawny arms, and prepared
to follow my host, who now stood bowing at the other end of the room,
before a covered staircase which was manifestly the sole means of
reaching the floor above.

"The staircase was quite a feature in the room. It ran from back to
front, and was boarded all the way up to the ceiling. On these boards
hung a few useless bits of chain, wire and knotted ends of tarred ropes,
which swung to and fro as the sharp November blast struck the building,
giving out a weird and strangely muffled sound. Why did this sound, so
easily to be accounted for, ring in my ears like a note of warning? I
understand now, but I did not then, full of expectation as I was for
developments out of the ordinary.

"Crossing the room, I entered upon the staircase, in the wake of my
companion. Though the two men at cards did not look up as I passed them,
I noticed that they were alert and ready for any signal I might choose
to give them. But I was not ready to give one yet. I must see danger
before I summoned help, and there was no token of danger yet.

"When we were about half-way up the stairs the faint light which had
illuminated us from below suddenly vanished, and we found ourselves in

exclaiming, 'Damn that fellow! What does he mean by shutting the door
before we're half-way up!' struck a match and lit a gas jet in the room
above, which poured a flood of light upon the staircase. Drawing my hand
from the pocket in which I had put my revolver, I hastened after him
into the small landing at the top of the stairs. An open door was before
me, in which he stood bowing, with the half-burnt match in his hand.
'This is the place, sir,' he announced, motioning me in.

"I entered and he remained by the door, while I passed quickly about the
room, which was bare of every article of furniture save a solitary table
and chair. There was not even a window in it, with the exception of one
small light situated so high up in the corner made by the jutting-up
staircase that I wondered at its use, and was only relieved of e
