week in London, waiting some
excuse to get my hand on his collar. Mr. Gregson and I ran him to
ground in that big tenement house, and there's only one door, so he
can't slip us. There's three folk come out since he went in, but I'll
swear he wasn't one of them."
"Mr. Holmes talks of signals," said Gregson. "I expect, as usual, he
knows a good deal that we don't."
In a few clear words Holmes explained the situation as it had appeared
to us. The American struck his hands together with vexation.
"He's on to us!" he cried.
"Why do you think so?"
"Well, it figures out that way, does it not? Here he is, sending out
messages to an accomplice--there are several of his gang in London.
Then suddenly, just as by your own account he was telling them that
there was danger, he broke short off. What could it mean except that
from the window he had suddenly either caught sight of us in the

that he must act right away if he was to avoid it? What do you
suggest, Mr. Holmes?"
"That we go up at once and see for ourselves."
"But we have no warrant for his arrest."

bearing with which he would have ascended the official staircase of
Scotland Yard. The Pinkerton man had tried to push past him, but
Gregson had firmly elbowed him back. London dangers were the privilege
of the London force.
The door of the left-hand flat upon the third landing was standing
ajar. Gregson pushed it open. Within all was absolute silence and
darkness. I struck a match and lit the detective's lantern. As I did
so, and as the flicker steadied into a flame, we all gave a gasp of
surprise. On the deal boards of the carpetless floor there was
outlined a fresh track of blood. The red steps pointed towards us and
led away from an inner room, the door of which was closed. Gregson
flung it open and held his light full blaze in front of him, while we
all peered eagerly over his shoulders.
