ing else?" Holmes asked.
"Nothing of any importance. The man's novel, with which he had read
himself to sleep was lying upon the bed, and his pipe was on a chair
beside him. There was a glass of water on the table, and on the
window-sill a small chip ointment box containing a couple of pills."
Sherlock Holmes sprang from his chair with an exclamation of delight.
"The last link," he cried, exultantly. "My case is complete."
The two detectives stared at him in amazement.
"I have now in my hands," my companion said, confidently, "all the
threads which have formed such a tangle. There are, of course, details
to be filled in, but I am as certain of all the main facts, from the
time that Drebber parted from Stangerson at the station, up to the
discovery of the body of the latter, as if I had seen them with my own
eyes. I will give you a proof of my knowledge. Could you lay your hand
upon those pills?"
"I have them," said Lestrade, producing a small white box; "I took them
and the purse and the telegram, intending to have them put in a place of

"Precisely so," answered Holmes. "Now would you mind going down and
fetching that poor little devil of a terrier which has been bad so long,
and which the landlady wanted you to put out of its pain yesterday."
I went downstairs and carried the dog upstair in my arms. It's laboured
breathing and glazing eye showed that it was not far from its end.
Indeed, its snow-white muzzle proclaimed that it had already exceeded
the usual term of canine existence. I placed it upon a cushion on the
rug.
"I will now cut one of these pills in two," said Holmes, and drawing his
penknife he suited the action to the word. "One half we return into the
box for future purposes. The other half I will place in this wine glass,
in which is a teaspoonful of water. You perceive that our friend, the
Doctor, is right, and that it readily dissolves."
"This may be very interesting," said Lestrade, in the injured tone of
one who suspects that he is
