"I should imagine not," he said. "And yet, you see, I am here.
Coals of fire, Holmes--coals of fire!"

"It is very good of you--very noble of you. I appreciate your
special knowledge."

Our visitor sniggered.

"You do. You are, fortunately, the only man in London who does.
Do you know what is the matter with you?"

"The same," said Holmes.

"Ah! You recognize the symptoms?"

"Only too well."

"Well, I shouldn't be surprised, Holmes. I shouldn't be
surprised if it WERE the same. A bad lookout for you if it is.
Poor Victor was a dead man on the fourth day--a strong, hearty
young fellow. It was certainly, as you said, very surprising
that he should have contracted and out-of-the-way Asiatic disease
in the heart of London--a disease, too, of which I had made such
a very special study. Singular coincidence, Holmes. Very smart
of you to notice it, but rather uncharitable to suggest that it
was cause and effect."

"I knew that you did it."
