ing the reason."

"Just as you like."

"If you will do this I think the chances are that our little
problem will soon be solved. I have no doubt----"

He stopped suddenly and stared fixedly up over my head into the
air. The lamp beat upon his face, and so intent was it and so
still that it might have been that of a clear-cut classical
statue, a personification of alertness and expectation.

"What is it?" we both cried.

I could see as he looked down that he was repressing some
internal emotion. His features were still composed, but his eyes
shone with amused exultation.

"Excuse the admiration of a connoisseur," said he as he waved his
hand towards the line of portraits which covered the opposite
wall. "Watson won't allow that I know anything of art, but that
is mere jealousy, because our views upon the subject differ. Now,
these are a really very fine series of portraits."

"Well, I'm glad to hear you say so," said Sir Henry, glancing
with some surprise at my friend. "I don't pretend to know much
about these things, and I'd be a better judge of a horse or a
steer than of a picture. I didn't know that you found time for
such things."

"I know what is good when I see it, and I see it now. That's a
Kneller, I'll swear, that lady in the blue silk over yonder, and
the stout gentleman with the wig ought to be a Reynolds. They are
all family portraits, I presume?"

"Every one."

"Do you know the names?"

"Barrymore has been coaching me in them, and I think I can say my
lessons fairly well."

"Who is the gentleman with the telescope?"

"That is Rear-Admiral Baskerville, who served under Rodney in the
West Indies. The man with the blue coat and the roll of paper is
Sir William Baskerville, who was Chairman of Committees of the
House of Commons under Pitt."

"And this Cavalier opposite to me--the one with the black velvet
and the lace?"

"Ah, you have a right to know about him. That is the cause of all
the mischief, the wicked Hugo, who started the Hound of the
Baskervilles. We're not likely to forget him."

I gazed with interest and some surprise upon the portrait.

"Dear me!" said Holmes, "he seems a quiet, meek-mannered man
enough, but I dare say that there was a lurking devil in his
eyes. I had pictured him as a more robust and ruffianly person."

"There's no doubt about the authenticity, for the name and the
date, 1647, are on the back of the canvas."

Holmes said little more, but the picture of
