not quite grasped the significance of this sentence.«
    »No, I confess that I see no connection.«
    »And yet, my dear Watson, there is so very close a connection that the one
is extracted out of the other. You, your, your, life, reason, value, keep away,
from the. Don't you see now whence these words have been taken?«
    »By thunder, you're right! Well, if that isn't smart!« cried Sir Henry.
    »If any possible doubt remained it is settled by the fact that keep away and
from the are cut out in one piece.«
    »Well, now - so it is!«
    »Really, Mr. Holmes, this exceeds anything which I could have imagined,«
said Dr. Mortimer, gazing at my friend in amazement. »I could understand anyone

Western Morning News. But a Times leader is entirely distinctive, and these
words could have been taken from nothing else. As it was done yesterday the
strong probability was that we should find the words in yesterday's issue.«
    »So far as I can follow you, then, Mr. Holmes,« said Sir Henry Baskerville,
»someone cut out this message with a scissors -«
    »Nail-scissors,« said Holmes. »You can see that it was a very short-bladed

    »That is so. Someone,
