before ever I saw the box at all."

This last statement appeared to me to be so startling, that I could
hardly believe that he was in his sober senses. There was the dead dog,
however, to prove that his conjecture had been correct. It seemed to me
that the mists in my own mind were gradually clearing away, and I began
to have a dim, vague perception of the truth.

"All this seems strange to you," continued Holmes, "because you failed
at the beginning of the inquiry to grasp the importance of the single
real clue which was presented to you. I had the good fortune to seize
upon that, and everything which has occurred since then has served to
confirm my original supposition, and, indeed, was the logical sequence
of it. Hence things which have perplexed you and made the case more
obscure, have served to enlighten me and to strengthen my conclusions.
It is a mistake to confound strangeness with mystery. The most
commonplace crime is often the most mysterious because it presents no
new or special features from which deductions may be drawn. This murder
would have been infinitely more difficult to unravel had the body of
the victim been simply found lying in the roadway without any of
those _outre_ and sensational accompaniments which have rendered
it remarkable. These strange details, far from making the case more
difficult, have really had the effect of making it less so."

Mr. Gregson, who had listened to this address with considerable
impatience, could contain himself no longer. "Look here, Mr. Sherlock
Holmes," he said, "we are all ready to acknowledge that you are a smart
man, and that you have your own methods of working. We want something
more than mere theory and preaching now, though. It is a case of taking
the man. I have made my case out, and it seems I was wrong. Young
Charpentier could not have been engaged in this second affair. Lestrade
went after his man, Stangerson, and it appears that he was wrong too.
You have thrown out hints here, and hints there, and seem to know more
than we do, but the time has come when we feel that we have a right to
ask you straight how much you do know of the business. Can you name the
man who did it?"

"I cannot help feeling that Gregson is right, sir," remarked Lestrade.
"We have both tried, and we have both failed. You have remarked more
than once since I have been in the room that you had all the evidence
which you require. Surely you will not withhold it any longer."
