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_ {17} 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?"
