girl?"

"My dear Holmes," said I, "this is too much. You would certainly have been
burned had you lived a few centuries ago. It is true that I had a country
walk on Thursday and came home in a dreadful mess; but as I have changed
my clothes, I can't imagine how you deduce it. As to Mary Jane, she is
incorrigible, and my wife has given her notice; but there again I fail to
see how you work it out."

He chuckled to himself and rubbed his long nervous hands together.

"It is simplicity itself," said he, "my eyes tell me that on the inside of
your left shoe, just where the firelight strikes it, the leather is scored
by six almost parallel cuts. Obviously they have been caused by some one
who has very carelessly scraped round the edges of the sole in order to
remove crusted mud from it. Hence, you see, my double deduction that you
had been out in vile weather, and that you had a particularly malignant
boot-slicking specimen of the London slavey. As to your practice, if a
gentleman walks into my rooms, smelling of iodoform, with a black mark of
nitrate of silver upon his right forefinger, and a bulge on the side of
his top hat to show where he has secreted his stethoscope, I must be dull
indeed if I do not pronounce him to be an active member of the medical
profession."

I could not help laughing at the ease with which he, explained his process
of deduction. "When I hear you give your reasons," I remarked, "the thing
always appears to me so ridiculously simple that I could easily do it
myself, though at each successive instance of your reasoning I am baffled,
until you explain your process. And yet, I believe that my eyes are as
good as yours."
