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-slitting 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.â
I could not help laughing at the ease with which he explained his process of deduction. âWhen I hear you give your reasons,â I remarked, âthe thing always appears to me to be 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.â
âQuite so,â he answered, lighting a cigarette, and throwing himself down into an armchair. âYou see, but you do not observe. The distinction is clear. For example, you have frequently seen the steps which lead up from the hall to this room.â
âFrequently.â
âHow often?â
âWell, some hundreds of times.â
âThen how many are there?â
âHow many! I donât know.â
âQuite so. You have not observed. And yet you have seen. That is just my point. Now, I know that there are seventeen steps, because I have both seen and observed. By the way, since you are interested in these little problems, and since you are good enough to chronicle one or two of my trifling experiences, you may be interested in this.â He threw over a sheet of thick, pink-tinted note-paper which had been lying open upon the table. âIt came by the last post,â said he. âRead it aloud.â
The note was undated, and without either signature or address.
âThere will call upon you tonight, at a quarter to eight oâclock,â it said, âa gentleman who desires to consult you upon a matter of the very deepest moment. Your recent services to one of the Royal Houses of Europe have shown that you are one who may safely be trusted with matters which are of an importance which can hardly be exaggerated. This account of you we have from all quarters received. Be in your chamber then at that hour, and do not take it amiss if your visitor wear a mask.â
âThis is indeed a mystery,â I remarked. âWhat do you imagine that it means?â
âI have no data yet. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. But the note itself. What do you deduce from it?â
I carefully examined the writing, and the paper upon which it was written.
âThe man who wrote it was presumably well-to-do,â I remarked, endeavouring to imitate my companionâs processes. âSuch paper could not be bought under half a crown 8 a packet. It is peculiarly strong and stiff.â
âPeculiar â that is the very word,â said Holmes. âIt is not an English paper at all. Hold it up to the light.â
I did so, and saw a large
E
with a small
g
, a
P
, and a large
G
with a small
t
woven into the texture of the paper.
âWhat do you make of that?â asked Holmes.
âThe name of the maker, no doubt; or his monogram, rather.â
âNot at all. The
G
with the small
t
stands for â
Gesellschaft
â, which is the German for âCompanyâ. It is a customary contraction like our âCo.â.
P
, of course, stands for â
Papier
â. Now for the
Eg
. Let us glance at our Continental Gazetteer.â 9 He took down a heavy brown volume from his shelves. âEglow, Eglonitz â here we are, Egria. It is in a German-speaking country 10 â in Bohemia, not far from Carlsbad. 11 âRemarkable as being the scene of the
