turning round at the door: "'Rache,' is the German
for 'revenge;' so don't lose your time looking for Miss Rachel."

CHAPTER IV. WHAT JOHN RANCE HAD TO TELL.

IT was one o'clock when we left No. 3, Lauriston Gardens. Sherlock
Holmes led me to the nearest telegraph office, whence he dispatched a
long telegram. He then hailed a cab, and ordered the driver to take us
to the address given us by Lestrade.

"There is nothing like first hand evidence," he remarked; "as a matter
of fact, my mind is entirely made up upon the case, but still we may as
well learn all that is to be learned."

"You amaze me, Holmes," said I. "Surely you are not as sure as you
pretend to be of all those particulars which you gave."

"There's no room for a mistake," he answered. "The very first thing
which I observed on arriving there was that a cab had made two ruts with
its wheels close to the curb. Now, up to last night, we have had no rain
for a week, so that those wheels which left such a deep impression must
have been there during the night. There were the marks of the horse's
hoofs, too, the outline of one of which was far more clearly cut than
that of the other three, showing that that was a new shoe. Since the cab
was there after the rain began, and was not there at any time during the
morning--I have Gregson's word for that--it follows that it must have
been there during the night, and, therefore, that it brought those two
individuals to the house."

"That seems simple enough," said I; "but how about the other man's
height?"

"Why, the height of a man, in nine cases out of ten, can be told from
the length of his stride. It is a simple calculation enough, though
there is no use my boring you with figures. I had this fellow's stride
both on the clay outside and on the dust within. Then I had a way of
checking my calculation. When a man writes on a wall, his instinct leads
him to write about the level of his own eyes. Now that writing was just
over six feet from the ground. It was child's play."

"And his age?" I asked.

"Well, if a man can stride four and a-half feet without the smallest
effort, he can't be quite in the sere and yellow. That was the breadth
of a puddle on the garden walk which he had evidently walked across.
Patent-leather boots had gone round, and Square-toes had hopped over.
There is no mystery about it at all. I am
