Holmes had been seated for some hours in silence with his long,
thin back curved over a chemical vessel in which he was brewing a
particularly malodorous product. His head was sunk upon his
breast, and he looked from my point of view like a strange, lank
bird, with dull grey plumage and a black top-knot.
“So, Watson,” said he, suddenly, “you do not propose to invest in
South African securities?”
I gave a start of astonishment. Accustomed as I was to Holmes’s
curious faculties, this sudden intrusion into my most intimate
thoughts was utterly inexplicable.
“How on earth do you know that?” I asked.
He wheeled round upon his stool, with a steaming test-tube in his
hand, and a gleam of amusement in his deep-set eyes.
“Now, Watson, confess yourself utterly taken aback,” said he.
“I am.”
“I ought to make you sign a paper to that effect.”
“Why?”
“Because in five minutes you will say that it is all so absurdly
simple.”
“I am sure that I shall say nothing of the kind.”
“You see, my dear Watson,”—he propped his test-tube in the rack,
and began to lecture with the air of a professor addressing his
class—“it is not really difficult to construct a series of
inferences, each dependent upon its predecessor and each simple
in itself. If, after doing so, one simply knocks out all the
central inferences and presents one’s audience with the
starting-point and the conclusion, one may produce a startling,
though possibly a meretricious, effect. Now, it was not really
difficult, by an inspection of the groove between your left
forefinger and thumb, to feel sure that you did _not_ propose to
invest your small capital in the gold fields.”
“I see no connection.”
“Very likely not; but I can quickly show you a close connection.
Here are the missing links of the very simple chain: 1. You had
chalk between your left finger and thumb when you returned from
the club last night. 2. You put chalk there when you play
billiards, to steady the cue. 3. You never play billiards except
with Thurston. 4. You told me, four weeks ago, that Thurston had
an option on some South African property which would expire in a
month, and which he desired you to share with him. 5. Your check
book is locked in my drawer, and you have not asked for the key.
6. You do not propose to invest your money in this manner.”
“How absurdly simple!” I cried.
“Quite so!” said he, a little nettled. “Every problem becomes
very childish when once it is explained to you. Here is an
unexplained one. See what you can make of that, friend Watson.”
He tossed a sheet of paper upon the table, and turned once more
to his chemical analysis.
I looked with amazement at the absurd hieroglyphics upon the
paper.
“Why, Holmes, it is a child’s drawing,” I cried.
“Oh, that’s your idea!”
“What else should it be?”
“That is what Mr. Hilton Cubitt, of Riding Thorpe Manor, Norfolk,
is very anxious to know. This little conundrum came by the first
post, and he was to follow by the next train. There’s a ring at
the bell, Watson. I should not be very much surprised if this
were he.”
A heavy step was heard upon the stairs, and an instant later
there entered a tall, ruddy, clean-shaven gentleman, whose clear
eyes and florid cheeks told of a life led far from the fogs of
Baker Street. He seemed to bring a whiff of his strong, fresh,
bracing, east-coast air with him as he entered. Having shaken
hands with each of us, he was about to sit down, when his eye
rested upon the paper with the curious markings, which I had just
examined and left upon the table.
“Well, Mr. Holmes, what do you make of these?” he cried. “They
told me that you were fond of queer mysteries, and I don’t think
you can find a queerer one than that. I sent the paper on ahead,
so that you might have time to study it before I came.”
“It is certainly rather a curious production,” said Holmes. “At
first sight it would appear to be some childish prank. It
consists of a number of absurd little figures dancing across the
paper upon which they are drawn. Why should you attribute any
importance to so grotesque an object?”
“I never should, Mr. Holmes. But my wife does. It is frightening
her to death. She says nothing, but I can see terror in her eyes.
That’s why I want to sift the matter to the bottom.”
Holmes held up the paper so that the sunlight shone full upon it.
It was a page torn from a notebook. The markings were done in
pencil, and ran in this way:
