had there been anyone in charge of it. Where, then, could the driver be, unless he were inside the house? Again, it is absurd to suppose that any sane man would carry out a deliberate crime under the very eyes, as it were, of a third person, who was sure to betray him. Lastly, supposing one man wished to dog another through London, what better means could he adopt than to turn cabdriver. All these considerations led me to the irresistible conclusion that Jefferson Hope was to be found among the jarveys of the Metropolis.
"If he had been one there was no reason to believe that he had ceased to be. On the contrary, from his point of view, any sudden chance would be likely to draw attention to himself. He would, probably, for a time at least, continue to perform his duties. There was no reason to suppose that he was going under an assumed name. Why should he change his name in a country where no one knew his original one? I therefore organised my Street Arab detective corps, and sent them systematically to every cab proprietor in London until they ferreted out the man that I wanted. How well they succeeded, and how quickly I took advantage of it, are still fresh in your recollection. The murder of Stangerson was an incident which was entirely unexpected, but which could hardly in any case have been prevented. Through it, as you know, I came into possession of the pills, the existence of which I had already surmised. You see the whole thing is a chain of logical sequences without a break or flaw."
"It is wonderful!" I cried. "Your merits should be publicly recognised. You should publish an account of the case. If you won't, I will for you."
"You may do what you like, Doctor," he answered. "See here!" he continued, handing a paper over to me, "look at this!"
It was the Echo for the day, and the paragraph to which he pointed was devoted to the case in question.
"The public," it said, "have lost a sensational treat through the sudden death of the man Hope, who was suspected of the murder of Mr. Enoch Drebber and of Mr. Joseph Stangerson. The details of the case will probably be never known now, though we are informed upon good authority that the crime was the result of an old standing and romantic feud, in which love and Mormonism bore a part. It seems that both the victims belonged, in their younger days, to the Latter Day Saints, and Hope, the deceased prisoner, hails also from Salt Lake City. If the case has had no other effect, it, at least, brings out in the most striking manner the efficiency of our detective police force, and will serve as a lesson to all foreigners that they will do wisely to settle their feuds at home, and not to carry them on to British soil. It is an open secret that the credit of this smart capture belongs entirely to the well-known Scotland Yard officials, Messrs. Lestrade and Gregson. The man was apprehended, it appears, in the rooms of a certain Mr. Sherlock Holmes, who has himself, as an amateur, shown some talent in the detective line, and who, with such instructors, may hope in time to attain to some degree of their skill. It is expected that a testimonial of some sort will be presented to the two officers as a fitting recognition of their services."
"Didn't I tell you so when we started?" cried Sherlock Holmes with a laugh. "That's the result of all our Study in Scarlet: to get them a testimonial!"
"Never mind," I answered, "I have all the facts in my journal, and the public shall know them. In the meantime you must make yourself contented by the consciousness of success, like the Roman miser—
"Populus me sibilat, at mihi plaudo
Ipse domi simul ac nummos contemplar in arca."

The Science of Deduction
Sherlock Holmes took his bottle from the corner of the mantelpiece and his hypodermic syringe from its neat morocco case. With his long, white, nervous fingers he adjusted the delicate needle, and rolled back his left shirt- cuff. For some little time his eyes rested thoughtfully upon the sinewy forearm and wrist all dotted and scarred with innumerable puncture-marks. Finally he thrust the sharp point home, pressed down the tiny piston, and sank back into the velvet-lined arm-chair with a long sigh of satisfaction.
Three times a day for many months I had witnessed this performance, but custom had not reconciled my mind to it. On the contrary, from day to day I had become more irritable at the sight, and my conscience swelled nightly within me at the thought that I had lacked the courage to protest. Again and again I had registered a vow that I should deliver my soul upon the subject, but there was that in the cool, nonchalant air of my companion which made him the last man with whom one would care to take anything approaching to a liberty. His great powers, his masterly manner, and the experience which I had had of his many extraordinary qualities, all made me diffident and backward in crossing him.
Yet upon that afternoon, whether it was the Beaune which I had taken with my lunch, or the additional exasperation produced by the extreme deliberation of his manner, I suddenly felt that I could hold out no longer.
“Which is it to-day?”
