“So swift, silent and furtive were his movements like those of a trained bloodhound picking out a scent, that I could not but think what a terrible criminal he would have made had he turned his energy and sagacity against the law instead of exerting them in its defense.”

“I said that he was my superior in observation and deduction. If the art of the detective began and ended in reasoning from an armchair, my brother would be the greatest criminal agent that ever lived. But he has no ambition and no energy. He will not even go out of his way to verify his own solutions, and would rather be considered wrong than take the trouble to prove himself right.”

“The swing of his nature took him from extreme languor to devouring energy; and as I knew well, he was never so truly formidable as when, for days on end, he had been lounging in his armchair amid his improvisations and his black-letter editions. Then it was that the lust of the chase would suddenly come upon him, and that his brilliant reasoning power would rise to the level of intuition, until those who were unacquainted with his methods would look askance at him as on a man whose knowledge was not that of other mortals. When I saw him that afternoon so enwrapped in the music of St. James's Hall I felt that an evil time might be coming upon those whom he had set himself to hunt down.”

“One night--it was on the twentieth of March, 1888--I was returning from a journey to a patient(for I had now returned to civil practice), when my way led me through Baker Street. As I passed the well-remembered door...I was seized with a keen desire to see Holmes again, and to know how he was employing his extraordinary powers. His rooms were brilliantly lit, and, even as I looked up, I saw his tall, spare figure pass twice in a dark silhouette against the blind. He was pacing the room swiftly, eagerly, with his head sunk upon his chest and his hands clasped behind him. To me, who knew his every mood and habit, his attitude and manner told their own story. He was at work again. He had risen out of his drug-created dreams and was hot upon the scent of some new problems.”

“It was surely well for man that he came late in the order of creation. There were powers abroad in earlier days which no courage and no mechanism of his could have met. What could his sling, his throwing-stick, or his arrow avail him against such forces as have been loose tonight? Even with a modern rifle it would be all odds on the monster.”

“He had never said as much before, and I must admit that his words gave me keen pleasure, for I had often been piqued by his indifference to my admiration and to the attempts which I had made to give publicity to his methods. I was proud, too, to think that I had so far mastered his system as to apply it in a way which earned his approval.”

“I was not surprised. Indeed, my only wonder was that he had not already been mixed up in this extraordinary case, which was the one topic of conversation through the length and breadth of England. For a whole day my companion had rambled about the room with his chin upon his chest and his brows knitted, charging and recharging his pipe with the strongest black tobacco, and absolutely deaf to any of my questions or remarks. Fresh editions of every paper had been sent up by our news agent, only to be glanced over and tossed down into a corner. Yet, silent as he was, I knew perfectly well what it was over which he was brooding. There was but one problem before the public which could challenge his powers of analysis, and that was the singular disappearance of the favorite for the Wessex Cup, and the tragic murder of its trainer. When, therefore, he suddenly announced his intention of setting out for the scene of the drama it was only what I had both expected and hoped for.”
