“To his eyes all seemed beautiful, but to me a tinge of melancholy lay upon the countryside, which bore so clearly the mark of the waning year, Yellow leaves carpeted the lanes and fluttered down upon us as we passed, The rattle of our wheels died away as we drove through drifts of rotting vegetation--sad gifts, as it seemed to me, for Nature to throw before the carriage of the returning heir of the Baskervilles.”

“Over the green squares of the fields and the low curves of a wood there rose in the distance a grey, melancholy hill, with a strange jagged summit, dim and vague in the distance like some fantastic landscape in a dream. Baskerville sat for a long time, his gaze fixed upon it, and I read upon his eager face how much it meant to him, this first sight of that strange spot where the men of his blood had held sway so long and left their mark so deep.”

“WATSON: Then you are yourself inclining to the supernatural explanation.     HOLMES: if Dr. Mortimer's surmise should be correct, and we are dealing with forces outside the ordinary laws of Nature, there is an end of our investigation. But we are bound to exhaust all other hypotheses before falling back upon this one.”

“What a lovely thing a rose is!"He walked past the couch to the open window and held up the drooping stalk of a moss-rose, looking down at the dainty blend of crimson and green. It was a new phase of his character to me, for I had never before seen him show any keen interest in natural objects. "There is nothing in which deduction is so necessary as religion," said he, leaning with his back against the shutters. "It can be built up as an exact science by the reasoner. Our highest assurance of the goodness of Providence seems to me to rest in the flowers. All other things, our powers, our desires, our food, are all really necessary for our existence in the first instance. But this rose is an extra. Its smell and its color are an embellishment of life, not a condition of it. It is only goodness which gives extras, and so I say again that we have much to hope from the flowers.”

“Miss Morstan and I stood together, and her hand was in mine. A wondrous subtle thing is love, for here were we two, who had never seen each other until that day, between whom no word or even look of affection had ever passed, and yet now in an hour of trouble our hands instinctively sought for each other. I have marveled at it since, but at the time it seemed the most natural thing that I would go out to her so, and, as she has often told me, there was in her also the instinct to turn to me for comfort and protection. So we stood hand in hand like two children, and there was peace in our hearts for all the dark things that surrounded us.”

“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 is my belief, Watson, founded upon my experience, that the lowest and vilest alleys in London do not present a more dreadful record of sin than does the smiling and beautiful countryside.”
