It's quite exciting," said Sherlock Holmes, with a yawn.

I am the most incurably lazy devil that ever stood in shoe leather.

You're not hurt, Watson? For God's sake, say that you are not hurt!"
It was worth a wound -- it was worth many wounds -- to know the depth of loyalty and love which lay behind that cold mask. The clear, hard eyes were dimmed for a moment, and the firm lips were shaking. For the one and only time I caught a glimpse of a great heart as well as of a great brain. All my years of humble but single-minded service culminated in that moment of revelation.

I cannot live without brainwork. What else is there to live for? Stand at the window here. Was ever such a dreary, dismal, unprofitable world? See how the yellow fog swirls down the street and drifts across the duncoloured houses. What could be more hopelessly prosaic and material?

No man burdens his mind with small matters unless he has some very good reason for doing so.

To a great mind, nothing is little,' remarked Holmes, sententiously.
