Sherlock Holmes - Sayings

“Why should you go further in it? What have you to gain from it?” (Watson)
“What, indeed? It is art for art’s sake, Watson. I suppose when you doctored you found yourself studying cases without thought of a fee?”
“For my education, Holmes.”
“Education never ends, Watson. It is a series of lessons with the greatest for the last. This is an instructive case. There is neither money nor credit in it, and yet one would wish to tidy it up.”
