"Why should you go further in it? What have you to gain from it?"
"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. When dusk comes we should find ourselves one stage advanced in our investigation."
================
1. art...: Sherlock Holmes wants to finish the case for fun, regardless of money.
2. series of lesson...:
-The case has the greatest fun at the last moment.
-To the greatest detective, he finds fun when he solves it at last.
-The case teaches people the greatest things(??) in life when a person is at the last moment of his life=death.
Do you agree?
