Not exactly a hero

This line is from the third episode from the BBC “Sherlock”, after a discussion that goes like this:

JW “There are lives at stake, Sherlock, actual human lives! Just so I know- do you care about that at all?”
SH “Will caring about them help save them?”
JW “No”
SH “Then I’ll continue not to make that mistake.”
JW "And you find that easy, do you?"
SH "Yes, very. Is that news to you?”
JW "No...No."

He’s all brains, and that’s probably the biggest part of his charm. ~

Sherlock Holmes and Doctor Watson, remember, belong to Sir Arthur Conan Doyle.
