Sherlock Quotes

Somebody loves you! If I had to punch that face, I'd
avoid the nose and teeth too.

Irene Adler

Mrs. Hudson: It's a disgrace, sending your little brother into danger
like that! Family is all we have in the end, Mycroft Holmes!
Mycroft Holmes: Oh shut up, Mrs. Hudson!
Sherlock and John: [furious] Mycroft!
Mycroft Holmes: [long pause] Apologies.
Mrs. Hudson: Thank you.
Sherlock: Though, do indeed shut up.
