Wonderful as always. Oh, poor Holmes. He's so thoughtful and caring about Watson - discreetly letting Watson think he's found the new bath for himself, rather then tell Watson about it outright and risk Watson thinking Holmes is interfering and pitying him. It's such a kind choice - and then it comes back to hurt him.

I really like the final scene when Holmes' preoccupation means he mishears Mrs. Hudson - attributing his own negative thoughts to her.
