My dear Watson,
You're looking quite peaked, old chum. I dare say, a trip North would do you good. Really, you should take our newest client and go dash about a possibly haunted moor where something is trying to kill the man. Be sure to write, will you?
Kisses,
Sherlock
P.S.: By the way, I am better than you at everything. However, it's a hoot to keep you around because your forehead, when polished to a nice shine, reflects the glow of my awesome. Ta!
