Ok, here’s my turn at guessing what Moffat & Co. meant by “Rat. Wedding. Bow.”
So far as “Rat” goes:
I’m pretty set on it being the “Boscombe Valley Mystery.”
Take a [SPOILERY!!!!!!!] look at this excerpt from the text:
“What of the rat, then?”
Sherlock Holmes took a folded paper from his pocket and flattened it out on the table. “This is a map of the Colony of Victoria,” he said. “I wired to Bristol for it last night.” He put his hand over part of the map. “What do you read?”
“ARAT,” I read.
“And now?” He raised his hand.
“Quite so. That was the word the man uttered, and of which his son only caught the last two syllables. He was trying to utter the name of his murderer. So and so, of Ballarat.”
I think this sort of word-play is just up the Moftiss alley!
Why else might it have made their agenda for series 3, you ask?
Well, Lestrade features in it, which- given how popular the character and Rupert are- isn’t a bad thing for the show to try and capitalize on.
Plus, Watson is married in it, so we’re moving the stories forward. I don’t think they can really avoid “married” Watson for much longer. *Although, if they decided it was unrealistic for 2013, and just want to have John be in a monogamous relationship with someone else that he’ll eventually break up with…dude, I am DOWN for that interpretation of modernizing Victorian marriage.*
Next post- “Wedding!” Stay tuned.
