So, I was watching Sherlock season two for the fifth time and decided that I ought to post something on my personal hero (even though he claims not to be one). There are a lot of conspiracies floating around for season four, and I am here to attempt to make sense of them. If you have not seen seasons two and/or three, now is the time to stop reading and pick one of my other posts to read instead. YOU HAVE BEEN WARNED: MAJOR SPOILERS!!!
Moving on…there are a few things I would like to point out. Moriarty promised Sherlock four riddles. Every time Sherlock solved them, IOU would appear somewhere on the set. The first time (with the Hansel and Gretel allegory), Sherlock goes to the window and finds that the windows of the office building opposite have been spray-painted with the letters IOU. Next, when Sherlock is sent the gingerbread and figures out that Moriarty wants him to run instead of go quietly with the police, you can see a graffito behind Sherlock and Watson that also says IOU (also in red letters–the red ties in with the apple, and the fact that Moriarty wants to ‘burn the heart out of’ Sherlock). On the rooftop, I haven’t found any indicator of an IOU symbol, but it’s basically in Moriarty’s conversation with Sherlock. I think that the fourth riddle may be the fact that both Sherlock and Moriarty seem to miraculously come back to life, but that’s a bit woolly.
Now, to get to the real conspiracy theory I’ve been waiting to write about. The third Holmes brother. Yes, if you’ve been doing you’re research, you’ve heard about this. I noticed it for the first time in the last episode of the third season, when Mycroft remarks that he’s never been known for outbursts of brotherly compassion (or something to that effect). “You know what happened to the last one,” he says. That definitely implies another sibling. Also, in episode one (also in season three– titled The Empty Hearse), Mycroft and Sherlock are playing operation and Mycroft says, “We both thought you were an idiot.” Both could have meant Mycroft and Sherlock, but Sherlock is known for his ego. It’s unlikely that he thought he was an idiot. So, the third Holmes brother.
I assumed, like everyone else, that this third brother was going to be one of the few things Sherlock directors Mark Gatiss and Steven Moffat did outside of the canon story. However, I was doing some Holmes research and came up with this: there actually was a third brother. He was only mentioned briefly in the series, created to run the Holmes estate. If Mycroft had been the oldest, he would have been in charge with that and therefore unable to do the job he does in the books. So, Sir Arthur Conan Doyle came up with Sherrinford, the oldest Holmes brother. Doyle originally used Sherrinford as Sherlock’s name, but later changed it. So, if the directors decide to add the oldest Mr. Holmes into the BBC series, it will actually be canon. Cheers to Gatiss and Moffat for being superfans of Sherlock Holmes!
I only wish their sibling was female. Sigh. Maybe that will be the non-canon twist.
