Lady Elizabeth Smallwood

As always....***SPOILER ALERT*** 

I don't trust Lady Elizabeth Smallwood any farther than I can throw her. "I haven't done any of the things you're accusing me of," she tells Mycroft when he interrogates her in "The Six Thatchers." I did not like her word choice when I watched it the first time, chalking it up to shoddy writing, but then she flirts with him in "The Lying Detective."

Here is my theory. Lady Smallwood has been a double agent for years, but when she is finally confronted, Mycroft accuses her of a betrayal she did not commit. She is then able to say with complete honesty that she is innocent. However, she now knows that Mycroft is not above suspecting her of committing treason, and she, therefore, needs to keep Mycroft on her good side. What better way for her to do that than by using her feminine wiles? Smallwood will not succeed in seducing Mycroft, but it will succeed in distracting him. This will, no doubt, confuse Mycroft, and he will focus on her flirtatious behavior rather than her work with either Moriarty or Euros.

Ms. Moriarty

By now, I have come to the conclusion that Jim Moriarty is dead. As Steven Moffat has said more than once, you cannot fake shooting yourself in the face. So, the question remains: Who plastered Jim Moriarty face all over Britain's televisions?

At the end of "The Great Game", the museum curator says, "No one sees [Moriarty's] face." Sherlock has seen Jim Moriarty's face, and the entire world saw his face during the trial. Why put himself out there? He does not get his hands dirty. This is a break from his pattern. But what if he did not actually break his pattern?

 I have previously discussed the canonical brother of Professor James Moriarty, Colonel James Moriarty. I am not the only person who has proposed a Moriarty twin theory, but I would like to explore a potential twist on that theory. 

When Moriarty plays with Sherlock in the great game, the first writing on the envelope containing the pink phone was written by a woman.

Changing a character's gender is nothing new to Sherlock. In the very first episode, John Watson's brother is switched to a woman. 

So, what if Colonel James Moriarty is being portrayed as a Ms. Moriarty?
