Female Own Character X Sherlock RP? (Main situation ideas)

[Kassia Nightbloom]

I am a huge fan of the BBC show 'Sherlock'... That's why I always thinking about a OCx Sherlock roleplay. And why wouldn't this role play be romantic and erotic ...? ;)
I mean that I think that Sherlock is an alluring person, indeed he could be a sensual and sexual man actually.
So, I would like to find someone who would play the role of the detective...
Important note: better if you know the show. Sorry! But, I don't expect that you can be so brilliant like Sherlock. I am not force that "deduction-thing" for example... I know that it would be really hard.

Some possible roles for my OC:
1, The target of a killer (who needs protection)
2, A previous/ex client of Mr. Holmes
3, A young woman who will work with Sherlock in disguise (They have to pretend  that they are a couple and it turns out that they really attracted to each others...)
4, She is one of Mycroft Holmes' "people" who saves the detectives life (and she starts a relationship with him)
- Final point is that I am open for your ideas too...
We can talk more about it in private message and we also can work more on the ideas...
