Fake TV Meme: Show 3 'The Vanishing Heiress'

Okay, for this I need to apologise all round: incredible typecasting, mean-ness to certain ex-Spooks, cuteness, flimsy ITV-ness (but, hey, why should the BBC be the only British channel to get a fake show? :lol:) and the mangling of the prompt. (I didn't write it down, and here I am, all ready to post the show and checked it and went: "oh.") For all this, I am completely to blame*, and not john_elliott who gave me the following prompt:

The time: The Regency. The place: England. The morning after her coming-out ball, the protagonist discovers that she can become invisible at will. (Okay, so I lost the 'morning after' and 'at will' bit, but... er... well, it's done now, I've worked it all out... Drat.)

*See end for notes (and excuses).

Edit I just added in a couple bits. I'll try not to do that too much.
