Well, even leaving aside the spelling of her surname (which I get is pronounced similarly if you have a non-rhotic accent), pretty much the whole point of Miss Havisham's character is that she's a 'Miss'!
My choice is Charlotte Mullen from Somerville and Ross's The Real Charlotte (late-Victorian masterpiece which should be better known outside of Ireland than it is) -- a brilliantly, comically awful, yet relatable, villain.
She is a clever, plain middle-aged spinster in late 19thc smalltown Ireland, who can't train for the profession her brains, guile and quickness would make her endlessly suited to because of her sex, while her repellent plainness, 'masculine' cleverness and lack of 'feminine charms' mean she has never had a chance on the marriage market. Well aware of her lack, she constructs herself as a sort of honorary man, and is very good at inserting herself in socially everywhere from the local Big House to the houses of the local poor. She dials her accent and manner up and down.
It all gets terribly interesting, and ugly, when a pretty young cousin who comes to stay with her attracts the attention of the man she has loved helplessly since her teens (even though he married someone else for money)...
She cheats, lies, spies, manipulates, and does absolutely appalling things, amounting to murder in one case, and almost in another, when her young cousin is in danger from some stampeding horses, and she contemplates 'accidentally' falling and failing to shut the gate that would save her from being trampled, and free up the (weak) man she loves to be manipulated into marrying her...
But everyone who has ever looked in the mirror and hated what they saw will 'get' the way she dresses with 'eccentric' simplicity because she knows it would make her laughed at if other women saw her dressing in a 'feminine' way, as if to try to attract men, and the pain of a man simply not ever seeing you as a woman.
I strongly recommend it!
