Anastasia Mills (BBCSherlock Fanfic)

Anastatia Mills, a teenage girl who turns up on John Watsons doorstep with a bundle of evidence showing Sherlock Holmes innocence and proving he isnt a fraud at all, only weeks after his 'death'

Then she disapears, no one can fins her, its like she never exsisted at all.

Searches find nothing, no records of her ever exsisting, John begins to wonder if he imagined her to get over Sherlocks death, until she turned up again at his flat with news he never deemed possible.
