A young woman wakes in a strange bed.

A sickly light filters through a metal grille.

Doctor Maynard Straker steps into the room, and speaks.

'Have no fear, Miss Ashton. I am entirely at your service.'

This, however, is not her name.

And she should not be here - in the Asylum.

She is Miss Georgina Ferrars, and she can prove it.

But when Dr Straker sends a telegram to her uncle in London, the reply is swift:

GEORGINA FERRARS HERE STOP
YOUR PATIENT MUST BE IMPOSTER STOP

Madness? Mistaken identity? Or are there more malevolent forces at work?
