Jealous Ghost [EPUB ebook] 

There is something rather disquieting about Sallie Declan, a young American in London, and it is not just her obsession with Henry James’s The Turn of the Screw, the subject of her Ph D thesis. There is her decision, almost casually taken, to leave her studies for a temporary job as a nanny in a large country house. She seems to display astonishing naivety as she build a fantasy about her emotional future there. Surely she can see it is all delusion? But a progressively darker reality unfolds as we are led inexorably towards a terrible and shocking climax.
