Who, or what, is Esther Bligh?

At the end of the Second World War, Grace Marlowe moves to the far west of Wales, hoping for a fresh start. Instead, she finds herself trapped in a dark, forgotten house, surrounded by a bleak landscape and unwelcoming neighbours. Even her ‘voices’ – her spirit-world companions – appear to abandon her. Except for one…

Then anonymous letters begin to arrive, addressed to ‘Mrs. Esther Bligh’, dated more than twenty years before. They accuse Esther of the worst of crimes, committed in this same house – a place she had arrived in as a young bride, but had quickly come to detest.

Soon, Grace becomes increasingly lost in the nightmare vision of Esther’s past deeds, conjured by the words from the letters, together with the voice in her head.

And, like the voice, Esther’s presence in the house grows ever stronger.

A psychological exploration of a troubled mind, or a story of demonic possession in a haunted house? What ‘Esther Bligh’ is, is as ambiguous as the character herself.
