Chris Lowndes built a comfortable career composing scores for films in Hollywood. But after 25 years abroad, and still quietly reeling from the death of his beloved wife, he decides to return to the Yorkshire dales of his youth. To ease the move, he buys Kilnsgate House, a rambling old mansion deep in the country.

Although Chris finds Kilnsgate charming, something about the house disturbs him, a vague sensation that the long-empty rooms have been waiting for him --- feelings made ever stronger when he learns that the house was the scene of a murder more than 50 years before. The former owner, a prominent doctor named Ernest Arthur Fox, was supposedly poisoned by his beautiful and much younger wife, Grace. Arrested and brought to trial, Grace was found guilty and hanged for the crime.

His curiosity piqued, Chris talks to the locals and searches through archives for information about the case. But the more he discovers, the more convinced he becomes that Grace may have been innocent. Ignoring warnings to leave it alone, he sets out to discover what really happened over half a century ago --- a quest that takes him deep into the past and into a web of secrets that lie all too close to the present.
