Island of bones

Gabriel Crowther's brother was hanged for their father's murder in 1751. Thirty years later, his sister returns with her wayward son to their childhood home of Keswick. A body has been found on the little 'island of bones' in nearby Derwent Water, and the town is sick with rumours and suspicion. All eyes turn towards Crowther and his friend Harriet Westerman to cure them, but he finds that his own past will not stay buried.
