Set against the backdrop of a prestigious private school, a foreboding forest and the quiet sprawl of Bristol, Gone, is a chilling mystery focusing on local Headmaster Michael Polly, who becomes the prime suspect in his wife Sarah's disappearance. An upstanding member of the community, Michael Polly is inscrutable and likes order and precision in his working life. Until, that is, he encounters super bright, gutsy Detective Annie Cassidy, and a compulsive game of cat and mouse begins as she chips away at his veneer in search of the truth.
