In the picturesque seaside town of St Ives, Detective Sergeant Sophie Keane is a pillar of the community. Between the occasional collar and lazy weekends spent on the beach, it seems a perfect life. But for Sophie, the golden sands and crystal waters hide a dark secret, one that's lain buried for twenty years. When a body turns up on the opening night of a glittering new art gallery on the seafront, the town is left shaken - especially Sophie, who recognises the killer's style but knows that what she fears just couldn't be possible. With a killer on the loose, everyone's a suspect - especially newcomer Gabriel Rowe, who seems to have settled in far too quickly for her liking. For Sophie, he's guilty until proven innocent.
