High Tide - Livia Franchini

Summer, 1992. Peter, a promising young artist, vanishes off the coast of Tuscany. Ten days later, his body washes ashore, bloated and unrecognisable. For one sweltering summer, his death grips the public imagination, before fading into the haze of nineties lore.

Thirty years on, Peter's widow, Marie, has become infamous in her own right. A cult but reclusive horror writer, her novels are celebrated for their dark brilliance - but no one knows the woman behind the pen name, or the memories she's spent a lifetime suppressing.

When a retrospective of Peter's work is announced at a prestigious London gallery, an old friend resurfaces who seems determined to drag Marie from the shadows and unmask her. Drawn back to Italy, she feels the past begin to stir: the heat, the secrets, the girl she once was. What does she owe the dead - and how far will she go to protect the living?
