Cleo knows she should be happy for her brother Mark. He's managed to find someone new after the sudden death of his first wife - but something about Evie just doesn't feel right...

When Evie starts having accidents at home, her friends grow concerned. Could Mark be causing her injuries? Called out to their cliff-top house one night, Sergeant Stephanie King finds two bodies entangled on blood-drenched sheets.

Where does murder begin? When the knife is raised to strike, or before, at the first thought of violence? As the accused stands trial, the jury is forced to consider - is there ever a proper defence for murder?
