When CSI investigator Claire Watson meets John Rock on holiday, the attraction is instant—but so is the feeling that they've met before. Now uneasy memories from a decade earlier are beginning to surface for Claire: memories of a body found at the bottom of a cliff in Northern Ireland, a possible suicide or, perhaps, a murder. Now, ten years later in the South of France, she has once again encountered the dead woman's husband, the man Claire and her colleagues had believed was the killer, though they could never pin the crime on him.

But did John's wife really die by his hands? And if he is a cold-blooded murderer, why is Claire so violently attracted to him?
