Everyone hides secrets. Some provoke murder.
Olivia Denis discovers her father kneeling over the body of a man...a man who supposedly drowned in the Channel years before. Olivia wants to ring for help, her father wants to hide the body, but a mysterious phone call brings Scotland Yard to the murder scene.
Olivia can't stand by and let her maddening, disapproving father hang. To prove his innocence - and learn his secrets - she must work with a master spy. The search for clues takes Olivia to the continent and the Kent countryside, Hastings, and London, pushing her deeper into the world of danger and deception.
As war between Germany and Britain stalks closer, the hunt for a Nazi collaborator intensifies. With a mounting death toll, Olivia knows she must unmask the killer or be the next to die.
