Lady Elizabeth arrives in Paris on a last-minute invitation, expecting embassy receptions and a reunion with her childhood friend, Clemmi Sterling, née Mayfield.
Jonathan Ashcroft's unexpected presence in the city, together with his secretive behaviour, pulls her into the streets after dark.
On Pont Neuf she watches a covert meeting erupt in gunfire, then sees Jonathan fall into the Seine.
The official account does not match what she witnessed, and Clemmi's husband, Oliver, turns aside every question she asks.
Loyalty to her oldest friend now collides with a trail of deception that reaches into British intelligence and Parisian political circles.
Elizabeth must expose the murderer before the next strike lands.
