One Hour in Freedom by Jude Knight

When the machinations of a criminal compel Ellie Nomikos to seek out Dan Moriarty, she doesn’t know what to expect. Once they meant everything to one another. First, in London’s meanest streets and later in Spain facing Napoleon’s army, where betrayal and lies tore them apart.
With the mysterious King Nemesis circling for the kill, they must learn to trust one another again. Together, can they discover his identity and bring him to justice before he finds and kills the person most precious to them in the world?
The stakes could not be higher. Their love. Their lives. Their daughter.
