When plunged into a world of spies, agents and espionage during the Peninsula wars, Honor, Lady Beaumont, flees for her life when the French capture her husband at Salamanca, and relies on his batman to arrange her safe passage back to England.

Viscount Charles Vidal is ordered by Robert Dumas, the First Lord of the Admiralty, to travel to Spain and escort the only woman he's ever loved, Lord Devlin Beaumont's widow back home before the French discover her whereabouts.

Their journey is fraught by danger, least of all knowing whether they are surrounded by friends or foe. Will they survive long enough to explore the possibility of a future together or will whispers of treason be enough to see Honor dispatched to Tyburn first?
