Description
With the threat of war looming over the Continent now that Napoleon has re-seized the throne of France, London is abuzz with intrigue as diplomats from the European powers gather to negotiate a military alliance against him. But Lady Arianna and her husband, the Earl of Saybrook, are intent on staying clear of the conflict, deciding it's a battle for nations and armies to fight . . .
Until things turn very personal. When a Prussian diplomat is murdered, two items found in his pocket force Arianna and Saybrook to once again become reluctant allies with the shadowy head of British security and undertake a rescue mission to Brussels, where lies and deceptions swirl within the ballrooms of the British expatriate community as the armies of Wellington and Napoleon prepare to clash.
Love, friendship, loyalty. Trust will be tested as Arianna and Saybrook race against time to unravel a secret code which may hold the key to defeating the advancing French army. And as Arianna finds herself matching wits with Napoleon, it will once again all come down to a matter of Luck . . .
