A Question of Numbers (A Lady Arianna Regency Mystery #5)
Andrea Penrose, Mary Sarah

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.
A friend, thought to have been killed in Elba, may in fact be alive and a French prisoner—putting his young daughter in danger of been kidnapped from her convent school and used to force her father into revealing critical military secrets. The mission is made even more complicated by yet another threat to Britain’s shaky military alliance . . . and the presence of an enigmatic Spanish beauty whose history with Saybrook is fraught with unsettling questions.
Love, friendship, loyalty. Trust will be tested as Arianna and Saybrook race against time to help defeat 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 . . .
