"Bookish, fiercely intelligent, and a keen observer, Mary has deliberately cultivated a mousey persona that allows her to remain overlooked and significantly underestimated by all. It's the perfect cover for a sleuth, a role she stumbles into when trying to assist a close friend during a house party hosted by her parents at their stately Scottish home, Drumlanrig Castle.
A Most Intriguing Lady is scheduled for release in March
"It is at this party where Lady Mary also meets Colonel Walter Trefusis, a distinguished and extremely handsome war veteran. Tortured by memories of combat, Walter, like Mary, lives a double life, with a desk job in Whitehall providing a front for his role in the British Intelligence Service.
"The two form an unlikely alliance to solve a series of audacious crimes - and indulge in a highly charged on-off romance."
