Meanwhile, the Featherton sisters decide to hone their matchmaking skills by passing Jenny off to Society as a family friend. In no time, Jenny catches the eye of Callum Campbell, a handsome Scottish Marquis, and begins living the life of her dreams by day, while churning out gallipots of cream by night. Soon, her double life begins to catch up with her and what started out as a lark turns serious as Jenny falls for the dashing Callum. But will his feelings for her change when he discovers his Lady is actually a maid?
