One Night With a Spy by Celeste Bradley

She is a mystery…
Lady Julia Barrowby is so much more than the lovely ornament to an old lord’s last years. When her husband/mentor passes away, Julia will ascend to the seat of the Fox of the Royal Four — if the other Three will accept a woman in their ranks! She’d love to prove herself to them, but her parlor is infested with suitors merely days after the funeral. Annoying, of course, except for the way one handsome man’s eyes follow her so sharply, as if he knows everything about her! Happily, she is certain that her secrets are safe.

He will do anything to uncover…
Lord Marcus Ramsay is ready to take his seat in the Royal Four and will allow no conniving gold-digger, even one so appealing, to steal his chair! When he discovers the secret, sensual diary of a lonely younger wife, he knows precisely how to pierce that lovely, cultured facade and discover the devious female beneath it! He will sweep her away with her own fantasies. But how to prevent being swept away himself?
