John Haldane, Earl of Strathairn, is on an urgent mission to find the killer of his fellow spy. Has the treasonous Frenchman, Count Forney, returned to England to wreak havoc? Or has someone new landed on English shores to stir up rebellion in the Midlands? After visiting the young widow of one of his agents, Strathairn strengthens his resolve never to wed. And most certainly not to Lady Sibella Winborne, with her romantic ideas of love and marriage. Unable to give Sibella up entirely, he has kept her close as a friend. And then weak fool that he is he kissed her.

Lady Sibella Winborne has refused several offers of marriage since her first Season years ago - when she first set eyes on the handsome Earl of Strathairn. Sibella's many siblings always rush to her aid to discourage an ardent suitor, but not this time. Her elder brother, Chaloner, Marquess of Brandreth, is insisting she marry. Sibella yearns to set up her own household. She is known to be the sensible member of the family. But she doesn't feel at all sensible about Lord Strathairn. If only she could forget that kiss.
