While You Were Spying - Regency Spies

Francesca Dashing would like to forget that Ethan Caxton, the Marquess of Winterbourne, exists. He humiliated her in front of all of London Society-and he doesn't even remember it! But when Ethan shows up in her sleepy Hampshire town, he's hard to overlook, and his presence stirs up long-buried feelings. Francesca tries to keep her distance...until her life is threatened and the mysterious and handsome marquess comes to her rescue, in more ways than she ever thought possible. Winterbourne has traveled to Hampshire on orders from the Foreign Office-he's investigating an arms smuggling ring and is determined to find its leader.
Miss Dashing stumbles into his way-literally-and derails both Ethan's assignment and his ordered country life. Ethan knows he needs to ignore the distraction, but when Francesca is the victim of a vicious attack, he's compelled to put aside his mission to protect her. Guarding the viscount's daughter is work, nothing more, and Ethan has no plans to let down his guard...until Francesca's chocolate-brown eyes and endless compassion melt the ice in his heart and lay siege to his defenses.
