He's back in her life, and his life is in her hands! Lady Marcia Calderbank has done her best to lose the lady wearing trousers, campaigning for women's suffrage...why, she's even taken on dangerous investigative missions for her brother's detective agency! At thirty-two, she's happily unmarried and completely concerned by the way Society has scorned her. But her latest mission will require her remembering everything her mother taught her about propriety. Because the Crown has demanded she prove that "Hawk" Hawthorne, the new Baron Tostinham, is guilty of murder. And Hawk—her brother's best friend—is demanding she save him, by proving to Society he's the gentleman she knows him to be. So what's it going to be? Her loyalty to her brother, her lover, and her heart...or her loyalty to the Crown? If she waits too long to decide, the choice will be taken from her. A fabulous start to a new super-spicy, laugh-out-loud series from the queen of HistRomCom, Caroline Lee!
