An Honorable Deception - Roseanna M. White

As the leader of elite private investigative firm the Imposters, Lord Yates Fairfax has made an art of concealing his identity. But when his newest client, the beautiful Lady Alethia Barremore, is shot while leaving their meeting, he throws caution to the wind and rushes to her aid. Though Lady Alethia thought she was only looking for her missing former nanny, she has clearly stumbled upon dangerous secrets. \n \nLady Lavinia Hemming suspects there's more to her oldest friends than they're willing to admit, and when she stumbles upon the truth that they're the Imposters, she recruits herself into the firm. Happy as she is for the distraction of an investigation, Lavinia's own family secrets continue to haunt her. And the one thing to bring laughter back into her life--her friendship with Yates--lands her squarely on the bad side of her best friend, his sister. \n \nTormented by a past that she doesn't dare to voice aloud, Lady Alethia does what she can to help her handsome host, her new friends, and the investigators. But as clues lead them deeper into the darkest of society's secrets, Alethia, Yates, and Lavinia soon learn anew that the gentry isn't always noble . . . and truth isn't always honorable.
