An Honorable Deception by Roseanna M. White

In the trying art of balancing investigations and love, a detective must determine his priorities when faced with dangerous circumstances that could threaten everything he holds dear.

As the leader of the Imposters, an elite private investigative firm, 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 something much more dangerous.
Lady Lavinia Hemming suspects her longtime friends hold more secrets than they’re willing to admit, and when she stumbles upon the truth that they’re the esteemed Imposters, she recruits herself into the firm. While she is happy for the distraction of an investigation, Lavinia’s own family secrets continue to haunt her. And the one thing bringing laughter back into her life–her friendship with Yates–lands her squarely on the disagreeable side of her best friend: his sister.

Tormented by a past she doesn’t dare 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 dark side of society, Alethia, Yates, and Lavinia learn anew that the gentry isn’t always noble . . . even as they fight to hold fast to their own honor.
