The Baroness Affair (The Scarlet Salon #3)
Jean Wilde

Caroline Delaval, Baroness Hastings, is desperate for a child. The title needs an heir, and if she can’t inspire lust in her marriage bed, then she’s determined to find someone who can. Her discreet inquiries lead her straight to Piers Benson. She quickly learns, however, that it isn’t just her husband Piers plans on seducing.
No stranger to threesomes, Piers finds himself unusually drawn to his newest patrons. But before he can fully explore this budding relationship, a sinister plot threatens to upheave all of their lives. As he works to unravel this scheme, Piers finds himself embarking on an unexpected journey of self-discovery and love.
