Pheme’s Regret by Sue London

Can the darkest of betrayals ever be forgiven?
Miriam is known as Lady Spencer among the ton. A charming young widow with a string of admirers. In the London papers she is only known by the initials L.D., the signature given to all the best, and worst, gossip from Town. But she has been harboring her own secrets and will need the Haberdashers to accompany her on a trip to France to retrieve her illegitimate daughter.
Nicolas Baudin has everything in his life precisely as he likes it. Some might find his persnickety ways annoying, but when you’ve had your entire life upended by lies and speculation you prefer routine. That is part of why he enjoys practicing the law. Until a woman from England, his former home, comes to him with an unusual case, and everything he has been trying to forget comes crashing back.
