Murder in Westminster (Lady Worthing Mysteries 1)

The first in a vibrant, inclusive new historical mystery series by acclaimed author Vanessa Riley portrays the true diversity of the Regency-era, as a widow whose skin color and notorious family history have left her with few friends she can rely on - just as the local vicar names her the prime suspect in a murder case...
Discovering a body on her property presents Lady Abigail Worthing with more than one pressing problem. The victim is Juliet, the wife of her neighbor, Stapleton Henderson. Although Abigail has little connection with the lady in question, she expects to be under suspicion. Abigail's skin color and her mother's notorious past have earned her a certain reputation among the ton, and no amount of wealth or status will eclipse it.
Abigail can't divulge that she was attending a secret pro-abolition meeting at the time of the murder. To her surprise, Henderson offers her an alibi. Though he and Juliet were long estranged, and she had a string of lovers, he feels a certain loyalty to his late wife. Perhaps together, he and Abigail can learn the truth.
Abigail, whose marriage to Lord Worthing was not a love match, knows well how appearances can deceive. For all its surface elegance, London's high society can be treacherous. Yet who in their circle would have killed Juliet, and why? Taking the reins of her life in a way she never has before, Abby intends to find out--but in the process she will uncover more danger than she ever imagined...
