Her Husband’s Lover by Julia Crouch
Louisa lost her husband and children due to a car accident. But her late husband’s mistress Sophie wages a bitter and divisive war against Louisa. She wants the money, home and life she sees as her due. This is a dark excellent tale of non-negotiable attitudes, ill-disguised madness, differing perceived authenticity and a startling ending. This is a creepy twisty tale that I highly recommend.
