Here’s another one for Dean Street December!
Because of the war, Susan Prioleau never meets her mother-in-law before she dies. Mrs. Prioleau seems to have kept an unhappy home, with children who left it as soon as they could, excepting Austin, her oldest son. She adored him but convinced him he is an invalid with a bad heart, which his doctor says is not true. He is immensely fat and makes his heart an excuse for doing nothing.
Susan hears stories about Mrs. Prioleau that don’t agree. She was adored by her servants of long ago, but she has written people cruel, vindictive letters. Both her daughters say she never gave them any attention, although the oldest, Nonnie, remembers a time when things were different. Her daughter Melissa disliked her, and she was estranged from her sister, Catherine, for years.
As Susan gets to know the family and helps Austin clear the house (although he won’t let her remove much), she begins to learn more about her mother-in-law’s life. Eventually, she learns about events that turned her from a selfish but warm-hearted girl to a spiteful old woman.
It’s a pity Monica Tindall only wrote one novel, because this is a good one. Although some of its secrets are easy to guess, the journey was absorbing.
What? Me Read? 
I’ve never heard of either the book or the author, but it sounds really good!
Yes, it’s one of the Furrowed Middlebrow books I’ve liked best.
Sounds intriguing!
