While I have not read this, I have enjoyed many of the novels in the Inspector Rutledge series. The books take place in the aftermath of WWI. A fact that you may not know: Charles Todd is actually a mother and son writing team.
This is in my TBR pile.
NEW YORK TIMES BESTSELLER • A witty and emotionally charged novel that delves into the heart of a marriage, and how those we love and think we know best can sometimes surprise us the most
I love this series by Deborah Crombie. She is an American but you may well think that she is British when you read her novels. The series is best read in order so as to watch the relationship between Duncan and Gemma but you could always start at the beginning and read this one in its turn. It is the ninth entry in the series. The first book is titled A Share in Death.
Gilly Macmillan is a writer of suspense novels. I read and enjoyed the author’s first book and would like to read this one.
Hope you find a read here that appeals to you.
