The Child's Child by Barbara Vine (Ruth Rendell)
I did not remember requesting this book from the library when I picked up my books the other day. BUT I am glad that I did. I really enjoyed this book. I cannot remember reading anything by Ruth Rendell before but I probably have.
This is the story of a brother and sister named Andrew and Grace Eaton. They inherit a house from their grandmother. They decide to move in and share the house. Grace is working on her thesis about unwed mothers in the past. A friend contacts her about a novel that his father wrote but never had published, The Child's Child, which is set a few years after World War 1. Andrew's boyfriend, James moves into the house and they witness the murder of a friend. This shakes James to the core and also upsets everything in the house. Grace finally reads the novel and discovers the story parallels events in their lives.
