The six Mitford sisters encapsulate everything that was extraordinary, exciting, glamorous and political about the period between the wars – long an era of fascination for me. In focusing on a different sister for each book, I can explore the changing landscape between 1920 and 1939.
My editor, Ed Wood, spotted a news story about it when we were in the early stages of plotting. He sent it over to me and when I discovered that the murdered woman was on her way to visit friends in the same town that the Mitfords’ real-life nanny’s twin lived in, we had to use it!
I knew that I wanted my heroine to be someone who moved between both upstairs and downstairs, so while the girls are young it makes sense for her to work in the nursery. I have lots of images of the 1920s that I use for ideas, as well as the research that I did for the Downton Abbey books. But ultimately it came down to the fact that I wanted someone I could spend a lot of time with as she will feature in every book of the series – so she is smart, quick and ambitious.
Forensic science for crime-solving began in the early 20th century and remained pretty much unchanged until the discovery of DNA. Dr Spilsbury, who did the post-mortem of the murdered woman at the centre of the book, was considered the ‘father of forensic science’ – he identified decaying human remains in a cellar as those of Dr Crippen’s wife.
Vintage, glamour, war, crime, sisterhood.
