With the release of The Secret Sauce, I'm sharing a post about how I recreated the setting for The Custard Corpses, my first foray into historical mysteries

The Custard Corpses (and the subsequent books in the series) is set during the 1920s, 1930s and 1940s. I wanted to make the book as authentic as possible, even though I’m not a historian of that time period. When I was first studying history at school, I always found it strange to think of it as history, as I had grandparents who had lived through the 1920s, 1930s and 1940s (my old granny was born in 1901, my mother’s parents in 1920 and my father’s parents in 1926 and 1928). That’s probably why I’ve never written about the period before.

Getting the names right

I wanted to ensure I was using names and places that existed at the time, and I didn’t want to inadvertently make any silly mistakes – a few beta readers pointed out I was using metric measurements, when they should have been imperial in the 1940s. They thought it was sweet that I’d never known the world of imperial numbers (and money). I still find 'old' money incredibly confusing.

Maps and train routes

So, I spent quite a bit of time hunting down random facts; maps of the time period, tram and train routes (which you can find online), pictures of cars, police uniforms at the time (and this fab resource which lists police archives), advertisements of the period and also editions of the Picture Post magazine. At one point, I wanted a celebrity scandal, and there it was, on the cover of a magazine.

Newspaper Archives

I was amazed by the information that I could find by accessing archives ( and also that which I couldn’t find), and I was especially impressed by the ‘history’ section on the Birmingham.gov website, and by those local newspapers that have archives available online – such as the Inverness newspaper and the Birmingham Mail. There’s also a whole aerial photo website that I could have used, but I couldn’t quite work out how to get the most out of those, but I have since had more success. 

Family memories

I was also fortunate in that I set the book in a place where I have childhood memories, and also that a family member spent their early years in Erdington. It was funny to realise the parts that they especially remembered – such as the fact that some of the buses were still open-topped at the time, and the liveries that buses were decorated with. The Birmingham that I remember is very different to the one that exists now, and the one that existed in the 1940s. My memories of Birmingham consist of the dodgy car park we used, the train journey we used to take in the old carriages with individual doors (they were old in my day) and shopping for jeans.

I also made some use of the 1911 census records, and the Office for National Statistics spreadsheet, which lists all the most popular names in decades. It made it easy to devise names for the characters. Since I wrote the first book, the 1921 census records have also been released. It also helped that while the 1940s is ‘history’, it’s much more relatable to me than the period before 1066, when I usually set my stories, so provided I didn’t use the internet in the story itself (and only as a research tool), or refer to cms, it was just about authentic, I hope. It also allowed for the use of cars and telephones, which was very exciting. No muddy horses needed to deliver a message:)
