You spill a lot of beans in historical fiction. Crime fiction is about spilling no beans at all. You spill the least beans you possibly can. So because I had already written historical fiction before I was really good at the spilling beans section, but the new skill I had to learn when I was writing Brighton Belle was difficult. I had to avoid the equivalent of shouting, "this character's a murderer! Look who did it!.
Nothing is long ago in an archive, my dear. In the records we treat the dead as same as the living. that’s the whole point of keeping papers. It doesn’t matter if it’s a hundred years or only a few weeks. It’s all filed away, fresh as the day it went under the covers.
