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!.
