Being a writer, the main part of your job is writing and the rest of it is reading what gets published in the genre that you have chosen. I have been looking on many websites for help with crime fiction story structure. There are a lot of plot help, and all are in the Three Act structure, which is fine. Many, in fact all of them are generic templates that follow the usual format. Attached is my Excel spreadsheet where you can outline the story with all the details. I created my own as there were not any avalable for narration single point of view.
