Are you writing "live" right now? I love that you dare to do that. I can't help you with an outline, though. Firstly, I'm not that into cozy mysteries, and second, when I outline, I need to have the whole picture in my head before I detail outline a chapter.
No, I'm not writing "live". I have an outline prepared for the complete book, but only two chapters written. That is how I am able to run this experiment. If the experiment fails then I will write the rest of the book myself and post the chapters here.
