I use Excel to plot my stories (something my mates all make fun of me for). In each draft of each book I mess about with the order of chapters and scenes, add and delete whole sections. ‘Dead Man’s Blues’ had seven drafts. I took screenshots of each draft’s plot as I worked it in Excel and stuck them together here to show the evolution of a plot. Each cell is a chapter and each cell is coloured according to its POV character. Not sure what happened with the 2nd draft.
