Into the plotting stage
I'm a sort of hybrid pantser/plotter, starting off with a spurt of seat of the pants writing until the shape of the story becomes apparent, then going back to plot and rewrite.
It's the plotting stage I am in now with The Man Who Didn't Like People. The story is about a man who deserted his family because he resented his wife having a career and this came to a head when he was made redundent. Twenty years later he has acquired a large amount of money but has learned he has a fatal illness. He returns to find his family and decide whether he should leave the money to any of them. My original concept of the central character has changed dramatically and I am beginning to see that the events of his early life, leading up to when he deserted his family, impacted on them as well as on him. That means his interactions with them as he makes his decision about the money will be largely effected by their reactions to him. It becomes a much more complex story with multiple layers of motivation on all sides. A big part of its success or failure will be how and when I introduce different aspects of the back story.
