When I've posted excerpts of DIM here previously, I included chapter numbers based on my outline of the novel. This outline is a numbered listing of the chapters along with canon quotations that I intended to use.
I've recently revised the outline a lot, due to my changes about Helen Stoner and the love triangle. The addition of Holmes and Watson's "strange, brief affair" changes much of the plot, and I've decided that Holmes shall confess some things to Watson, but not to Mycroft. So I'll post the outline here to make the plot clearer, so that you can see it in its proper order.
I originally thought I could make Holmes two years younger than normal, born in 1856. However, because I put Holmes into two different universities, I've used up enough years that I have to put him back in 1854. Most chronologists put Holmes in only one university (Oxford or Cambridge), and make up something else to explain the extra seven years before he meets Watson in 1881--a trip to America, a job as an actor, etc.
