In case anyone wonders how things can go when writing -
What I thought was a throwaway line from Chapter Two has now become a major sub-plot in Chapter Twenty-Four, that's going to have assorted repercussions for quite a while.
First 15 chapters are through the second edit, one more edit to go. I've had to go back and fix a couple of issues, courtesy of other throw-away things. (Never mention a character has a pet unless you really mean it - you may have to add said pet in again, when you realize your editor points out - "what happened to the cat?" - and you go, aw, crap. :)
