It was just the end of the scene which has been swirling around in my head each night as I'm going to sleep, and the fact I haven't been able to finish it (until today) was irritating me.
I think having had to write the synopsis for the Mary Street competition entry, to go with the first three chapters, has got my brain working in the background, building on those ideas, so chapter 4 was nearer my normal 3,000 words per chapter.
I've also discovered, that by having the image board by my desk, my brain never completely switches the story off, so even when I've not been able to get back to the story for a week, having the visuals close by has made it easier to pick up where I left off at my last writing session.
Looking back, the last couple of years have been a big learning experience.
I've found what works best for me and my life, so I'm making progress...
