Well that hits the spot.Ah, what fun. 60000 words in and only now does my brain decide to come clean about whodunnit....
I've been writing more than one thing at once, but the one that's creaking its way onto Wattpad, chapter by chapter, has a 'series arc' villain in the background, lurking behind the main antagonist, and I've known from the start who it is... And now I find I'm wrong. My original idea was... boring. Now I know who really did it, and why, and so much more interesting. (Cue minor re-writes to make sure I've not put in anything that messes the new idea...)
