You may recall me saying that I've rewritten this story a few times, well I've done it again. Back when I first came up with the story in the late 90s it had Dave and Nathan and their friendship and I knew where the story would go. There was one aspect that wasn't fully fleshed out, the exact nature of the killer and the reason he kills. It is one aspect that has changed and changed and changed again as I was never really happy with it. Finally the latest tweak seems perfect. Still it will be a couple more chapters before any of that gets revealed.
