I love it when this happens.
My most recent story, 'Only One Way Out' was supposed to be a ghost story. I've finished and published now and there's not a ghoul or a spectre in sight. Along the way it changed its mind. Instead it's a story (as many of mine seem to be) of a fairly ordinary man doing his best to get through an extra-ordinary situation.
It might still make it as a spooky tale, I have a continuation of it planned but whether or not that will ever be written is another story.
Anyway, if you would like to read it it's available now from Amazon.
