~ Agatha Christie ~
Do not fear the dark path your muse might lead you to. Darkness does not necessarily mean bad.
There are times when your muse demands you take another path. Sometimes, you do not even realize it until you have read over your story. Don't scrap it. Post it, or at the very least, pull out the part where you diverged. After all, the mystery muse/story was in you and desperately fought it's way out.
