Check out this bite-size writing tip on the end of your story from Esther Chilton’s blog.
Are you struggling to bring your story to a close? Make sure you don’t over-explain your ending e.g. in a crime story, when you reveal who killed the victim, don’t feel as if you have to explain exactly why he/she is the murderer. If you have written your story well, your readers should be able to make all the connections to the clues you’ve woven into the story themselves. A short explanation to underline the revelation is fine, but a lengthy explanation will ruin your story.
