he other problem some writers have is ending the story. It doesn't matter if it's a happy ending or not, but it has to make sense. There are lots of ways of ending, such as:
The cliff hanger, where we have to wait until the final moment until we know. For instance, the spy who manages to stop the bomb two seconds before it explodes.
The twist, where we are fairly sure about something, but in the final part everything changes. For example, we then learn that this is a fake bomb, and the real one is hidden somewhere else and will explode in five minutes.
The unfinished ending…
