Or is it?
All good things must end – including novels. At some point, every writer has wrap up the story and clarify mysteries. Some authors use a character to explain everything. Hercule Poirot gathers all living suspects in the drawing room and describes his deductive reasoning. Harry Potter and Lord Voldemort duke it out with wands and words several times, and Lord Voldemort gets to do most of the talking.
Those final soliloquies are so tempting to write. I had one in my WIP, until I realized it wasn’t necessary. The story still made sense when that dialog was cut. Changes could be made earlier in the novel to release clues. Now the ending focuses on the protagonist’s victory, not the antagonist’s defeat.
